Audio processing for diarization and its application to the analysis of primary school courses

The problem of speaker diarization (or just diarization) consists of answering the question «who spoke when?», taking as input an audio signal, which typically has many different speaker voices present on it. In this talk we will briefly introduce the diarization problem and its applications, covering some of the state of the art audio processing algorithms used to tackle it. Finally, we will present the work in progress that is being carried out within a research project between Ceibal and the audio processing group of the Facultad de Ingeniería, UdelaR. In this case, the aim is to adapt the techniques used for diarization to the particular case of teaching analysis in primary school courses. The goal is to develop tools that assist the education technicians who carry out the evaluation and monitoring of different Ceibal educational programs.

Braulio Ríos is an MSc Student in Data Science and Machine Learning at UdelaR, currently working on his thesis about audio processing for diarization and classification, in the context of a research project in collaboration with Ceibal. He has experience working as a developer and consultant for the software industry, mainly in R&D projects with Machine Learning components for the past five years.

Machine learning applied to digital and traditional commerce

We’ll present three case studies illustrating how machine learning can be applied to digital and traditional commerce solutions.

Responsible AI, A Primer

Current advances in Machine Learning and Artificial Intelligence are many and often surprising. So far, such advances have mostly focused on qualitative results (e.g., creating metaheuristic algorithms that can solve complex problems), which generally make users happy. However, the fact that most algorithms produced and used are oblivious of what they are actually performing, and possess little social accountability, somehow are massive shortcomings. In this key speech, I will share some important concepts and questions, as well as ideas and preliminary work being carried out in our research group. These, so that more reasonable, responsible and conscious type of AI could be yielded. None the less, results at this point are not many neither impressive, but the importance of the discussion is deemed to be paramount. Some input from the audience will be highly valued on this multidisciplinary and pressing theme.

Recent Advances in Swarm Intelligence and Swarm Robotics

In the past decades, we witnessed a large improvement of autonomous systems. Today, such systems are everywhere and enable us to handle complex problems in industrial and scientific applications. However, they also pose new challenges for the development of algorithms to design and control them. One challenge concerns the large amount of such systems which are able to communicate with each other and hence produce a large complex system. Looking at nature, biological systems solve complex tasks using decentralized and simple structures. In this talk, we aim to give an overview into such nature-inspired algorithms such swarm intelligence and describe their applications in autonomous systems. Swarm intelligence is a collective learning process which can lead to a self-organized system of simple individuals, which together create a global emergent behavior.

Such systems can adapt very well to changes in the environment and produce flexible and at the same time robust behaviour. One advanced application of swarm intelligence is in the area of swarm robotics in which simple small robots can collectively learn to achieve some predefined complex tasks. In this talk, the algorithms of swarm intelligence are presented, analyzed and compared. The following topics will be covered:

  • Fundamentals of swarm intelligence algorithms and optimization
  • Collective learning and decision-making
  • Collective perception algorithms
  • Control mechanisms for self-organized systems using the environment (isomorphic and non-isomorphic transformations)
  • Swarm and evolutionary robotics

Adaptive Fuzzy Systems in Economics and Finance: Evaluating Interval Forecasts of High-Frequency Data

The forecast of the future movement of economic and financial variables assumes a central role for the composition of portfolios, risk management, asset pricing and investment analysis; therefore, the development of prediction methodologies is of fundamental importance. With the recent and rapid growth in the availability of financial information, especially at intraday frequencies, approaches to forecasting interval time series have gained prominence in the
literature, since they comprise the construction of more informative forecasts, capable of capturing the fluctuations of an asset, index or
rate over the course of a transaction day, as opposed to techniques based on one-off anticipations. Adaptive fuzzy models are nonlinear, are able to update their structure and functionality according to data streams, and handle uncertainty from fuzzy sets. Thus, this approach allows the dynamic treatment of complex phenomena, as well as considering information affected by uncertainties, as is the case of financial markets.

Automatic Algorithm Configuration: Performance, Analysis and Design

Algorithm configuration is the task of finding a set of parameter settings which allow an algorithm to reach an expected performance level. All sorts of algorithms are designed to expose parameters for their later configuration. These postponed design choices grant algorithms flexibility and allow them to be general enough to tackle different problems. The algorithm configuration task is often challenging; finding adequate settings usually requires some level of expert knowledge. From a practical perspective, this task can be tedious and often computationally expensive. In this talk, we will discuss the problem of algorithm configuration, how configurators automate this task and how these techniques can be helpful in understanding algorithms. Automated configuration not only eases algorithm application but also provides a tool that can be used to support automated algorithm design. We will discuss what is required to achieve such a level of automation and the challenges associated with this goal.

Neuroevolution Landscapes and Trajectories

Neuroevolution, the use of evolutionary algorithms to design neural networks, has a long tradition in evolutionary computation with roots in the early 1990s. Traditionally, neuroevolution systems optimize both the neural network topology and its weights. However, when scaling up to contemporary deep models with millions of weights, gradient-based weight optimization generally outperforms evolutionary methods. In consequence, many recent methods evolve the topology only. This approach is also known as Neural Architecture Search (NAS). This talk overviews our recent work on modelling neuroevolution and NAS systems with search trajectory networks (STNs) and local optima networks (LONs) with the aim of providing a visual and quantitative understanding of search and optimisation in this domain.

Using Machine Learning in communication network research

Nowadays, Machine Learning (ML) tools are commonly used in every area of science or technology. Networking is not an exception, and we find ML all over the research activities in most fields composing the domain. In this talk, we will briefly describe a set of research activities we have developed along several years around several pretty different families of problems, using ML methods. They concern:

  1. the automatic and accurate real time measure of the Quality of Experience of an application or service built on top of the Internet around the transport of video or audio content (e.g. video streaming, IP telephony, video-conferencing, etc.),
  2. network tomography (measuring on the edges to infer values inside the network),
  3. time series forecasting in several contexts, in particular concept drift detection or anomalies detection, and
  4. service placements in Software Defined Networks, a central problem in 5G and B5G technologies.

The corresponding ML tools are mainly Supervised Learning and Reinforcement Learning, even if we are currently using Unsupervised Learning in recent activities of point 1. After this global presentation we will make one or two zooms on some specific results we obtained with these powerful tools, and some of the current projects we are currently developing.
