In this riveting episode, Machine Learning TV delves into the intricate world of long short-term memory cells (LSTMs) and the notorious vanishing gradient problem plaguing recurrent neural networks (RNNs). RNNs, with their ability to recall past information, struggle with longer sequences due to these pesky vanishing or exploding gradients. As the information traverses through the sequence, the early steps gradually lose their influence on the final output and cost function, creating a tumultuous journey for the network.
Backpropagation, the process of updating weights during training, becomes a treacherous affair in networks with numerous time steps or layers. Gradients, essential for determining how much a model can improve over time, can dwindle to such minuscule values that weight updates are rendered ineffective. Conversely, the nightmare of exploding gradients occurs when updated weights spiral out of control, destabilizing the entire network and risking numerical overflow.
To combat the vanishing gradient menace, the team proposes ingenious solutions such as weight initialization to the identity matrix, employing a ReLU activation function, and implementing gradient clipping to rein in the magnitude of gradients. Furthermore, skip connections offer a lifeline by establishing a direct pathway to earlier layers, empowering initial activations to wield more influence over the cost function. These cutting-edge techniques provide a beacon of hope in the tumultuous realm of RNNs, offering a glimpse into the transformative power of LSTMs in overcoming the challenges posed by vanishing gradients.
