The document proposes a framework for affective recommender systems that takes into account the role of emotions. The framework models the recommendation process across three stages: entry, consumption, and exit. At the entry stage, the user's mood is detected. Recommendations are then provided to induce a particular affective state during consumption. Finally, at the exit stage the user's mood is again detected and feedback is collected.
Color is one the most important things in our daily life. Guides us, into perceiving a richer world.
This work, shows how color is perceived by humans, and how can we use this information to guide some design decisions.
You will learn how to better use colors in the design of everything, with more scientific knowledge and less subjective opinions.

Deep neural networks have boosted the convergence of multimedia data analytics in a unified framework shared by practitioners in natural language, vision and speech. Image captioning, lip reading or video sonorization are some of the first applications of a new and exciting field of research exploiting the generalization properties of deep neural representation. This tutorial will firstly review the basic neural architectures to encode and decode vision, text and audio, to later review the those models that have successfully translated information across modalities.
CENDOO is your internet butler. CENDOO is based upon this new technology, ai-one™, which provides the ability to think and learn like a biological brain. CENDOO is your automatic service in the background that helps you get things done and does jobs on your behalf. And the more you use CENDOO, the better the service knows your preferences and adapts. In other words, CENDOO knows exactly what you want and does it.
Research in Technology Enhanced Learning is multidisciplinary, what means that several disciplines have to share concepts and methods around a shared objective, and that they have also to coin concepts to take into account the specificity of the questions it addresses. Moreover, having to deal with learning and education, it has to face epistemological and cultural issues due to the history of education and the diversity of the relations to knowledge. As a result TEL research must manage linguistic and semantic issues in a much more critical way than it is the case for computer scientist and specialists of technology involved in this field. To respond to this challenge, the Stellar network of excellence in collaboration with the European association TELEARC, has initiated the creation of a thesaurus and a dictionary of the terms and expressions used in TEL research.

Speech is a rich biometric signal that contains information about the identity, gender and emotional state of the speaker. In this work, we explore its potential to generate face images of a speaker by conditioning a Generative Adversarial Network (GAN) with raw speech input. We propose a deep neural network that is trained from scratch in an end-to-end fashion, generating a face directly from the raw speech waveform without any additional identity information (e.g reference image or one-hot encoding). Our model is trained in a self-supervised fashion by exploiting the audio and visual signals naturally aligned in videos. With the purpose of training from video data, we present a novel dataset collected for this work, with high-quality videos of ten youtubers with notable expressiveness in both the speech and visual signals.

The synchronization of the visual and audio tracks recorded in videos can be used as a supervisory signal for machine learning. This presentation reviews some recent research on this topic exploiting the capabilities of deep neural networks.

Abstract Summary:
Learning About the Brain and Brain-Inspired Learning:
Quantifying mental states and identifying statistical biomarkers of mental disorders from neuroimaging data is an exciting and rapidly growing research area at the intersection of neuroscience and machine learning, with the particular focus on interpretability and reproducibility of learned models. We will discuss promises and limitations of machine-learning methods in such applications, focusing on recent applications of deep learning methods such as recurrent convnets to the analysis of “brain movies” (EEG) data. On the other hand, besides the above “AI to Brain” direction, we will also discuss the “Brain to AI”, namely, borrowing ideas from neuroscience to improve machine learning, with specific focus on adult neurogenesis and online model adaptation in representation learning.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

– ratingPredictions(data-centric descriptors)
= descriptors that are available (e.g. from IMDB)
» Genre
» Actors
» Performers
» Timestamps
– Typical modeling:

From data-centric to user-centric
The data-centric approach is still rooted in the research community:
– It‘s about music, not about recommenders
The community is problem-solving oriented
– The existing datasets are real, why building synthetic ones?
Solving existing problems is only a part of research ...
... the other part is generating new knowledge (on how the world works) ...
... which in turn generates new problems ...
... which in turn opens new publishing possibilities
