We propose a linearly penalized support vector machines (LP-SVM) model for feature selection. Its application to a problem of customer retention and a comparison with other feature selection techniques underlines its effectiveness.

The paper analyzes the decision made by firms to issue one-time coupons as a means of attracting new deal-prone customers. Given the structure of the market and the share of loyal customers, we derive boundaries for the value of the coupon, as well as the optimal face value of the coupon. The main variables which determine the coupon value are: the size of deal-prone and loyal market segments, ...

Cross-selling is becoming an increasingly prevalent practice in call centers, due, in part, to its unique capability to allow firms to dynamically segment their callers and customize their product offerings accordingly. This paper considers a call center with cross-selling capability that serves a pool of customers that are differentiated in terms of their revenue potential and delay sensitivit...

This paper describes F0 segment selection, a novel syllablebased F0 conversion method, which provides a concatenative framework to search for F0 segments in a modest corpus of emotional speech (∼15 minutes of data). The method is compared with our earlier work on F0 generation using contextsensitive syllable HMMs. Both methods are complemented with a duration conversion module as well as GMM-ba...

How do we select combinations of limb segments to carry out physical tasks? Three possible determinants of limb-segment selection are hypothesized here: (1) optimal amplitudes and frequencies of motion for the effectors; (2) preferred movement axes for the effectors; and (3) a tendency to continue using already-recruited limb-segments. We tested these factors in a graphic production task. Seven...

This research was initiated in an attempt to understand customer intentions towards purchasing from an Internet bookstore. Ajzen’s theory of planned behavior was used to predict the intentions and behavior of different customer groupings based on their lifestyle and personality. Factor and cluster analyses were used to segment the sample into three clusters. Data were then collected in seven co...

Previous research provides evidence that the ‘entertaining shopping experience’ is influenced by dependent variables of retailer factors and customer factors. Yet few studies have investigated the moderating effect of transportation mode factors upon retailer factors and customer factors. This paper addresses these issues in context of the looming mobility concerns that accompany Australia’s fa...

In his Physics of Life review, Vologodskii [1] advocates for a “merging” of the hooked-juxtaposition [2] and bendangle (bent G segment) [3,4] models of disentangling by type II topoisomerases (topoIIs). His review is significant because it signals an emerging consensus, at least among theoreticians, that topoIIs perform T-segment selection [5]. As a researcher of DNA topology who has made impor...
