Robot Task Planning and Situation Handling in Open Worlds

no code implementations4 Oct 2022 Yan Ding, Xiaohan Zhang, Saeid Amiri, Nieqing Cao, Hao Yang, Chad Esselink, Shiqi Zhang

This paper introduces a novel algorithm (COWP) for open-world task planning and situation handling that dynamically augments the robot's action knowledge with task-oriented common sense.

Reasoning with Scene Graphs for Robot Planning under Partial Observability

no code implementations21 Feb 2022 Saeid Amiri, Kishan Chandan, Shiqi Zhang

Robot planning in partially observable domains is difficult, because a robot needs to estimate the current state and plan actions at the same time.

Guiding Robot Exploration in Reinforcement Learning via Automated Planning

no code implementations23 Apr 2020 Yohei Hayamizu, Saeid Amiri, Kishan Chandan, Keiki Takadama, Shiqi Zhang

Reinforcement learning (RL) enables an agent to learn from trial-and-error experiences toward achieving long-term goals; automated planning aims to compute plans for accomplishing tasks using action knowledge.

Learning and Reasoning for Robot Sequential Decision Making under Uncertainty

no code implementations16 Jan 2019 Saeid Amiri, Mohammad Shokrolah Shirazi, Shiqi Zhang

The key contribution of this work is a robot SDM framework, called LCORPP, that supports the simultaneous capabilities of supervised learning for passive state estimation, automated reasoning with declarative human knowledge, and planning under uncertainty toward achieving long-term goals.

Clustering categorical data via ensembling dissimilarity matrices

no code implementations26 Jun 2015 Saeid Amiri, Bertrand Clarke, Jennifer Clarke

Our method extends to high dimensional categorical data of equal lengths by ensembling over many choices of explanatory variables.

A General Hybrid Clustering Technique

no code implementations4 Mar 2015 Saeid Amiri, Bertrand Clarke, Jennifer Clarke, Hoyt A. Koepke

For a given desired number of clusters $K$, we use three stages to find a clustering.
