Fashion-MNIST is a dataset created by Zalando Research as a drop-in replacement for MNIST. It consists of 70,000 grayscale images (28×28 pixels) categorized into 10 different classes of clothing, such as shirts, sneakers, and coats. Your mission? Train a model to classify these fashion items correctly!

Gradient descent is fundamental method in training a deep learning network. It aims to minimize the loss function
Training Failure: SGD can't classify the spiral pattern
The Perceptron, created by Frank Rosenblatt in the 1950s, was one of the first neural networks designed to classify patterns. Initially celebrated, it became a foundational milestone in machine learning.

The human brain remains one of the greatest mysteries, far more complex than anything else we know. It is the most complicated object in the universe that we know of. The underlying processes and the source of consciousness, as well as consciousness itself, remain unknown. Neural Nets are good for popularizing Deep Learning algorithms, but we can't say for sure what mechanism behind biological Neural Networks enables intelligence to arise.

Weight initialization is crucial in training neural networks, as it sets the starting point for optimization algorithms. The activation function applies a non-linear transformation in our network. Different activation functions serve different purposes. Choosing the right weight initialization and activation function is key to better neural network performance. Xavier initialization is ideal for Sigmoid or Tanh in feedforward networks. He initialization pairs well with ReLU for faster convergence, especially in CNNs. Matching these improves training efficiency and model performance.
