Transfer learning can be attributed to several recent breakthroughs in deep learning. It has shown upbeat performance improvements, but most of the transfer learning applications are confined towards fine-tuning. Transfer learning facilitates the learnability of the networks on domains with less data. However, learning becomes a difficult task with complex domains, such as multi-label food recognition, owing to the number of food classes as well as to the fine-grained nature of food images. For this purpose, we will introduce the S2ML-TL, a new transfer learning framework to leverage the knowledge learnt on a simpler single-label food recognition task onto multi-label food recognition. We will show that negative transfer is also related to uncertainty of the classes. After introducing different methods for uncertainty modelling in Deep learning we will show how it can be useful to guide the process of data augmentation and classifier improvement.

What is Common between Negative Transfer, Uncertainty and Food Recognition?

# Welcome everyone to ACL 2022!

The 60th Annual Meeting of the Association for Computational Linguistics is taking place May 22-27, 2022 as a hybrid event, in Dublin and online. We are happy to welcome all of you to this anniversary edition with an almost 50-50 in-person and virtual participation. 
The main conference program features oral presentations, in-person and virtual posters and demo sessions, a plenary session for our best paper presentations and awards, three amazing keynote events and two new initiatives of invited talks: Spotlight Talks for Young Rising Stars (STIRS) and The Next Big Idea Talks. Posters (including Findings of ACL 2022) and demos are grouped by areas for both the in-person and the virtual sessions. For the virtual component, the talks will be on Zoom and the posters and the demos will be in GatherTown. The Student Research Workshop will have an oral session and a poster session as part of Poster Session 1. The program also features eight Tutorials and 28 Workshops. 

 
We wish you a wonderful conference!

ACL 2022

The Association for Computational Linguistics (ACL) is the premier international scientific and professional society for people working on computational problems involving human language, a field often referred to as either computational linguistics or natural language processing (NLP). 

keynote

Deep Learning and Big Data Analytics are two major topics of data science, nowadays. Big Data has become important in practice, as many organizations have been collecting massive amounts of data that can contain useful information for business analysis and decisions, impacting existing and future technology. A key benefit of Deep Learning is the ability to process these data and extract high-level complex abstractions as data representations, making it a valuable tool for Big Data Analytics where raw data is largely unlabeled.
 
Machine-learning and artificial intelligence are pervasive in most real-world applications scenarios such as computer vision, information retrieval and summarization from structured and unstructured multimodal data sources, natural language understanding and translation, and many other application domains. Deep learning approaches, leveraging on big data, are outperforming state-of-the-art more “classical” supervised and unsupervised approaches, directly learning relevant features and data representations without requiring explicit domain knowledge or human feature engineering. These approaches are currently highly important in IoT applications.

An increased number of people face unfavorable mental health conditions at some points in their life, such as depression, stress, and anxiety. The Covid-19 crisis has even reinforced this negative trend. In my talk, I will discuss the potential of modern deep learning techniques to develop a better understanding of mental health conditions. I will describe how to exploit deep learning strategies for developing appropriate intervention strategies, such as personal health care coaches running on the user’s mobile device. Two factors contribute to increased interest in deep learning techniques for mental health promotion. First, the number of affordable mobile and wearable technologies with built-in sensors for quantifying many aspects of our lives is rapidly increasing. Consequently, new data sources and opportunities arise for the development of machine learning models and their applications. Second, deep learning techniques have led to breakthroughs in processing large amounts of data, including multimodal behavioral data and relevant contextual and environmental information. In my talk, I will discuss challenges we need to solve, to implement appropriate solutions for promoting good mental health. Such challenges include the need for lightweight architectures to enable the processing of data on mobile devices, strategies to deal with scarce and noisy data, and the appropriate handling of privacy concerns. Concrete examples from national and international projects, Emma, MindBot, and ForDigitHealth, will illustrate the talk.

Leveraging Deep Learning for Mental Health Promotion

Applications, services and devices using biometric systems are continuously growing, and always new challenges must be faced by researchers. Adaptability, robustness to non-ideal conditions, real-time capability, high accuracy as well as improved interactions with the user, are strong requirements now present in innovative applications and solutions such as cyber security, smart devices and ambient intelligent infrastructures. Biometric systems are designed not just for identity recognition, but they can also be extremely useful to profile users and to understand the human behavior inferring their needs and desires. The presentation will focus on innovative biometric recognition approaches and systems, with specific focus on recent approaches based on artificial intelligence showing how recent deep learning techniques are capable to learn discriminative features directly from complex multidimensional signals and images as well as increasing the accuracy, adaptability, and robustness to non-ideal conditions of biometric systems with respect to traditional approaches. The talk presents biometric systems from a technological point of view and provides an outlook of recent artificial intelligence approaches, including deep learning methods with current strong points and limitations. A review of new applications of biometric systems and recent trends will be also presented.

Deep Learning for Biometric Systems: Applications and Trends

What if, by leveraging the rapid development of AI,cyber-infrastructure, and astronomical surveys we can create an extremely intelligent machine with infinite knowledge that after being feed with all ofthe available survey data from all the sources and wavelengths is able to recreate every observation for any object in any wavelength? What if we can feed that entity with an optical image and ask for a radiocounterpart? Or ask it to generate infrared data from a given set of properties? Will, that machine been able to make inferences from new observations, assuming its infinite memory? Even though this might sound too much science-fiction, 10 to 15 years from now might be an incubating project which needs to start today. In this talk, I'll discuss what efforts have been made in this direction, what deep learning advances might help us think in that future, how data from multiple surveys and telescopes can be combined in taking the first steps, and what have we done to make this happen.Thanks to the advancement of computing, AI, and gateways techniques, the possibilities are countless, and it is now that we need to think about these issues in order to be prepared and to understand how information can be extracted intelligently in favor ofscientific discoveries.
