This paper reports on a preliminary empirical study comparing methods for collaborative filtering (CF) using explicit consumers’ social networks. As user-generated social networks become increasingly important and visible in technology-mediated consumer interactions, we can begin to ask how the rich associated information can be used to improve inference. Theories from social psychology have lo...

One of the main disadvantage of multi-carrier CDMA (MC-CDMA) signals is the high peak power of the transmitted signals which limits their applications. To account for this issue, we provide a simple signal processing for reducing the high crest factor (CF) of MC-CDMA signals. Using this modified MC-CDMA signal, the high CF due to Walsh spreading sequences can be mitigated without explicit side ...

Based on an explicit formula of the generating series for n-point psi-class intersection numbers (cf. Bertola et al. Physica D 327:30–57, 2016), we give a novel proof conjecture Delecroix in (Duke Math J 170:2633–2718, 2021) regarding large genus uniform leading asymptotics numbers. We also investigate polynomiality phenomenon genera.

Collaborative Filtering(CF) is a widely accepted method of creating recommender systems. CF is based on the similarities among users or items. Measures of similarity including the Pearson Correlation Coefficient and the Cosine Similarity work quite well for explicit ratings, but do not capture real similarity from the ratings derived from implicit feedback. This paper identifies some problems t...

The aim of this paper is to present the s-calculus which is a very simple-calculus with explicit substitutions and to prove its connuence on closed terms and the preservation of strong normalisation of-terms. We shall prove strong normalisation of the corresponding calculus of substitution by translating it into the-calculus ACCL91], and therefore the relation between both calculi will be made ...

although explicit and implicit knowledge of language learners are essential to theoretical and pedagogical debates in second language acquisition (sla), little research has addressed the effects of instructional interventions on the two knowledge types (r. ellis, 2005).this study examined the relative effectiveness of explicit and implicit types of form-focused instruction (ffi) on the acquisit...

Recommender systems are widely used in various fields, such as e-commerce, entertainment, and education, to provide personalized recommendations users based on their preferences and/or behavior. Τhis paper presents a novel approach providing customized with the use of user-centric artificial intelligence. In greater detail, we introduce an enhanced collaborative filtering (CF) order develop hyb...

Cloud fraction (CF) significantly affects the short- and long-wave radiation. Its realistic representation in general circulation models (GCMs) still poses great challenges modeling atmosphere. Here, we present a neural network-based (NN-based) diagnostic scheme that uses grid-mean temperature, pressure, liquid ice water mixing ratios, relative humidity to simulate sub-grid CF. The scheme, trai...
