Importance attribution in neural networks by means of persistence landscapes of time series

no code implementations6 Feb 2023 Aina Ferrà, Carles Casacuberta, Oriol Pujol

We propose and implement a method to analyze time series with a neural network using a matrix of area-normalized persistence landscapes obtained through topological data analysis.

A Scalable and Efficient Iterative Method for Copying Machine Learning Classifiers

no code implementations6 Feb 2023 Nahuel Statuto, Irene Unceta, Jordi Nin, Oriol Pujol

Differential replication through copying refers to the process of replicating the decision behavior of a machine learning model using another model that possesses enhanced features and attributes.

Reconstruction of univariate functions from directional persistence diagrams

no code implementations3 Mar 2022 Aina Ferrà, Carles Casacuberta, Oriol Pujol

We describe a method for approximating a single-variable function $f$ using persistence diagrams of sublevel sets of $f$ from height functions in different directions.

Quantile Encoder: Tackling High Cardinality Categorical Features in Regression Problems

2 code implementations27 May 2021 Carlos Mougan, David Masip, Jordi Nin, Oriol Pujol

Regression problems have been widely studied in machinelearning literature resulting in a plethora of regression models and performance measures.

Differential Replication in Machine Learning

no code implementations15 Jul 2020 Irene Unceta, Jordi Nin, Oriol Pujol

When deployed in the wild, machine learning models are usually confronted with data and requirements that constantly vary, either because of changes in the generating distribution or because external constraints change the environment where the model operates.

Sampling Unknown Decision Functions to Build Classifier Copies

no code implementations1 Oct 2019 Irene Unceta, Diego Palacios, Jordi Nin, Oriol Pujol

Copies have been proposed as a viable alternative to endow machine learning models with properties and features that adapt them to changing needs.

Superseding Model Scaling by Penalizing Dead Units and Points with Separation Constraints

no code implementations25 Sep 2019 Carles Riera, Camilo Rey-Torres, Eloi Puertas, Oriol Pujol

Dead points refers to data points that are mapped to zero during the forward pass of the network.

Towards Global Explanations for Credit Risk Scoring

no code implementations19 Nov 2018 Irene Unceta, Jordi Nin, Oriol Pujol

We use a private residential mortgage default dataset as a use case to illustrate the feasibility of this approach to ensure the decomposability of attributes during pre-processing.

Learning to count with deep object features

1 code implementation29 May 2015 Santi Seguí, Oriol Pujol, Jordi Vitrià

Learning to count is a learning strategy that has been recently proposed in the literature for dealing with problems where estimating the number of object instances in a scene is the final objective.

Error-Correcting Factorization

no code implementations27 Feb 2015 Miguel Angel Bautista, Oriol Pujol, Fernando de la Torre, Sergio Escalera

To address these limitations this paper proposes an Error-Correcting Factorization (ECF) method, our contribution is three fold: (I) We propose a novel representation of the error-correction capability, called the design matrix, that enables us to build an ECOC on the basis of allocating correction to pairs of classes.

A Gesture Recognition System for Detecting Behavioral Patterns of ADHD

no code implementations16 Oct 2014 Miguel Ángel Bautista, Antonio Hernández-Vela, Sergio Escalera, Laura Igual, Oriol Pujol, Josep Moya, Verónica Violant, María Teresa Anguera

We propose an extension of DTW using one-class classifiers in order to be able to encode the variability of a gesture category, and thus, perform an alignment between a gesture sample and a gesture class.
