LSTM is a recurrent neural network type designed to deal with the vanishing gradient problem when training artificial neural networks. LSTMs contain special memory cells that can store information for extended periods, enabling the network to remember inputs that occurred much earlier in the sequence. Therefore, these networks are particularly suitable for long-term memory tasks such as speech recognition and natural language processing. The LSTM architecture has become the most commonly used structural unit in recurrent neural networks and has contributed to breakthroughs in several fields, including computer vision, speech recognition, and natural language processing. Jürgen Schmidhuber's pioneering work with the LSTM has enabled more complex and efficient use of neural networks, paving the way for intelligent systems with better learning capabilities.

Schmidhuber's contribution to LSTM algorithm

Schmidhuber's most significant contribution to the field of artificial intelligence is the long short-term memory (LSTM) algorithm, which he co-invented with his student, Sepp Hochreiter, in 1997. The LSTM algorithm is a type of recurrent neural network (RNN) that solves the vanishing gradient problem that commonly occurs in traditional RNNs. The vanishing gradient problem happens when the gradients of the error function become infinitesimally small, making it challenging to learn long-term dependencies in sequences. LSTM solves this issue by introducing specialized gating mechanisms that allow it to selectively remember or forget information as it propagates through the network. This innovation has enabled LSTM to excel in various tasks that require model memory, such as speech recognition, video analysis, and language modeling. The impact of LSTM in modern machine learning cannot be overstated and has been adopted by many researchers and industries in the world.
