Specifically, I've moved the logic from `_SktimeForecaster` and the forecasting horizin mixins into `BaseForecaster`, and adopted uniformly the principle of having a public method (`fit`, `predict`, etc) with checks/plumbing, dispatching to a "core logic" version (`_fit`, `_predict`, etc) where validated arguments can be assumed. The burden on extenders becomes much lighter, since it is now possible to only focus on the "core logic" implementation, instead of having to keep in mind a myriad of inconsistent and constantly shifting conventions in checks and other plumbing. As side effects, if we get this right, this should make a few things on the roadmap easier: * the extension guidelines #464. Right now, the aforementioned implicit conventions are too many and intricate to write useful extension guidelines, in my opinion. * extending to the multivariate case * input/output checks and the eternal data container discussion, this can go in the plumbing As a proof-of-concept regarding ease of extension, this PR also contains a highly annotated extension template in the `extension_templates` folder. In terms of review, the key file is `forecasting/base/_base`, with corresponding changes (contraction and deletion) in `base/_sktime`. I've tried to keep the interface consistent as much as possible (only changing internal logic). Interface contracts with all the earlier estimators are still honoured, via loopthroughs and default behaviour that ensures that everything still works if `fit`, `predict` etc are overridden by the current descendants, as opposed to `_fit` and `_predict`. The only change I had to made to descendants is set `self._is_fitted=False` at the start of `fit`, which is a minimally invasive change that's also separately reviewable as PR #941. * Properly process random_state when fitting Time Series Forest ensemble in parallel (#819) * Properly process random_state when fitting ensemble in parallel * Fix test for a new random_state initialization * Suggested changes Co-authored-by: Oleksii Kachaiev <okachaiev@riotgames.com> Co-authored-by: Markus Löning <markus.loning@gmail.com> Co-authored-by: mloning <markus.loning.17@ucl.ac.uk> Co-authored-by: Matthew Middlehurst <pfm15hbu@uea.ac.uk> * Exemplary concrete estimator refactor post interface refactor, of NaiveForecaster (#953) This is an exemplary refactor of a concrete estimator class, `NaiveForecaster`, to explore how general concrete forecaster refactors would work, along the lines discussed in #912. This PR changes: * `_BaseWindowForecaster` still inherits from `BaseForecaster` directly, and already looked extension spec compliant (no overrides, no tags) * `NaiveForecaster` inherits from `_BaseWindowForecaster`, and has been made extension spec compliant by adding the `requires-fh-in-fit` tag, and moving core logic from `fit` to `_fit`, while avoiding to override `fit` * it adds one line in `BaseForecaster.fit`, as a general change: the `cutoff` is set to the latest `y` index using `_set_cutoff`. This is done pre-`_fit`, which could override the set cut-off. * catch22 Remake (#864) * catch22 remake * catch22 numba imports * c22pr formatting 1 * c22pr formatting 2 * c22pr formatting 3 * c22pr formatting 4 * catch22 example import fix * Lower n_estimators for interval example * almost equal for c22 test * faster tests and examples * faster tests and examples 2 * c22 n_jobs and cif alternative classifiers * code quality * outlier normalisation * 1 line * inclusion in init * cacheing for numba, pickle fix for cit * c22f test update * cif comments * base estimator change * update cif tests * rounding catch22 in cif * stray prints * os diff fix attempt * cq * test updates * cq2 * docs and estimators update * c22f outlier norm false * suggested pr changes * move tsf CIT to contrib * cq1 * c22 private functions Co-authored-by: Tony Bagnall <ajb@uea.ac.uk> * Fix fh in imputer method based on in-sample forecasts (#861) * Changed fh_ins selection. * Created a function for univariate imputation based on the forecaster. * Turned _univariate_forecaster() into a function rather than a method. Renamed it and corrected the loop and if statements locations. * Review, suggestions * Fix the docstrings by running pydocstyle. * minor changes Co-authored-by: mloning <markus.loning.17@ucl.ac.uk> Co-authored-by: Markus Löning <markus.loning@gmail.com> Co-authored-by: Martin Walter <mf-walter@web.de> * Update plot_series to handle pd.Int64 and pd.Range index uniformly (#892) * check for indices added * typecasting modified * check for indices added * check for indices added * removed union operation from check_consistent_index_types * Updated docs to comply with pydocstyle * comments modified * Trigger CI Checks * Add unit test * Minor fixes after self-review * Fix tests Co-authored-by: Sakshi Bhasin <sbhasin@sbhasin-ltmo42k.internal.salesforce.com> Co-authored-by: mloning <markus.loning.17@ucl.ac.uk> * Update contributors * adding fkiraly as