Regularized SVD for Collaborative Filtering

Closed weights Warsaw University August 2007

No estimate

No hardware requirements for this model

The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.

On record

Full specification

Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean

Background

Regularized SVD for Collaborative Filtering was published by Warsaw University, in Poland, in August 2007. The organisation is categorised as academia.

It works in Recommendation, and is recorded as doing recommender system.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

Training and provenance

The training set ran to roughly 100,480,507 tokens.

Answers

Regularized SVD for Collaborative Filtering — common questions

01

Who created Regularized SVD for Collaborative Filtering?

Regularized SVD for Collaborative Filtering was published by Warsaw University, based in Poland, categorised as academia.

02

When was Regularized SVD for Collaborative Filtering released?

Regularized SVD for Collaborative Filtering was published in August 2007. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

03

What is Regularized SVD for Collaborative Filtering used for?

Regularized SVD for Collaborative Filtering works in Recommendation, and is recorded as handling recommender system. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.

04

What GPU do I need to run Regularized SVD for Collaborative Filtering?

None. Regularized SVD for Collaborative Filtering is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.

05

Is Regularized SVD for Collaborative Filtering open source?

The licensing for Regularized SVD for Collaborative Filtering was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

06

How many parameters does Regularized SVD for Collaborative Filtering have?

No parameter count has been published for Regularized SVD for Collaborative Filtering, which is why no memory or speed figure appears on this page.

Looking at it from the other side?

This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
