Generalization of feature embeddings transferred from different video anomaly detection domains

no code implementations28 Jan 2019 Fernando Pereira dos Santos, Leonardo Sampaio Ferraz Ribeiro, Moacir Antonelli Ponti

By proposing novel cross-domain generalization measures, we study how source features can generalize for different target video domains, as well as analyze unsupervised transfer learning.

SC-GlowTTS: an Efficient Zero-Shot Multi-Speaker Text-To-Speech Model

2 code implementations2 Apr 2021 Edresson Casanova, Christopher Shulby, Eren Gölge, Nicolas Michael Müller, Frederico Santos de Oliveira, Arnaldo Candido Junior, Anderson da Silva Soares, Sandra Maria Aluisio, Moacir Antonelli Ponti

In this paper, we propose SC-GlowTTS: an efficient zero-shot multi-speaker text-to-speech model that improves similarity for speakers unseen during training.

Improving Data Quality with Training Dynamics of Gradient Boosting Decision Trees

1 code implementation20 Oct 2022 Moacir Antonelli Ponti, Lucas de Angelis Oliveira, Mathias Esteban, Valentina Garcia, Juan Martín Román, Luis Argerich

Real world datasets contain incorrectly labeled instances that hamper the performance of the model and, in particular, the ability to generalize out of distribution.

Sketch-an-Anchor: Sub-epoch Fast Model Adaptation for Zero-shot Sketch-based Image Retrieval

no code implementations29 Mar 2023 Leo Sampaio Ferraz Ribeiro, Moacir Antonelli Ponti

Sketch-an-Anchor is a novel method to train state-of-the-art Zero-shot Sketch-based Image Retrieval (ZSSBIR) models in under an epoch.
