In the feature subset selection problem, a learning algorithm is faced with the problem of selecting a relevant subset of features upon which to focus its attention, while ignoring the rest. To achieve the best possible performance with a particular learning algorithm on a particular training set

... describe music. They are commonly used to structure the increasing amounts of music available in digital form on the Web and are important for music information retrieval. Genre categorization for audio has traditionally been performed manually. A particular musical genre is characterized

Although the relationship metaphor dominates contemporary marketing thought and practice, surprisingly little empirical work has been conducted on relational phenomena in the consumer products domain, particularly at the level of the brand. In this article, the author: (1) argues for the validity

is essential. (iv) Relearning after damage is much faster than learning during the original training. (v) Distributed or spaced practice is more effective for long-term retention than massed practice. Network models can be constructed that have the same performance and learning characteristics on a particular

of the Earth's orbit 1,3 . But understanding how the climate system responds to this initial orbital forcing is still an important issue in palaeoclimatology, in particular for the generally strong ϳ100,000-year (100-kyr) cycle. Ice cores give access to palaeoclimate series that includes local

in normal human cognition (see Fiske& Taylor, 1984; In this article, we review research suggesting that certain illusions may be adaptive for mental health and well-being. In particular, we examine evidence that a set of interrelated positive illusions-namely, unrealistically positive self

Sustainable development is popularly described as “a development that meets the needs of the present without compromising the ability of the future generations to meet their own needs”

We are grateful to Yongsung Chang and three referees, particularly the final referee, for useful comments. Saasha Celestial-One provided excellent research assistance. Does Schooling Cause Growth? Barro (1991) and others find that growth and schooling are highly correlated across countries. A model

appear. Both facts could be observed in single unit recordings in delayed match to sample experiments. 5. Beyond this critical learning strength the local module has two types of collective activity. It either participates in the global spontaneous activity, or it maintains a stimulus selective elevated

, it proposes a novel framework for analyzing and comparing consumer opinions of competing products. A prototype system called Opinion Observer is also implemented. The system is such that with a single glance of its visualization, the user is able to clearly see the strengths and weaknesses of each product
