Description of interactive oral story-telling in West African Niger-Congo languages, “orature” contrast to “literature”, has traditionally been firmly the domain anthropological linguistics. The discourse structures narrator-responder interaction and call-response chanted interludes their prosody are an open challenge analysts, linguists phoneticians. Two orature examples from related recorded ...

Many pattern discovery methods provide fast tools for finding the frequently occurring patterns in large data sets. Such pattern collections can also be used to approximate the underlying joint distribution, and they summarize the data set well. However, a large set of patterns is unintuitive and not necessarily easy to use. In this paper we consider the problem of ordering a collection of patt...

In this paper, we address the problem of the eeciency of the main phase of most data mining applications: The frequent pattern extraction. This problem is mainly related to the number of operations required for counting pattern supports in the database, and we propose a new method, called pattern counting inference, that allows to perform as few support counts as possible. Using this method, th...

Data mining research has developed many pattern discovery algorithms dedicated to specific data and pattern characteristics. We argue that a user should not be responsible for choosing the most efficient algorithm to solve a particular data mining problem. Instead, a data mining query optimizer should follow the cost-based optimization techniques to select an appropriate algorithm to solve the ...

Leader election and arbitrary pattern formation are fundammental tasks for a set of autonomous mobile robots. The former consists in distinguishing a unique robot, called the leader. The latter aims in arranging the robots in the plane to form any given pattern. The solvability of both these tasks turns out to be necessary in order to achieve more complex tasks. In this paper, we study the rela...

Given its importance, the problem of object discovery in High-Resolution Remote-Sensing (HRRS) imagery has been given a lot of attention by image retrieval researchers. Despite the vast amount of expert endeavor spent on this problem, more effort has been expected to discover and utilize hidden semantics of images for image retrieval. To this end, in this paper, we exploit a hyperclique pattern...

Protein, RNA and DNA are made up of sequences of amino acids/nucleotides, which interact among themselves via binding. For example, (1) protein-DNA binding regulates gene transcription [1]; and (2) Protein-protein binding plays important roles in cell cycle control and signal transduction [2].The binding is maintained by either the direct participation or assistance of conserved short segments ...

We claim that the core mechanism of a sufficiently general MIR system should be expressed in symbolic terms. We defend the idea that music database should be pre-analyzed before being scanned for MIR queries. We suggest a new vision of automated pattern analysis that generalizes the multiple viewpoint approach by adding a new paradigm based on analogy and temporal approach of musical scores. Th...

We describe algorithms for pattern matching and pattern learning in TOPS diagrams (formal descriptions of protein topologies). These problems can be reduced to checking for subgraph isomorphism and finding maximal common subgraphs in a restricted class of ordered graphs. We have developed a subgraph isomorphism algorithm for ordered graphs, which performs well on the given set of data. The maxi...
