In this paper an information theoretic approach is provided for resolving border ambiguity under partial occlusion. The proposed framework allows structural interpretation of images prior to the application of domain specific knowledge. The central idea behind MDL based figure-ground grouping is merging those place-token candidates whose composed description length (whole) is better than sum of...

This paper describes NAIL, a software system to learn the semantics of language by relating written English commands to actions and properties in a simple 2D ’blocks world’ virtual environment.

Growth codes are a subclass of Rateless codes that have found interesting applications in data dissemination problems. Compared to other Rateless and conventional channel codes, Growth codes show improved intermediate performance which is particularly useful in applications where performance increases with the number of decoded data units. In this paper, we provide a generic analytical framewor...

The ways in which an agent’s actions affect the world can often be modeled compactly using a set of relational probabilistic planning rules. This paper addresses the problem of learning such rule sets for multiple related tasks. We take a hierarchical Bayesian approach, in which the system learns a prior distribution over rule sets. We present a class of prior distributions parameterized by a r...

This paper de nes and addresses the competence and capability assess ment problem A simple method based on the meta knowledge available in a reasoning system is given that can be used to assess competence This idea is applied to the planner ucpop to assess capability in the Blocks World domain Several theoretical and practical problems lead to some experiments that involve generating partial se...

Our work is intended to model and solve artificial planning problems with logic based planning, using the novel semantics called p-stable, which is an alternative of stable semantics. Also we present a method to encode a general planning problem and then we present an example, which is the blocks world problem. This can be applied in a variety of tasks including robotics, process planning, upda...
