Compressed Predictive Information Coding

no code implementations3 Mar 2022 Rui Meng, Tianyi Luo, Kristofer Bouchard

The key insight of our framework is to learn representations by minimizing the compression complexity and maximizing the predictive information in latent space.

Bayesian Inference in High-Dimensional Time-Serieswith the Orthogonal Stochastic Linear Mixing Model

no code implementations25 Jun 2021 Rui Meng, Kristofer Bouchard

Stochastic linear mixing models (SLMM) assume the mixture coefficients depend on input, making them more flexible and effective to capture complex output dependence.

Stochastic Collapsed Variational Inference for Structured Gaussian Process Regression Network

no code implementations1 Jun 2021 Rui Meng, Herbie Lee, Kristofer Bouchard

This paper presents an efficient variational inference framework for deriving a family of structured gaussian process regression network (SGPRN) models.

Sparse and Low-bias Estimation of High Dimensional Vector Autoregressive Models

no code implementations L4DC 2020 Trevor Ruiz, Sharmodeep Bhattacharyya, Mahesh Balasubramanian, Kristofer Bouchard

A well-known feature of RML inference is that in general the technique produces a trade-off between sparsity and bias that depends on the choice of the regularization hyperparameter.

Provably convergent acceleration in factored gradient descent with applications in matrix sensing

no code implementations1 Jun 2018 Tayo Ajayi, David Mildebrath, Anastasios Kyrillidis, Shashanka Ubaru, Georgios Kollias, Kristofer Bouchard

We present theoretical results on the convergence of \emph{non-convex} accelerated gradient descent in matrix factorization models with $\ell_2$-norm loss.

Modeling neural activity at the ensemble level

1 code implementation30 Apr 2015 Joaquin Rapela, Mark Kostuk, Peter F. Rowat, Tim Mullen, Edward F. Chang, Kristofer Bouchard

Here we demonstrate that the activity of neural ensembles can be quantitatively modeled.