codeowner for forecasting base classes (#989) adding fkiraly as additional codeowner for `forecasting.base` directory * added Martina's homepage/contact link * Bump nbqa version (#998) * Feature/information criteria get_fitted_params (#942) Adding the available information criteria (AIC, AICc, BIC, HQIC) for various forecasting algorithms. TBATS and BATS did not have a get_fitted_params method so I added it in the adapter there. * refactors HCrystallBall Forecaster (#1004) refactor of HCrystalBallForecaster, see #955 * Refactor Prophet (#1005) refactor of Prophet forecaster, see #955 * Forecasting tutorial rework (#972) This pull request contains a re-work of the forecasting tutorial which should make it more structured, complete, and accessible - from what right now looks like a patchwork piece that has organically proliferated. Main changes: * re-structuring in chapters - basic workflows, selected estimators, composition (reduction, pipelines) * expanded explanation of what happens in sections/chapters, added some code for object inspection * factored out the "pitfalls" in a separate notebook, also expanded - focus is now on use of `sktime` primarily * refactors PmdArimaAdapter (#1016) too new forecaster interface, see #955 * refactors tbatAdapter (#1017) too new forecaster interface, see #955 * Added two new related software packages (#1019) * Fixing soft dependencies link (#1035) * Refactors ensembler, online-ensembler-forecaster and descendants (#1015) as per #955 * Refactor reducer (#1031) according to #955 * refactors statsmodels, theta forecaster (#1029) according to #955 * Refactoring Stacking, Multiplexer, Ensembler and TransformedTarget Forecasters (#977) as per #955 * Refactors polynomial trend forecaster (#1003) according to #955 * Forecasting tutorial rework - with cell content (#1037) This is the forecasting tutorial with all cell contents, see #972. No other changes except cell content in the main forecasting tutorial added. * Revert "Forecasting tutorial rework - with cell content (#1037)" (#1051) This reverts commit 19e86b8fcf3b6d96c967e91657f63281f40907aa. * Multivariate Detrending (#1042) Fixes #1030 . See also #1038 . This would be a quick fix to #1030 as it adds functionality for multivariate series to the detrender. As discussed with @mloning I took inspiration from how this was done for the imputer. But I also like the idea to have compositions for multivariate series as it is described in #1038 * Update contributors * Added tuning tutorial to forecasting example notebook - fkiraly suggestions on top of #1047 (#1053) Changes to forecasting tutorial notebook by @aiwalter, with contributions by @fkiraly: new section 3.4.2 on advanced pipeline building, introducing `OptionalPassthrough` for autoML * default tags in BaseForecaster; added some new tags (#1013) Adds some default tag values in `BaseForecaster` - these are automatically inherited via `_all_tags`. Also adds two new tags that I anticipate we will need: * `"X-y-must-have-same-index"` - do `X` and `y` need to have the same index? * `"enforce-index-type"` argument to `check_X`/`check_y` if needed - this has to be a tag now, see the problem in #1005 . I've also added these new tags to the extension template. This PR also: * corrects a minor bug: mis-spelled tags in the extension template * adds the new tags to the allowed tags in tests * removes the requirement for tags to be boolean * Clustering (#1049) * basic functionality * basic kmeans implementation * Improved the base code for k means * Improved the base code for k means * Renamed misslabeled mixins * Removed accidental edit * Delete pyvenv.cfg * Delete python3.9 * Delete easy_install * Delete easy_install-3.9 * Delete python3 * Delete python * Delete pip * Delete pip3 * Delete pip3.9 * Fixed linting * Barycenter averaging implemented * Update .all-contributorsrc * Update .all-contributorsrc * Fixed tests * Fixed warning from sklearn * Added k medoids and reformatted structure * basic functionality * basic kmeans implementation * Improved the base code for k means * Improved the base code for k means * Renamed misslabeled mixins * Removed accidental edit * Delete pyvenv.cfg * Delete python3.9 * Delete easy_install * Delete easy_install-3.9 * Delete python3 * Delete python * Delete pip * Delete pip3 * Delete pip3.9 * Fixed linting * Barycenter averaging implemented * Fixed tests * Update .all-contributorsrc * Update .all-contributorsrc * Fixed warning from sklearn * Added k medoids and reformatted structure * rebased from main * first refactor of experiments * some doc strings added * removed dependency and reverted accidental delete * fixed base estimator * adding all to clustering directory * clustering examples * Update clustering_examples.py * updated defaults * Updated docstrings * clustering experiments changes * add check_X to partition clusterer * formatting * formatting 2 * remove mystery whitespace comment * Final cluster update before