Piecewise linear model
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
Piecewise linear model was published by University of Kansas, in United States of America, in November 1973. academia is the category the publisher falls under.
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
It was trained on about 314 tokens of text.
The reason it appears in this catalogue at all is historical significance,Highly cited.
Answers
Piecewise linear model — common questions
What GPU do I need to run Piecewise linear model?
None. Piecewise linear model 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 Piecewise linear model open source?
The licensing for Piecewise linear model 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 Piecewise linear model have?
Piecewise linear model has 0.4K parameters. 16 input features + bias = 17 input features 7*6/2 = 21 Hyperplanes 17*21 = 357 parameters "For the multicategory problem involving NR categories, a total of NR(NR - 1)/2 hyperplanes are used to partition the pattern space." "The input variables to the classifier consisted of the mean variance of the four textural features (f1,f2,f3, andfg obtained from the distance 1 gray-tone spatial-dependence matrices) and eight spectral features (comprised of the mean variance of the image gray-tone values) in each of the four spectral bands". 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 Piecewise linear model?
Piecewise linear model was published by University of Kansas, based in United States of America, categorised as academia.
When was Piecewise linear model released?
Piecewise linear model was published in November 1973. 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 Piecewise linear model used for?
Piecewise linear model works in Vision, and is recorded as handling image classification. 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.
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.
