I wanted to use a deep neural network to solve something other than a “hello world” version of image recognition — MNIST handwritten letter recognition, for example. After going through the first tutorial on the TensorFlow and Keras libraries, I began with the challenge of classifying whether a given image is a chihuahua (a dog breed) or ... Oct 18, 2018 · The input for AlexNet is a 227x227x3 RGB image which passes through the first convolutional layer with 96 feature maps or filters having size 11×11 and a stride of 4. The image dimensions changes to 55x55x96. Then the AlexNet applies maximum pooling layer or sub-sampling layer with a filter size 3×3 and a stride of two. Keras is a popular and user-friendly deep learning library written in Python. The intuitive API of Keras makes defining and running your deep learning models in Python easy. Keras allows you to choose which lower-level library it runs on, but provides a unified API for each such backend. Currently, Keras supports Tensorflow, CNTK and Theano ...