Main (#979) * Followed feedback given on pr. Additionally added the unit test for BaseCluster as a new estimator * fixed error in merge * Suggested changes and improved unit tests (#1000) * Followed feedback given on pr. Additionally added the unit test for BaseCluster as a new estimator * fixed error in merge * Made Markus changes and improved unit tests * fixed softdepend error * removed extra * reverted accidental change * fixed bug * Removed softdependency * Clustering (#1045) * Reverted everything and added only the files I've changed back in to hopefully fix the pr * Reverted everything and added only the files I've changed back in to hopefully fix the pr * Changed name back * Update .all-contributorsrc * Clustering small changes (#1054) * Reverted everything and added only the files I've changed back in to hopefully fix the pr * Reverted everything and added only the files I've changed back in to hopefully fix the pr * Changed name back * Final Markus changes and updated some docs * fixed linting * removed upsupport annotations * softdependencies updated * softdependencies updated Co-authored-by: Chris Holder <chrisholder987@hotmail.com> * Add ThetaLines transformer (#923) * added empty theta.py file * Added transform and _theta_transform methods * Added input checks and examples to the docstr of the class * added simple tests * Updated _check_theta function * Updated _check_theta function and test_theta.py * Added test and example theta_transform.ipynb * Updated tests, theta.py and example notebook * updated _check_theta to return list * Updated example notebook and transform method * Fixed kernelspec in ipynb * Updated _tags and example docstr * Updated example docstr * minor clarifications in forecasting extension template preamble (#1069) * BaseCluster class issues resolved (#1075) * renamed `BaseCluster` to `BaseClusterer` * `fit_predict` is now in `BaseClusterer`, deprecated mixin * sktime-registry - without moving all_estimators (#1067) This PR moves the following things to a central `sktime` registry: * scitype strings, estimator base class references and look-up * tag names, the scitype which the tag is for, expected tag types The registry also records plain English explanations, so it's runtime inspectable without having to dive through code files and comments in the code. This should simplify test workflows (e.g., in `_config`), and retrieval workflows such as `all_estimators` or the automated overview of learning algorithm #704, filtered, say, by scitype or tag. * Forecasters re-factoring: BaseGridSearch, ForecastingGridSearchCV, ForecastingRandomizedSearchCV (#1034) Part of refactor #955 #### What does this implement/fix?

Co-authored-by: Tony Bagnall <ajb@uea.ac.uk> * Update release script (#1135) * rework of installation guidelines (#1103) [DOC] rework of installation guidelines * Update README (#1024) Updates to the GitHub `README` landing page: * updated abstract; refers to community activities too * index at the start of the page * tabular overview of supported learning tasks and non-estimator object; links to relevant artefacts such as tutorials, documentation, etc * clearer vision statement * extended new contributors section to be more clear on how to contact us or to contribute On the technical side, this changes the `README` from `rst` to `md` (for full emoji support 😃 ) * added link to distances extension template on README * revert change in distances -> kernels * fixed distance/kernels link on landing page * coherent interface for data_processing (panel conversions) module (#1061) This PR introduces a clean interface for the panel data types conversions module. This is fully downwards compatible, but adds the `convert(from, to, scitype)(what)` syntax on top of the `utils.data_processing` module. This should provide users with an easy way to convert their data into the `sktime` required format for TSC without having to sift through the code to find the right converter utility. A number of conversions are missing, and some are lossy, so this may be a good start for future "good first issues". * Add roadmap from dev days workshop (#1145) Updates the roadmap based on the discussion from the 2021 sktime dev days. * Fix pydocstyle config (#1149) * adding example in docstring of KNeighborsTimeSeriesClassifier (#1155) In the docstring of `KNeighborsTimeSeriesClassifier`: added example and modified description of `weights` in `Parameters`. * BaseObject and rework of tags system, including dynamic tags (#1134) Rework of PR #1099 which is in turn a rework of PR #891 (by @RNKuhns), based on discussion recorded in #981 on tags. Adds a `BaseObject` class which adds dynamic tag functionality. `BaseObject` contains `BaseEstimator` functionality sans `fit` state change related interfaces. The new functionality replaces the inconsistent mixture of old interface points (`all_tags`, `has_tag`) in all downstream dependencies. post-PR, tags work like this: * each