How do you stop piracy on something like this? Surely I could take a model, refine it slightly to get distinct weights (ie. not a flat clone) and unload it as my own novel variant? ...and I mean, is the problem not utterly fundamental? When is a model “yours” or sell? When you trained it? When you’re not using transfer learning? When you wrote the paper? When you own the training data? When you can recreate it from s…

The value of these could be in private datasets. Model architectures are not really patentable and ownership of a trained model has always been very muddy water. That being said, if I am selling a bird classifier chances are that to train it I had to combine multiple datasets and someone can't easily finetune it to get better results.

The marketplace should probably be on datasets.

Disclaimer: I'm not very familiar with the current state of CV and the way models are trained.

What authors could do is train the model on a dataset, but add a specific image that it flags as a key.

That way, if you keep the image private, you can check if a model is a clone of yours if recognises that specific image.

I'd rather buy a model than a dataset that I have to spend money to train a model with.

I can see value in being able to casually integrate vision models into different applications. I would urge everyone involved (OpenCV and people using the models) to not use this in any safety related application. The example given on the site is person detection for construction site safety. If you're going to use ML for something like this, hire someone with experience using it for such applications, that can under…

I can see the lawsuits already

Interesting concept. Would be great to have more technical details about how a model performs. Having a sense of the size, accuracy, platforms supported, and other simple benchmarks would be really helpful to evaluate a model before making a purchase.

You are limited in expanding your dataset and making your model better, if you only have the model. And I would rather see how clean/balanced the dataset my model was built from was.

If this becomes something like huggingface for Computer Vision - awesome. For now, it's a shame model descriptions seem to often be lifted straight from README. Having a more standardized description, something like model cards [1] (CV example [2]) would be hugely beneficial IMO. [1] https://arxiv.org/pdf/1810.03993.pdf [2] https://drive.google.com/file/d/1f39lSzU5Oq-j_OXgS67KfN5wNso...

I hadn't heard of model cards before - thanks for the link!

I wonder how feasible it would be to develop some formal ontology to describe the capabilities of models and attach them to model cards.

That could open up some interesting applications:

* automated search for a set of models to accomplish some task

* a human usable search engine for finding specific models

EDIT: to complete a sentence

I don't think this will be a successful business model. Niche AI models cost a lot of money to gather the right dataset and train, but they would probably only sell to <100 companies/individuals. So pricing a model at $50-100 isn't profitable. If you're selling general CV models, you have to compete with the plethora of open source ones, including ones that Google and Facebook release for free, which are trained on h…

Are they selling models or making introductions? As you say, niche models have small audiences which makes it all the more likely the models will require modifications. Discussing those modifications provides an opening to adjust the pricing.

When using models becomes more mainstream, I think it's better to strive for transparency than expandability.
