Distributed Search Using A Logistic Regression Model
نویسنده
چکیده
This short paper presents some preliminary effectiveness results for a probabilistic approach to distributed information retrieval using a Logistic regression algorithm for estimation of collection relevance. The algorithm is compared to other methods for distributed search using test collections developed for distributed search evaluation.

The operation of a distribution system in the presence of distributed generation systems has someadvantages and challenges. Optimal sizing and siting of DG systems has economic, technical, andenvironmental benefits in distribution systems. Improper selection of DG systems can reduce theseadvantages or even result in deterioration in the normal operation of the distribution system. DGallocation ...

However, in predicting the rate of return, in addition to the modeling method, the degree of co...
متن کاملHow to use SAS® to fit Multiple Logistic Regression Models
When response outcomes are continuous error terms in models are normally distributed and a standard normal distribution function is adequate. The logistic distribution function which is very similar to the normal distribution function is required when the response variable is binary. Parameters of a logistic response function are often estimated using the method of maximum likelihood (ML). One ...
