Safe Exploration for Optimizing Contextual Bandits [PDF]
ACM Transactions on Information Systems, 2020 Contextual bandit problems are a natural fit for many information retrieval tasks, such as learning to rank, text classification, recommendation, and so on. However, existing learning methods for contextual bandit problems have one of two drawbacks: They either do not explore the space of all possible document rankings (i.e., actions) and, thus, may ...

Safe Visual Data Exploration [PDF]
Proceedings of the 2017 ACM International Conference on Management of Data, 2017 Exploring data via visualization has become a popular way to understand complex data. Features or patterns in visualization can be perceived as relevant insights by users, even though they may actually arise from random noise. Moreover, interactive data exploration and visualization recommendation tools can examine a large number of observations, and ...

Reinforcement Learning by Guided Safe Exploration [PDF]
, 2023 Safety is critical to broadening the application of reinforcement learning (RL). Often, we train RL agents in a controlled environment, such as a laboratory, before deploying them in the real world. However, the real-world target task might be unknown prior to deployment.

Study on the Rheology of CO2 Hydrate Slurry by Using the Capillary Method
Journal of Marine Science and Engineering, 2022 The rheological properties of the CO2 hydrate slurry are experimentally investigated by using a new flow loop with an inner diameter of 50 mm. The pressure drops of the CO2 hydrate slurry are measured experimentally under the volumetric hydrate fraction,

Guiding Safe Exploration with Weakest Preconditions
CoRR, 2022 In reinforcement learning for safety-critical settings, it is often desirable for the agent to obey safety constraints at all points in time, including during training. We present a novel neurosymbolic approach called SPICE to solve this safe exploration problem.

GC×GC-TOFMS analysis of ethanodiamondoids in Ordovician oil from well SN1, Tarim Basin
Shiyou shiyan dizhi, 2023 By 2D gas chromatography and time-of-flight mass spectrometry (GC×GC-TOFMS), 81 ethanodiamondoids with 1-3 cages were detected quantitatively in Ordovician crude oil from well SN1, Shuntuoguole area, Tarim Basin, including 47 ethanoadamantanes with total

Benefits of Monotonicity in Safe Exploration with Gaussian Processes
CoRR, 2022 We consider the problem of sequentially maximising an unknown function over a set of actions while ensuring that every sampled point has a function value below a given safety threshold. We model the function using kernel-based and Gaussian process methods, while differing from previous works in our assumption that the function is monotonically ...
