Atmosfeska vsebnost vodne pare v stolpcu zraka PWV (angl. precipitable water vapor) je globalno izrednega pomena tako z vidika hidriloškega kroženja kot prenosa energije. Radiosonde, sončni fotometer in sprejemniki GPS (pa tudi širše GNSS) so postali temeljni instrumenti za terestrično opazovanje PV ...

In this paper, we propose a new accurate algorithm for Compressed Counting, whose sample
complexity is only O (1/v2) for v-additive Shannon entropy estimation. The constant factor
for this bound is merely about 6. In addition, we prove that our algorithm achieves an
upper bound of the Fisher informa ...

We propose a backward deletion procedure to Sparse Gaussian Process Regression (SGPR) model, which can be used to refine a number of se- quential forward selection algorithms addressed recently. Some experi- mental results demonstrate the effectiveness of our approach.

We propose ABC-Boost (Adaptive Base Class Boost) for multi-class classification and present ABC-MART, an implementation of
ABC-Boost. The original MART (Multiple Additive Regression Trees) algorithm has been popular in certain industry applications (e.g.,
Web search). For binary classification, ABC- ...

This work studies the problem of distributed classification in peer-to-peer (P2P) networks. While there has been a significant amount of work in distributed classification, most of existing algorithms are not designed for P2P networks. Indeed, as server-less and router-less systems, P2P networks imp ...

Web content analysis often has two sequential and separate steps: Web Classification to identify the target Web pages, and Web Information Extraction to extract the metadata contained in the target Web pages. This decoupled strategy is highly ineffective since the errors in Web classification will b ...

Computing two-way and multi-way set similarities is a fundamental problem. This study focuses on estimating 3-way resemblance (Jaccard similarity) using b-bit minwise hashing. While traditional minwise hashing methods store each hashed value using 64 bits, b-bit minwise hashing only stores the lowes ...

Compressed sensing (sparse signal recovery) has been a popular and important research topic in recent years. By observing that natural signals (e.g., images or network data) are often nonnegative, we propose a framework for nonnegative signal recovery using Compressed Counting (CC). CC is a techniqu ...
