SM4在被動(dòng)聲學(xué)監(jiān)測(cè)中新熱帶無(wú)尾目鳥(niǎo)類(lèi)識(shí)別基準(zhǔn)數(shù)據(jù)集中的應(yīng)用
Abstract
Global change is predicted to induce shifts in anuran acoustic behavior, which can be studied through passive acoustic monitoring (PAM). Understanding changes in calling behavior requires automatic identification of anuran species, which is challenging due to the particular characteristics of neotropical soundscapes. In this paper, we introduce a large-scale multi-species dataset of anuran amphibians calls recorded by PAM, that comprises 27hours of expert annotations for 42 different species from two Brazilian biomes. We provide open access to the dataset, including the raw recordings, experimental setup code, and a benchmark with a baseline model of the fine-grained categorization problem. Additionally, we highlight the challenges of the dataset to encourage machine learning researchers to solve the problem of anuran call identification towards conservation policy. All our experiments and resources have been made available at https://soundclim.github.io/anuraweb/.
摘要：
全球變化預(yù)計(jì)會(huì)引起無(wú)尾聲波行為的變化，這可以通過(guò)被動(dòng)聲學(xué)監(jiān)測(cè)（PAM）來(lái)研究。了解呼喚行為的變化需要自動(dòng)識(shí)別無(wú)尾目動(dòng)物物種，由于新熱帶音景的特殊特征，這是一個(gè)挑戰(zhàn)。本文介紹了PAM記錄的無(wú)尾兩棲動(dòng)物叫聲的大規(guī)模多物種數(shù)據(jù)集，其中包括來(lái)自巴西兩個(gè)生物群落的42個(gè)不同物種的27小時(shí)專(zhuān)家注釋。我們提供對(duì)數(shù)據(jù)集的開(kāi)放訪問(wèn)，包括原始記錄、實(shí)驗(yàn)設(shè)置代碼和具有細(xì)粒度分類(lèi)問(wèn)題基線模型的基準(zhǔn)。此外，我們強(qiáng)調(diào)了數(shù)據(jù)集的挑戰(zhàn)，以鼓勵(lì)機(jī)器學(xué)習(xí)研究人員解決針對(duì)保護(hù)政策的anuran呼叫識(shí)別問(wèn)題。我們所有的實(shí)驗(yàn)和資源都在https://soundclim.github.io/anuraweb/上面.
