Quantum Natural Language Processing

no code implementations28 Mar 2024 Dominic Widdows, Willie Aboumrad, Dohun Kim, Sayonee Ray, Jonathan Mei

In this context, we argue that "hallucinations" in modern artificial intelligence systems are a misunderstanding of the way facts are conceptualized: language can express many plausible hypotheses, of which only a few become actual.

KrADagrad: Kronecker Approximation-Domination Gradient Preconditioned Stochastic Optimization

1 code implementation30 May 2023 Jonathan Mei, Alexander Moreno, Luke Walters

Second order stochastic optimizers allow parameter update step size and direction to adapt to loss curvature, but have traditionally required too much memory and compute for deep learning.

SKI to go Faster: Accelerating Toeplitz Neural Networks via Asymmetric Kernels

no code implementations15 May 2023 Alexander Moreno, Jonathan Mei, Luke Walters

For the low rank component, we replace the RPE MLP with linear interpolation and use asymmetric Structured Kernel Interpolation (SKI) (Wilson et.

Single Index Latent Variable Models for Network Topology Inference

EigenNetworks

no code implementations5 Jun 2018 Jonathan Mei, José M. F. Moura

Algorithms for learning the time series of graphs $\left\{G_k\right\}$, deriving the eigennetworks, eigenfeatures and eigentrajectories, and detecting changepoints are presented.

Signal Processing on Graphs: Causal Modeling of Unstructured Data

no code implementations28 Feb 2015 Jonathan Mei, José M. F. Moura

Many applications collect a large number of time series, for example, the financial data of companies quoted in a stock exchange, the health care data of all patients that visit the emergency room of a hospital, or the temperature sequences continuously measured by weather stations across the US.
