Transfer Learning with Ensembles of Deep Neural Networks for Skin Cancer Detection in Imbalanced Data Sets

no code implementations22 Mar 2021 Aqsa Saeed Qureshi, Teemu Roos

We propose a novel ensemble-based CNN architecture where multiple CNN models, some of which are pre-trained and some are trained only on the data at hand, along with auxiliary data in the form of metadata associated with the input images, are combined using a meta-learner.

A Multilabel Classification Framework for Approximate Nearest Neighbor Search

1 code implementation18 Oct 2019 Ville Hyvönen, Elias Jääsaari, Teemu Roos

Both supervised and unsupervised machine learning algorithms have been used to learn partition-based index structures for approximate nearest neighbor (ANN) search.

Minimum Description Length Revisited

no code implementations21 Aug 2019 Peter Grünwald, Teemu Roos

This is an up-to-date introduction to and overview of the Minimum Description Length (MDL) Principle, a theory of inductive inference that can be applied to general problems in statistics, machine learning and pattern recognition.

Efficient Autotuning of Hyperparameters in Approximate Nearest Neighbor Search

2 code implementations18 Dec 2018 Elias Jääsaari, Ville Hyvönen, Teemu Roos

Therefore, we propose an algorithm for automatically tuning the hyperparameters of indexing methods based on randomized space-partitioning trees.

Learning non-parametric Markov networks with mutual information

1 code implementation8 Aug 2017 Janne Leppä-aho, Santeri Räisänen, Xiao Yang, Teemu Roos

We propose a method for learning Markov network structures for continuous data without invoking any assumptions about the distribution of the variables.

Learning Gaussian Graphical Models With Fractional Marginal Pseudo-likelihood

no code implementations25 Feb 2016 Janne Leppä-aho, Johan Pensar, Teemu Roos, Jukka Corander

We propose a Bayesian approximate inference method for learning the dependence structure of a Gaussian graphical model.

Fast k-NN search

1 code implementation23 Sep 2015 Ville Hyvönen, Teemu Pitkänen, Sotiris Tasoulis, Elias Jääsaari, Risto Tuomainen, Liang Wang, Jukka Corander, Teemu Roos

The method is straightforward to implement using sparse projections which leads to a reduced memory footprint and fast index construction.

Bayesian Properties of Normalized Maximum Likelihood and its Fast Computation

no code implementations28 Jan 2014 Andrew Barron, Teemu Roos, Kazuho Watanabe

The normalized maximized likelihood (NML) provides the minimax regret solution in universal data compression, gambling, and prediction, and it plays an essential role in the minimum description length (MDL) method of statistical modeling and estimation.
