The use of Synthetic Data to solve the scalability and data availability problems in Smart City Digital Twins

no code implementations6 Jul 2022 Esteve Almirall, Davide Callegaro, Peter Bruins, Mar Santamaría, Pablo Martínez, Ulises Cortés

However, Digital Twins are data intensive and need highly localized data, making them difficult to scale, particularly to small cities, and with the high cost associated to data collection.

Random Forest as a Tumour Genetic Marker Extractor

no code implementations26 Nov 2019 Raquel Pérez-Arnal, Dario Garcia-Gasulla, David Torrents, Ferran Parés, Ulises Cortés, Jesús Labarta, Eduard Ayguadé

Finding tumour genetic markers is essential to biomedicine due to their relevance for cancer detection and therapy development.

A Visual Distance for WordNet

no code implementations24 Apr 2018 Raquel Pérez-Arnal, Armand Vilalta, Dario Garcia-Gasulla, Ulises Cortés, Eduard Ayguadé, Jesus Labarta

WordNet, which includes a wide variety of concepts associated with words (i. e., synsets), is often used as a source for computing those distances.

Building Graph Representations of Deep Vector Embeddings

no code implementations WS 2017 Dario Garcia-Gasulla, Armand Vilalta, Ferran Parés, Jonatan Moreno, Eduard Ayguadé, Jesus Labarta, Ulises Cortés, Toyotaro Suzumura

Patterns stored within pre-trained deep neural networks compose large and powerful descriptive languages that can be used for many different purposes.

Full-Network Embedding in a Multimodal Embedding Pipeline

no code implementations WS 2017 Armand Vilalta, Dario Garcia-Gasulla, Ferran Parés, Eduard Ayguadé, Jesus Labarta, Ulises Cortés, Toyotaro Suzumura

In this paper we evaluate the impact of using the Full-Network embedding in this setting, replacing the original image representation in a competitive multimodal embedding generation scheme.

An Out-of-the-box Full-network Embedding for Convolutional Neural Networks

no code implementations ICLR 2018 Dario Garcia-Gasulla, Armand Vilalta, Ferran Parés, Jonatan Moreno, Eduard Ayguadé, Jesus Labarta, Ulises Cortés, Toyotaro Suzumura

Transfer learning for feature extraction can be used to exploit deep representations in contexts where there is very few training data, where there are limited computational resources, or when tuning the hyper-parameters needed for training is not an option.

Fluid Communities: A Competitive, Scalable and Diverse Community Detection Algorithm

2 code implementations27 Mar 2017 Ferran Parés, Dario Garcia-Gasulla, Armand Vilalta, Jonatan Moreno, Eduard Ayguadé, Jesús Labarta, Ulises Cortés, Toyotaro Suzumura

We introduce a community detection algorithm (Fluid Communities) based on the idea of fluids interacting in an environment, expanding and contracting as a result of that interaction.

On the Behavior of Convolutional Nets for Feature Extraction

no code implementations3 Mar 2017 Dario Garcia-Gasulla, Ferran Parés, Armand Vilalta, Jonatan Moreno, Eduard Ayguadé, Jesús Labarta, Ulises Cortés, Toyotaro Suzumura

We seek to provide new insights into the behavior of CNN features, particularly the ones from convolutional layers, as this can be relevant for their application to knowledge representation and reasoning.

Limitations and Alternatives for the Evaluation of Large-scale Link Prediction

no code implementations2 Nov 2016 Dario Garcia-Gasulla, Eduard Ayguadé, Jesús Labarta, Ulises Cortés

Link prediction, the problem of identifying missing links among a set of inter-related data entities, is a popular field of research due to its application to graph-like domains.
