This lecture is about different techniques used for video streaming to improve performance and Quality of Experience (QoE). Specifically, we learned about ”neural adaptive video streaming with Pensieve” [1]. Pensieve adaptively selects bitrates (ABR) for future video chunks based on observations collected by client video players. It automatically learns ABR algorithms that adapt to a wide range...

Due to the fact that assets are recorded at their historical value and they may include unrealized gains (losses), managers may manipulate earnings through the sale of these assets and provide financial information which is not accurate and reliable. The aim of this study is to investigate the relationship between income from asset sales, earnings change and leverage of companies listed on Tehr...

Large heterogeneity has prevented current capital structure research from explaining variations in firms’ capital structures to a satisfactory degree. We find that firms generally fall into two categories based on their capital structure policies. One category consists of larger firms that tend to pay dividends, and includes almost all zero-leverage firms in the sample. These firms tend to resp...

The sampling strategies in many randomized matrix algorithms are, either explicitly or implicitly, controlled by statistical quantities called leverage scores. We present four bounds for the sensitivity of leverage scores as well as an upper bound for the principal angles between two matrices. These bounds are expressed by considering two real m×n matrices of full column rank, A and B. Our boun...
