    Anyone who thinks vision has already largely been solved in AI is kidding themselves. Object recognition ≠ scene comprehension.https://twitter.com/skeptoptimist/status/1031808308154261504 …

    Replying to @GaryMarcus
    Agreed. The OpenAI Five project should not be about implementing AI vision (converting from pixels) and having the OpenAI team waste time on solving a problem that has already largely been solved.

        Replying to @GaryMarcus

        Agreed. It is worth noting, however, that scene comprehension is not a bounded task. People do not comprehend everything about a scene. So it is not easy to define what it means to "solve" scene comprehension.

        agree in the general case; here it would be operationalized by taking DoTA images in and converting them to the DoTA buffers @openAi used, and showing that this could work in novel scenarios (much easier than the general case).

        You don't need to have vision solved. You stated OpenAI js "ducking some of the hardest problems like knowing what entities exist and how to segment them etc.", but that subset of vision (detection + segmentation of a discrete known number of object given sim access) is not hard

        Not hard for supervised learning, or not hard for unsupervised/RL? And not hard because DOTA has simple graphics, or not hard period?

        It's much, much worse than that. Unlike DNNs, the brain can instantly see a complex object it has never seen before, i.e., without a prior representation. Still, you, Marcus, insist on calling for changes to the current representationalist DL paradigm. This is pathetic, man.

        Given what I wrote above, if anybody still thinks that deep learning has any role to play in the future of computer vision or AGI, he or she is either stupid or a charlatan. Which do you want to be, Marcus? Either way, you will be just a footnote in the history of AI. 🤪😁

        Amen. And even (to paraphrase Rudy Guiliani), "object recognition" ≠ object recognition. That is, "object recognition" as in ImageNet has been "solved", sort of, but object recognition in real life is far from solved.
