Large Scale Sequence Labelling
Antoine Bordes
Video in druga učna gradiva
Oznake:
The general sequence labelling problem consists in processing an input sequence (xi) and producing an output sequence (yi) of discrete labels. Since the space of the possible output sequences is discrete, this can be viewed as a massive classification problem. \\ The notion of structured output pred ...

LaRank, SGD-QN - Fast Optimizers for Linear SVM
Antoine Bordes
Video in druga učna gradiva
Oznake: computer science;machine learning;kernel methods;support vector machines;optimization methods
Originally proposed for solving multiclass SVM, the LaRank algorithm is a dual coordinate ascent algorithm relying on a randomized exploration inspired by the perceptron algorithm [Bordes05, Bordes07]. This approach is competitive with gradient based optimizers on simple binary and multiclass probl ...

Learning to Disambiguate Natural Language Using World Knowledge
Antoine Bordes
Video in druga učna gradiva
Oznake: computer science;programming languages
We present a general framework and learning algorithm for the task of concept labeling: each word in a given sentence has to be tagged with the unique physical entity (e.g. person, object or location) or abstract concept it refers to. Our method allows both world knowledge and linguistic information ...

Constructing and Mining Web-Scale Knowledge Graphs
Antoine Bordes , Evgeniy Gabrilovich
Video in druga učna gradiva
Oznake: computer science;data mining;knowledge extraction
Recent years have witnessed a proliferation of large-scale knowledge graphs, such as Freebase, YAGO, Facebook’s Open Graph, Google's Knowledge Graph, and Microsoft's Satori. Whereas there is a large body of research on mining homogeneous graphs, this new generation of information networks are highly ...

Sequence Labelling SVMs Trained in One Pass
Antoine Bordes , Nicolas Usunier , Léon Bottou
Video in druga učna gradiva
Oznake:
This paper proposes an online solver of the dual formulation of support vector machines for structured output spaces. We apply it to sequence labelling using the exact and greedy inference schemes. In both cases, the per-sequence training time is the same as a perceptron based on the same inference ...
