rest of the world. This is made very apparent throughout literature. In many instances, characters are seen masking sensibilities such as rebellion, anguish, and jealousy.

One case to be considered is that of Julia’s hidden rebellion in George Orwell’s 1984. Winston’s love interest, Julia, is first introduced to the readers as a good

Expectation Maximization in Collaborative Filtering Jonathan Baker 2010 Abstract Expectation maximization (EM) is a method of approximating maximum likelihood estimators (MLE) in models with missing data or latent variables. A straightforward application of EM is collaborative filtering (CF): using data from multiple agents to predict unreported values. In this paper, we show a simple method of applying EM to a large CF problem: predicting ratings in the Netflix Prize dataset. 1 Auxiliary

referred to as topics. The R package topicmodels provides basic infrastructure for fitting topic models based on data structures from the text mining package tm. The package includes interfaces to two algorithms for fitting topic models: the variational expectation-maximization algorithm provided by David M. Blei and co-authors and an algorithm using Gibbs sampling by Xuan-Hieu Phan and co-authors. Keywords: Gibbs sampling, R, text analysis, topic model, variational EM. 1.

1. The Hurwicz criterion is a compromise between the maximax and maximin criteria. The Hurwicz criterion is the weighted sum of the maximax and maximin. So, the answer is true. 2. The minimin criterion is optimistic. The minimin criterion is NOT applied to the profit payoff table. It is applied to the cost table. In this situation we want to minimize cost as much as possible. So, if we can do it this is optimistic criterion. 3. A business owner is trying to decide whether to buy, rent

These extrinsic expectations of society imprint on the mind, justifying intrinsic obsessions.

Ethical and moral justification emerges in ones actions often leading to infatuation and obsession in order to achieve society’s expectations. This is predominantly exposed within the texts “The Great Gatsby” by Fitzgerald

FROM CLASSICAL TO KENYESSIAN ECONOMICS Great Depression In the 1930s, American capitalism practically stopped working.For more than a decade, from 1929 to 1940, America's free-market economy failed to operate at a level that allowed most Americans to attain economic success. The depth economic collapse and social disarray that mired America then was unprecedented. * By 1933, the country's GNP had fallen to barely half its 1929 level12. * Industrial production fell by more than half,

suffers from deflation. How long the fall has to continue before the public and policy makers conclude that the phenomenon is reflected in expectations of future price developments is open to question. For example, in Japan, which has the distinction of experiencing the longest post World War II period of deflation, it took several years for deflationary expectations to emerge. One reason for Why deflation Can be bad for The macroeconomy, Although not necessarily linked. One reason for Why deflation

would lead to the self destruction of the system and its eventual downfall. He called on labour to revolt. ‘You have nothing to lose but your chains’ he said. His clarion call was ‘workers of the world unite’. It is an irony of history that Marx, a great philosopher, proved to be poor prophet, precisely because of his own advocacy. Had Marx not said what he did say, his prophecies would have come true. His ideas resulted in significant system reforms in Britain. Publication of Marx’s Communist Manifesto
