Alexa is Implementing Self-Learning Techniques To Better Understand Users (theverge.com)

In a developer blog post published this week, Alexa AI director of applied science Ruhi Sarikaya detailed the advances in machine learning technologies that have allowed Alexa to better understand users through contextual clues. From a report: According to Sarikaya, these improvements have played a role in reducing user friction and making Alexa more conversational. Since this fall, Amazon has been working on self-learning techniques that teach Alexa to automatically recover from its own errors. The system has been in beta until now, and it launched in the US this week. It doesn't require any human annotation, and, according to Sarikaya, it uses customers' "implicit or explicit contextual signals to detect unsatisfactory interactions or failures of understanding."

The contextual signals range from customers' historical activity, preferences, and what Alexa skills they use to where the Alexa device is located in the home and what kind of Alexa device it is. For example, during the beta phase, Alexa learned to understand a customer's mistaken command of "Play 'Good for What'" and correct them by playing Drake's song "Nice for What."

      Good idea! Then they will be able to collect faces of people seen in front of the camera, associate those faces with ones seen on other devices and social media, and sell you stuff whenever their birthday is coming up, or suggest that you take them to certain places for a meal, movie, etc based on collected data and whichever company paid them the most to promote them.

      Then when the govt comes a knocking, there will be a nice treasure trove of information. Of course this information will only be used by the govt to solve serious crime, not for petty reasons.

    That products like these are not to help people, that is an (un)intended consequence, but
    a paid-for-by-the-consumer experiment for data collection and group analysis for control.
    This is not a tin-foil hat theory. Think about it, they known everything about you in your home --
    SPL, temperature, ambient light, how often you (and your children) have visitors), and
    background noise (yes, that background noise as well) to name a few.

    Do they operate as a smoke detector as well? Thought so...

      Not tin foil hat at all - in fact, I'd say it's well accepted that these devices are personal data vacuums. But in the oblivious mass consumer's mind, they have to have this new toy they can talk to. Privacy? "I have nothing to hide", "they already have all my data", "huh?"
      I'm not a psychologist, but I suspect there's only so many things humans can care about. Like when I do my taxes, my eyes glaze over yet I have absolutely no desire to learn more than the absolute minimum to get it done. Maybe the average consumer feels that way about computers and their privacy implications.

      Alexa has a combination of first mover and scale going for it which means it gets a lot of press coverage, but I've seen very little that implies it's extraordinary. To be fair to Amazon, if they have found genuinely effective way to have Alexa learn to interpret users "incorrect" commands or commands where it didn't deliver the desired response, and respond to that then this is quite an improvement. People don't want to have to use rigid command structures to interact, and from my limited experience with Alexa it seemed like it relied on exactly that (while Google was better at handling informal commands).

      I've tried both. On the low end - Home Mini vs Dot - the Echo device wins by a mile on hearing its wake word in a noisy room while music is playing and still picking up what you want to say.

    Try asking it to clear your notifications. **EVERY TIME** she will ask you, "Delete all your notifications, right?" I understand it's to kep noobs from accidentally deleting all their notification but If I have answered "Yes" for a solid year, it really should be smart enough to stop asking. After the 100th plus time, it should have said, "I see you want this to be your default - I won't ask again. If you want to change this, go into settings etc." This is a simple, localized branch and should be a knock off for the devs. It's constantly talked about in forums and I've submitted at least three requests myself.
