| Abstract |
The
last 40 years have seen a dramatic progress in machine
learning for recognizing speech signals and for
translating spoken and written language. This talks will
present a unifying view of the underlying statistical
methods including the recent developments in deep learning
and artificial neural networks. In particular, the talk
will address the remarkable fact that, for these tasks and
similar tasks like handwriting recognition, the
statistical approach makes use of the same four
principles: 1) Bayes decision rule for minimum error rate;
2) probabilistic models like hidden Markov models and
artificial neural networks; 3) training criteria and
algorithms for estimating the free model parameters from
large amounts of data; 4) the generation or search process
that generates the recognition or translation result. Most
of these methods had originally been designed for speech
recognition. However, it has turned out that, with
suitable modifications, the same concepts carry over to
language translation and other tasks in natural language
processing. |
Bio
|
Hermann Ney is a full professor of computer
science at RWTH Aachen University, Germany. His main
research interests lie in the area of statistical
classification, machine learning and human language
technology and specific applications to speech
recognition, machine translation and handwriting
recognition. In particular, he has worked on dynamic
programming and discriminative training for speech
recognition, on language modelling and on phrase-based
approaches to machine translation. His work has resulted
in more than 700 conference and journal papers (h-index
82, estimated using Google scholar). He is a fellow of
both IEEE and ISCA (Int. Speech Communication
Association). In 2005, he was the recipient of the
Technical Achievement Award of the IEEE Signal Processing
Society. In 2010, he was awarded a senior DIGITEO chair at
LIMIS/CNRS in Paris, France. In 2013, he received the
award of honour of the International Association for
Machine Translation. In 2016, he was awarded an ERC
advanced grant. |
