Mobile robots often rely upon systems that render sensor data and perceptual features into costs that can be used in a planner. The behavior that a designer wishes the planner to execute is often clear, while specifying costs that engender this behavior is a much more difficult task. This is particularly apparent when attempting to simultaneously tune many parameters that define the mapping fro...

This paper investigates the effects of a change in the margin rules of the U.S. stock market. These rules determine how much investors can borrow to leverage their investments. Since the 1929 stock market crash, margin loans have been tightly regulated by the Securities and Exchange Act Regulation T. Between 2005 and 2008, the Securities and Exchange Commission modified these margin rules becau...

In this paper, we study the non-monotone DR-submodular function maximization over integer lattice. Functions lattice have been defined submodular property that is similar to submodularity of set functions. a further extended concept for functions lattice, which captures diminishing return property. Such find many applications in machine learning, social networks, wireless etc. The techniques ca...

The paper deals with the design of the robust PID controller for real uncertain Coupled-Tank process in the frequency domain. Only the first independent tank is considered (single-input single-output system). Robust controller is designed in two ways. The first approach is performed with the Edge Theorem and the Neimark’s D -partition method for the affine model and the second one is performed ...

We have recently proposed an extension of ADABOOST to regression that uses the median of the base regressors as the final regressor. In this paper we extend theoretical results obtained for ADABOOST to median boosting and to its localized variant. First, we extend recent results on efficient margin maximizing to show that the algorithm can converge to the maximum achievable margin within a pres...

Objectives The study considers how online home-based businesses offer opportunities for ethnic entrepreneurs to ‘break out’ of the traditional highly competitive and low margin sectors they are often associated with. Prior Work Previous studies have found a positive association between ethnic minorities high levels of entrepreneurship (Levie, 2007) and between home computer use and entrepreneur...

We 2 present a method for face class modeling in the eigenfaces space using a large-margin classifier like SVM. Another issue addressed is how to select the number of eigenfaces to achieve a good classification rate. As the experimental evidence show, generally one needs less eigenfaces than usually considered. We will present different strategies and discuss their effectiveness in the case of ...

In this paper, we approached the concept of real estate bubble, analyzing risk its bursting could generate for Chilean financial market. Specifically, analyzed relationship between housing prices, economic activity index, and mortgage interest rates denominated in inflation-linked units from 1994 to 2020. The analysis was based on a second order Markov switching model with predetermined variabl...

This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...

This paper presents a new method for computing the stability margin of two-dimensional (2-D) continuous systems. The method is based on the computation of the Hermite matrix in 2-D continuous systems, one of its partial derivatives and their resultant. The theoretical result is illustrated by examples.
