Neural Networks Learn Statistics of Increasing Complexity

1 code implementation6 Feb 2024 Nora Belrose, Quintin Pope, Lucia Quirke, Alex Mallen, Xiaoli Fern

The distributional simplicity bias (DSB) posits that neural networks learn low-order moments of the data distribution first, before moving on to higher-order correlations.

Non-equilibrium molecular geometries in graph neural networks

no code implementations7 Mar 2022 Ali Raza, E. Adrian Henle, Xiaoli Fern

Moreover, many of the properties that we aim to predict can often be obtained with little or no overhead on top of the DFT calculations used to produce the 3D geometry information, voiding the need for a predictive model.

Towards explainable message passing networks for predicting carbon dioxide adsorption in metal-organic frameworks

no code implementations2 Dec 2020 Ali Raza, Faaiq Waqar, Arni Sturluson, Cory Simon, Xiaoli Fern

Metal-organic framework (MOFs) are nanoporous materials that could be used to capture carbon dioxide from the exhaust gas of fossil fuel power plants to mitigate climate change.

Counterfactual Regularization for Model-Based Reinforcement Learning

no code implementations25 Sep 2019 Lawrence Neal, Li Fuxin, Xiaoli Fern

In sequential tasks, planning-based agents have a number of advantages over model-free agents, including sample efficiency and interpretability.

Description-Based Zero-shot Fine-Grained Entity Typing

no code implementations NAACL 2019 Rasha Obeidat, Xiaoli Fern, Hamed Shahbazi, Prasad Tadepalli

Fine-grained Entity typing (FGET) is the task of assigning a fine-grained type from a hierarchy to entity mentions in the text.

Open Set Learning with Counterfactual Images

no code implementations ECCV 2018 Lawrence Neal, Matthew Olson, Xiaoli Fern, Weng-Keen Wong, Fuxin Li

In open set recognition, a classifier must label instances of known classes while detecting instances of unknown classes not encountered during training.

Event Detection with Neural Networks: A Rigorous Empirical Evaluation

no code implementations EMNLP 2018 J. Walker Orr, Prasad Tadepalli, Xiaoli Fern

Detecting events and classifying them into predefined types is an important step in knowledge extraction from natural language texts.

A Lipschitz Exploration-Exploitation Scheme for Bayesian Optimization

no code implementations30 Mar 2012 Ali Jalali, Javad Azimi, Xiaoli Fern, Ruofei Zhang

The exploration phase aims to select samples that shrink the search space as much as possible.
