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

What this model is

R-CNN (T-net) was published by University of California (UC) Berkeley, in the country recorded as United States of America, during November 2013. It comes out of an organisation categorised as academia.

It works in the domain of Vision, and is recorded as performing the task of object detection.

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

How it was trained

It is tracked in the underlying dataset for one reason in particular: highly cited.

Answers

R-CNN (T-net) — common questions

01

R-CNN (T-net)— 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.

02

R-CNN (T-net)— 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.

03

R-CNN (T-net)— how many parameters does it have?

It has a parameter count of 69M. Computed from architecture description in Caffee https://nbviewer.jupyter.org/github/BVLC/caffe/blob/master/examples/detection.ipynb. 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

R-CNN (T-net)— who created it?

It was published by University of California (UC) Berkeley, based in United States of America, an organisation categorised as academia.

05

R-CNN (T-net)— when was it released?

It was published in November 2013. 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

R-CNN (T-net)— what is it used for?

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

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.
