WebJul 3, 2016 · 13. Yes you are right. In Keras batch_size refers to the batch size in Mini-batch Gradient Descent. If you want to run a Batch Gradient Descent, you need to set the batch_size to the number of training samples. Your code looks perfect except that I don't understand why you store the model.fit function to an object history.
