Convolutional Neural Network experiment

Wed, Apr 6, 2016

The video shows a little experiment I have been working on in the last days: training a convolutional neural network using Keras and Theano to “follow” a sidewalk. The output of the classifier are three probabilities that represent if the best option is to continue forward, turn left or turn right (the overlaid green arrow correspond to the highest probability).

The dataset is still very small, I have just recorded three 30 seconds videos on three different streets on my neighbourhood (two for training, one for testing). In the above testing video the classifier has a promising 92% accuracy. Still to be evaluated how the performance change with a greater variety of environments.
