Understanding and improving GPUs’ reliability combining beam experiments with fault simulation
(2021) [Tese]Graphics Processing Units (GPUs) have moved from being dedicated devices for multi media and gaming applications to general-purpose accelerators, employed in High Perfor mance Computing (HPC) and safety-critical applications, ... -
Understanding and recovering architecture rules
(2021) [Tese]Software architecture is fundamental to clearly present the most important structures, roles, and rules of a software, which collectively are used to guide software design and implementation. Thus, the existence of reliable ... -
Understanding sample generation strategies for learning heuristic functions in classical planning
(2023) [Dissertação]Heuristic functions are essential in guiding search algorithms to solve planning tasks. We study the problem of learning good heuristic functions for classical planning tasks with neural networks based on samples that are ... -
Understanding stance classification of BERT models : an attention-based mechanism
(2022) [Dissertação]BERT produces state-of-the-art solutions for many natural language processing tasks at the cost of interpretability. As works discuss the value of BERT’s attention weights to this purpose, we contribute with an attention-based ... -
Understanding the impact of teams in modern code review
(2021) [Dissertação]Modern code review (MCR) is a practice in which code reviews are performed in a tool supported, asynchronous, and lightweight way and is widely adopted in the software in dustry. MCR provides improved code quality and fewer ... -
