Self-organizing maps of symbol strings
T Kohonen, P Somervuo - Neurocomputing, 1998 - Elsevier
Unsupervised self-organizing maps (SOMs), as well as supervised learning by Learning

How to make large self-organizing maps for nonvectorial data
T Kohonen, P Somervuo - Neural networks, 2002 - Elsevier
The self-organizing map (SOM) represents an open set of input samples by a topologically
organized, finite set of models. In this paper, a new version of the SOM is used for the …

Parametric representations of bird sounds for automatic species recognition
P Somervuo, A Harma… - IEEE Transactions on …, 2006 - ieeexplore.ieee.org
This paper is related to the development of signal processing techniques for automatic
recognition of bird species. Three different parametric representations are compared. The first …

[HTML][HTML] The Glanville fritillary genome retains an ancient karyotype and reveals selective chromosomal fusions in Lepidoptera
Previous studies have reported that chromosome synteny in Lepidoptera has been well
conserved, yet the number of haploid chromosomes varies widely from 5 to 223. Here we report …

Arabidopsis NAC45/86 direct sieve element morphogenesis culminating in enucleation
Photoassimilates such as sugars are transported through phloem sieve element cells in
plants. Adapted for effective transport, sieve elements develop as enucleated living cells. We …

Self-organizing maps and learning vector quantization for feature sequences
P Somervuo, T Kohonen - Neural Processing Letters, 1999 - Springer
The Self-Organizing Map (SOM) and Learning Vector Quantization (LVQ) algorithms are
constructed in this work for variable-length and warped feature sequences. The novelty is to …

[HTML][HTML] High resolution DNA barcode library for European butterflies reveals continental patterns of mitochondrial genetic diversity
The study of global biodiversity will greatly benefit from access to comprehensive DNA barcode
libraries at continental scale, but such datasets are still very rare. Here, we assemble the …

Fungal communities decline with urbanization—more in air than in soil
Increasing evidence suggests that degradation of biodiversity in human populated areas is
a threat for the ecosystem processes that are relevant for human well-being. Fungi are a …

Unbiased probabilistic taxonomic classification for DNA barcoding
P Somervuo, S Koskela, J Pennanen… - …, 2016 - academic.oup.com
Motivation: When targeted to a barcoding region, high-throughput sequencing can be used
to identify species or operational taxonomical units from environmental samples, and thus to …

A molecular‐based identification resource for the arthropods of Finland
To associate specimens identified by molecular characters to other biological knowledge,
we need reference sequences annotated by Linnaean taxonomy. In this study, we (1) report …
