no code implementations28 Mar 2017 Shun Yang, Wenshuo Wang, Chang Liu, Kevin Deng, J. Karl Hedrick

We collect a large set of data using The Open Racing Car Simulator (TORCS) and classify the image features into three categories (sky-related, roadside-related, and road-related features). We then design two experimental frameworks to investigate the importance of each single feature for training a CNN controller. The first framework uses the training data with all three features included to train a controller, which is then tested with data that has one feature removed to evaluate the feature's effects.
