Deep Learning

Loss functions are the backbone of every neural network — they tell the model how wrong it is and how to improve. This guide breaks down key loss functions like MSE, MAE, Huber, Binary Cross-Entropy, and Categorical Cross-Entropy — with formulas, intuition, and use cases. Understand how loss drives learning through forward and backward propagation and why choosing the right one is crucial for better model performance.

The Multi-Layer Perceptron (MLP) is the foundation of modern neural networks — the model that gave rise to deep learning itself. In this complete guide, we break down the architecture, intuition, and mathematics behind MLPs. You’ll learn how multiple perceptrons, when stacked in layers with activation functions, can model complex non-linear relationships and make intelligent predictions.
