Física estadística de selección y validación de modelos para datos complejos

MINECO (Spain)
102,000€
from June 1, 2020 to May 31, 2023

At least since the scientific revolution, interpretable mathematical models have been instrumental for advancing our understanding of the world. The “big data” era held the promise of facilitating the discovery of similarly interpretable mathematical models of natural and socio-economic systems that were previously not amenable to quantitative analysis. Yet, so far we have not seen such an explosion of new interpretable mathematical models. This is in part because machine learning models a...

Data science of judicial decisions for evidence-based housing policies in Spain

La Caixa Foundation (Spain)
99,950€
from Jan. 1, 2020 to Dec. 31, 2021

Housing the most vulnerable is an explicit societal pillar of the European Union since 2017. In Spain, the lack of reliable sources of housing-related data is causing erratic and contradictory judicial decisions with devastating consequences for hundreds of thousands of families. This project seeks to analyze systematically through data science tens of thousands of housing-related court decisions (such as evictions, abusive clauses, or squatting) before and after the beginning of the housi...

Statistical Mechanics for Modeling and Prediction of Human Behavior

MINECO (Spain)
211,000€
from Jan. 1, 2017 to June 30, 2020

StatMech2Pred is an ambitious project which intends to understand human behavior at individual and society scales by developing new prediction and observational techniques based on statistical mechanics. During the past 15 years we have witnessed a remarkable increase in both the scale and scope of social and behavioral data available. Such wealth of data has not only opened the possibilities to understand social systems in an unprecedented manner but also has also emphasized the need for ...

Problema a resoldre

Extreure valor a partir de l’anàlisis de les dades continua essent, avui més que mai, l’autèntic coll d’ampolla tecnològic vinculat al paradigma Big Data. La facilitat actual a l’hora de generar, transmetre i emmagatzemar grans volums de dades no es correspon amb la capacitat real de tractar i extreure informació d’interès mitjançant l’ús de mètodes d’anàlisis cada cop més sofisticats. Calen doncs mètodes d’anàlisis potents que aportin insight d’interès als propi...

Statistical Mechanics for Big Data: acquisition, analysis and modeling

MINECO (Spain)
90000€
from Jan. 1, 2014 to June 30, 2017

Technological advances during the last fifteen years have boosted our capacity to generate and store data. Indeed, according to some estimates 90% of the world’s stored data has been generated in the last two years, and the availability of such large quantities of data is changing the way we face crisis response, social mobilization, marketing, and intelligence. In science, the hopes created by big data are also high, and analyses of large datasets are behind recent breakthroughs in areas ...

Discovery, decomposition and dynamics of complex networks

James S. McDonnell Foundation (USA)
445,663$
from Jan. 1, 2011 to Dec. 31, 2016

Recent technological advances have boosted our ability to gather information on a variety of complex processes occurring at scales from the cellular to the planetary. At a cellular scale, the number of unicellular organisms whose genome has been completely sequenced has grown exponentially in the last few years. For each of these organisms, we know with remarkable accuracy the exact sequence of nucleotides in their DNA-in other words, we know their bio- chemical "blueprint." Unfortunately,...

Multiplex: Foundational Research on MULTI-level comPLEX networks and systems

FP7 (European Union)
7,861,905€
from Nov. 1, 2012 to Oct. 31, 2016

Many artificial and natural systems are characterized by a high level of differentiation in structure and organization; they exist in areas as diverse as the Internet, energy management, climate, financial markets, infrastructures (including ICT), biology, transport, epidemics, meteorology, urban planning, social simulation and policy impact assessment. In order to describe and control these systems there is a need to observe and reconstruct their dynamics and make sense of large amounts o...

Inferencia estadística para el análisis de perturbaciones sistémicas en redes complejas

MINECO - Europa Excelencia
60,000€
from Nov. 1, 2015 to Oct. 31, 2016

System-wide disturbances that result from seemingly small perturbations are widespread, important and, in general, poorly understood. Consider, for example, how ingestion of a small amount of certain chemicals can trigger systemic physiological changes leading to disease; or how bankruptcy of a few companies can trigger a global economic crisis.

The challenges involved in understanding these processes arise from the properties of the systems in which they take place. Indeed, these s...

Group-based Dynamics on Complex Networks

FP7 (European Union)
100,000€
from March 1, 2011 to Feb. 28, 2015

Cells, ecosystems and economies are examples of complex systems. In complex systems, individual components interact with each other, usually in nonlinear ways, giving rise to complex networks of interactions that are neither totally regular nor totally random. Partly because of the interactions themselves and partly because of the interaction topology, complex systems cannot be properly understood by just analyzing their constituent parts, which poses important challenges from both a funda...

Decomposition and Discovery of Complex Networks

FP7 (European Union)
100,000€
from Sept. 1, 2010 to Aug. 31, 2014

In complex systems, individual components interact with each other often in non-linear ways via a non-trivial network of interactions. The structure of such network of interactions affects that system's dynamics and conveys information about the functional needs of the system, its evolution, and the role of individual units. For these reasons, network analysis has become a cornerstone of fields as diverse as systems biology, economics and sociology. In these fields, the advance of technolo...

Statistical inference for complex network discovery and feature extraction

MINECO (Spain)
45,000€
from Jan. 1, 2010 to June 30, 2014

In complex systems, individual components interact with each other giving rise to complex networks of interactions that are neither totally regular nor totally random. Although during the last decade significant progress has been made in the study of complex networks, we are still far from the ultimate goals of: (i) characterizing real-world complex networks; (ii) understanding the precise mechanisms responsible for the observed topology; and (iii) evaluating the impact of the structure of...
