Hochreiter is a German-language surname. It is borne by individuals in German-speaking regions, especially Austria and Germany. Sepp Hochreiter (born 1967) is an Austrian computer scientist and professor at the Johannes Kepler University Linz, where he has led the Institute of Bioinformatics. He is best known for co-developing the Long Short-Term Memory (LSTM) recurrent neural network with Jürgen Schmidhuber. Introduced in 1997, LSTM addresses the vanishing gradient problem in recurrent networks and enables learning of long-range dependencies in sequential data. The architecture has become foundational in fields such as speech recognition, language modeling, handwriting recognition, and time-series forecasting. In addition to LSTM, Hochreiter has contributed to research on recurrent neural networks, optimization methods for deep learning, and applications of machine learning in bioinformatics. He has published extensively and has played a central role in building AI research at his institution, collaborating with researchers worldwide.
