mdendro: An R package for extended agglomerative hierarchical clustering

no code implementations23 Sep 2023 Alberto Fernández, Sergio Gómez

"mdendro" is an R package that provides a comprehensive collection of linkage methods for agglomerative hierarchical clustering on a matrix of proximity data (distances or similarities), returning a multifurcated dendrogram or multidendrogram.

Emergence of spatial transitions in urban congestion dynamics

no code implementations8 Mar 2021 Aniello Lampo, Javier Borge-Holthoefer, Sergio Gómez, Albert Solé-Ribalta

The analysis of a large amount of real road networks in previous works showed that congestion points experience spatial abrupt transitions, namely they shift away from the city center as larger urban areas are incorporated.

RL Unplugged: A Collection of Benchmarks for Offline Reinforcement Learning

1 code implementation NeurIPS 2020 Caglar Gulcehre, Ziyu Wang, Alexander Novikov, Thomas Paine, Sergio Gómez, Konrad Zolna, Rishabh Agarwal, Josh S. Merel, Daniel J. Mankowitz, Cosmin Paduraru, Gabriel Dulac-Arnold, Jerry Li, Mohammad Norouzi, Matthew Hoffman, Nicolas Heess, Nando de Freitas

We hope that our suite of benchmarks will increase the reproducibility of experiments and make it possible to study challenging tasks with a limited computational budget, thus making RL research both more systematic and more accessible across the community.

Versatile linkage: a family of space-conserving strategies for agglomerative hierarchical clustering

1 code implementation21 Jun 2019 Alberto Fernández, Sergio Gómez

Agglomerative hierarchical clustering can be implemented with several strategies that differ in the way elements of a collection are grouped together to build a hierarchy of clusters.


Approximate Hubel-Wiesel Modules and the Data Structures of Neural Computation

no code implementations28 Dec 2015 Joel Z. Leibo, Julien Cornebise, Sergio Gómez, Demis Hassabis

This paper describes a framework for modeling the interface between perception and memory on the algorithmic level of analysis.


Benchmark model to assess community structure in evolving networks

1 code implementation23 Jan 2015 Clara Granell, Richard K. Darst, Alex Arenas, Santo Fortunato, Sergio Gómez

In them, the time evolution consists of a periodic oscillation of the system's structure between configurations with built-in community structure.
