Introduction to Vanishing Gradient and LSTM
The vanishing gradient problem occurs when the contribution of earlier inputs diminishes to almost zero as one processes through a sequence in machine learning models. This issue arises predominantly in recurrent neural networks, which struggle to retain information from previous states due to gradients becoming too small. Sepp Hochreiter highlighted that despite the need for a consistent contribution regardless of the input's position in a sequence, traditional architectures fail to achieve this. His groundbreaking work led to the development of Long Short-Term Memory (LSTM) networks, which successfully maintain consistent importance over time, addressing the inherent limitations of previous neural networks.
