H.264 video encoding tools and the development of efficient hardware architectures
Universidade Federal do Rio Grande do Sul –
The H.264/AVC (Advanced Video Coder) or MPEG-4 part 10, is the current state-of-the-art in video coding, providing the highest compression ratios achievable by an internationally standardized video coder (ISO/IEC and ITU-T). These compression capabilities are achieved by a well refined set of coding tools. However further improvements were required and H.264 has already been revised twice to provide new profiles for fidelity extension and professional applications in 2005 and scalability support (H.264/SVC – Scalable Video Coder) in 2007. A third revision under development by JVT (Joint Video Team) aim to support video sources with multiple views (H.264/MVC – Multi-view Video Coder). This lecture presents an overview of the coding tools used by the H.264/AVC and some algorithmic optimizations developed by the UFRGS (Brazil) team toward hardware architecture development for real-time high-definition encoders and decoders.

The 13th Lisbon Machine Learning School | LxMLS 2023
The Lisbon Machine Learning Summer School (LxMLS) takes place yearly at Instituto Superior Técnico (IST). LxMLS 2023 will be a 6-day event (14-20 July, 2023), scheduled to take place as an in-person event.
The school covers a range of machine learning topics, from theory to practice, that are important in solving natural language processing problems arising in different application areas. It is organized jointly by Instituto Superior Técnico (IST), a leading Engineering and Science school in Portugal, the Instituto de Telecomunicações, the Instituto de Engenharia de Sistemas e Computadores, Investigação e Desenvolvimento em Lisboa (INESC-ID), the Lisbon ELLIS Unit for Learning and Intelligent Systems (LUMLIS), Unbabel, Zendesk, and IBM Research.
Check online for information about past editions: LxMLS 2011, LxMLS 2012, LxMLS 2013, LxMLS 2014, LxMLS 2015, LxMLS 2016, LxMLS 2017, LxMLS 2018, LxMLS 2019, LxMLS 2020, LxMLS 2021, LxMLS 2022 (you can also watch the videos of the lectures for 2016, 2017, 2018, and 2020).
31st International Conference on Information Systems Development (ISD 2023)
The 31st International Conference on Information Systems Development (ISD 2023) conference provides a forum for research and developments in the field of information systems. The theme of ISD 2023 is “Information systems development, organizational aspects and societal trends”. New trends in developing information systems emphasize the continuous collaboration between developers and operators in order to optimize the software delivery time. The conference promotes research on methodological and technological issues and how IS developers and operators are transforming organizations and society through information systems.
The ISD 2023 conference held this year also provides an opportunity for researchers and practitioners to promote their research, practical experience, and to discuss issues related to Information Systems through papers, posters, and journal-first paper presentations.
ISD 2023 will be hosted by Instituto Superior Técnico, in Lisbon, Portugal, on August 30–September 1, 2023.
