Yann LeCun Computer scientist

Yann LeCun’s research interests include computational and biological models of learning and perception. One of his goals is to understand the principles of learning in the brain, and to build computational models with similar learning abilities. His research is primarily applied to artificial vision, allowing computers to recognize objects in images, and mobile robots to navigate using vision. He also applies his large-scale learning algorithms to other domains, such as predicting epilepsy seizures from EEG signal, predicting data with spatio-temporal dependencies such as real estate prices, and identifying sub-cellular structures in biological images.

In past decades, LeCun worked on document understanding and OCR, as well as on data compression and digital libraries. His image compression technology, called DjVu, is used by numerous digital libraries and publishers, including the Internet Archive and the New Yorker to distribute scanned documents on-line or on DVD. His handwriting recognition technology, which uses a biologially inspired learning system, has been used commercially since the mid-90s in bank cheque-reading machines. It automatically processes a large percentage of bank cheques in the US. His learning-based image understanding techniques are used in many industrial applications, including video surveillance, document understanding, and human-computer interaction.
