This paper describes using wearable computing devices to perform "sousveillance" (inverse surveillance) as a counter to organizational surveillance. A variety of wearable computing devices generated different kinds of responses, and allowed for the collection of data in different situations. Visible sousveillance often evoked counter-performances by(More)
Real-world planning problems often feature multiple sources of uncertainty , including randomness in outcomes, the presence of adversarial agents, and lack of complete knowledge of the world state. This thesis describes algorithms for four related formal models that can address multiple types of uncertainty: Markov decision processes, MDPs with adversarial(More)
This set of notes presents the Support Vector Machine (SVM) learning algorithm. SVMs are among the best (and many believe are indeed the best) " off-the-shelf " supervised learning algorithm. To tell the SVM story, we'll need to first talk about margins and the idea of separating data with a large " gap. " Next, we'll talk about the optimal margin(More)
We describe a soft-x-ray laser interferometry technique that allows two-dimensional diagnosis of plasma electron density with picosecond time resolution. It consists of the combination of a robust high-throughput amplitude-division interferometer and a 14.7-nm transient-inversion soft-x-ray laser that produces approximately 5-ps pulses. Because of its(More)
When documents are organized in a large number of topic categories , the categories are often arranged in a hierarchy. The U.S. patent database and Yahoo are two examples. This paper shows that the accuracy of a naive Bayes text classiier can be signiicantly improved by taking advantage of a hierarchy of classes. We adopt an established statistical(More)
— One of the fundamental challenges in implementing complex biocircuits is understanding how the spatial arrangement of biological parts impacts biocircuit behavior. We develop a set of synthetic biology parts for systematically probing the effects of spatial arrangement on levels of transcription. Our initial experimental assays prove that even the(More)
Spectrally resolved scattering of ultrafast K-alpha x-rays has provided experimental validation of the modeling of the compression and heating of shocked matter. The elastic scattering component has characterized the evolution and coalescence of two shocks launched by a nanosecond laser pulse into lithium hydride with an unprecedented temporal resolution of(More)
