RBM Image Classifier

Closed weights University of Toronto 80M parameters April 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.

What the numbers mean

Where it came from

RBM Image Classifier was published by University of Toronto, in Canada, in April 2009. academia is the category the publisher falls under.

It works in Vision, and is recorded as doing image classification.

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

What went into building it

The training set ran to roughly 6,144,050,000 tokens.

Its inclusion criterion is highly cited.

Answers

RBM Image Classifier — common questions

01

What GPU do I need to run RBM Image Classifier?

None. RBM Image Classifier 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.

02

Is RBM Image Classifier open source?

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

03

How many parameters does RBM Image Classifier have?

RBM Image Classifier has 80M parameters. Best performing model (see Figure 3.1) had 10,000 hidden units in one hidden layer and 8000 visible units. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

04

Who created RBM Image Classifier?

RBM Image Classifier was published by University of Toronto, based in Canada, categorised as academia.

05

When was RBM Image Classifier released?

RBM Image Classifier was published in April 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.

06

What is RBM Image Classifier used for?

RBM Image Classifier works in Vision, and is recorded as handling image classification. These are the areas it was designed around; they describe intent rather than a hard boundary.
