# Caffe-Tools

Tools and examples for pyCaffe, including:

* LMDB input and output and conversion from/to CSV and image files;
* monitoring the training process including error, loss and gradients;
* on-the-fly data augmentation;
* custom Python layers.

The data used for the examples can either be generated manually, see the documentation
or corresponding files in `examples`, or downloaded from [davidstutz/caffe-tools-data](https://github.com/davidstutz/caffe-tools-data).

Also see the corresponding blog articles at [davidstutz.de](http://davidstutz.de).

## Examples

The provided examples include:

* [MNIST](http://yann.lecun.com/exdb/mnist/): [examples/mnist.py](examples/mnist.py)
* [Iris](https://archive.ics.uci.edu/ml/datasets/Iris): [examples/iris.py](examples/iris.py)
* [Cifar10](https://www.cs.toronto.edu/~kriz/cifar.html): [examples/cifar10.py](examples/cifar10.py.py)
* [BSDS500](https://www2.eecs.berkeley.edu/Research/Projects/CS/vision/grouping/resources.html): [examples/bsds500.py](examples/bsds500.py)

Note that the BSDS500 example is **work in progress**! The corresponding data can
be downloaded from [davidstutz/caffe-tools-data](https://github.com/davidstutz/caffe-tools-data).
See the instructions in the corresponding files for details.
