Dimensionality Reduction
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.

Size
How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.
- Parameters
- 3.8M
- Training data
- 47,040,000 tokens
After fine-tuning on all 60,000 training images, the autoencoder was tested on 10,000 new images and produced much better reconstructions than did PCA (Fig. 2B)

What the numbers mean
What this model is
Dimensionality Reduction was published by University of Toronto, in Canada, in July 2006. academia is the category the publisher falls under.
It works in Vision, and is recorded as doing face recognition.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Training and provenance
It was trained on about 47,040,000 tokens of text.
It is tracked in the underlying dataset for one reason in particular: highly cited.
Answers
Dimensionality Reduction — common questions
What GPU do I need to run Dimensionality Reduction?
None. Dimensionality Reduction 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.
Is Dimensionality Reduction open source?
The licensing for Dimensionality Reduction was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
How many parameters does Dimensionality Reduction have?
Dimensionality Reduction has 3.8M parameters. 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.
Who created Dimensionality Reduction?
Dimensionality Reduction was published by University of Toronto, based in Canada, categorised as academia.
When was Dimensionality Reduction released?
Dimensionality Reduction was published in July 2006. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
What is Dimensionality Reduction used for?
Dimensionality Reduction works in Vision, and is recorded as handling face recognition. These are the areas it was designed around; they describe intent rather than a hard boundary.
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.
