We propose new hierarchical models and estimation techniques to solve the problem of heteroscedasticity in Bayesian optimisation. Our results demonstrate substantial gains in a wide range of applications, including automatic machine learning and mining exploration .
Data-efficient reinforcement learning (RL) in continuous state-action spaces using very high-dimensional observations remains a key challenge in developing fully autonomous systems. We consider a particularly important instance of this challenge , the pixels-to-torques problem, where an RL agent learns a closed-loop control policy (" torques ") from pixel… (More)
Multiple matching algorithms are used to locate the occurrences of patterns from a finite pattern set in a large input string. Aho-Corasick and Wu-Manber, two of the most well known algorithms for multiple matching require an increased computing power, particularly in cases where large-size datasets must be processed, as is common in computational biology… (More)
