WeLa-VAE: Learning Alternative Disentangled Representations Using Weak Labels

no code implementations22 Aug 2020 Vasilis Margonis, Athanasios Davvetas, Iraklis A. Klampanos

Learning disentangled representations without supervision or inductive biases, often leads to non-interpretable or undesirable representations.

Variational Inference

Unsupervised Severe Weather Detection Via Joint Representation Learning Over Textual and Weather Data

no code implementations14 May 2020 Athanasios Davvetas, Iraklis A. Klampanos

When observing a phenomenon, severe cases or anomalies are often characterised by deviation from the expected data distribution.

Clustering Representation Learning

Learning Improved Representations by Transferring Incomplete Evidence Across Heterogeneous Tasks

no code implementations22 Dec 2019 Athanasios Davvetas, Iraklis A. Klampanos

Evidence transfer is a robust solution against external unknown categorical evidence that can introduce noise or uncertainty.

Representation Learning

Evidence Transfer for Improving Clustering Tasks Using External Categorical Evidence

1 code implementation9 Nov 2018 Athanasios Davvetas, Iraklis A. Klampanos, Vangelis Karkaletsis

In this paper we introduce evidence transfer for clustering, a deep learning method that can incrementally manipulate the latent representations of an autoencoder, according to external categorical evidence, in order to improve a clustering outcome.

ANNETT-O: An Ontology for Describing Artificial Neural Network Evaluation, Topology and Training

1 code implementation7 Apr 2018 Iraklis A. Klampanos, Athanasios Davvetas, Antonis Koukourikos, Vangelis Karkaletsis

Deep learning models, while effective and versatile, are becoming increasingly complex, often including multiple overlapping networks of arbitrary depths, multiple objectives and non-intuitive training methodologies.
