Beiu, V. - 2008

In this paper the authors discuss several complexity aspects pertaining to neural networks, commonly known as the curse of dimensionality. The focus will be on: (1) size complexity and depth-size tradeoffs; (2) complexity of learning; and (3) precision and limited interconnectivity. Results have...

Experimental Results on Statistical Approaches to Page Replacement Policies

LEUNG,VITUS J.; IRANI,SANDY - 2008

previously suggested algorithms (Maximum Hitting Time and Dominating Distribution) which are based on the Markov model work well … on the trace data used in this study. Interestingly, both of these algorithms perform equally well despite the fact that … the theoretical results for these two algorithms differ dramatically. We then develop succinct characteristics of memory …

Radiation transport algorithms on trans-petaflops supercomputers of different architectures.

Christopher, Thomas Woods - 2008

We seek to understand which supercomputer architecture will be best for supercomputers at the Petaflops scale and beyond. The process we use is to predict the cost and performance of several leading architectures at various years in the future. The basis for predicting the future is an expanded...

Learning and cost reductions for generating technologies in the national energy modeling system (NEMS)

Gumerman, Etan; Marnay, Chris - 2008

This report describes how Learning-by-Doing (LBD) is implemented endogenously in the National Energy Modeling System (NEMS) for generating plants. LBD is experiential learning that correlates to a generating technology's capacity growth. The annual amount of Learning-by-Doing affects the annual...
