14.05.2020 · A neural network’s architecture is derived from the structure of a human brain while from a mathematical point of view, it can be understood as a function which maps a set of inputs to desired outputs. The main idea of this post is to understand this function in detail and implementing it in python. A neural network comprises of 7 Parts ...
2 - Overview of the Problem set¶. Problem Statement: You are given a dataset ("data.h5") containing: - a training set of m_train images labeled as cat (y=1) or non-cat (y=0) - a test set of m_test images labeled as cat or non-cat - each image is of shape (num_px, num_px, 3) where 3 is for the 3 channels (RGB).
