I'm an EECS PhD candidate at Technion under the supervision of Aviv Tamar. Interested in how agents "sense to act" and "act to sense" in the world.

The first ever hand-held, 3D, real-time, general tactile imaging system. We leverage the fact that touch is a local sensation, using a grid of local, compositional encoders instead of a global one. We generalize from single-inclusion training to multi-inclusion objects it's never seen — and it even works hand-held, no robot arm required.
Humans learn to understand touch by playing with countless toys as kids. We do the same for robots: a tactile sensor palpates soft phantoms for hundreds of hours, learning a representation of touch from scratch. The result — a robot that detects lumps in soft tissue far more accurately than the human hand.
How do you specialize a generalist robot policy without breaking what makes it generalist? Task Tokens teach a frozen behavior foundation model new tricks via a lightweight, RL-trained encoder — no fine-tuning required. The model keeps its diverse control skills while getting sharper at the task you actually care about.
Meta-RL agents are notoriously sample-hungry and struggle past low-dimensional tasks. MAMBA fuses world models with meta-RL to learn new tasks up to 15x faster, with barely any hyperparameter tuning. It also holds up on much harder, higher-dimensional domains — a real step toward generalizing agents.
What if a neural network's weights were themselves the output of another neural network? NeRN assigns each convolutional kernel a coordinate and learns a predictor that maps coordinates straight to weights — reconstructing full CNNs on CIFAR-10, CIFAR-100, and ImageNet with smoothness and distillation tricks to keep it stable.
How many training tasks does meta-RL actually need? We show the answer hinges on the intrinsic dimension of the task distribution, not the number of states and actions — and prove it by learning that distribution directly with kernel density estimation, yielding tighter bounds and better real-world generalization.
Can you drop a dancer into someone else's living-room video and make it look real? We call it Scene Aware Motion Transfer: a fully automatic pipeline that tracks individual identities in crowded, in-the-wild footage and transfers motion onto them, seamlessly integrated into the real scene.
