We propose an online topic model for sequentially analyzing the time evolution of topics in document collections. Topics naturally evolve with multiple timescales. For example, so...
Abstract. Conceptual models are formal descriptions of application domains that are used in early stages of system development to support requirements analysis. The Unified Modeli...
Abstract--To achieve a high product quality for nano-scale systems both realistic defect mechanisms and process variations must be taken into account. While existing approaches for...
Abstract. We survey recent developments in an approach to the verification of higher-order computation based on game semantics. Higherorder recursion schemes are in essence (progra...
A navigation model describes the possible sequences of web pages a user can visit, and a request routing model describes how server side components handle each request. Earlier we...
