Applying Deep Reinforcement Learning to the HP Model for Protein Structure Prediction

1 code implementation27 Nov 2022 Kaiyuan Yang, Houjing Huang, Olafs Vandans, Adithya Murali, Fujia Tian, Roland H. C. Yap, Liang Dai

This problem has been studied in a classical abstract model, the HP model, where the protein is modeled as a sequence of H (hydrophobic) and P (polar) amino acids on a lattice.

Learning Robust Search Strategies Using a Bandit-Based Approach

no code implementations10 May 2018 Wei Xia, Roland H. C. Yap

However, choosing or designing a good search heuristic is non-trivial and is often a manual process.

Correlation Heuristics for Constraint Programming

no code implementations6 May 2018 Ruiwei Wang, Wei Xia, Roland H. C. Yap

We evaluate our correlation heuristics with well known heuristics, namely, dom/wdeg, impact-based search and activity-based search.

Stochastic Database Cracking: Towards Robust Adaptive Indexing in Main-Memory Column-Stores

1 code implementation1 Feb 2012 Felix Halim, Stratos Idreos, Panagiotis Karras, Roland H. C. Yap

Stochastic cracking also uses each query as a hint on how to reorganize data, but not blindly so; it gains resilience and avoids performance bottlenecks by deliberately applying certain arbitrary choices in its decision-making.
