    Week 1-2: Module 1 – Foundations of Neural Networks

    \Lesson 1: Introduction to Artificial Intelligence, Machine Learning, and Deep Learning\ \ \\Learning Objectives:\
    \ \Differentiate between AI, ML, and DL and understand their hierarchical relationship.\ \Appreciate the historical context and recent resurgence of deep learning.\ \Identify common applications of deep learning in today’s world.\ \ \
    \\Key Vocabulary:\
    \ \\Artificial Intelligence (AI):\ The theory and development of computer systems able to perform tasks that normally require human intelligence.\ \\Machine Learning (ML):\ A subset of AI that enables systems to learn from data without explicit programming.\ \\Deep Learning (DL):\ A subset of ML that uses neural networks with many layers (deep neural networks).\ \\Supervised Learning:\ Learning from labeled data (input-output pairs).\ \\Unsupervised Learning:\ Learning from unlabeled data to find patterns.\ \\Reinforcement Learning:\ Learning through trial and error with rewards and penalties.\ \ \
    \\Content:\
    \We begin our journey by setting the stage. Artificial Intelligence is the broad field of creating intelligent machines. Machine Learning is a branch of AI where systems learn from data. Deep Learning, in turn, is a specialized branch of Machine Learning that uses deep neural networks, inspired by the human brain’s structure. Think of AI as the entire universe of intelligent systems, ML as a galaxy within it, and DL as a specific solar system. The resurgence of deep learning is attributed to advancements in computational power (GPUs), vast amounts of data, and improved algorithms. Deep learning powers facial recognition, self-driving cars, voice assistants, and medical diagnosis.\ \

    \Lesson 2: The Perceptron and Basic Neural Network Structure\ \ \\Learning Objectives:\
    \ \Understand the concept of a perceptron as the building block of neural networks.\ \Explain the role of activation functions.\ \Describe the basic architecture of a feedforward neural network (input, hidden, output layers).\ \ \
    \\Key Vocabulary:\
    \ \\Perceptron:\ The simplest form of a neural network, a single artificial neuron.\ \\Neuron (Node):\ A computational unit in a neural network.\ \\Input Layer:\ The first layer that receives the raw input data.\ \\Hidden Layer:\ Layers between the input and output layers where most computation occurs.\ \\Output Layer:\ The final layer that produces the network’s prediction.\ \\Weight:\ A parameter that determines the strength of the connection between two neurons.\ \\Bias:\ A parameter that shifts the activation function’s output.\ \\Activation Function:\ A non-linear function applied to the output of a neuron, introducing non-linearity.\ \ \
    \\Content:\
    \The perceptron, proposed by Frank Rosenblatt in 1957, is the fundamental unit of a neural network. It takes multiple inputs, multiplies them by weights, sums them up, adds a bias, and then passes the result through an activation function to produce an output. Imagine a switch that turns on only if enough “signals” (weighted inputs) are strong enough. Without activation functions, a deep neural network would simply be a series of linear transformations, incapable of learning complex patterns. Common activation functions include ReLU, Sigmoid, and Tanh. A feedforward neural network consists of an input layer, one or more hidden layers, and an output layer. Information flows only in one direction, from input to output.\ \
    \\Practical Hands-on Example:\
    \ \\Task:\ Implement a simple perceptron from scratch in Python.\ \\Instructions:\
    \ \Define a function for the step activation function.\ \Create a perceptron function that takes inputs, weights, and a bias.\ \Test the perceptron with a simple AND gate logic.\ \ \

    \Lesson 3: Training a Neural Network: Loss Functions and Optimization\ \ \\Learning Objectives:\
    \ \Understand the concept of a loss function and its importance in training.\ \Explain the purpose of optimization algorithms (e.g., Gradient Descent).\ \Describe the backpropagation algorithm for updating weights and biases.\ \ \
    \\Key Vocabulary:\
    \ \\Loss Function (Cost Function):\ A function that quantifies the difference between the predicted output and the true output.\ \\Optimization:\ The process of minimizing the loss function.\ \\Gradient Descent:\ An iterative optimization algorithm used to find the minimum of a function by moving in the direction of the steepest descent.\ \\Learning Rate:\ A hyperparameter that controls the step size in gradient descent.\ \\Backpropagation:\ An algorithm used to efficiently calculate the gradients of the loss function with respect to the weights and biases.\ \ \
    \\Content:\
    \Training a neural network is about finding the optimal set of weights and biases that minimize the error between its predictions and the actual values. This error is measured by a “loss function.” For example, Mean Squared Error (MSE) is common for regression tasks, while Cross-Entropy is used for classification. The goal of “optimization” is to minimize this loss. Gradient Descent is the workhorse here: it iteratively adjusts the weights and biases by moving in the direction opposite to the gradient of the loss function. The “learning rate” determines how big these steps are. Too large, and you overshoot; too small, and training is slow. “Backpropagation” is the clever algorithm that makes this process computationally feasible by efficiently calculating the gradients from the output layer back to the input layer.\ \
    \\Practical Hands-on Example:\
    \ \\Task:\ Implement a simple feedforward neural network and train it using gradient
