TOPIC MODELING USING VARIATIONS ON LATENT DIRICHLET ALLOCATION
Author: Dr. Sunil Bhutada
Publisher: Ashok Yakkaldevi
ISBN: 1716688450
Category : Art
Languages : en
Pages : 102
Book Description
Till date, internet has amassed an enormous number of computerized data including news, sites, website pages, eBooks, pictures, sound, video, person to person communication and different types of information, and the number is developing exponentially. Accordingly, how individuals are arranging and managing extensive data efficiently and acquiring the essential valuable information rapidly is a massive challenge. In this manner, it is important to introduce and built automatic tools which should transform huge data into valuable, knowledgeable and useful information intelligently.

Uncertainty in Artificial Intelligence

Publisher: North Holland
ISBN: 9780444700582
Category : Artificial intelligence
Languages : en
Pages : 509
Book Description
Hardbound. How to deal with uncertainty is a subject of much controversy in Artificial Intelligence. This volume brings together a wide range of perspectives on uncertainty, many of the contributors being the principal proponents in the controversy.Some of the notable issues which emerge from these papers revolve around an interval-based calculus of uncertainty, the Dempster-Shafer Theory, and probability as the best numeric model for uncertainty. There remain strong dissenting opinions not only about probability but even about the utility of any numeric method in this context.

Constrained Clustering
Author: Sugato Basu
Publisher: CRC Press
ISBN: 9781584889977
Category : Computers
Languages : en
Pages : 472
Book Description
Since the initial work on constrained clustering, there have been numerous advances in methods, applications, and our understanding of the theoretical properties of constraints and constrained clustering algorithms. Bringing these developments together, Constrained Clustering: Advances in Algorithms, Theory, and Applications presents an extensive collection of the latest innovations in clustering data analysis methods that use background knowledge encoded as constraints. Algorithms The first five chapters of this volume investigate advances in the use of instance-level, pairwise constraints for partitional and hierarchical clustering. The book then explores other types of constraints for clustering, including cluster size balancing, minimum cluster size,and cluster-level relational constraints. Theory It also describes variations of the traditional clustering under constraints problem as well as approximation algorithms with helpful performance guarantees. Applications The book ends by applying clustering with constraints to relational data, privacy-preserving data publishing, and video surveillance data. It discusses an interactive visual clustering approach, a distance metric learning approach, existential constraints, and automatically generated constraints. With contributions from industrial researchers and leading academic experts who pioneered the field, this volume delivers thorough coverage of the capabilities and limitations of constrained clustering methods as well as introduces new types of constraints and clustering algorithms.
