Dog training generally requires a human dog trainer, but what if it didn't and delivered better results? That's the promise of a startup called Companion Labs that has unveiled its first AI-driven dog-training machine in conjunction with the San Francisco SPCA. The CompanionPro trainer looks like a Soviet-era space heater but contains image sensors, a Google Edge TPU AI processor, wireless connectivity, lights, a speaker and a proprietary "treat launcher" that delivers all-important training rewards. Computer vision is key to how the machine works, detecting a dog's comportment in real time to tune its delivery of rewards to reinforce desired behavior. It remains to be seen how well it can approximate the experience of a skilled human trainer, though SF SPCA says it will soon release a peer-reviewed case study on how the machine worked with one dog suffering from separation anxiety which, by definition, manifests itself when no trainer is around to address it.
