Creating Characters with Believable Behaviors through Reinforcement Learning

Advances in technology are enabling video games to host larger and larger virtual environments. However, most virtual environments have manually-scripted non-player characters (NPCs) and the behaviors are usually simple and repetitive since it is time-consuming for developers to script each character individually. One approach to creating NPCs with believable behaviors is to develop learning algorithms so that NPCs can learn from their own successes or failures. This talk briefly describes Reinforcement Learning, an online learning mechanism that enables NPCs to rapidly learn reasonable behaviors and adapt to the changes in the virtual environment. A few examples including combat and trap-disarmament scenarios in a virtual environment will be described.

Characterizing spatial and chronological target selection of serial offenders

TBDUsing 31 unique crime series from two US cities, the spatial pattern that individual
criminal decision makers follow is investigated. Locations within a city vary in the likelihood for
crimes of a given type to occur, and this is accounted for by using kernel density estimation
based on all crimes of each type. Kernel density estimation is highly influenced by the bandwidth,
so an objective approach is used to select the estimate. Then, the kernel density estimate for
each type of crime is incorporated in an inhomogeneous K-function that can identify significant
spatial clustering and/or uniformity at various spatial scales for each crime series. We find that
robbery series are more likely to exhibit uniformity than burglary series, which tend to show
strong clustering. In addition, the order in which new crimes are added to a series is found to
follow an interesting pattern that does not always support the theory of offender as forager in
which criminals first cluster crimes and then gradually disperse them. Half of the robbery series
exhibit a spatial distribution that begins dispersed and develops clusters as increasingly more
events are added to the series, indicating that they often return to locations of earlier crimes
after having committed crimes elsewhere.

New Statistics 20 Lecture Open for Summer Session A

Stats 20 Discussion 2A and 2B is now enrolling students for the summer with Professor Almohalwas. If you know anyone who would like to enroll, please encourage them to do so. Remember that Stats 20 is a prerequisite for entry into the Minor and the Major and students will not be allowed to apply to either without Stats 20 -- no exceptions!

Fall 2015 enrollment for Stats 20 will go quickly on a first come first serve basis open only to MAJORS, PRE-MAJORS and MINORS for the first pass. If you are trying to pursue a Stats Minor or Major, take advantage of the summer, as we cannot guarantee enrollment in the Fall quarter for Stats 20.

If you would like to enroll in the summer and cannot do so on your own, please come talk to Eduardo Navarro or Glenda Jones in 8117 Math Sciences Building.

Two of Our Faculty Named as Fellows of the American Statistical Association

Congratulations to both Peter Bentler (Distinguished Professor) and Catherine Sugar (Associate Professor in Biostatistics) who have both been named as Fellows of the American Statistical Association (ASA). The decision to grant this honor to an ASA member is based on the member’s contribution to the field of statistics, the ASA and society at large. Only about one-third of one percent of the ASA membership receive this honor each year.
