• Updating strategies for distance based classification model with recursive least squares 

  Raita-Hakola, Anna-Maria; Pölönen, Ilkka (Copernicus Publications, 2022)

  The idea is to create a self-learning Minimal Learning Machine (MLM) model that is computationally efficient, easy to implement and performs with high accuracy. The study has two hypotheses. Experiment A examines the ...

• Dangerous relationships : biases in freshwater bioassessment based on observed to expected ratios 

  Hämäläinen, Heikki; Aroviita, Jukka; Jyväsjärvi, Jussi; Kärkkäinen, Salme (Ecological Society of America, 2018)

  The ecological assessment of freshwaters is currently primarily based on biological communities and the reference condition approach (RCA). In the RCA, the communities in streams and lakes disturbed by humans are compared ...

• Browning-induced changes in trophic functioning of planktonic food webs in temperate and boreal lakes : insights from fatty acids 

  Strandberg, Ursula; Hiltunen, Minna; Creed, Irena F.; Arts, Michael T.; Kankaala, Paula (Springer, 2023)

  The effects of lake browning on trophic functioning of planktonic food webs are not fully understood. We studied the effects of browning on the response patterns of polyunsaturated fatty acids and n−3/n−6 ratio in seston ...

• Improving Taxonomic Image-based Out-of-distribution Detection With DNA Barcodes 

  Impiö, Mikko; Raitoharju, Jenni (IEEE, 2024)

  Image-based species identification could help scaling biodiversity monitoring to a global scale. Many challenges still need to be solved in order to implement these systems in real-world applications. A reliable image-based ...

• A practical approach to improve the statistical performance of surface water monitoring networks 

  Kotamäki, Niina; Järvinen, Marko; Kauppila, Pirkko; Korpinen, Samuli; Lensu, Anssi; Malve, Olli; Mitikka, Sari; Silander, Jari; Kettunen, Juhani (Springer Netherlands, 2019)

  The representativeness of aquatic ecosystem monitoring and the precision of the assessment results are of high importance when implementing the EU’s Water Framework Directive that aims to secure a good status of waterbodies ...
