Neural Network From Scratch
Neural Network
Neural Network Algorithm
Is it really a black box?
Neuron in a neural network
Can approximate any function
Algorithm
Why Neural Network from Scratch
Understanding the fundamentals
Mathematics and statistics
No dependency
Introduction
Concepts used
Dot Product of Matrix
Linear Algebra in Deep Learning
Not all matrices are eligible for multiplication
m×n by n×p matrix equals to m×p matrix.
Concepts used
Activation Function
Determine the output of a neural network
Sigmoid function is an activation function
"S" shaped curve.
Concepts used
Sigmoid Derivative
Derivative of the sigmoid function
Sigmoid multiplied by one minus the sigmoid
Backpropagate through sigmoid activation functions
Neural Network
Diabetes data with Glucose and Blood Pressure
Neural Network
Chain Rule
Calculus Formula
Derivative of a composite function
Chain of derivatives
Neural Network
Implementation Steps
Import the required libraries
Load the data
Separate the features and label
Define the sigmoid function
Define the sigmoid derivative function
Define the train function
Initialize the weights and bais
Train the model
Predict using the trained model
