Diffusive Gibbs Sampling

1 code implementation5 Feb 2024 Wenlin Chen, Mingtian Zhang, Brooks Paige, José Miguel Hernández-Lobato, David Barber

The inadequate mixing of conventional Markov Chain Monte Carlo (MCMC) methods for multi-modal distributions presents a significant challenge in practical applications such as Bayesian inference and molecular dynamics.

It HAS to be Subjective: Human Annotator Simulation via Zero-shot Density Estimation

1 code implementation30 Sep 2023 Wen Wu, Wenlin Chen, Chao Zhang, Philip C. Woodland

Human annotator simulation (HAS) serves as a cost-effective substitute for human evaluation such as data annotation and system assessment.

Towards the Better Ranking Consistency: A Multi-task Learning Framework for Early Stage Ads Ranking

no code implementations12 Jul 2023 Xuewei Wang, Qiang Jin, Shengyu Huang, Min Zhang, Xi Liu, Zhengli Zhao, Yukun Chen, Zhengyu Zhang, Jiyan Yang, Ellie Wen, Sagar Chordia, Wenlin Chen, Qin Huang

In order to pass better ads from the early to the final stage ranking, we propose a multi-task learning framework for early stage ranking to capture multiple final stage ranking components (i. e. ads clicks and ads quality events) and their task relations.

Leveraging Task Structures for Improved Identifiability in Neural Network Representations

no code implementations26 Jun 2023 Wenlin Chen, Julien Horwood, Juyeon Heo, José Miguel Hernández-Lobato

This work extends the theory of identifiability in supervised learning by considering the consequences of having access to a distribution of tasks.

Neural Characteristic Activation Value Analysis for Improved ReLU Network Feature Learning

1 code implementation25 May 2023 Wenlin Chen, Hong Ge

This work examines the characteristic activation values of individual ReLU units in neural networks.

Meta-learning Adaptive Deep Kernel Gaussian Processes for Molecular Property Prediction

1 code implementation5 May 2022 Wenlin Chen, Austin Tripp, José Miguel Hernández-Lobato

We propose Adaptive Deep Kernel Fitting with Implicit Function Theorem (ADKF-IFT), a novel framework for learning deep kernel Gaussian processes (GPs) by interpolating between meta-learning and conventional deep kernel learning.

Optimal Client Sampling for Federated Learning

1 code implementation NeurIPS 2021 Wenlin Chen, Samuel Horvath, Peter Richtarik

We show that importance can be measured using only the norm of the update and give a formula for optimal client participation.

To Ensemble or Not Ensemble: When does End-To-End Training Fail?

1 code implementation12 Feb 2019 Andrew M. Webb, Charles Reynolds, Wenlin Chen, Henry Reeve, Dan-Andrei Iliescu, Mikel Lujan, Gavin Brown

An interesting question is whether this trend will continue-are there any clear failure cases for E2E training?

Multi-Scale Convolutional Neural Networks for Time Series Classification

2 code implementations22 Mar 2016 Zhicheng Cui, Wenlin Chen, Yixin Chen

These methods are ad-hoc and separate the feature extraction part with the classification part, which limits their accuracy performance.

Optimal Action Extraction for Random Forests and Boosted Trees

1 code implementation13 Aug 2015 Zhicheng Cui, Wenlin Chen, Yujie He, Yixin Chen

To address this problem, we present a novel framework to post-process any ATM classifier to extract an optimal actionable plan that can change a given input to a desired class with a minimum cost.

Compressing Convolutional Neural Networks

no code implementations14 Jun 2015 Wenlin Chen, James T. Wilson, Stephen Tyree, Kilian Q. Weinberger, Yixin Chen

Convolutional neural networks (CNN) are increasingly used in many areas of computer vision.

Compressing Neural Networks with the Hashing Trick

1 code implementation19 Apr 2015 Wenlin Chen, James T. Wilson, Stephen Tyree, Kilian Q. Weinberger, Yixin Chen

As deep nets are increasingly used in applications suited for mobile devices, a fundamental dilemma becomes apparent: the trend in deep learning is to grow models to absorb ever-increasing data set sizes; however mobile devices are designed with very little memory and cannot store such large models.
