haha definitely, PPO is not the most sample efficient method for sure

Hi HN, Andrea (the author) here. This is the last post of my series on quadcopter simulation and (Reinforcement Learning based) control. This post is less educational that the othe…

Hi, thanks! Love your product, it's been incredible for debugging simulations as well as looking at individual policy rollouts (instead of e.g. static videos) to design better rewa…

Hi HN, Andrea (the author) here. I'm continuing my series of blog posts on quadcopter simulation and (Reinforcement Learning based) control. This one is the second in the series, f…

Yeah, I did. I didn't implement disturbances like wind, so a very simple PD position controller was enough for stabilization or simple trajectory tracking. I won't focus too much o…

You are technically correct - the best kind of correct. But yeah, think of it as a "slice" of a quadcopter along one of its principal axes. Writing the 3D blog post right now.

Good question, haven't really thought about modeling complex effects besides prop aerodynamic drag. If I were to start, I'd probably look at the model described in the "Aerodynamic…

Author here. I've spent the last six months replicating the paper "Champion-level drone racing using deep reinforcement learning" and now I'm writing down the blog posts I wish I h…

Thanks!

How would you publicly release code from a recently published paper? I have some python notebooks and would like to present them as a library. Should I use docker? Pipenv? Poetry?

Interesting question, from my understanding Pathfinder is only concerned with rendering so it doesn't completely replace FreeType: you still need some software to extract the curve…

Absolutely, Subpixel AA, Kerning, Ligatures, Gamma Blending, and Emojis will be treated

Thanks :) I've used what was available on the latest ubuntu lts. FreeType functions return 0 (FT_Err_Ok) on success or a specific value for each function, but yes I agree that erro…

I agree that it's an interesting topic. On reddit one of the authors of dear imgui has some interesting thought on it: https://www.reddit.com/r/programming/comments/cfxltf/modern_.…

Looks like something I did some time ago[0], nice to see that this space is being explored. Wikum[1] from MIT's CSAIL is also an interesting alternative. [0] https://mrandri19.gith…