class will have "class tags", stored in the content of the class variable `_tags: dict`. Individual class tags are considered to override each other as per normal nested inheritance. E.g., if a parent class and the class have different values for a class tag, the younger class' class tag value counts. * each object can, in addition, have dynamic tags, in the object variable `_tags_dynamic: dict`. These are expected to be initialized in the constructor, for instance in cases where behaviour described by tags depends on components or hyper-parameters. Dynamic tags are always considered to override the class tags - e.g., if the object's class or a parent class have a static tag of the same name, the dynamic tag's value overrides any class tag's value. The new tag related methods make use of this inheritance logic are as follows. class methods: * `get_class_tags()` collects all class tags and their values and returns them as a `dict` (keys = tag names, values = tag values). It overrides values precisely as described above, in the return dictionary. This replaces the old `_all_tags`. * `get_class_tag(tag_name, tag_value_default=None)` retrieves the value of an individual tag with name `tag_name`, and optionally allows to specify a default value if the tag is not found. The inheritance/override logic is the same as in `get_class_tags`. object methods: * `get_tags()` collects all class tags and dynamic tags and their values and returns them as a `dict` (keys = tag names, values = tag values). It overrides values precisely as described above, in the return dictionary. * `get_tag(tag_name, tag_value_default=None)` retrieves the value of an individual tag with name `tag_name`, and optionally allows to specify a default value if the tag is not found. The inheritance/override logic is the same as in `get_tags`. * `set_tags(**tag_dict)` sets dynamic tags according to keys (=tag names) and values (= tag values) in the argument dictionary. It is expected to be used in constructors typically. * `mirror_tags(estimator, tag_set=None)` is a shorthand version of `set_tags`, where it sets tags according to their `get_tag` values in `estimator`. The tags that are mirrored/copied in this way can be restricted by specifying a list of tag names in `tag_set`, otherwise all tags are copied over. The mirroring is by-reference and not by-value (if the type allows this), but tags are not expected to be mutated. * add examples in docstrings in classification module (#1164) * Refine the Docstrings for BOSS Classifiers (#1166) * Update docstring style * Refined docstring * Update See Also and Examples * Fix examples and add missing docstring info * Push changes to cBOSS docstrings * Add annotation ext template (#1151) * Add annotation ext template * Minor fixes * Fix docstrings * unit test for absence of side effects in estimator methods (#1078) This implements #1073, a test for estimator methods not having side effects. New method is `check_methods_have_no_side_effects` in `estimator_checks`. It also adds a utility function `deep_equals` for tests, which tests for equality of deep list/tuple constructs containing pandas, numpy, and/or primitives. * ForecastingHorizon is_relative detection on construction from index type (#1169) This PR makes minor changes to `ForecastingHorizon` construction behaviour, to address the user frustration highlighted by @Flix6x in #1167. It also fixes all the docstrings. Previously, regarding `ForecastingHorizon` construction behaviour: * the default `is_relative` in construction of `ForecastingHorizon` was `True`, which caused an error to be thrown when constructing a `ForecastingHorizon` with supported absolute index types that were not also relative types, like `pd.DatetimeIndex`. * when an index of such a type was passed to the `fh` argument of `fit` or `predict`, the same error would be thrown, since all indices were converted to `ForeceastingHorizon` with the default setting `is_relative=True`. The new construction behaviour is as follows: * the constructor allows the `is_relative` argument to be `None` - in this case the value of the `is_relative` argument is inferred: if the index is a supported relative index, it's `is_relative=True`. Otherwise, if it's a supported absolute index, it's `is_relative=False`. * This covers the case of `pd.DatetimeIndex`, which now can be passed to `fit` and `predict` without the estimator complaining. * bugfix set_tags (#1179) Bugfix to `BaseObject.clone_tags`: `set_tags` was called incorrectly from `clone_tags` without the kwargs symbol. * Add estimator overview to docs (#1138) * Reformatted done * Added learning algorithm creating dynamic estimator overview with sphinx generated docs * Added html files * fixed minor changes * Updated algo_list.py * Transferred to docs file and updated them * Refactoring files * Refactoring files * updated the extension to estimator_overview_table.html * possible solution * update dependencies * update