Decentralized and Asymmetric Multi-Agent Learning in Construction Sites

Yakov Miron, Dan Navon, Yuval Goldfracht +2

Multi-agent collaboration involves multiple participants working together in a shared environment to achieve a common goal. These agents share information, divide tasks, and synchr…

CONFIDE: Contextual Finite Differences Modelling of PDEs

Ori Linial, Orly Avner, Dotan Di Castro

We introduce a method for inferring an explicit PDE from a data sample generated by previously unseen dynamics, based on a learned context. The training phase integrates knowledge…

InsertionNet 2.0: Minimal Contact Multi-Step Insertion Using Multimodal Multiview Sensory Input

Oren Spector, Vladimir Tchuiev, Dotan Di Castro

We address the problem of devising the means for a robot to rapidly and safely learn insertion skills with just a few human interventions and without hand-crafted rewards or demons…

BIDCD -- Bosch Industrial Depth Completion Dataset

Adam Botach, Yuri Feldman, Yakov Miron +2

We introduce BIDCD -- the Bosch Industrial Depth Completion Dataset. BIDCD is a new RGBD dataset of metallic industrial objects, collected with a depth camera mounted on a robotic…

Vision-Guided Forecasting -- Visual Context for Multi-Horizon Time Series Forecasting

Eitan Kosman, Dotan Di Castro

Autonomous driving gained huge traction in recent years, due to its potential to change the way we commute. Much effort has been put into trying to estimate the state of a vehicle.…

SOLO: Search Online, Learn Offline for Combinatorial Optimization Problems

Joel Oren, Chana Ross, Maksym Lefarov +5

We study combinatorial problems with real world applications such as machine scheduling, routing, and assignment. We propose a method that combines Reinforcement Learning (RL) and…

InsertionNet -- A Scalable Solution for Insertion

Oren Spector, Dotan Di Castro

Complicated assembly processes can be described as a sequence of two main activities: grasping and insertion. While general grasping solutions are common in industry, insertion is…

Depth Completion with RGB Prior

Yuri Feldman, Yoel Shapiro, Dotan Di Castro

Depth cameras are a prominent perception system for robotics, especially when operating in natural unstructured environments. Industrial applications, however, typically involve re…

Practical Risk Measures in Reinforcement Learning

Dotan Di Castro, Joel Oren, Shie Mannor

Practical application of Reinforcement Learning (RL) often involves risk considerations. We study a generalized approximation scheme for risk measures, based on Monte-Carlo simulat…

One-Shot Session Recommendation Systems with Combinatorial Items

Yahel David, Dotan Di Castro, Zohar Karnin

In recent years, content recommendation systems in large websites (or \emph{content providers}) capture an increased focus. While the type of content varies, e.g.\ movies, articles…

Contextual Markov Decision Processes

Assaf Hallak, Dotan Di Castro, Shie Mannor

We consider a planning problem where the dynamics and rewards of the environment depend on a hidden static parameter referred to as the context. The objective is to learn a strateg…

Policy Evaluation with Variance Related Risk Criteria in Markov Decision Processes

Aviv Tamar, Dotan Di Castro, Shie Mannor

In this paper we extend temporal difference policy evaluation algorithms to performance criteria that include the variance of the cumulative reward. Such criteria are useful for ri…

Policy Gradients with Variance Related Risk Criteria

Dotan Di Castro, Aviv Tamar, Shie Mannor

Managing risk in dynamic decision problems is of cardinal importance in many fields such as finance and process control. The most common approach to defining risk is through variou…

Bandits with an Edge

Dotan Di Castro, Claudio Gentile, Shie Mannor

We consider a bandit problem over a graph where the rewards are not directly observed. Instead, the decision maker can compare two nodes and receive (stochastic) information pertai…

A Maximal Large Deviation Inequality for Sub-Gaussian Variables

Dotan Di Castro, Claudio Gentile, Shie Mannor

In this short note we prove a maximal concentration lemma for sub-Gaussian random variables stating that for independent sub-Gaussian random variables we have \[P<(\max_{1\le i\le…

Adaptive Bases for Reinforcement Learning

Dotan Di Castro, Shie Mannor

We consider the problem of reinforcement learning using function approximation, where the approximating basis can change dynamically while interacting with the environment. A motiv…
