Weak Label Supervision for Monaural Source Separation Using Non-Negative Denoising Variational Autoencoders
(IEEE, 2019) Karamatli, Ertug; Kirbiz, Serap; Cemgil, Ali Taylan
Deep learning models are very effective in source separation when there are large amounts of labeled data available. However it is not always possible to have carefully labeled datasets. In this paper, we propose a weak supervision method that only uses class information rather than source signals for learning to separate short utterance mixtures. We associate a variational autoencoder (VAE) with each class within a non-negative model. We demonstrate that deep convolutional VAEs provide a prior model to identify complex signals in a sound mixture without having access to any source signal. We show that the separation results are on par with source signal supervision.

Türkiye'nin Döngüsel Ekonomiye Geçiş Performansı Üzerine Karşılaştırmalı bir Analiz
(2024) Asfuroglu, Dila
This study aims to demonstrate Turkey's performance on the transition to the circular economy by comparing it with selected developed and developing economies. The quantitative analysis is conducted with the data collected from Eurostat and the OECD.Stat over the period 2000– 2022, for the selected developed economies, namely, Germany, Sweden, and the United Kingdom, and the selected developing economies, namely, Hungary, Bulgaria, Albania, and Serbia. According to the results, Turkey's resource productivity has increased over the years, with the most effective increases observed since 2017. The relatively low domestic material consumption and material footprint indicate low demand and consumption overall. The increase in total waste per capita with a decrease in municipal waste per capita shows that Turkey's household waste generation is low, but waste generation per person is high. The most frequently used waste treatment has been disposal for ma ny years, yet recycling has accelerated since 2016. The increase in the recycling rate of municipal waste, according to the data that is available for the last five years, is a positive development. Import dependency has not decreased over the years, although it is at lower levels compared to developed countries. In recent years, dependency on all raw materials has been declining, while dependency on metal ores and fossil energy has been very high. Finally, greenhouse gas emissions have increased significantly over the years, making this indicator Turkey's worst for the transition to a circular economy. Since the existing literature has mostly covered European Union (EU) countries and the research on Turkey is generally about creating a theoretical framework, this study fills the gap in the literature. Through country comparisons, this paper also facilitates understanding how far Turkey, as a candidate country for EU membership, is from the EU's circular economy targets and whether or not Turkey has made progress in adopting circular economy and related policies, and provides policy recommendations to policymakers to improve Turkey's performance in the circular economy.
