Optimal Decision Tree Synthesis for Efficient Neighborhood Computation
نویسندگان
چکیده
This work proposes a general approach to optimize the time required to perform a choice in a decision support system, with particular reference to image processing tasks with neighborhood analysis. The decisions are encoded in a decision table paradigm that allows multiple equivalent procedures to be performed for the same situation. An automatic synthesis of the optimal decision tree is implemented in order to generate the most efficient order in which conditions should be considered to minimize the computational requirements. To test out approach, the connected component labeling scenario is considered. Results will show the speedup introduced using an automatically built decision system able to efficiently analyze and explore the neighborhood.

Optimal Attribute-Efficient Learning of Disjunction, Parity and Threshold Functions
Decision trees are a very general computation model. Here the problem is to identify a Boolean function f out of a given set of Boolean functions F by asking for the value of f at adaptively chosen inputs. For classes F consisting of functions which may be obtained from one function g on n inputs by replacing arbitrary n?k inputs by given constants this problem is known as attribute-eecient lea...
متن کاملA variable neighborhood search based algorithm for finite-horizon Markov Decision Processes
This paper considers the application of a variable neighborhood search (VNS) algorithm for finite-horizon (H stages) Markov Decision Processes (MDPs), for the purpose of alleviating the ‘‘curse of dimensionality” phenomenon in searching for the global optimum. The main idea behind the VNSMDP algorithm is that, based on the result of the stage just considered, the search for the optimal solution...
متن کاملVariable Neighborhood Search for the Bounded Diameter Minimum Spanning Tree Problem
The bounded diameter minimum spanning tree problem is an NP-hard combinatorial optimization problem with applications in various fields like communication network design. We propose a general variable neighborhood search approach for it, utilizing four different types of neighborhoods. They were designed in a way enabling an efficient incremental evaluation and search for the best neighboring s...
متن کاملSupervisor Synthesis of POMDP based on Automata Learning
As a general and thus popular model for autonomous systems, partially observable Markov decision process (POMDP) can capture uncertainties from different sources like sensing noises, actuation errors, and uncertain environments. However, its comprehensiveness makes the planning and control in POMDP difficult. Traditional POMDP planning problems target to find the optimal policy to maximize the ...
متن کاملNew Graphical Model for Computing Optimistic Decisions in Possibility Theory Framework
This paper first proposes a new graphical model for decision making under uncertainty based on min-based possibilistic networks. A decision problem under uncertainty is described by means of two distinct min-based possibilistic Computing Optimistic Decisions 1039 networks: the first one expresses agent’s knowledge while the second one encodes agent’s preferences representing a qualitative utili...
