15.097 Prediction: Machine Learning and Statistics (MIT)
Prediction is at the heart of almost every scientific discipline, and the study of generalization (that is, prediction) from data is the central topic of machine learning and statistics, and more generally, data mining.

2 The road to Doha

The WTO was created by the eighth in a series of multilateral trade negotiations that have taken place since the signing in 1947 of the General Agreement on Tariffs and Trade (GATT). Multilateral trade negotiations take place between many countries simultaneously. (Bilateral negotiations are negotiations between pairs of countries.) The GATT was designed to prevent a repetition of the experience of the 1930s, when individual countries had tried to claw their way out of the widespread u

"Ecology, Human Rights, and Large Dam Projects in South Asia"
Kathleen Morrison is Professor, Department of Anthropology; Director, Center for International Studies, The University of Chicago. There is little doubt that climate change, deforestation, erosion, and the unequal distribution of natural resources around the globe are of pressing importance everywhere, but these problems are perhaps most acute in Asia, home to 64 percent of the world’s population. Much of this population (1 and 1.3 billion, respectively) is concentrated in India and China, tw

The ACSM recommends exercise that employs large muscle groups, is rhythmic or dynamic, can be maintained continuously and is aerobic in nature (ACSM, 2006; Pollock et al., 1998). This type of exercise results in larger increases in VO2max. Activities that would fit into this category include walking, running, swimming and cycling.

2.3.2 Love

Please now read ‘Dogs and Wolves’.

This poem is amazing in its forceful, simple-seeming expression of an extraordinarily complex combination of thought and emotion. The ‘dogs and wolves’ are the speaker's ‘unwritten poems’. Why ‘unwritten’? One infers that other matters take priority over love poems. But – ‘unwritten’ – their la

Unde et Quo
To begin with, I would like to say a few words about the problem of alienation of modern technologies which we also inevitably faced while starting teaching CAD at our department. Quite often nowadays a technology becomes a fetish as a result of lack of clear goals in human mind. There are multiple technologies without sense of purpose which turned into pure experiments. There is always the danger of losing purposeness and drifting toward alienation. The cause of the danger lies in forgetting ab

But what are the implications of these developments and trends? Clearly the emergence of a strong east-Asian bond market could threaten both the US dollar and the Euro markets, but this development is still in its infancy, and there are significant political and economic differences of interest amongst the possible east-Asian participants in such a market. So for the time being it will be the Euro and the US dollar that hold centre stage. But in as much as the Euro becomes a stronger currency

Algorithm For The Automatic Design Of A Shading Device
Given that there is a need to shade a window from the summer sun and also a need to expose it to the winter sun, this article describes an algorithm to design automatically a geometric construct that satisfies both requirements. The construct obtained represents the minimum solution to the simultaneous requirements. The window may be described by an arbitrary convex polygon and it may be oriented in any direction and it may be placed at any chosen latitude. The algorithm consists of two sequenti
