THE FUTURE IS HERE

Intro to Python Deep Learning libraries- Tensorflow, Keras, PyTorch | Programming foundations for ML

Welcome to this foundational lecture on deep learning frameworks in Python – TensorFlow, Keras, and PyTorch. If you are new to machine learning or just getting started with deep learning, this video will give you a comprehensive overview of how to build and train neural networks using the most popular Python libraries.

In this hands-on tutorial, you will learn:

What is a neural network and why it is called a universal function approximator

The role of activation functions like ReLU and Sigmoid

The difference between shallow and deep neural networks

When to use deep learning vs traditional machine learning

How to build a simple binary classification model using Keras with TensorFlow backend

How to build the same model from scratch using PyTorch

The pros and cons of Keras, TensorFlow, and PyTorch

Why GPU acceleration matters in deep learning

How to visualize your training progress with accuracy and loss curves

You will also see a live coding demo in Google Colab where we:

Generate a synthetic dataset using make_classification from Scikit-learn

Scale the dataset using StandardScaler

Train a simple deep neural network in Keras and then in PyTorch

Visualize model performance with Matplotlib

Compare training and test accuracy across frameworks

Whether you are trying to understand which framework is right for your project, or you simply want to get comfortable writing your first deep learning models, this video will provide a structured and intuitive learning experience.
