MatrixFac for Recommenders

Closed weights Yahoo Research,AT&T August 2009

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.

Answers

MatrixFac for Recommenders — common questions

01

MatrixFac for Recommenders— how many parameters does it have?

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

02

MatrixFac for Recommenders— who created it?

It was published by Yahoo Research,AT&T, based in United States of America, an organisation categorised as industry,Industry.

03

MatrixFac for Recommenders— when was it released?

It was published in August 2009. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

04

MatrixFac for Recommenders— what is it used for?

It works in the domain of Recommendation, and is recorded as handling the task of recommender system. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

05

MatrixFac for Recommenders— what GPU do I need to run it?

None. This 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.

06

MatrixFac for Recommenders— is it open source?

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

The other direction

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.
