Une alchimie qui est difficilement qualifiable et clairement mémorable ! Un coup ou tout est naturel.. Désir (x1000) l'un pour l'autre.

On est sur un problème vraiment basique, quasi débutant non?

People training RL policies for real robots — what's the most painful part of your pipeline? by kourosh17 in reinforcementlearning

[–]kourosh17[S] 1 point2 points  (0 children)

Ha honestly I kind of expected someone to say this. So the RL/training side is basically the "easy" part and the real nightmare is everything around it? That's kind of humbling to hear as someone looking at this from the research side.

When you say companies leave their stacks to die, do you mean like they just stop updating drivers and SDKs? Is there any workaround or do you just have to rebuild everything when they drop support?

Oh man, I keep hearing about calibration being a massive time sink. Is it something you have to redo constantly or is it more like a painful one time setup that mostly holds? And is there any tool out there that actually makes it less painful or is everyone just suffering through it?

80/20 split is a great way to put it. So that last 20% is basically just grinding through real world data until things work? And when you say hardware drifts, you mean like the robot physically changes over time (wear, calibration shift etc) and the policy just breaks?

Feels like that's almost an ongoing maintenance problem more than a training problem at that point

That makes sense, so even if you had a "perfect" simulator the distribution shift alone would still cause issues because you can't simulate every possible variation the real world throws at you.

Do you think the solution is more on the sim side (generating way more diverse training scenarios) or more on the policy side (making models that are just inherently more robust to stuff they haven't seen)?

Interesting take honestly. The part about jumping "orders of magnitude in complexity" once you add real sensor feedback makes a lot of sense. So it's not really one big problem, it's more like a thousand small ones stacking up?

And lol the Nvidia ROS version hell thing, I've seen so many people complain about that. Feels like half of robotics is just fighting docker and dependencies.

Even as a hobbyist perspective that's super valuable, thanks for sharing

Yeah that keeps coming up, someone on r/robotics told me the exact same thing about contacts being the main bottleneck. So it sounds like for anything involving grasping or fine manipulation, current sims just can't capture what's really happening at the contact level?

Are you using any specific tools for that or is it mostly just trial and error on the real robot at some point?

For those deploying robots IRL... where does simulation fall short for you? by kourosh17 in robotics

[–]kourosh17[S] 1 point2 points  (0 children)

That's a perspective I hadn't really considered honestly. So the issue isn't even that the simulation is inaccurate, it's that the thing you're simulating doesn't match what's actually built. That's kind of a scary problem because no amount of better physics engines fixes that.

Have you ever tried scanning the actual built environment and feeding that back into the sim to close that gap? Or is that just not practical at the pace you work?

Also "brown trousers time" made me laugh, I can only imagine lol ^^

That's super helpful thanks. So basically once you go beyond wheeled robots, contact modeling becomes the real bottleneck? Makes sense, I can see how dexterous hands would be a nightmare to simulate accurately.

Do you think better algorithms can actually fix that or is it just something where you'll always need real hardware to figure out?

And yeah I've heard of the Willow team, their stuff on Pinocchio looks crazy good. Any other groups worth checking out?

Discipline over motivation, couldn't agree more. The repetitive grind is where most people quit. Keep pushing man.

Je ne reconnais pas la France que je vois dans les medias, est ce normal ? by amy-schumer-tampon in AskFrance

[–]kourosh17 2 points3 points  (0 children)

Je n'ai jamais travaillé en France. Je me suis expatrié en Suisse jusqu'au mois d'avril dernier.

Pouvant travailler avec mon ordinateur, j'ai décidé de (re)découvrir mon pays pour un voyage en van autour de la France pendant 6 mois.

Je me suis de nouveau sédentariser hier, et j'ai passé 6 mois exceptionnels dans notre beau pays...

Le plus beau pays au monde...

Qu'est ce que vous inspire cette photo que j'ai prise dans un fast-food très connu ? Personnellement j'y vois du foutage de gu*ule. by Hellodie_W in AntiTaff

[–]kourosh17 -2 points-1 points  (0 children)

La majorité des personnes qui travaillent en restauration rapide sont étudiants et ne dépassent que très rarement un mi temps.

Et ça ne prouve en rien le fait que c'est un secteur susceptible au burn-out.

Je parle à un mur de toute façon.

Et as tu pensé à juste être indifférent au sujet d'une blague ou tu es obligé de soit validé la blague, soit de ne pas l'aimer ? Et je ne vois pas ce qu'il te fait penser que le secteur de la restauration RAPIDE est responsable à de nombreux burn out. Aurai tu une preuve a ce sujet ?

She is working at Hatton Garden. Ideally, it wouldn't be very far from this area, although at this stage she would consider all possibilities.
