We describe CST, an online algorithm for constructing skill trees from demonstration trajectories. CST segments a demonstration trajectory into a chain of component skills, where each skill has a goal and is assigned a suitable abstraction from an abstraction library. These properties permit skills to be improved efficiently using a policy learning algorithm. Chains from multiple demonstration ...

This paper presents the results of two experiments on singing skill evaluation, where human subjects judge the subjective quality of previously unheard melodies. The aim of this study is to explore the criteria that human subjects use in judging singing skill and the stability of their judgments, as a basis for developing an automatic singing skill evaluation scheme. The experiments use the ran...

this paper investigates the effect of foreign trade and human capital on economic growth using pooling data for the oic member countries over the period 1980-2003. for this purpose, the soderbom-teal (2003) growth model is re-specified with the variables such as growth of manufacturing exports, manufacturing imports, human capital, labor force and physical capital. the empirical results indicat...

Extant research pays little attention to migrant workers’ skill accumulation/upgrading from the perspective of the labor supply. This paper takes China as an example to explore the factors influencing skill accumulation of rural-urban migrant workers (RUMWs), with a purpose to discover how to sustain or reshape regional competitive advantage through improving RUMWs’ skill accumulation. Structur...

Controlling a complex dynamic system, such as a plane or a crane, usually requires a skilled operator . Such a control skill is typically hard to reconstruct through introspection . Therefore an attractive approach to the reconstruction of control skill involves machine learning from operators' control traces, also known as behavioural cloning . In the most common approach to behavioural clonin...

Education-job mismatches are reported to have serious effects on wages and other labour market outcomes. Such results are often cited in support of assignment theory, but can also be explained by institutional and human capital models. To test the assignment explanation, we examine the relation between educational mismatches and skill mismatches. In line with earlier research, educational misma...

This paper quantitatively examines the e¤ects of two exogenous driving forces, investment-speci…c technological change (ISTC) and the demographic change known as “the baby boom and the baby bust,”on the evolution of the skill premium in the postwar U.S. economy. I develop an overlapping generations general equilibrium model with endogenous discrete schooling choice. The production technology fe...

background and purpose: clinical competence has four essential components: knowledge , physical exam , problem solving and communication skill .the communication skill isn’t an optional extra in medical training but it is a core clinical skill. this study is performed in order to determine whether communication skill training for internal medicine and infectious disease residents improves their...

We describe recent work on CST, an online algorithm for constructing skill trees from demonstration trajectories. CST segments a demonstration trajectory into a chain of component skills, where each skill has a goal and is assigned a suitable abstraction from an abstraction library. These properties permit skills to be improved efficiently using a policy learning algorithm. Chains from multiple...

We introduce neighborhood effects in the costs of human capital acquisition into a model of statistical discrimination in labor markets. This creates a link between the level of segregation and the likelihood and extent of statistical discrimination. As long as negative stereotypes persist in the face of increasing integration, skill levels rise in the disadvantaged group and fall in the advant...
