We address the problem of transferring skills learned from interactive demonstrations. Learning from Demonstration is an effective method for quickly learning to complete a task; however, task demonstrations are often provided within a particular environment, and thus cannot be immediately repeated in unfamiliar environments that differ in object configurations and features. We describe our ong...

This paper proposes an effective method for automatic melody extraction in polyphonic music, especially vocal melody songs. The method is based on subharmonic summation spectrum and harmonic structure tracking strategy. Performance of the method is evaluated using the LabROSA database 1 . The pitch extraction accuracy of our method is 82.2% on the whole database, while 79.4% on the vocal part.

An introductory note of the talk on cosmology. Some of the text are copied from the talk by G. Lazarides, http://arxiv.org/pdf/hep-ph/9904502v2.pdf. As of the date: May 29, 2012.

In this paper, we investigate how topic dynamics during the course of an interaction correlate with the power differences between its participants. We perform this study on the US presidential debates and show that a candidate’s power, modeled after their poll scores, affects how often he/she attempts to shift topics and whether he/she succeeds. We ensure the validity of topic shifts by confirm...

We study the connection between the number of ascending and descending cuts of a linear order, its classical size, and its effective complexity (how much [how little] information can be encoded into it).

Online education has become popular as an effective method of imparting knowledge to a wide audience efficiently and at low cost. Unlike traditional ”offline” courses, online courses open up the possibility of fine-grained tracking and monitoring of students’ activities, progress and performance. In turn, this creates the possibility of of analyzing the factors involved in student success, rete...

The one-loop effective potential in 2D dilaton gravity in conformal gauge on the topologically non-trivial plane IR×S and on the hyperbolic plane H/Γ is calculated. For arbitrary choice of the tree scalar potential it is shown, that the one-loop effective potential explicitly depends on the reference metric (through the dependence on the radius of the torus or the radius of H/Γ). This phenomeno...

Under the APA (5 U.S.C. 551–553) our normal practice is to publish policies with a 30-day delay in effective date. In this case, however, we use the ‘‘good cause’’ exemption under 5 U.S.C. 553(d)(3) to make this rule effective upon publication. This rule relieves a restriction, and it is not in the public interest to delay its effective date. We believe that another nontoxic shot option likely ...
