Multimodal Generative Models for Bankruptcy Prediction Using Textual Data

no code implementations26 Oct 2022 Rogelio A. Mancisidor, Kjersti Aas

To solve this limitation, this research introduces the Conditional Multimodal Discriminative (CMMD) model that learns multimodal representations that embed information from accounting, market, and textual data modalities.

Using Shapley Values and Variational Autoencoders to Explain Predictive Models with Dependent Mixed Features

1 code implementation26 Nov 2021 Lars Henry Berge Olsen, Ingrid Kristine Glad, Martin Jullum, Kjersti Aas

Shapley values are today extensively used as a model-agnostic explanation framework to explain complex predictive machine learning models.

MCCE: Monte Carlo sampling of realistic counterfactual explanations

1 code implementation18 Nov 2021 Annabelle Redelmeier, Martin Jullum, Kjersti Aas, Anders Løland

We introduce MCCE: Monte Carlo sampling of valid and realistic Counterfactual Explanations for tabular data, a novel counterfactual explanation method that generates on-manifold, actionable and valid counterfactuals by modeling the joint distribution of the mutable features given the immutable features and the decision.

Discriminative Multimodal Learning via Conditional Priors in Generative Models

1 code implementation9 Oct 2021 Rogelio A. Mancisidor, Michael Kampffmeyer, Kjersti Aas, Robert Jenssen

Deep generative models with latent variables have been used lately to learn joint representations and generative processes from multi-modal data.

groupShapley: Efficient prediction explanation with Shapley values for feature groups

no code implementations23 Jun 2021 Martin Jullum, Annabelle Redelmeier, Kjersti Aas

The main drawback with Shapley values, however, is that its computational complexity grows exponentially in the number of input features, making it unfeasible in many real world situations where there could be hundreds or thousands of features.

Explaining predictive models using Shapley values and non-parametric vine copulas

no code implementations12 Feb 2021 Kjersti Aas, Thomas Nagler, Martin Jullum, Anders Løland

In this paper we propose two new approaches for modelling the dependence between the features.

Deep Generative Models for Reject Inference in Credit Scoring

1 code implementation12 Apr 2019 Rogelio A. Mancisidor, Michael Kampffmeyer, Kjersti Aas, Robert Jenssen

Reject inference is the process of attempting to infer the creditworthiness status of the rejected applications.

Learning Latent Representations of Bank Customers With The Variational Autoencoder

no code implementations14 Mar 2019 Rogelio A. Mancisidor, Michael Kampffmeyer, Kjersti Aas, Robert Jenssen

We show that it is possible to steer the latent representations in the latent space of the VAE using the Weight of Evidence and forming a specific grouping of the data that reflects the customers' creditworthiness.

Segment-Based Credit Scoring Using Latent Clusters in the Variational Autoencoder

no code implementations7 Jun 2018 Rogelio Andrade Mancisidor, Michael Kampffmeyer, Kjersti Aas, Robert Jenssen

We use the VAE and show that transforming the input data into a meaningful representation, it is possible to steer configurations in the latent space of the VAE.
