EXMOTIF: efficient structured motif extraction [PDF]
Extracting motifs from sequences is a mainstay of bioinformatics. We look at the problem of mining structured motifs, which allow variable length gaps between simple motif components. We propose an efficient algorithm, called EXMOTIF, that given some sequence(s), and a structured motif template, extracts all frequent structured motifs that have quorum ...

An efficient algorithm for information decomposition and extraction [PDF]
The Hirschfeld-Gebelein-Renyi maximal correlation is a well-known measure of statistical dependence between two (possibly categorical) random variables. In inference problems, the maximal correlation functions can be viewed as so called features of observed data that carry the largest amount of information about some latent variables.

Thermodynamic Analysis of a Steam Power Plant with Double Reheat and Feed Water Heaters
A steam cycle with double reheat and turbine extraction is presented. Six heaters are used, three of them at high pressure and the other three at low pressure with deaerator. The first and second law analysis for the cycle and optimization of the thermal

Dependency Parsing with Efficient Feature Extraction [PDF]
The fastest parsers currently can parse an average sentence in up to 2.5ms, a considerable improvement, since most of the older accuracy-oriented parsers parse only few sentences per second. It is generally accepted that the complexity of a parsing algorithm is decisive for the performance of a parser. However, we show that the most time consuming part
