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.

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.

Training data

However, these are 1000 20x20 pixel "bases", not images

Training compute

The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

Training compute

(Just for natural images) "All experiments were conducted on a Linux machine with AMD Opteron 2GHz CPU and 2GB RAM. ... For example, we were able to learn a set of 1,024 bases (each 14×14 pixels)in about 2 hours and a set of 2,000 bases (each 20×20 pixels) in about 10 hours." I filtered for 2GHz Opteron models that came out in 2005, of which there are five: https://www.techpowerup.com/cpu-specs/?mfgr=AMD&released=2005&generation=AMD%20Opteron&sort=name Found a source which indicates 3 cycles …

What the numbers mean

Background

Sparse Vision Encoding was published by Stanford University, in United States of America, in November 2006. The organisation is categorised as academia.

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

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

How it was trained

Producing it required around 9.6 × 10¹² FLOP of arithmetic, which is a statement about the training budget rather than about inference.

Answers

Sparse Vision Encoding — common questions

01

Is Sparse Vision Encoding open source?

No. Sparse Vision Encoding has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does Sparse Vision Encoding have?

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

03

Who created Sparse Vision Encoding?

Sparse Vision Encoding was published by Stanford University, based in United States of America, categorised as academia.

04

When was Sparse Vision Encoding released?

Sparse Vision Encoding was published in November 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.

05

What is Sparse Vision Encoding used for?

Sparse Vision Encoding 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.

06

How much compute was used to train Sparse Vision Encoding?

Around 9.6 × 10¹² FLOP. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.

07

What GPU do I need to run Sparse Vision Encoding?

None. Sparse Vision Encoding 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.

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.
