Abstract

In many applications, synchronizing audio with visuals is crucial, such as in creating graphic animations for films or games, translating movie audio into different languages, and developing metaverse applications. This review explores various methodologies for achieving realistic facial animations from audio inputs, highlighting generative and adaptive models. Addressing challenges like model training costs, dataset availability, and silent moment distributions in audio data, it presents innovative solutions to enhance performance and realism. The research also introduces a new taxonomy to categorize audio-visual synchronization methods based on logistical aspects, advancing the capabilities of virtual assistants, gaming, and interactive digital media.

7. 2-Cats: 2D Copula Approximating Transforms

Author

Figueiredo, Flavio, Fernandes, José Geraldo, Silva, Jackson, and Assunção, Renato M.

Abstract

Copulas are powerful statistical tools for capturing dependencies across data dimensions. Applying Copulas involves estimating independent marginals, a straightforward task, followed by the much more challenging task of determining a single copulating function, $C$, that links these marginals. For bivariate data, a copula takes the form of a two-increasing function $C: (u,v)\in \mathbb{I}^2 \rightarrow \mathbb{I}$, where $\mathbb{I} = [0, 1]$. This paper proposes 2-Cats, a Neural Network (NN) model that learns two-dimensional Copulas without relying on specific Copula families (e.g., Archimedean). Furthermore, via both theoretical properties of the model and a Lagrangian training approach, we show that 2-Cats meets the desiderata of Copula properties. Moreover, inspired by the literature on Physics-Informed Neural Networks and Sobolev Training, we further extend our training strategy to learn not only the output of a Copula but also its derivatives. Our proposed method exhibits superior performance compared to the state-of-the-art across various datasets while respecting (provably for most and approximately for a single other) properties of C.

12. Identifying and Extracting Football Features from Real-World Media Sources using Only Synthetic Training Data

Author

Fernandes, Jose Cerqueira and Kenwright, Benjamin

Abstract

Real-world images used for training machine learning algorithms are often unstructured and inconsistent. The process of analysing and tagging these images can be costly and error prone (also availability, gaps and legal conundrums). However, as we demonstrate in this article, the potential to generate accurate graphical images that are indistinguishable from real-world sources has a multitude of benefits in machine learning paradigms. One such example of this is football data from broadcast services (television and other streaming media sources). The football games are usually recorded from multiple sources (cameras and phones) and resolutions, not to mention, occlusion of visual details and other artefacts (like blurring, weathering and lighting conditions) which make it difficult to accurately identify features. We demonstrate an approach which is able to overcome these limitations using generated tagged and structured images. The generated images are able to simulate a variety views and conditions (including noise and blurring) which may only occur sporadically in real-world data and make it difficult for machine learning algorithm to 'cope' with these unforeseen problems in real-data. This approach enables us to rapidly train and prepare a robust solution that accurately extracts features (e.g., spacial locations, markers on the pitch, player positions, ball location and camera FOV) from real-world football match sources for analytical purposes.

43. Social Entrepreneurial Intention: Educating, Experiencing and Believing

Author

Sousa-Filho, José Milton de, Granados, Maria L., and Lacerda Fernandes, José Augusto

Abstract

With current social, environmental and economic challenges, there is an increasing need to encourage more sustainable business models, which include social entrepreneurship, in the education of our future leaders and entrepreneurs. This has resulted in significant research and practice towards improving students' social entrepreneurial intention with higher education programmes. We used survey data collected from 220 university students in Brazil. These students participated in the Enactus programme, which exposed them to social entrepreneurial experience and entrepreneurial education. Our findings highlight the importance of experience-based programmes in forming empathy, essential to self-efficacy development, and in improving the ability to identify social opportunities, which together are indispensable for developing social entrepreneurial intentions. This paper contributes to social entrepreneurship education literature by emphasising the need to integrate experience-based opportunities into higher education programmes. It confirms that social entrepreneurial actions are contextually driven and should be addressed and developed closer to the needs. This results in empathic individuals who can see opportunities others do not see and become social entrepreneurs. In regard to public policy support and the encouragement of social entrepreneurship models, our findings emphasise the need to help universities and encourage experiential programmes to develop students. In this way, universities which develop social entrepreneurship education programmes have the opportunity to act as agents of change, developing human capital to address the social/environmental challenges and create a fairer society.
