Deep Learning

ELI5 — The Vibe Check

Deep Learning is Machine Learning that's been hitting the gym. Instead of simple models, it uses massive neural networks with many layers — like an onion of math. Each layer learns something slightly more abstract, until the last layer can tell you 'this is a hot dog' with alarming confidence.

Real Talk

Deep Learning uses artificial neural networks with multiple hidden layers to learn hierarchical representations of data. It excels at tasks like image recognition, speech processing, and natural language understanding. The 'deep' refers to the depth of these layer stacks, which can number in the hundreds for modern architectures.

Show Me The Code

import torch.nn as nn
model = nn.Sequential(
    nn.Linear(784, 256),
    nn.ReLU(),
    nn.Linear(256, 128),
    nn.ReLU(),
    nn.Linear(128, 10)
)
