    Feedforward Neural Networks (FNNs)

    In this new episode we explore Feedforward Neural Networks (FNNs), the simplest form of artificial neural networks. We explore how data flows in one direction, passing through input, hidden, and output layers. Learn about the two key phases: forward propagation where weighted inputs are combined and activated, and prediction, where outputs become continuous values or probabilities. FNNs are versatile, useful for classification and regression tasks, but they struggle with sequential data, need good feature engineering, have difficulty with high-dimensional inputs, are prone to overfitting, and can be inefficient in large networks. Tune in to understand the foundations of machine learning.

    Training Neural Networks

    Ever wondered how neural networks learn? In this episode, we dive deep into the training process. First, the forward pass calculates the network's output. Then, backpropagation uses the chain rule to compute the gradients of a loss function, like MSE or cross-entropy. We explore how these gradients help to update parameters, driving the network towards optimal accuracy. We'll also discuss key optimization algorithms, such as Stochastic Gradient Descent (SGD) and Adam, which adjust these parameters to minimize loss. Join us as we unravel the magic behind network learning and reveal how choosing the right loss function and optimizer is key.