dependencies * update dependencies * update dependencies * more changes * Add JavaScript and HTML to filter estimator overview (#1153) * adds a searchable estimator overview table in markdown * the table is generated automatically every time the docs are build based on the source code * minor updates to the docs deployment * Fix docstrings Co-authored-by: afzal442 <afzal442@gmail.com> Co-authored-by: Tony Bagnall <ajb@uea.ac.uk> Co-authored-by: Juan Luis Cano Rodríguez <hello@juanlu.space> * Add ExponentTransformer and SqrtTransformer (#1127) * Added SqrtTransformer to docs * Added sqrt.py to CODEOWNERS * Refactored to PowerTransformer * Fixed SqrtTransformer __init__ * Unit tests for raised errors * Fixed SqrtTransformer docstring * Renamed PowerTransformer to ExponentTransformer * Add funding (#1173) * add funding * Change wording * remove mloning * fix wording * Forecasting support for multivariate y and multiple input/output types - working prototype (#980) This PR introduces multiple input/output type support for `X` and `y` in forecasters, including generic support for multivariate `y`, i.e., `pd.DataFrame`, and the possibility to pass `np.ndarray` and `pd.Series` to either argument. This is loosely based on the design in [STEP no.5](https://github.com/sktime/enhancement-proposals/tree/main/steps/05_scitype_based_IO_checks) and subsequent discussions with @mloning around #1074. The key ingredients are: * converters parameterized by from, to, and as - in the `convertIO`module. Besides the obvious conversion functionality, the converters can be given access to a dictionary via reference in the `store` argument, where information for inverting lossy conversions (like from `pd.DataFrame` to `np.array`) can be stored * a new tay `y:scitype` which can be `"univariate"`, `"multivariate"`, or `"both"`, indicating what type of `y` are supported (multivariate here means 2 dims or more) * new tags which encode the type of `y` and `X` that the private `_fit`, `_predict`, and `_update` assume internally - for now, it's just one type and not a list of compatible types * some logic in the public "plumbing" area of `fit`, `predict`, `update`, which converts inputs to the public layer to the desired input of the logic layer and back * expanding tests and checks that ensure that errors are raised when the wrong types are passed, and changes that ensure the new allowe inputs such as `pd.DataFrame` are allowed rather than blocked by the checks * forgot X_inner_mtype in extension template * bugfix - pd.DataFrame->pd.Series conversion missing (#1187) The pd.DataFrame->pd.Series conversion was incorrectly missing from `_convertIO` (from #980), this is fixed now. Merging quickly since urgent bugfix * Minor update to See Also of BOSS Docstrings (#1172) * Update docstring style * Refined docstring * Update See Also and Examples * Fix examples and add missing docstring info * Push changes to cBOSS docstrings * Fix See Also links in docstring Co-authored-by: Matthew Middlehurst <pfm15hbu@uea.ac.uk> * STSF test fix (#1170) * stsf fix * docs Co-authored-by: Tony Bagnall <ajb@uea.ac.uk> * change to classification experiments (#1137) remove the need for cython to run classification_experiments, set up example problem from datasets/data/UnitTest * Add annotation to docs (#1156) * Complete docstring of EnsembleForecaster (#1165) * Refactored class docstr, added example * Deleted blank lines after fn docstrings * Fixed docstring example * bugfix np.ndarray type typo in convertio (#1191) * Registry lookup - all_estimators refactor, and new all_tags (#1196) This PR consolidates registry lookup in the `registry` module: * `all_estimators` is moved to the `registry`, with all dependencies referencing the new location * `all_estimators` has a new argument `filter_tags`, which allows to filter by tags (incl scitypes, capabilities, etc); order of arguments has been changed so filtering is first, output format args last * new lookup function `all_tags`, which allows to lookup tags, possibly filtered by estimator type * both lookups have a new argument `as_dataframe`, which allows for pretty printing in jupyter notebooks, useful for the standard user archetype * Transform classifiers (#1180) * transform classifiers p1 * transform classifiers p2 * transform classifiers notebooks * signature config fix * dependencies, api and test docs * feature based docs p1 * mp fix * tsfresh docs * docs cont. * mp test config fix * more doc fixes * it has to be one 1 line apparently? * pycharm editing some random imports * reintroduce deprecated files. matrix profile estimator change * soft dependencies and matrix profile config * explicit deprecation comments * default estimator fix * cant even get 0.9 * [DOC] Adding table of content in forecasting tutorial (#1200) * Data types module, collating conversions, mtype inference, checks, register (#1201) This PR collates data type and conversion related concerns in its own module, `datatypes`. The