Training with Imperfect Transcripts and Language Model Adaptation for ASR of TED talks
L2F/IST and LTI/CMU –
In the first part of this talk, we describe a method that was developed to take advantage of audio with imperfect transcriptions for training acoustic models. Labels that are only approximate, e.g. closed captions, are more common than carefully transcribed speech, and therefore it is useful to be able to take advantage of these types of transcriptions for training. An iterative algorithm is presented that attempts to improve the transcriptions by inserting or removing filler words and pauses, before they are handed to the training process.
In the second part of the talk, we describe an information-retrieval based language model adaptation technique, which is employed to try to improve recognition performance in topic-oriented TED lectures, together with a new technique for implicit language model interpolation.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
