Neural Networks

A paradigm inspired by the human brain. Discover how computer models learn to think, classify, and understand language just like sorting toys in a giant box.

The Brain & The Toy Box

Imagine your brain with billions of neurons working together. Scientists built computer models called "Neural Networks" to mimic this.

The Toy Box Analogy

Imagine a giant box of toys: cars, dolls, blocks. To sort them, you pick each one up and decide its category. Neural networks do the same with text—sorting books, tweets, and articles into categories like "Sports" or "Science" (Document Classification) or deciding if a review is happy or sad (Sentiment Analysis).

Structure

Anatomy of a Neural Network

Like a line of dominoes, neurons are organized into layers. The data flows, math happens, and a decision emerges.

Input Layer

Receives raw data, like the text from a book. The "First Domino" in the chain.

The Brains

Hidden Layers

Layers in the middle that help with decision making. They do the math (add, multiply).

Process: Backpropagation & Gradient Descent adjust these neurons to "straighten the tower" of learning.

Output Layer

Makes the final decision. "Is it a Mystery or Romance novel?" The final domino falls.

The Magician's Theater

The magician displays three mystical boxes to turn words into stories. Which box will you open?

The Magical Tunnel

Feedforward NN

Words enter and embark on a one-way journey. Like an alchemist, it refines the input step-by-step until a story type emerges at the exit. Straightforward and effective.

The Detective

CNN

Uses a "magical magnifying lens" to zoom into sequences and find patterns like "Once upon a time." It detects underlying narrative styles through clues, just like looking at an image.

The Box with Memory

RNN

An intricate network of loops acting as memory vessels. It remembers past information to understand the present context. Like telling a story to a friend who remembers every detail.
