This thesis is devoted to the study of algorithms for early perceptual learning for an autonomous agent in the presence of feedback. In the framework of associative perceptual learning with indirect supervision, three learning techniques are examined in detail: • short-term on-line memory-based model learning; • long-term on-line distribution-based statistical estimation; • mixed onand off-line...

This is the senior thesis I worked on in University of Washington, under the supervision of Prof. Ralph Greenberg. We intended to classify the torsion-free part of the unit group of a totally complex normal extension with Galois group S3 as a Z[S3]-module. We obtained a way to recognize the module structure based on the class numbers of the field extensions. Conversely we also showed that some ...
