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.

New Binary Black Hole Mergers in the Second Observing Run of Advanced LIGO and Advanced Virgo

1 code implementation15 Apr 2019 Tejaswi Venumadhav, Barak Zackay, Javier Roulet, Liang Dai, Matias Zaldarriaga

The most secure new event, GW170121 ($p_{\rm astro} > 0. 99$), is also notable due to its inferred negative value of $\chi_{\rm eff}$, which is inconsistent with being positive at the $\approx 95. 8\%$ confidence level.

Heating of the intergalactic medium by the cosmic microwave background during cosmic dawn

1 code implementation6 Apr 2018 Tejaswi Venumadhav, Liang Dai, Alexander Kaurov, Matias Zaldarriaga

We also find that the effect is more dramatic in non-standard scenarios that either enhance the radio background above the CMB or invoke new physics to cool the gas in order to explain the EDGES results.

Sequential Monte Carlo Methods for System Identification

no code implementations20 Mar 2015 Thomas B. Schön, Fredrik Lindsten, Johan Dahlin, Johan Wågberg, Christian A. Naesseth, Andreas Svensson, Liang Dai

One of the key challenges in identifying nonlinear and possibly non-Gaussian state space models (SSMs) is the intractability of estimating the system state.

Sparse Estimation From Noisy Observations of an Overdetermined Linear System

no code implementations12 Feb 2014 Liang Dai, Kristiaan Pelckmans

This note studies a method for the efficient estimation of a finite number of unknown parameters from linear equations, which are perturbed by Gaussian noise.
