This is something I built while learning RL, and I decided to open-source. I noticed that every major RL algorithm (Actor Critic, A2C, PPO, TD3 etc.) would be written from scratch,…

It's great, astounding, divine, amazing, splendiferous.

There are plenty of demo videos on Twitter: https://x.com/colin_d_m

The motion tracking system used by ARKit/ARCore is called SLAM, combination of sensors + camera data if available.

Great question. Partly on device compatibility, but mostly that we can achieve an amazing, reliable experience right now without those anchors. If we weren't getting the accuracy w…

We've had the solution live in stores for years without any issue. Our algorithms can clean up and filter out unreliable data, based on all of the other data we have, from other AP…

Thank you! I tried to keep it interesting but not get lost in rabbit holes. We have around 300 hours of ground-truth data now, in 1-second intervals, which we use for algorithm tra…

Thanks for the feedback. I wanted to keep it balanced to be accessible but also insightful. To answer your point: we have the digital map, can use that to understand obstacles etc …

All of the videos shown on the speed-run of our technology is on 4 year-old Android devices, such as Samsung S21, Pixel 6 etc.. We always test and gather statistics on older device…

Thanks. Very interested in robotics so that'd be an ideal home, given the SLAM + sensors tech stack.

Yes - one of the limitations with mobile is engaging the camera/quality of the SLAM. With a robot, they're already using SLAM with strong tracking, and controlling the hardware sta…

Aside from saving time, I'm bad at writing. Especially emails. I often open ChatGPT, paste in the whole email chain, write out the bullets of the points I want to make and ask it t…

You could say the same about software and app stores. If safety were the top priority, then the safest option is to say no apps, but that isn't competitive or lucrative. Apple's ap…

Do you track how many people clicked each confetti button?

Fun at parties.

Monzo is another company which does this incredibly well, and wrote a public document on it: https://monzo.com/tone-of-voice/ I'd love to read more on this topic - how companies le…

Looks promising. One feature I'd need is ability to change the resolution to vertical - the same as the video I'm inputting.
