Fair Generalized Linear Models with a Convex Penalty

1 code implementation18 Jun 2022 Hyungrok Do, Preston Putzel, Axel Martin, Padhraic Smyth, Judy Zhong

In addition, we demonstrate that the fair GLM can generate fair predictions for a range of response variables, other than binary and continuous outcomes.

Automating Data Science: Prospects and Challenges

no code implementations12 May 2021 Tijl De Bie, Luc De Raedt, José Hernández-Orallo, Holger H. Hoos, Padhraic Smyth, Christopher K. I. Williams

Given the complexity of typical data science projects and the associated demand for human expertise, automation has the potential to transform the data science process.

Variational Beam Search for Novelty Detection

no code implementations pproximateinference AABI Symposium 2021 Aodong Li, Alex James Boyd, Padhraic Smyth, Stephan Mandt

We consider the problem of online learning in the presence of sudden distribution shifts, which may be hard to detect and can lead to a slow but steady degradation in model performance.

User-Dependent Neural Sequence Models for Continuous-Time Event Data

1 code implementation NeurIPS 2020 Alex Boyd, Robert Bamler, Stephan Mandt, Padhraic Smyth

Modeling such data can be very challenging, in particular for applications with many different types of events, since it requires a model to predict the event types as well as the time of occurrence.

Can I Trust My Fairness Metric? Assessing Fairness with Unlabeled Data and Bayesian Inference

no code implementations NeurIPS 2020 Disi Ji, Padhraic Smyth, Mark Steyvers

We investigate the problem of reliably assessing group fairness when labeled examples are few but unlabeled examples are plentiful.

Dropout as a Structured Shrinkage Prior

1 code implementation9 Oct 2018 Eric Nalisnick, José Miguel Hernández-Lobato, Padhraic Smyth

We propose a novel framework for understanding multiplicative noise in neural networks, considering continuous distributions as well as Bernoulli noise (i. e. dropout).

Mondrian Processes for Flow Cytometry Analysis

no code implementations21 Nov 2017 Disi Ji, Eric Nalisnick, Padhraic Smyth

Analysis of flow cytometry data is an essential tool for clinical diagnosis of hematological and immunological conditions.

Learning Approximately Objective Priors

no code implementations4 Apr 2017 Eric Nalisnick, Padhraic Smyth

Informative Bayesian priors are often difficult to elicit, and when this is the case, modelers usually turn to noninformative or objective priors.

Bayesian Non-Homogeneous Markov Models via Polya-Gamma Data Augmentation with Applications to Rainfall Modeling

no code implementations11 Jan 2017 Tracy Holsclaw, Arthur M. Greene, Andrew W. Robertson, Padhraic Smyth

We extend such models to introduce additional non-homogeneity into the emission distribution using a generalized linear model (GLM), with data augmentation for sampling-based inference.

A Scale Mixture Perspective of Multiplicative Noise in Neural Networks

no code implementations10 Jun 2015 Eric Nalisnick, Anima Anandkumar, Padhraic Smyth

Corrupting the input and hidden layers of deep neural networks (DNNs) with multiplicative noise, often drawn from the Bernoulli distribution (or 'dropout'), provides regularization that has significantly contributed to deep learning's success.

Hot Swapping for Online Adaptation of Optimization Hyperparameters

no code implementations20 Dec 2014 Kevin Bache, Dennis Decoste, Padhraic Smyth

We describe a general framework for online adaptation of optimization hyperparameters by `hot swapping' their values during learning.

Stochastic Collapsed Variational Bayesian Inference for Latent Dirichlet Allocation

no code implementations10 May 2013 James Foulds, Levi Boyles, Christopher DuBois, Padhraic Smyth, Max Welling

We propose a stochastic algorithm for collapsed variational Bayesian inference for LDA, which is simpler and more efficient than the state of the art method.
