Matthijs Douze
Matthijs Douze has been a research scientist at the Facebook AI Research (FAIR) lab in Paris since November 2015. At Facebook he is working on large-scale indexing (see the Faiss library), machine learning with graphs and similarity search on images and videos. He obtained a master’s degree from the ENSEEIHT engineering school and defended his PhD at University of Toulouse in 2004. From 2005-2015 Matthijs joined the LEAR team at INRIA Grenoble where he worked on a variety of topics, including image indexing, large-scale vector indexing, event recognition in videos and similar video search. Between 2010 and 2015 he also managed Kinovis, a large 3D motion capture studio at INRIA and developed high-performance geometric algorithms for constructive solid geometry operations. In addition to FAIR’s general research topics, Matthijs is interested in snappy algorithms that process images and produce graphical results.

Lead2Gold: Towards exploiting the full potential of noisy transcriptions for speech recognition
The transcriptions used to train an Automatic Speech Recognition (ASR) system may contain errors. Usually, either a quality control stage discards transcriptions with too many errors, or the noisy transcriptions are used as is. We introduce…

Fixing the train-test resolution discrepancy
Data-augmentation is key to the training of neural networks for image classification. This paper first shows that existing augmentations induce a significant discrepancy between the size of the objects seen by the classifier at train and test…

Deep Clustering for Unsupervised Learning of Visual Features
Clustering is a class of unsupervised learning methods that has been extensively applied and studied in computer vision. Little work has been done to adapt it to the end-to-end training of visual features on large scale datasets. In this work, we present DeepCluster, a clustering method that jointly learns the parameters of a neural network and the cluster assignments of the resulting…
