The Spectral Neuron
Alex Shtoff
As machine learned models increase in complexity and expressive power, features of simpler models, such as intrinsic coefficient transparency and control over the shape of the mode…
tensorFM: Low-Rank Approximations of Cross-Order Feature Interactions
Alessio Mazzetto, Mohammad Mahdi Khalili, Laura Fee Nern +3
We address prediction problems on tabular categorical data, where each instance is defined by multiple categorical attributes, each taking values from a finite set. These attribute…
LiveRAG: A diverse Q&A dataset with varying difficulty level for RAG evaluation
David Carmel, Simone Filice, Guy Horowitz +4
With Retrieval Augmented Generation (RAG) becoming more and more prominent in generative AI solutions, there is an emerging need for systematically evaluating their effectiveness.…
A Simple Method for PMF Estimation on Large Supports
Alex Shtoff
We study nonparametric estimation of a probability mass function (PMF) on a large discrete support, where the PMF is multi-modal and heavy-tailed. The core idea is to treat the emp…
Steady Continuous Monitoring is (Just Barely) Impossible for Tests of Unbounded Length
Eric Bax, Alex Shtoff
AB testing evaluates the difference between a control and a treatment in a statistically rigorous manner. Continuous monitoring allows statistical evaluation of an AB test as it pr…
Function Basis Encoding of Numerical Features in Factorization Machines
Alex Shtoff, Elie Abboud, Rotem Stram +1
Factorization machine (FM) variants are widely used for large scale real-time content recommendation systems, since they offer an excellent balance between model accuracy and low c…
