🤖 AI Fundamentals
Artificial Intelligence is the simulation of human intelligence in machines, particularly through machine learning algorithms.
Neural Network Forward Pass
The computation of output from input through the network:
y = f(Wx + b)
Where W is the weight matrix, x is the input, b is the bias, and f is the activation function.
Backpropagation
The algorithm for training neural networks:
∂L/∂w = ∂L/∂y × ∂y/∂w
Where L is the loss function and w represents the weights.
Gradient Descent
The optimization algorithm for minimizing loss:
w = w - α∇L(w)
Where α is the learning rate and ∇L(w) is the gradient of the loss function.
🧠 Key Insight: Machine learning enables computers to learn patterns from data without being explicitly programmed, revolutionizing how we solve complex problems.
