Symbolic mathematics system evaluators (extended abstract)

Richard J. Fateman
1996 Proceedings of the 1996 international symposium on Symbolic and algebraic computation - ISSAC '96  
Evaluation" of expressions and programs in a computer algebra system is central to every system, but inevitably fails to provide complete satisfaction.  ...  In traversing the tree downward, the first phase of evaluation imposes the constraint that the types of its arguments must (at least) be objects that can be added.  ...  In spite of the plethora of eval-programs, a serious programmer would be well advised to learn of yet additional commands with "evaluation-like" features in Maple.  ...

Variable Elimination in Binary CSPs (Extended Abstract)

Martin C. Cooper, Achref El Mouelhi, Cyril Terrioux
2020 Proceedings of the Twenty-Ninth International Joint Conference on Artificial Intelligence  
Using our variable-elimination rules in preprocessing allowed us to solve more benchmark problems than without.  ...  We investigate rules which allow variable elimination in binary CSP (constraint satisfaction problem) instances while conserving satisfiability.  ...  It was recently shown that an agent's best response can be computed in polynomial time for any bounded number of agents using dynamic programming [Xiao and Ling, 2020] .  ...

Lowering the barrier to applying machine learning

Kayur Patel
2010 Proceedings of the 28th of the international conference extended abstracts on Human factors in computing systems - CHI EA '10  
I examine how data affects the way we program. Specifically, this dissertation focuses on using machine learning algorithms to train a model.  ...  Lowering the Barrier to Applying Machine Learning Data is driving the future of computation: analysis, visualization, and learning algorithms power systems that help us diagnose cancer, live sustainably  ...  The constraint would assert that for all future experiments, the accuracy of Naïve Bayes and decision trees should be lower than support vector machines.  ...

Exploring iterative and parallel human computation processes

Greg Little
2010 Proceedings of the 28th of the international conference extended abstracts on Human factors in computing systems - CHI EA '10  
Decision Tasks If we have two descriptions for the same image, we can use a decision task to let the process know which is best. Decision tasks solicit opinions about existing content.  ...  The goal of a decision task is to solicit an accurate response. Toward this end, decision tasks may ask for multiple responses, and use the aggregate.  ...

Improving user interaction with spoken dialog systems via shaping

Stefanie Tomko
2005 CHI '05 extended abstracts on Human factors in computing systems - CHI '05  
One problem is that users often speak beyond the bounds of what the computer is programmed to understand.  ...  However, many factors conspire to make user communication with such a system less than optimally efficient.  ...  When a back-off to the SLM was triggered, a decision tree was used to classify the utterance as to what user was most likely trying to do.  ...
