LSH At Large - Distributed KNN Search in High Dimensions

Karl Aberer, Sebastian Michel, Parisa Haghani

We consider K-Nearest Neighbor search for high dimensional data in large-scale structured Peer-to-Peer networks. We present an efficient mapping scheme based on p-stable Locality Sensitive Hashing to assign hash buckets to peers in a Chord-style overlay ne ...

Virtual Reality Based Simulation of Hysteroscopic Interventions

Gábor Székely

Virtual reality based simulation is an appealing option to supplement traditional clinical education. However, the formal integration of training simulators into the medical curriculum is still lacking. Especially, the lack of a reasonable level of realism ...

An intuitive daylighting performance analysis and optimization approach

Marilyne Andersen, Magali Bodart

The effective integration of daylighting considerations into the design process requires many issues to be considered simultaneously, such as daily and seasonal variations, illumination, and thermal comfort. To address the need for early integration into t ...

Compressive Sensing For Sensor Calibration

Volkan Cevher

We consider a calibration problem, where we determine an unknown sensor location using the known track of a calibration target and a known reference sensor location. We cast the calibration problem as a sparse approximation problem where the unknown sensor ...

Combining Evidence from a Generative and a Discriminative Model in Phoneme Recognition

Hynek Hermansky, Joel Praveen Pinto

We investigate the use of the log-likelihood of the features obtained from a generative Gaussian mixture model, and the posterior probability of phonemes from a discriminative multilayered perceptron in multi-stream combination for recognition of phonemes. ...

Dynamic faceted search for discovery-driven analysis

Anastasia Ailamaki, Debabrata Dash

We propose a dynamic faceted search system for discovery-driven analysis on data with both textual content and structured attributes. From a keyword query, we want to dynamically select a small set of "interesting" attributes and present aggregates on them ...

A modular simulation framework for colonoscopy using a new haptic device

Hannes Bleuler, Evren Samur

We have developed a multi-threaded framework for colonoscopy simulation utilising OpenGL with an interface to a real-time prototype colonoscopy haptic device. A modular framework has enabled us to support multiple haptic devices and efficiently integrate n ...

Flexible simulators for OBS network architectures

Sébastien Rumley, Christian Gaumier

Since the OBS paradigm has become a potential candidate to cope with the needs of the future all optical networks, it has really caught the attention from both academia and industry worldwide. In this direction, OBS networks have been investigated under ma ...
