This paper addresses the problem of scientific research analysis. We use the topic model Latent Dirichlet Allocation [2] and a novel classifier to classify research papers based on topic and language. Moreover, we show various insightful statistics and correlations within and across three research fields: Linguistics, Computational Linguistics, and Education. In particular, we show how topics c...

Spectral topic modeling algorithms operate on matrices/tensors of word co-occurrence statistics to learn topic-specific word distributions. This approach removes the dependence on the original documents and produces substantial gains in efficiency and provable topic inference, but at a cost: the model can no longer provide information about the topic composition of individual documents. Recentl...

This paper has two main objectives: (a) Discuss the formal analogy between some important symmetry–invariance arguments used in physics, probability and statistics. Specifically, we will focus on Noether theorems in physics, maximum entropy principle in probability theory, and de Finetti type theorems in Bayesian statistics. (b) Discuss the epistemological and ontological implications of these ...

aims: hospital information system may offer a way to increased self-care management. the aim of this study was to determine the patients’ informational needs for self-care management and evaluation of different his software according to these needs.  materials & methods: this descriptive cross-sectional study was done during 2011-2012 in kashan city, iran at two phases compiling the required in...

A set of panchromatic absorbers exhibiting long excited-state lifetimes in both polar and nonpolar media has been prepared. The architectures are based on a porphyrin strongly coupled electronically to 1-4 perylene-monoimides via ethyne linkers. The constructs should find utility in molecular solar-conversion systems.

Vindija cave in Croatia has yielded the youngest securely dated Neandertal skeletal remains in Central/Eastern Europe. In addition, these remains have been found in association with archaeological material exhibiting Upper Paleolithic elements. Due to its geographic location and date, the Vindija remains are particularly crucial for the understanding of initial modern human peopling of Europe a...

Stability of Learning in Classes of The relationship to work by Mozer, [5], on induction of temporal structure, is briefly described in [13]. Recurrent and Feedforward Networks In the research reported here, the task is similar to Elman’s: predicting the next letter in a word (or the end of William H. Wilson the word) from the current letter and the representation of past letters held in the st...

A strategy to optimize the photoswitching efficiency of rigid, linear multiazobenzene constructs is presented. It consists of introducing large dihedral angles between azobenzene moieties linked via aryl-aryl connections in their para positions. Four bisazobenzenes exhibiting different dihedral angles as well as three single azobenzene reference compounds have been synthesized, and their switch...
