The D* algorithm computes efficient symbolic derivatives for these functions by symbolically executing the expression graph at compile time to eliminate common subexpressions and by exploiting the special nature of the graph that represents the derivative of a function.

The download includes the D* executable and full source code for the following: basic D* programming examples, Lagrangian dynamics, and a basic interactive geometric modeling tool. This is unsupported code but if you find bugs or have feature requests send…

An algorithm which breaks the problem into two pieces: predicting future demand and determining power state transitions to minimize power while meeting demand in the best way.

Derivatives arise frequently in graphics applications. To meet this need we have added symbolic differentiation as a built-in language feature in the HLSL shading language.

We present an algorithm that uses a point spread function (PSF) measurement at a single depth to calibrate the nominal lens model to the measured PSF. The fitted model can then be used to compute the PSF for any desired…

The goals of this project are to develop a neural network language that is easy to use and understand, can be compiled to very efficient code, allows derivatives of any order, and makes it easy for the end user to…

2011-2015 Face to face or remote conversations can sometimes be challenging, be it for the language barriers or because of lack of topics that may keep a conversation smoothly flowing. We look at technology solutions to help enhance conversations across…

Project WITTY exploits multi-sensory information to improve user experience in speech-centric human computer interaction and computer-mediated human inter-communication.

Current interactive surfaces provide little or no in-formation about which fingers are touching the surface, the amount of pressure exerted, or gestures that occur when not in contact with the surface. These limitations constrain the interaction vocabulary available to interactive…
