Sequence Modeling with Multiresolution Convolutional Memory

1 code implementation2 May 2023 Jiaxin Shi, Ke Alexander Wang, Emily B. Fox

Popular approaches in the space tradeoff between the memory burden of brute-force enumeration and comparison, as in transformers, the computational burden of complicated sequential dependencies, as in recurrent neural networks, or the parameter burden of convolutional networks with many or large filters.

Simplifying Hamiltonian and Lagrangian Neural Networks via Explicit Constraints

1 code implementation NeurIPS 2020 Marc Finzi, Ke Alexander Wang, Andrew Gordon Wilson

Reasoning about the physical world requires models that are endowed with the right inductive biases to learn the underlying dynamics.

Bayesian Algorithm Execution: Estimating Computable Properties of Black-box Functions Using Mutual Information

1 code implementation19 Apr 2021 Willie Neiswanger, Ke Alexander Wang, Stefano Ermon

Given such an $\mathcal{A}$, and a prior distribution over $f$, we refer to the problem of inferring the output of $\mathcal{A}$ using $T$ evaluations as Bayesian Algorithm Execution (BAX).

SKIing on Simplices: Kernel Interpolation on the Permutohedral Lattice for Scalable Gaussian Processes

1 code implementation12 Jun 2021 Sanyam Kapoor, Marc Finzi, Ke Alexander Wang, Andrew Gordon Wilson

State-of-the-art methods for scalable Gaussian processes use iterative algorithms, requiring fast matrix vector multiplies (MVMs) with the covariance kernel.

Is Importance Weighting Incompatible with Interpolating Classifiers?

1 code implementation ICLR 2022 Ke Alexander Wang, Niladri S. Chatterji, Saminul Haque, Tatsunori Hashimoto

As a remedy, we show that polynomially-tailed losses restore the effects of importance reweighting in correcting distribution shift in overparameterized models.

Interpretable Mechanistic Representations for Meal-level Glycemic Control in the Wild

1 code implementation6 Dec 2023 Ke Alexander Wang, Emily B. Fox

Diabetes encompasses a complex landscape of glycemic control that varies widely among individuals.

$DC^2$: A Divide-and-conquer Algorithm for Large-scale Kernel Learning with Application to Clustering

no code implementations16 Nov 2019 Ke Alexander Wang, Xinran Bian, Pan Liu, Donghui Yan

Analysis on $DC^2$ when applied to spectral clustering shows that the loss in clustering accuracy due to data division and reduction is upper bounded by the data approximation error which would vanish with recursive random projections.

GOPHER: Categorical probabilistic forecasting withgraph structure via local continuous-time dynamics

no code implementations NeurIPS Workshop ICBINB 2021 Ke Alexander Wang, Danielle C. Maddix, Bernie Wang

We consider the problem of probabilistic forecasting over categories with graph structure, where the dynamics at a vertex depends on its local connectivity structure.

Learning Absorption Rates in Glucose-Insulin Dynamics from Meal Covariates

no code implementations27 Apr 2023 Ke Alexander Wang, Matthew E. Levine, Jiaxin Shi, Emily B. Fox

In this paper, we propose to learn the effects of macronutrition content from glucose-insulin data and meal covariates.
