Testing is the main approach used in the software industry to expose failures. Producing thorough test suites is an expensive and error prone task that can greatly benefit from automation.

By the end of the 1970s, it became evident that hierarchies were not always the most efficient and effective solution for complex problems in increasingly plural and fragmented societies. During the last 40 years governance structures and practices in the public sector have shifted towards new logics that direct the way the public sector is functioning. This dissertation deals with use of ...

Nonetheless, we know little about the factors that facilitate unethical consumption. This article uses the experimental method to investigate the unethical consumption in the gifting experience context and the impact of psychological...

Data-based analysis of extreme events : inference, numerics and applications

Kaiser, Olga ; Horenko, Illia (Dir.)

Slowness learning for curiosity-driven agents

Kompella, Varun Raj ; Schmidhuber, Jürgen (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2014 ; 2014INFO013.

In the absence of external guidance, how can a robot learn to map the many raw pixels of high-dimensional visual inputs to useful action sequences? I study methods that achieve this by making robots self-motivated (curious) to continually build compact representations of sensory inputs that encode different aspects of the changing environment. Previous curiosity-based agents acquired skills by...
