自由和责任

自由是一个伟大的字眼。追求自由。是人的一种权利，也是人的一种本能。这一权利不是天生就有的，是人类通过自身的努力和斗争实现的。人类为自身的自由奋斗了几千年，从某种意义上说，一部人类发展史就是人类为了争取平等和自由而奋斗的历史。现在，在世界上的大部分地区，确保人民平等和自由的权利已成为一个政府存在的前提条件，也是一个国家进步和文明的标志。

汉库：勇走机器人产业化之路

作为高新技术产品，在很多人的观念里，机器人就是强国的象征。不过，在过去很多年时间里，这种高科技产品离普通老百姓的生活是遥远的，给人的感觉是“只可远观而不可亵玩焉”!机器人何时能“飞入寻常百姓家”？这一直是不少人尤其是青少年的深切期盼。值得欣慰的是，作为世界机器人的“祖先”，中国在机器人领域的研究一直没有停滞，改革开放后的发展速度尤其迅猛，

纳兰，生如夏花之绚烂

纳兰词广为流传，从他的词中读出的是一种天地问的至柔深情，像埋藏在灰烬里永不熄灭的火种，一再点燃你。其词作内不仅反映了个人的悲欢离合，而且具有“词史”意义，反映了当时社会状态下人的生存困窘和情感波澜。近代著名学者王国维给其极高赞扬：

Graph-Based Entropy for Detecting Explanatory Signs of Changes in Market

Graph-based entropy, an index of the diversity of events in their distribution to parts of a co-occurrence graph, is proposed for detecting signs of structural changes in the data that are informative in explaining latent dynamics of consumers’ behavior. For obtaining graph-based entropy, connected sub-graphs are first obtained from the graph of co-occurrences of items in the data. Then, the distribution of items occurring in events in the data to these sub-graphs is reflected on the value of graph-based entropy. For the data on the position of sale, a change in this value is regarded as a sign of the appearance, the separation, the disappearance, or the uniting of consumers’ interests. These phenomena are regarded as the signs of dynamic changes in consumers’ behavior that may be the effects of external events and information. Experiments show that graph-based entropy outperforms baseline methods that can be used for change detection, in explaining substantial changes and their signs in consumers’ preference of items in supermarket stores.     

A New Type of Computer Premium and Its Correlation to Individual Wages

This paper examines statistical correlations between workers?? income levels or wages, and Information and Communication Technology (ICT). The analyzed data set is micro data collected through the Web in 2008 and 2010 by the Research Institute for Socionetwork Strategies. This micro data estimates the rank correlation of income classes with respect to three types of ICT labor service. Next, multiple linear regression functions are estimated for the wage levels with respect to age, sex, years of continuous employment, and three types of ICT labor service over all industries and in the manufacturing industry or service industry. Finally, a multiple regression analysis is conducted for individual utility levels with respect to income, leisure, and three types of ICT labor service. The results show that, first, the coefficients of rank correlation for all pooled data are positive and statistically significant. Second, individual ICT labor services have positive effects on workers?? wage levels, and the partial regression coefficients are statistically significant. Third, the partial regression coefficient of personal computer operation time decreased but the partial regression coefficient of mobile computer operation time related to work increased drastically from 2008 to 2010. Fourth, the use of the personal and mobile computer shifts the utility function upward with respect to income and leisure.     

Prediction Model for Bollywood Movie Success: A Comparative Analysis of Performance of Supervised Machine Learning Algorithms

The main purpose of this paper is to do a comparative analysis of prediction models using various machine learning techniques. The models will be used to predict whether a movie will be a hit or flop before it is actually released. The techniques used for comparisons are decision tree, random forest (RF), support vector machine, logistics regression, adaptive tree boosting, and artificial neural network algorithms. The major predictors used in the models are the ratings of the lead actor, IMDb ranking of a movie, music rank of the movie, and total number of screens planned for the release of a movie. The results of most models indicated a reasonable accuracy, ranging from 80 to 90%. However, models based on two techniques, RF and logistic regression, achieved an accuracy of 92%. From the results, the most important predictors of a movie’s success are music rating, followed by its IMDb rating and total screens used for release.
