Functional brain connectivity is a popular technique for investigating neural organization in both healthy subjects and patients with mental illness, and such connectivity is usually measured with functional magnetic resonance imaging (fMRI). Recently, brain-computer interfaces (BCI) based on non-invasive measurements, such as electroencephalography (EEG), are allowing to acquire brain activity related to different mental tasks. It is through the analysis of such EEG measurements that we try to assess the functional brain networks during the different mental tasks. Hence, in this presentation we will review some of the metrics that our laboratory has explored so far in order to make that assessment. In particular, I will mainly talk about the partial directed coherence (PDC), which was recently introduced as a linear frequency-domain quantifier of the multivariate relationship between simultaneously observed EEG data. Therefore, we use the PDC to explain functional connectivitites observed in typical BCI experiments, which are in agreement with those previously observed in fMRI, but with the advantage of having a less elaborated experimental setting.

Spiking neural models and its application in pattern recognition

Dr. Roberto A. Vázquez

Spiking neurons are models designed to simulate, in a realistic manner, the behavior of biological neurons. These models have been called the 3rd generation of artificial neural networks. This kind of models has been applied in a wide range of areas, mainly from the field of computational neurosciences, however, its application in the field of artificial intelligence is practically new. Spiking neurons are neural models that try to simulate the behavior of biological neurons when they are excited with an input current (input pattern) during a certain period time. Instead of generating a response in its output every iteration, as classical neurons do, this model generates a response (spikes or spike train) only when the model reaches a specific threshold. This response could be coded into a firing rate and perform a pattern classification task according to the firing rate generated with the input current. To perform a classification task the model ought to exhibit the next behavior: patterns from the same class must generate similar firing rates and patterns from other classes have to generate firing rates sufficiently dissimilar to differentiate among the classes. In this talk, we describe a methodology for apply a spiking neural model in pattern recognition problems as well as the advantage against classical neural models.

Towards Evidence Based Education and Learning with Learning Analytics

Dr. Hiroaki Ogata
Kyoto University


The multi-disciplinary research approach of Learning Analytics (LA) has provided methods to understand learning logs collected during varied teaching-learning activities and potentially enrich such experiences. This talk will explain how technology can help to extract evidence of effective teaching-learning practices by applying the knowledge base of LA and developing novel techniques. It focuses discussions on realizing a technology-enhanced evidence-based education and learning (TEEL) system. This talk will propose the Learning Evidence Analytics Framework (LEAF) and draw a research road-map of educational big data-driven evidence-based education system. Teachers can refine their instructional practices, learners can enhance learning experiences and researchers can study the dynamics of the teaching-learning process with it.

Decentralized event-triggered leader-following consensus of VTOL-UAVs

Dr. José Fermi Guerrero-Castellanos
Benemérita Universidad Autónoma de Puebla


Motivated by applications in physics, biology and engineering the study of consensus and cooperative control of dynamic systems has become an important topic in engineering and control theory. Roughly speaking, consensus means to reach an agreement regarding a certain quantity of interest that depends on the state of all agents. Recently, published works addressed resource aware implementations of the control law using event-triggered sampling, where the control law is event-driven. Such a paradigm calls for resources whenever they are indeed necessary. In the context of cooperative control (centralized or decentralized), the event-based paradigm appears as a mean to reduce the communication bandwidth in the network since, contrary to the classical scheme, an event-triggered control invokes a communication between the different agents only when a certain condition is satisfied. In this talk one presents the development of an event-based collaborative control applied to the problem of consensus and formation of a group of VTOL-UAVs (Vertical Take-off and Landing, Unmanned Aerial Vehicles). Assuming that the vehicle network exchange information through a directed and strongly connected graph, a decentralized control law is designed, and an event-based algorithm is developed. Each VTOL-UAV decides, based on the difference of its current state and its latest broadcast state, when it has to send a new value to its neighbors. The stability of the complete system is carried out in the Lyapunov sense together with the ISS (Input-to-State Stability) approach. Numerical simulations and real-time experimentations validate the theoretical analysis. Finally, an overview about our work at BUAP in the framework of UAVs will be presented.

From Author to Behavioral Profiling in Social Media

Dr. Manuel Montes y Gómez
Laboratorio de Tecnologias del Lenguaje
Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE)



Everyday the Internet witnesses a great amount of people activity in many different social media sites. They allow us to share –personal– information very easily and with it they offer innumerable new opportunities for business intelligence, health monitoring and personalization of applications. However, at the same time, and as a consequence of the anonymity they provide, they also represent a major threat to users who are exposed to a number of risks and potential attacks.
This talk aims to resume some ideas we have developed in the previous five years towards the profiling of social media users and the detection of some of such attacks. Firstly, it will describe the author profiling task and present a new feature selection and weighting approach especially suited for it. Secondly, it will show the application of this approach for the detection of depressed users. Thirdly, it will present a new representation based on the idea of the emotions flow for the detection of depressed and aggressive users. The talk will conclude with a brief overview of our ongoing work in these tasks.
