  • A guy is driving around the back woods of Montana and he sees a sign in front of a broken down shanty-style house: ‘Talking Dog For Sale.’

    He rings the bell and the owner appears and tells him the dog is in the backyard.

    The guy goes into the backyard and sees a nice looking Labrador Retriever sitting there.

    “You talk?” he asks.

    “Yep” the Lab replies.

    After the guy recovers from the shock of hearing a dog talk, he says, “So, what’s your story?”

    The Lab looks up and says, “Well, I discovered that I could talk when I was pretty young. I wanted to help the government, so I told the CIA. In no time at all they had me jetting from country to country, sitting in rooms with spies and world leaders, because no one figured a dog would be eavesdropping, I was one of their most valuable spies for eight years running… but the jetting around really tired me out, and I knew I wasn’t getting any younger so I decided to settle down. I signed up for a job at the airport to do some undercover security, wandering near suspicious characters and listening in. I uncovered some incredible dealings and was awarded a batch of medals. I got married, had a mess of puppies, and now I’m just retired.”

    The guy is amazed. He goes back in and asks the owner what he wants for the dog.

    “Ten dollars” the guy says.

    “Ten dollars? This dog is amazing! Why on Earth are you selling him so cheap?”

    “Because he’s a liar. He’s never been out of the yard.”

    Edit: sorry, just noticed your account is on programming.dev, where there’s no such option? Then I’m afraid I don’t know :/

    Edit 2: From the programming.dev sidebar:

    Community Creation

    Communities in our instance are created from our community request zone. If you have an idea for a community that fits our instance that hasnt been made already feel free to create a post for it there. Communities will be considered for creation if theres enough interest in the idea shown by people upvoting it






  • What they’re saying, as far as I can tell, is that after training the model on 85% of the dataset, the model predicted whether a participant had an ASD diagnosis (as a binary choice) 100% correctly for the remaining 15%. I don’t think this is unheard of, but I’ll agree that a replication would be nice to eliminate systemic errors. If the images from the ASD and TD sets were taken with different cameras, for instance, that could introduce an invisible difference in the datasets that an AI could converge on. I would expect them to control for stuff like that, though.


  • From TFA:

    For ASD screening on the test set of images, the AI could pick out the children with an ASD diagnosis with a mean area under the receiver operating characteristic (AUROC) curve of 1.00. AUROC ranges in value from 0 to 1. A model whose predictions are 100% wrong has an AUROC of 0.0; one whose predictions are 100% correct has an AUROC of 1.0, indicating that the AI’s predictions in the current study were 100% correct. There was no notable decrease in the mean AUROC, even when 95% of the least important areas of the image – those not including the optic disc – were removed.

    They at least define how they get the 100% value, but I’m not an AIologist so I can’t tell if it is reasonable.
