Variable-Complexity Weighted-Tempered Gibbs Samplers for Bayesian Variable Selection

no code implementations6 Apr 2023 Lan V. Truong

However, the Rao-Backwellized estimator associated with this sampler has a high variance as the ratio between the signal dimension and the number of conditional PIP estimations is large.

Global Convergence Rate of Deep Equilibrium Models with General Activations

no code implementations11 Feb 2023 Lan V. Truong

In a recent paper, Ling et al. investigated the over-parametrized Deep Equilibrium Model (DEQ) with ReLU activation.

Generative Adversarial Nets: Can we generate a new dataset based on only one training set?

no code implementations12 Oct 2022 Lan V. Truong

In this work, we aim to generate a new dataset that has a different distribution from the training set.

On Rademacher Complexity-based Generalization Bounds for Deep Learning

no code implementations8 Aug 2022 Lan V. Truong

We show that the Rademacher complexity-based approach can generate non-vacuous generalisation bounds on Convolutional Neural Networks (CNNs) for classifying a small number of classes of images.

Fundamental limits and algorithms for sparse linear regression with sublinear sparsity

no code implementations27 Jan 2021 Lan V. Truong

We establish exact asymptotic expressions for the normalized mutual information and minimum mean-square-error (MMSE) of sparse linear regression in the sub-linear sparsity regime.

Replica Analysis of the Linear Model with Markov or Hidden Markov Signal Priors

no code implementations28 Sep 2020 Lan V. Truong

This paper estimates free energy, average mutual information, and minimum mean square error (MMSE) of a linear model under two assumptions: (1) the source is generated by a Markov chain, (2) the source is generated via a hidden Markov model.

Support Recovery in the Phase Retrieval Model: Information-Theoretic Fundamental Limits

no code implementations30 Jan 2019 Lan V. Truong, Jonathan Scarlett

The support recovery problem consists of determining a sparse subset of variables that is relevant in generating a set of observations.
