Machine Perception Research on Methodology and Application
Peking University team work extensively in the research area of Machine perception and made major breakthrough in the visual and speech perception.1) Auditory Perception. On research emphasis of speech perception is to process speech in complex scene. Binaural processing in complex scene. Listeners can achieve significant benefit from binaural hearing when sound sources are spatially separated,...

Probe Machine and Graph Theory
Computer is conceptually a general-purpose device that is built upon a computing model, and manufactured by certain materials that can be used to implement the specific computing model. For instance, today’s electronic computer is conceptualized by Turing machine (TM) and composed of electronic components. Although the phenomenal growth of TM-based computing devices (e.g., electronic computer)...

Ultracold Atom Quantum Simulation
The concept of quantum simulations was proposed by physicist Richard Phillips Feynman in 1981, and quantum simulations become possible by manipulated ultracold atoms. In 1995, Bose-Einstein condensation was realized and degenerate fermi gas in 1999. The first BEC-BCS Crossover quantum simulation experiment was carried out in 2003 by using the Fermi Gas. In 1998, Austrian scientist Peter Zoller ...
