Calibration and Characterization of Low-Cost Fine Particulate Monitors and their Effect on Individual Empowerment
Event Location: GHC 8102Abstract: Air quality has long been a major health concern for citizens around the world, and increased levels of exposure to fine particulate matter (PM2.5) has been definitively linked to serious health effects such as cardiovascular disease, respiratory illness, and increased mortality. PM2.5 is one of six attainment criteria pollutants used by [...]

Improving Prosody through Analysis by Synthesis
Event Location: GHC 6501Abstract: An iterative model-based method is proposed for improving linguistic structure, segmentation, and prosodic annotations that correspond to the delivery of each utterance as regularized across the data. For each iteration, the training utterances are resynthized according to the existing symbolic annotation. Values of various features and subgraph structures are "twiddled:" each [...]
Adaptive Motion Planning
Event Location: NSH 1305Abstract: Mobile robots are increasingly being deployed in the real world in response to a heightened demand for applications such as transportation, delivery and inspection. The motion planning systems for these robots are expected to have consistent performance across the wide range of scenarios that they encounter. While state-of-the art planners can [...]
Learning optimal policies for compliant gaits and their implementation on robot hardware
Bipedal animals exhibit a diverse range of gaits and gait transitions, which can robustly travel over terrains of varying grade, roughness, and compliance. Bipedal robots should be capable of the same. Despite these clear goals, state-of-the-art humanoid robots have not yet demonstrated locomotion behaviors that are as robust or varied as those of humans and [...]
