A simple neural network with Python and Keras - PyImageSearch

In today's blog post, I demonstrated how to train a simple neural network using Python and Keras. We then applied our neural network to the Kaggle Dogs vs. Cats dataset and obtained 67.376% accuracy utilizing only the raw pixel intensities of the images. Starting next week, I'll begin discussing optimization methods such as gradient descent and Stochastic Gradient Descent (SGD). I'll also include a tutorial on backpropagation to help you understand the inner-workings of this important algorithm.
