This post continues from neural network basics part 1: Layers Matrix Multiplication. This post therefore assumes that you have basic knowledge on what a neuron is. Why Add an Activation Function? In neural network basics part 1: Layers Matrix Multiplication I covered matrix multiplication and defined a simple neural network as the weighted sum of inputs with the equation: [...]

## Neural Networks Learning The Basics : Layers, Matrix Multiplication

This blog post takes a close look at the first fundamental concept of a neural network that I introduced briefly in my previous post. The layers. Layers are the building blocks of a neural network and contain the network’s knowledge. In order to achieve our goal one needs to first understand what a neural network [...]

## My Journey To Data Science

Data Science is a new field and it is very broad. To keep things simple, the heart of Data Science lies in the implementation of complex algorithms to data. This is done to discover some underling relationships between variables to predict a certain outcome. The primary goal is to enable “intelligent” machine driven decision making. [...]
