keras-sparse-check

This code is for comparison of training on dense vs sparse data used in neutrino experiments. In common.py file there are:

• code that reads data into dense or sparse format. In case of dense format data is stored in numpy array. For sparse representation data is stored as list of sparse scipy matrices
• code that creates network
• sparse data generator - it generates batches with dense data based on list of sparse matrices

To run comparison please run:

• for training with dense data python train_dense.py
• for training with sparse data python train_sparse.py

Prerequisites

1. You have installed keras, numpy, scipy.
2. Please provide proper paths to your data in functions: get_y_data, get_x_data_sparse, get_x_data_dense in common.py file. This example is for data with 3 classes and images size is 32x32 with depth 1.
