Investigadores de la Universidad de los Andes fueron reconocidos por su proyecto  de dispositivos capaces de leer las emociones a través del reconocimiento de las micro expresiones faciales. El proyecto de telemedicina de investigadores de la Universidad del Norte, que busca construir a través de teléfonos móviles un estetoscopio para diagnosticar condiciones cardiacas en comunidades remotas, también fue uno de los ganadores.

Por quinto año consecutivo, Google anunció los ganadores de los Premios de Investigación de Google para América Latina (LARA, por sus siglas en inglés), entre los que fueron reconocidos dos proyectos colombianos.

El primero de ellos es de los investigadores de la Universidad de los Andes, Pablo Arbeláez y Andrés Romero, que recibieron por tercer año consecutivo un incentivo económico para continuar profundizando su investigación que busca tener dispositivos capaces de entender las emociones de las personas a través del reconocimiento de las microexpresiones faciales.

Por otra parte, por primer vez, dos investigadores de la Universidad del Norte de Barranquilla fueron reconocidos en estos premios; se trata de Winston S. Percybrooks y Pedro Juan Narváez Rosado cuyo proyecto de investigación en telemedicina busca construir a través de teléfonos móviles un estetoscopio de bajo costo, capaz de grabar y  clasificar latidos de corazón y con el uso de aprendizaje automático (machine learning) brindar diagnósticos de condiciones cardiacas en los pacientes, y apoyar atención médica no especializada, especialmente en zonas remotas.

En la ceremonia de premiación, además, se anunciaron otros 25 proyectos de investigación en Ciencias de la Computación que recibirán, durante los próximos dos años, 600 mil dólares para llevar a cabo sus iniciativas. Desde que fueron lanzados los Premios Latin American Research Awards (LARA) en el año 2013, el programa ha beneficiado a 46 proyectos y a más de 100 investigadores, incluyendo estudiantes de maestría y doctorado y sus profesores.

Este año se recibieron 281 proyectos de nueve países de América Latina. Es significativo y muy positivo el crecimiento en el número de investigadores de toda la región enfocados al estudio del aprendizaje automático, un campo que permite enseñar a las computadoras a aprender sin que éstas sean explícitamente programadas. De los 27 proyectos elegidos, 14 se enfocan en aprendizaje automático o Machine Learning.

Por primera vez, el anuncio de los ganadores fue hecho en el Campus São Paulo, un espacio de Google dedicado a los emprendedores. De este modo, la compañía intenta promover una discusión entre los académicos, la comunidad de startupsy directivos de universidades sobre uno de los grandes motores para la innovación en el que la región, tiene amplio espacio para mejorar: el acercamiento entre la academia y la comunidad de emprendedores.

Los ganadores de los Premios LARA 2017 y sus instituciones son:

Adaptive and Personalized Sequential Posted Prices

The goal is to design welfare maximizing mechanisms in an online setting. Such mechanisms should make irrevocable decisions when faced to a customer. Therefore, to achieve good performance, they should incorporate two basic ingredients: personalization meaning that different customers may be treated differently; and adaptivity meaning that the treatment of a customer may depend on the acquired knowledge until that point.

Engineering Compressed Random Access Memories

This proposal aims at creating a layer between programs and the RAM memory they use so that all the stored data is automatically compressed in a way that is transparent to the program. In this way, the actual memory offered by the device is virtually expanded. While such a layer may introduce some performace overhead, we expect it to be much lower than the one introduced by virtual memory systems, which resort to external memory. Further, it can be used in devices with no external memory, like cellphones, sensors, and other low-end devices.

Automated Data­-Driven Screening of Diabetic Retinopathy – Extension

In this research, we aim to design methods to recognize discriminative patterns of diabetic retinopathy stages, providing an advanced and robust severity decision; and incorporate such information into a final higher-level (and more refined) decision of referable DR. We also intend to explore possible forms of understanding the decisions taken by the devised solutions toward accountable decision-making methods.

Learning Dynamic Action Units for Three-dimensional Facial Expression Recognition

Automated understanding of facial expressions is a fundamental step towards high-level human-computer interaction. This project plans to model human facial expressions through the analysis of temporal variations in the pattern of activations of three-dimensional Action Units. The automated facial expression analysis opens the door to multiple application domains beyond emotion classification, such as pain, drowsiness, intoxication, facial unspoken language, depression, or lie detection.

Auditory graphs: conveying data through sound for the visually-impaired

This project’s main goal is to convey quantitative information contained in visual graphs via sound, a technique called sonification, and when particularly applied to graphs, known as auditory graphs. This approach would allow blind or visually-impaired people to access and comprehend this information, otherwise only available in a visual form. This approach has many advantages over the standard method of tactile-graphs, as they are easy to implement with general-purpose computer equipment available today for educational purposes. Of particular interest to us is the development of tools to be used along with widespread web technologies such as images search engines or spreadsheets. We would like to add the capability of not only seeing the data using these tools, but also to hear it.

Multimodal Interaction Environment based on Computer Vision and Robotic Device for Assisting the Diagnosis of Children with Autism Spectrum Disorder

Although there is no cure for autism spectrum disorder (ASD), intensive and early intervention is crucial for increasing child’s level of functioning in daily life. Many research groups are working on technology-based diagnosis and intervention tools for ASD. Nevertheless, the real benefits of their use in systematic clinical practices are still inconclusive. This research aims at developing an open technology-based tool to support clinicians in the diagnosis and therapeutic interventions for children with ASD. A smart room composed of a robotic device and a multi-camera computer vision setup for analyzing the behaviors of children with ASD is currently under development. In this manner, the researchers seek the development of tools to aid clinicians identify risk factors in children with ASD and provide resources for the next-generation of therapeutic interventions. This work is developed by a multidisciplinary team composed of clinical professionals (neuro-pediatricians and psychologists) and experts in biomedical engineering.

Identifying Concept-Drift in Malware Classifiers and the Applicability of Deep-Learning Detectors for APTs

In this project, we intend to develop novel, adaptive models to identify whether a program is benign or malicious during its execution, even when its behavior is subtle, creating a real-time infection detector. We also intend to create a public dataset holding as many features from malicious programs as possible, which will benefit from our proposed techniques to be always up-to-date. The models will rely on deep learning for multi-stage classification, as well as innovative concept-drift detection techniques.
