intelligent inference systems corp., sunnyvale, ca research scientist
april 2002 – april 2003: started a new research initiative in applying the acfrl algorithm and the previously developed multi-agent coordination algorithms to power control in wireless networks. published several conference papers on this topic. results demonstrate an improvement by more than a factor of 2 in comparison with the algorithms used in is-95 and cdma2000 standards.
april 2002 – april 2003: wrote a phase i sttr proposal to the office of naval research and received funding for the topic of “perception-based co-evolutionary reinforcement learning for uav sensor allocation.” developed theoretical algorithms and designed a practical implementation strategy, which demonstrated excellent results in a high-fidelity robotic simulator. published a conference paper.
october 1998 – april 2002: wrote a proposal to the nasa program in thinking systems and received multi-year funding for the topic of cooperation and coordination in multi-agent systems. developed, ｅｖａｌuated, and published new reinforcement learning algorithms for dynamic resource allocation among distributed agents operating jointly in complex, uncertain, and nonstationary environments.
fall 2000: developed a new algorithm for single-agent learning in noisy dynamic environments with delayed rewards: actor-critic fuzzy reinforcement learning (acfrl). published a conference and a journal paper with a convergence proof for acfrl. us patent (number 6,917,925) was granted for the acfrl algorithm on july 12, 2005.
