Sepp Hochreiter, the inventor of LSTM, has unveiled a new LLM architecture called xLSTM, which stands for Extended Long Short-Term Memory.xLSTM addresses the weaknesses of previous LSTM designs, such as sequential processing, limited storage capacities, and lack of parallelizability.The main components of xLSTM include matrix memory for LSTM, eliminating memory mixing, and exponential gating.xLSTM architecture performs favorably compared to Transformers and has the potential to impact various deep learning fields.
