UIC AI Lab Technical Report Series:

• UIC-AIL-TR01.ps - Computational modeling of biological motifs using local search based alignment techniques; specific application to transcription factor modeling. Software is available.

• UIC-AIL-TR02.ps - Biological tree motifs. Probabilistic trees are investigated for their ability to model biological motifs. Software is available.

• UIC-AIL-TR03.ps - An Application of Bagging for Reducing Run-Time Complexity. Problems which use algorithms of high complexity and have large amounts of data suffer from excessive run-times. Frequently, such problems may be un-computable all together. This paper describes a novel application of bagging which allows one to solve such problems in a greatly reduced amount of time while retaining an accurate (and frequently better) solution. Software is available.

• UIC-AIL-TR04.ps - Ensembles of Latent Semantic Classifiers. Bagging is a popular ensemble learning method which has its roots in statistics. Its application for solving complex problems with large data sizes is described in UIC-AIL-TR03. Here, that method is applied to training latent semantic classifiers to achieve tremendous savings in run-time and memory usage. Software is available.

• UIC-AIL-TR05.ps - A Framework for Sequential Planning in Multiagent Settings. A novel framework for optimal sequential decision-making in multiagents settings is introduced. Properties, and preliminary results using the multiagent tiger game are also presented in the report.
