US economy adds 119,000 jobs in September as unemployment rate rises
Does'America First' make the US weaker? Who is Marjorie Taylor Greene? United States job growth accelerated in September despite a cooling job market as the unemployment rate rose. Nonfarm payrolls grew by 119,000 jobs after a downwardly revised 4,000 drop in August, according to the Bureau of Labor Statistics (BLS) report released on Thursday. The healthcare sector had the most gains, totalling 43,000 jobs in September.
Faster Online Learning of Optimal Threshold for Consistent F-measure Optimization
Xiaoxuan Zhang, Mingrui Liu, Xun Zhou, Tianbao Yang
In this paper, we consider online F-measure optimization (OFO). Unlike traditional performance metrics (e.g., classification error rate), F-measure is non-decomposable over training examples and is a non-convex function of model parameters, making it much more difficult to be optimized in an online fashion. Most existing results of OFO usually suffer from high memory/computational costs and/or lack statistical consistency guarantee for optimizing F-measure at the population level.
