Scalable algorithms for high-dimensional graphical lasso and function approximation

Eftekhari, Aryan ; Schenk, Olaf (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO008.

Fundamental tasks in multivariate and numerical analysis, such as sparse precision matrix estimation via graphical lasso and function approximation, are formulated in ever-increasing dimensions. Consequently, this results in a significant increase in the computational demand that quickly renders standard solution methods intractable. With this motivation, we present two scalable algorithms that...

Opinion mining for software development

Lin, Bin ; Bavota, Gabriele (Dir.) ; Lanza, Michele (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO010.

Opinion mining, which uses computational methods to extract opinions and sentiments from natural language texts, can be applied to various software engineering (SE) tasks. For example, developers can mine user feedback from mobile app reviews to understand how to improve their products, and software team leaders can assess developers' mood and emotions by mining communication logs or commit...
