A Successful Crowdsourcing Approach for Bird Sound Classification
2023
Automated recorders are increasingly used in remote sensing of wildlife, yet automated methods of processing the audio remains challenging. Identifying animal sounds with machine learning provides a solution, but optimizing the models requires annotated training data. Producing such data can require much manual effort, which could be alleviated by engaging masses to contribute to research and share the workload. Birdwatchers are experts on identifying bird vocalizations and form an ideal focal audience for a citizen science project aiming for the required multitudes of annotated avian audio data. For this purpose, we launched a web portal that was targeted and advertised to Finnish birdwatc…
Domain‐specific neural networks improve automated bird sound recognition already with small amount of local data
2022
1. An automatic bird sound recognition system is a useful tool for collecting data of different bird species for ecological analysis. Together with autonomous recording units (ARUs), such a system provides a possibility to collect bird observations on a scale that no human observer could ever match. During the last decades, progress has been made in the field of automatic bird sound recognition, but recognizing bird species from untargeted soundscape recordings remains a challenge. 2. In this article, we demonstrate the workflow for building a global identification model and adjusting it to perform well on the data of autonomous recorders from a specific region. We show how data augmentatio…

Discrimination of serial auditory patterns in rats : roles of configural and elemental associations
2011
In order to test whether rats could discriminate between tone sequences, food deprived rats were given appetitive discrimination conditioning with repeated ascending or descending series of musical notes serving as conditioned stimuli (CSs). The other type of tone sequence was reinforced as the other was followed by nothing. In Experiment 1, each series of 8 tones formed a 2 s cycle. The cycle was repeated six times so that the duration of the whole sequence was 12 s. In Experiment 2, the CSs were similar to those in Experiment 1 except that they started with a random note. As a result, rats could discriminate between the stimuli when the CS started systematically with the same note. When t…

Bayesian semiparametric long memory models for discretized event data
2020
We introduce a new class of semiparametric latent variable models for long memory discretized event data. The proposed methodology is motivated by a study of bird vocalizations in the Amazon rain forest; the timings of vocalizations exhibit self-similarity and long range dependence. This rules out Poisson process based models where the rate function itself is not long range dependent. The proposed class of FRActional Probit (FRAP) models is based on thresholding, a latent process. This latent process is modeled by a smooth Gaussian process and a fractional Brownian motion by assuming an additive structure. We develop a Bayesian approach to inference using Markov chain Monte Carlo and show g…
"Sanoilla puetut" : maahanmuuttajamenestyjien representointi mediassa
2016
Tutkin kandidaatintutkielmassani maahanmuuttajamenestyjien representaatiota Ylen ja Helsingin Sanomien teksteissä. Maahanmuuttajamenestyjä on määritelty tässä tutkimuksessa henkilöksi, jonka menestys rakentuu median välittämän representaation kautta siten, että hän kuvautuu menestyjäksi esimerkiksi työnsä tai lahjakkuutensa vuoksi. Media uutisoi maahanmuuttajista toistuvasti, mutta uutisointi keskittyy ensisijaisesti pakolaisiin. Uutisointi on myös usein ongelmakeskeistä. Maahanmuuttajiin kuuluu kuitenkin muitakin kuin pakolaisia, joten tutkin sen vuoksi maahanmuuttajamenestyjiä. Median asema on yhteiskunnallisena vaikuttajana merkittävä, joten median rakentama kuva maahanmuuttajista on myö…
Dialogisuuden toteutuminen ja asiakkaan äänen kuulluksi tuleminen masennuksen pariterapiassa
2012
Tämän pro gradu -tutkielman tavoitteena oli tarkastella dialogisuuden toteutumista ja masentuneen asiakkaan äänen kuulluksi tulemista pariterapiassa. Lisäksi vertailimme, erosivatko terapeuttien vastaustavat niiden istuntojen välillä, jotka masentunut asiakas oli arvioinut kuulluksi tulemisen suhteen hyviksi ja huonoiksi. Tutkielma on osa Jyväskylän yliopiston psykologian laitoksen Dialogiset ja narratiiviset prosessit masennuksen pariterapiassa -projektia (DINADEP), ja aineistonamme oli projektin yhden pariskunnan terapiaprosessi, joka oli tulokseton. Analysoimme terapeuttien vastaamista masentuneelle asiakkaalle laadullisella monitoimijaisen dialogin tutkimusmenetelmällä (Dialogical Metho…
