OOP for Terminal + Uncor Speed Sampling

Added

• Classdef for CorTerminalModel
• RUN_terminal is an example RUN script demonstrating how to use the new CorTerminalModel class
• aind2sub, discretize_bayes, hierarchical_discretize, setTransitionPriors are various functions to help sample the Bayesian networks

Changed

• RUN_OOP renamed to RUN_uncor
• Update primary README.md with information about the correlated terminal model and to better distinguish it from the RADES-based correlated extended model
• UncorEncounterModel/track sets minimum and maximum speed thresholds for rejection sampling based on the probability distribution of the speed bins, rather than the minimum and maximum speeds of the model structure. In release [2.0.0], the conventional uncorrelated models released in [1.3.0] had a maximum speed of 300 knots with a minimum speed of at least 30 knots for the fixed-wing models. The speed ranges for the different uncorrelated models are now the following:

Aircraft Type	1200-excluded	1200-only
Fixed-Wing Multi-Engine	[120, 300]	[90, 300]
Fixed-Wing Single Engine	[60, 250]	[60, 250]
Rotorcraft	[30, 165]	[30, 165]

October 2021 - Uncor OOP

Added

• Classdef for EncounterModel superclass and UncorEncounterModel class
• RUN_OOP is an example RUN script demonstrating how to use the new UncorEncounterModel class
• IdentifyGeographicVariable to calculate the geographic domain variable, G

Changed

• Update EncounterModelEvents with property validation functions
• Update em_read to calculate bounds_initial and cutpoints_inital
• Startup script add em-core to path
• Various functions updated to use addParameter instead of addOptional when using the MATLAB input parser
• .gitignore updated to ignore .png files in the output directory

Removed

• None

Fixed

• End of line whitespace in ASCII files for boundaries parameters had extra whitespace leading to incorrect reading of data by em_read. This bug was introduced in 1.4.0 and previous versions were note effected.

July 2021 - Terminal Model and Improved Performance

Added

• Correlated terminal encounter models based on terminal area radar or OpenSky Network processed tracks

Changed

• Completely rewrote em_read so it no longer assumes a strict model structure with a specific set of model fields organized in a specific order
• Changed inputs to em_sample, dbn_sample, dbn_hierarchical_sample to be a struct of model parameters instead of individual parameters. This improves flexibility and readability.
• em_read now calls bn_sort and calculates variable order for initial and transition networks. Calculating these upfront significantly improves performance because bn_sort was a bottleneck.
• Reorganized dbn_sample to minimize repeat function calls and calculations
• dbn_sample now longer calls select_random because it was inefficiently adding overhead due to the multiple calls to rand and cumsum. This wasn't inefficient because cumsum(weights) don't change for the dynamic variables
• More documentation on the terminal encounter model

Fixed

• em_read to use strfind instead of deprecated findstr when calculating the temporal map
• em_read searches for t+1 and t-1 labels when creating the temporal map

March 2021 - OpenSky Updates

• Updated OpenSky models organized based on 1200 code
• Added G = 5 (Canada) to OpenSky models
• Added categorical variables to README
