Presented my first ever conference paper, "Online Motion Planning Over Multiple Homotopy Classes with Gaussian Process Inference" yesterday at IROS 2019. Absolutely unreal experience! Extremely thankful for all the role models I've had.

Imagine you told a robot to "find your car keys" in your apartment and it looked around, opened a drawer, and retrieved them for you. As a step towards that, I adapted TiPToP to run on the RBY1 humanoid in our lab! Here's an example instruction it follows: "Put the green block on the blue plate and the yellow block on the magazine." TiPToP helps plan over the right arm + single torso joint, but it's easy to unlock more joints -- even the base wheels -- for more expressive, real-world tasks. Humans find objects without thinking twice. One day, robots will too! 🤖

State-of-the-art robot policies often need hundreds of hours of data. What if we needed none? Introducing TiPToP: a manipulation system that zero-shots open-world tasks from pixels and language using vision foundation models and GPU-parallelized Task and Motion Planning (TAMP).

Can we get robots to improve at long-horizon tasks without supervision? Our latest work tackles this problem by planning to practice! Here's a teaser showing initial task -> autonomous practice -> eval (+ interference by a gremlin👿)

Ever heard about "Bilevel Planning" or "Task and Motion Planning", but been unsure what those words mean? Ever wanted a gentle intro to these methods so you can just understand what's going on? Our new blog post might help! lis.csail.mit.edu/bilevel-planni…

Excited about sampling-based MPC but tired of assuming everything is a Gaussian and unsure about the right way to adapt the distribution online? Check out our #CoRL2022 paper on "Learning Sampling Distributions for Model Predictive Control"! (1/8) Paper: arxiv.org/abs/2212.02587

Really excited to share that my latest project, KineCAM, was featured on @MIT News! It's an instant camera that produces "moving" photographs: news.mit.edu/2022/new-twist…

It is insane that while MIT's endowment grew by over $9 BILLION in 2021, nearly 1 in 4 grad students struggle to keep up with cost of living. I say to MIT: invest in your students. I stand in solidarity with @MITGradUnion in their efforts to form a union.

Our very own Rachel Holladay gave a recent guest lecture presenting a conceptual intro to task and motion planning (TAMP). Check it out if you'd like to learn more about the big ideas behind TAMP + some of our group's recent work in this vein! youtube.com/watch?v=A-goUw…

Maybe instead of just epistemic and aleatoric uncertainty, we need a third option which measures how uncertain you are about which of these words to use

Check out our EMNLP paper, some of the first work I've contributed to as a PhD student in @jhuclsp! We performed extensive experiments comparing various data projection pipelines to zero-shot training on 5 cross-lingual information extraction tasks.
Shijie Wu@EzraWu

Q: What's the best choice to improve zero-shot cross-lingual transfer performance if u can’t manually annotate any data? A: The best setup is task dependent, so try multiple setups! 📈 Check out our #EMNLP2021 paper “Everything Is All It Takes” arxiv.org/abs/2109.06798 [1/4]

Many amazing ML/Robotics PhDs I've mentored have come from non-CS backgrounds. It can be scary at first, so I started summer bootcamps: I give a chalk talk & students take turns writing a blog & creating a coding PSet. The first 4 blogs are now online! tiny.cc/mholtz

I'm just going to go ahead and say it. Working & staying motivated after a year of pandemic + political turmoil + isolation is 𝘀𝘁𝗶𝗹𝗹 𝗵𝗮𝗿𝗱. You might think that me, or your colleagues, or someone else in your attention network breezes through it. That's a lie.

please consider signing this open letter aiming to help junior women in math. the pandemic is affecting everyone's productivity and careers, but women and untenured faculty are more affected. hiring & promotion committees should take this into account. europeanwomeninmaths.org/ewm-open-lette…