functionality moved to `datatypes`: * series conversion functionality formerly in `forecasting.base.convertIO` * panel conversion functionality formerly in `utils.data_processing._panel` All references to the old locations have been replaced by references to the new locations. New features enabled by this move: * there is just a single `convert` function, for both `Series` and `Panel` scitype * nested, extensible module structure which is by scitype, e.g., `panel` and `series` New functionality, partially implemented for extension: * register of mtypes with explanation, to be complemented by docs * central fixture generation function `get_example` which produces fixtures of the same "scientific content" but a specific mtype, for external tests, and bulk testing of conversion or mtype inference functionality * Format setup files (#1236) * Set up fails the tests * Change strings from '' to "" * setup docstring, since Im here * docs * god I hate docstrings * Update setup.py * removed format check from index test (#1193) This addresses problem no.3 in #1192 - removing a data frame format check from the test on "indices are equal" which is off-topic in the test, and causes all combined uni/multivariate forecasters (with `scitype:y = both`) to fail. * prediction interval NotImplementedError moved to BaseForecaster (#1195) This addresses problem no.1 in #1192, by: * moving `NotImplementedError` raised for prediction intervals to `BaseForecaster`, dependent on a new boolean capability tag `"capability:pred_int"` * adding the tag with value `True` to all forecasters which have the capability to return prediction intervals; added it in `clone_tags` of tuning * updating the test `test_predict_pred_interval` so it checks both for whether prediction intervals are returned, or `NotImplementedError` is raised, explicitly dependent on `"capability:pred_int"` * Clustering experiments (#1221) * minor change to tidy up file writing format * format 1 * format 2 * format 3 * format 4 * more on write_results_to_uea_format * format 4 * experiments redesign * moving clustering experiments out of contrib * formatting 1 * format 2 * format 3 * format 4 * format 5 feel my pain * Format 5 * docstrings 1 * docstring 2 * docstring 3 * docstring 5-ish * docstring 5 * tidy up load_and_run docstring * import error in elastic_ensembl_from_file * try a rebuild * make some methods "private" * Update basic_benchmarking.py * move stratified sampling into new file "sampling" * docstrings * benchmarking docstring * adding unit tests for experiments * docstrings * Update test_experiments.py * update * Update test_experiments.py * docstrings, always docstrings * docstrings * remove test harness, add Example in docstring * refactor resampleID * fix tests * formatting * Examples formatting * remmove Experiments to see if it passes * added a root directory to setup.py to help make loading simpler * style update for setup.py to pass tests * Update setup.py * Update setup.py * Update experiments.py * Update test_experiments.py * Update setup.py * give up on Experiments for now * will it ever end? :) * seems not * spaces, too many spaces * Update experiments.py * Update experiments.py * correct import set_classifier * Update experiments.py * back to docstrings * docstrings, gotta love em * Update test_experiments.py * Update test_experiments.py * Update test_experiments.py * leave classification for now, to sort out soft dependencies * formatting 5 billion * my IDE disagrees, but nevermind * It has me doing docstrings for setup.py now .... * Another can of worms accidentally opened * docstringsdocstringsdocstrings * why does pycharm auto indent incorrectly? * I'm really confident this time .... * dashed on the cliffs of unused import * I am merging this bugger as soon as it passes! * so the linting makes changes that break the setup.

The return in the multivariate case is a 2D dataframe with column multi-index (column, variable), otherwise in analogy to the univariate case. This also addresses one of the post-multivariate PR issues from #1192. * Fix appveyor CI (#1253) * Data io (#1248) * remove direct reference to datasets/base * refactor datasets/base.py -> datasets/data_io.py * Update add_dataset.rst * Add UnitTest to the included datasets * format and docs * Update test_muse.py * tedium * direct distances.base reference in notebook * pedantry * no idea on this one * Update dictionary_based_classification.ipynb * getting a bit surreal now * forgot the init for load_unit_test * correct notebook, make data_io private * end of file weirdness * Update interval_based_classification.ipynb * Update minirocket.ipynb * Update rocket.ipynb * end of file nonsense * Update test_time_series_neighbors.py * Update test_time_series_neighbors.py * [DOC] add conda-forge maxdep recipe to installation docs and readme (#1226) * Update contributors (#1243) * bug fix in tutorial documentation of univariate time series classification.
