Half transductive ranking
Jason Weston
Video in druga učna gradiva
Oznake: computer science;information extraction
We study the standard retrieval task of ranking a fixed set of items given a previously unseen query and pose it as the half transductive ranking problem. The task is transductive as the set of items is fixed. Transductive representations (where the vector representation of each example is learned) ...

Large Scale Manifold Transduction
Jason Weston
Video in druga učna gradiva
Oznake:
We show how the regularizer of Transductive Support Vector Machines (TSVM) can be trained by stochastic gradient descent for linear models and multi-layer architectures. The resulting methods can be trained online, have vastly superior training and testing speed to existing TSVM algorithms, can enco ...

Deep Learning via Semi-Supervised Embedding
Jason Weston
Video in druga učna gradiva
Oznake: computer science;machine learning;semi-supervised learning
We show how nonlinear embedding algorithms popular for use with shallow semi-supervised learning techniques such as kernel methods can be applied to deep multi-layer architectures, either as a regularizer at the output layer, or on each layer of the architecture. This provides a simple alternative t ...

Large-Scale Semi-Supervised Learning
Jason Weston
Video in druga učna gradiva
Oznake: computer science;machine learning;semi-supervised learning
Labeling data is expensive, whilst unlabeled data is often abundant and cheap to collect. Semi-supervised learning algorithms that can use both types of data can perform significantly better than supervised algorithms that use labeled data alone. However, for such gains to be observed, the amoun ...

Deep Learning in Natural Language Processing
Ronan Collobert , Jason Weston
Video in druga učna gradiva
Oznake: computer science;natural language processing
This tutorial will describe recent advances in deep learning techniques for Natural Language Processing (NLP). Traditional NLP approaches favour shallow systems, possibly cascaded, with adequate hand-crafted features. In constrast, we are interested in end-to-end architectures: these systems include ...

Large-Scale Clustering through Functional Embedding
Frederic Ratle , Jason Weston , Mathew L. Miller
Video in druga učna gradiva
Oznake: computer science;machine learning;clustering
We present a new framework for large-scale data clustering. The main idea is to modify functional dimensionality reduction techniques to directly optimize over discrete labels using stochastic gradient descent. Compared to methods like spectral clustering our approach solves a single optimization pr ...
