  •  AWARD   MERL's Speech Team Achieves World's 2nd Best Performance at the Third CHiME Speech Separation and Recognition Challenge
    Date: December 15, 2015
    Awarded to: John R. Hershey, Takaaki Hori, Jonathan Le Roux and Shinji Watanabe
    MERL Contacts: Takaaki Hori; Jonathan Le Roux
    Research Areas: Multimedia, Speech & Audio
    Brief
    • The results of the third 'CHiME' Speech Separation and Recognition Challenge were publicly announced on December 15 at the IEEE Automatic Speech Recognition and Understanding Workshop (ASRU 2015) held in Scottsdale, Arizona, USA. MERL's Speech and Audio Team, in collaboration with SRI, ranked 2nd out of 26 teams from Europe, Asia and the US. The task this year was to recognize speech recorded using a tablet in real environments such as cafes, buses, or busy streets. Due to the high levels of noise and the distance from the speaker's mouth to the microphones, this is very challenging task, where the baseline system only achieved 33.4% word error rate. The MERL/SRI system featured state-of-the-art techniques including multi-channel front-end, noise-robust feature extraction, and deep learning for speech enhancement, acoustic modeling, and language modeling, leading to a dramatic 73% reduction in word error rate, down to 9.1%. The core of the system has since been released as a new official challenge baseline for the community to use.

  •  NEWS   3D microscopy work of MERL researcher featured in Nature article
    Date: July 23, 2015
    Research Area: Multimedia
    Brief
    • Work by MERL researcher, Ulugbek Kamilov, has been reviewed in the "News & Views” section of Nature. The work, which was part of his doctoral dissertation at EPFL in Lausanne, Switzerland, describes a framework to reconstruct the 3D refractive index of an object by solving a large-scale optimization problem that considers how light propagates through a medium. Results have been shown for 3D imaging of biological cells, but the solution to such inverse problems have the potential to be applied to a much wider set of imaging problems, such as seeing through fog, murky water or even human tissue.

  •  NEWS   Shinji Watanabe publishes new book on Bayesian Speech and Language Processing
    Date: July 15, 2015
    Research Areas: Multimedia, Speech & Audio
    Brief
    • A new book on Bayesian Speech and Language Processing has been published by MERL researcher, Shinji Watanabe, and research collaborator, Jen-Tzung Chien, a professor at National Chiao Tung University in Taiwan.

      With this comprehensive guide you will learn how to apply Bayesian machine learning techniques systematically to solve various problems in speech and language processing. A range of statistical models is detailed, from hidden Markov models to Gaussian mixture models, n-gram models and latent topic models, along with applications including automatic speech recognition, speaker verification, and information retrieval. Approximate Bayesian inferences based on MAP, Evidence, Asymptotic, VB, and MCMC approximations are provided as well as full derivations of calculations, useful notations, formulas, and rules. The authors address the difficulties of straightforward applications and provide detailed examples and case studies to demonstrate how you can successfully use practical Bayesian inference methods to improve the performance of information systems. This is an invaluable resource for students, researchers, and industry practitioners working in machine learning, signal processing, and speech and language processing.

  •  NEWS   John Hershey gives talk at MIT on Deep Unfolding
    Date: April 28, 2015
    Research Area: Multimedia
    Brief
    • MERL researcher and speech team leader, John Hershey, gave a talk at MIT entitled, “Deep Unfolding: Deriving Novel Deep Network Architectures from Model-based Inference Methods” on April 28, 2015.

      Abstract: Model-based methods and deep neural networks have both been tremendously successful paradigms in machine learning. In model-based methods, problem domain knowledge can be built into the constraints of the model, typically at the expense of difficulties during inference. In contrast, deterministic deep neural networks are constructed in such a way that inference is straightforward, but their architectures are rather generic and it can be unclear how to incorporate problem domain knowledge. This work aims to obtain some of the advantages of both approaches. To do so, we start with a model-based approach and unfold the iterations of its inference method to form a layer-wise structure. This results in novel neural-network-like architectures that incorporate our model-based constraints, but can be trained discriminatively to perform fast and accurate inference. This framework allows us to view conventional sigmoid networks as a special case of unfolding Markov random field inference, and leads to other interesting generalizations. We show how it can be applied to other models, such as non-negative matrix factorization, to obtain a new kind of non-negative deep neural network that can be trained using a multiplicative back propagation-style update algorithm. In speech enhancement experiments we show that our approach is competitive with conventional neural networks, while using fewer parameters.
