  In this work we describe a hybrid recommendation approach for recommending sounds to users by exploiting and semantically enriching textual information such as tags and sounds descriptions. As a case study we used Freesound, ...
• Freesound technical demo

  Font Corbera, Frederic; Roma, Gerard; Serra, Xavier (ACM Association for Computer Machinery, 2013)

  Freesound is an online collaborative sound database where people with diverse interests share recorded sound samples under Creative Commons licenses. It was started in 2005 and it is being maintained to support diverse ...
• History-based anomaly detector: an adversarial approach to anomaly detection

  Chatillon, Pierrick; Ballester, Coloma (Springer, 2020)

  Anomaly detection is a difficult problem in many areas and has recently been subject to a lot of attention. Classifying unseen data as anomalous is a challenging matter. Latest proposed methods rely on Generative Adversarial ...
• On anisotropic optical flow inpainting algorithms

  Raad, Lara; Oliver Parera, Maria; Ballester, Coloma; Haro Ortega, Gloria; Meinhardt Llopis, Enric (IPOL, 2020)

  This work describes two anisotropic optical flow inpainting algorithms. The first one recovers the missing flow values using the Absolutely Minimizing Lipschitz Extension partial differential equation (also called infinity ...
• Environmental sound recognition using short-time feature aggregation

  Roma Trepat, Gerard; Herrera Boyer, Perfecto, 1964-; Nogueira, Waldo (Springer, 2018)

  Recognition of environmental sound is usually based on two main architectures, depending on whether the model is trained with frame-level features or with aggregated descriptions of acoustic scenes or events. The former ...
• Supporting students in making informed data sharing decisions: from comprehension to consenting

  Beardsley, Marc; Martínez Moreno, Judit; Santos Rodríguez, Patrícia; Hernández Leo, Davinia (Institute of Electrical and Electronics Engineers (IEEE), 2020)

  Whether deciding to participate in a study or gain access to online applications, research suggests that individuals often fail to understand the conditions they agree to when giving consent. Limited comprehension related ...
• Examining university students’ motivation, abilities and preferences related to learning to learn

  Beardsley, Marc; Gutierrez, Nicolas; Hernández Leo, Davinia (Institute of Electrical and Electronics Engineers (IEEE), 2020)

  Learning to learn has been identified as an underdeveloped yet critical skill for learners. However, interventions often struggle to alter learner behavior in a lasting manner. We conducted a quasi-experimental study, ...
• The Challenge of gathering self-reported moods: Cases using a classroom orchestration tool

  Beardsley, Marc; Vujovic, Milica; Theophilou, Emily; Hernández Leo, Davinia; Portero Tresserra, Marta (Institute of Electrical and Electronics Engineers (IEEE), 2020)

  Self-reports of affective states are increasingly being collected in educational settings. However, individual definitions and usage of emotion and mood terms are often subjective despite objective definitions becoming ...
• Individual versus computer-supported collaborative self-explanations: how do their writing analytics differ?

  Albó, Laia; Beardsley, Marc; Amarasinghe, Ishari; Hernández Leo, Davinia (Institute of Electrical and Electronics Engineers (IEEE), 2020)

  Researchers have demonstrated the effectiveness of self-explanations (SE) as an instructional practice and study strategy. However, there is a lack of work studying the characteristics of SE responses prompted by collaborative ...
• Mining arguments in scientific abstracts with discourse-level embeddings
