Power-Aware Collective Tree Exploration [chapter]

Miroslaw Dynia, Miroslaw Korzeniowski, Christian Schindelhauer
2006 Lecture Notes in Computer Science  
From the 2-approximation algorithm we develop a fast 8-competitive online algorithm, which does not require a previous knowledge of the tree and collects information during the exploration.  ...  An n-node tree has to be explored by a group of k mobile robots deployed initially at the root. Robots traverse the edges of the tree until all nodes are visited.  ...  Profits from a collective exploration of trees are investigated in [2] .  ...

An SE-tree based Characterization of the Induction Problem [chapter]

Ron Rymon
1993 Machine Learning Proceedings 1993  
In this paper we propose a new structure, called SE-tree, as a more general alternative.  ...  Many induction programs use decision trees both as the basis for their search, and as a representation of their classi er solution.  ...  Acknowledgements The idea of using the SE-trees to learn rules originated at a talk by T om Mitchell | I thank him for that, as well as for later suggestions.  ...

Qualitative organization of collections of shapes via quartet analysis

Shi-Sheng Huang, Ariel Shamir, Chao-Hui Shen, Hao Zhang, Alla Sheffer, Shi-Min Hu, Daniel Cohen-Or
2013 ACM Transactions on Graphics  
Abstract We present a method for organizing a heterogeneous collection of 3D shapes for overview and exploration.  ...  We further introduce the concept of degree of separation chart for every shape in the collection and show the effectiveness of using it for interactive shapes exploration.  ...  Interactive Exploration of Shape Collection The organization of a collection of shapes into a C-tree allows fast and intuitive exploration.  ...

The snake-flies (Neuropteroidea: Raphidioptera) of Lublin agglomeration

Wojciech Czarniawski, Rafał Gosik
2008 Annales UMCS Biologia  
In effect 62 specimens of snake-flies, belonging to 5 species were collected, using such methods as an entomological scoop, entomological umbrella, sticky traps and collecting by "picking out."  ...  Total number of 908 sticky traps has been explored. Despite this method, 51 specimens -82% of all collected have been caught.  ...  CONCLUSIONS Although the investigations, presented in these publications, did not concentrate on collecting of snake-flies only, the small number of collected insects during intensive exploration, confirms  ...

Structuring collections with Scatter/Gather extensions

Omar Alonso, Justin Talbot
2008 Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '08  
Previous work has shown the Scatter/Gather model to be useful in exploratory activities that occur when users encounter unknown document collections.  ...  The main extension is the addition of exposed hierarchical tree view that is incrementally built as the user explores the collections. The root node represents the entire document collection.  ...  For this reason we believe it is helpful to explore tools that help users impose their own structure on the document collection while still enabling well-understood exploration techniques.  ...
