Seminar on Speech Representations by Santi Pascual WEDNESDAY 25th at 12:15h, Campus Nord, D5-010. UPC - Universitat Politècnica de Catalunya

20 September, 2019

Santi Pascual is going to present his INTERSPEECH paper (nominated at Best Paper Award) about Speech Representations. He is also going to present ongoing progress on the topic. As follows, the title and abstract of the paper.

TITLE: Learning Problem-agnostic Speech Representations from Multiple Self-supervised Tasks

Abstract: Learning good representations without supervision is still an open issue in machine learning, and is particularly challenging for speech signals, which are often characterized by long sequences... Read more

TALP Talk: Conversational agents by Carlos Segura (Telefónica Research)

20 January, 2018

Conversational agents, also known as ChatBots or Dialog Systems, have gained a lot of interest recently. Traditional conversational agent systems usually require significant development effort and are based on complex modules for understanding user inputs, taking decisions and generating meaningful answers. Thanks to the advance of deep learning in close areas such as Neural Machine Translation, recent research is being devoted to data-driven neural conversational models that can learn from human conversations. However, the development of robust and reliable chatbots based purely on deep... Read more

Deep Learning Winter School

09 January, 2018

Introduction to Deep Learning

Winter School at Universitat Politècnica de Catalunya (2018)

Deep learning technologies are at the core of the current revolution in artificial intelligence for multimedia data analysis. The convergence of large-scale annotated datasets and affordable GPU hardware has allowed the training of neural networks for data analysis tasks which were previously addressed with hand-crafted features. Architectures such as convolutional neural networks, recurrent neural networks or Q-... Read more

TALP Talk: Game of Bluemix. Cómo utilizar Watson

28 November, 2017

Bluemix es un entorno de plataforma como servicio desarrollado por IBM. Soporta varios lenguajes de programación y servicios así como la metodología de desarrollo DevOps de forma integrada para crear, ejecutar, desplegar y gestionar aplicaciones en la nube. Bluemix está basado en la tecnología abierta de Cloud Foundry y corre sobre la infraestructura de SoftLayer.

Watson ganó fama mundial cuando ganó en el concurso de televisión Jeopardy en el 2011, e IBM ha estado desarrollando aplicaciones comerciales basadas en inteligencia cognitiva adaptada a la empresa desde entonces.

Title
Document-Level Machine Translation as a Re-translation Process

Speaker
Eva Martínez

Room
Omega-S208 Campus Nord - UPC

Date
To be confirmed

Time
11:00h

Abstract

Most of the current Machine Translation systems are designed to translate a document sentence by sentence ignoring discourse information and producing incoherencies in the final translations. In this paper we present some documentlevel-oriented post-processes to improve translations coherence and consistency. Incoherences... Read more
