Decision Predicate Graphs: Enhancing Interpretability in Tree Ensembles

no code implementations3 Apr 2024 Leonardo Arrighi, Luca Pennella, Gabriel Marques Tavares, Sylvio Barbon Junior

In addressing this challenge, especially in complex scenarios, we introduce the Decision Predicate Graph (DPG) as a model-agnostic tool to provide a global interpretation of the model.

Tailoring Machine Learning for Process Mining

no code implementations17 Jun 2023 Paolo Ceravolo, Sylvio Barbon Junior, Ernesto Damiani, Wil van der Aalst

Machine learning models are routinely integrated into process mining pipelines to carry out tasks like data transformation, noise reduction, anomaly detection, classification, and prediction.

Anomaly Detection

CoSMo: a Framework to Instantiate Conditioned Process Simulation Models

1 code implementation31 Mar 2023 Rafael S. Oyamada, Gabriel M. Tavares, Sylvio Barbon Junior, Paolo Ceravolo

This architecture facilitates the simulation of event logs that adhere to specific constraints by incorporating declarative-based rules into the learning phase as an attempt to fill the gap of incorporating information into deep learning models to perform what-if analysis.

Rethinking Default Values: a Low Cost and Efficient Strategy to Define Hyperparameters

no code implementations31 Jul 2020 Rafael Gomes Mantovani, André Luis Debiaso Rossi, Edesio Alcobaça, Jadson Castro Gertrudes, Sylvio Barbon Junior, André Carlos Ponce de Leon Ferreira de Carvalho

Our approach is grounded on a small set of optimized values able to obtain predictive performance values better than default settings provided by popular tools.

Strict Very Fast Decision Tree: a memory conservative algorithm for data stream mining

1 code implementation16 May 2018 Victor Guilherme Turrisi da Costa, André Carlos Ponce de Leon Ferreira de Carvalho, Sylvio Barbon Junior

Thus, SVFDT is a suitable option for data stream mining with memory and time limitations, recommended as a weak learner in ensemble-based solutions.
