The problem of learning metrics between structured data (strings, trees or graphs) has been the subject of various recent papers. With regard to the specific case of trees, some approaches focused on the learning of edit probabilities required to compute a so-called stochastic tree edit distance. However, to reduce the algorithmic and learning constraints,(More)
In this paper, we present SEDiL, a Software for EditDistance Learning. SEDiL is an innovative prototype implementation grouping together most of the state of the art methods [1{4] that aim to automatically learn the parameters of string and tree edit distances. ? This work was funded by the French ANR Marmota project, the Pascal Network of Excellence and(More)
Nowadays, there is a growing interest in machine learning and pattern recognition for tree-structured data. Trees actually provide a suitable structural representation to deal with complex tasks such as web information extraction, RNA secondary structure prediction, computer music, or conversion of semi-structured data (e.g. XML documents). Many(More)
Learning the parameters of the edit distance has been increasingly studied during the past few years to improve the assessment of similarities between structured data, such as strings, trees or graphs. Often based on the optimization of the likelihood of pairs of data, the learned models usually take the form of probabilistic state machines, such as(More)
Alpinia species, used as ornamental plants and flavoring agents, are renowned for their therapeutic properties and their subsequent use in traditional medicines throughout the world. Alpinia zerumbet (Pers.) B.L.Burtt & R.M.Sm. is the most common Alpinia species encountered in Martinique. Several essential oils (EOs) obtained by hydrodistillation of A.(More)
IN HIS RECENT BIOGRAPHY of Jean Genet, Edmund White tells of the dramatist's fascination with the Pope. Genet purportedly revealed to Laurent Boyer, his "executeur testamentaire" at Gallimard, that if ever the Pope invited him to the Vatican, he would accept in a second. The ecclesiastical pomp of the center of power of the Catholic Church intrigued him to(More)
