	Vapnik Chervonenkis theory - Wikipedia, the free encyclopedia
		Vapnik Chervonenkis theory (also known as VC theory) was developed during 1960-1990 by Vladimir Vapnik and Alexey Chervonenkis.
		The theory is a form of computational learning theory, which attempts to explains the learning process from a statistical point of view.
		VC theory is also referred to as statistical learning theory by Vapnik and his close colleagues.

	Computational learning theory - Wikipedia, the free encyclopedia
		In statistics, computational learning theory is a mathematical field related to the analysis of machine learning algorithms.
		Because the training set is finite and the future is uncertain, learning theory usually does not yield absolute guarantees of performance of the algorithms.
		For example, PAC theory inspired boosting, VC theory led to support vector machines, and Bayesian inference led to belief networks (by Judea Pearl).

		But, at the same time, the founder should not close his eyes to what the consequences of his forecast will be; accordingly, he should at least understand how venture capitalists approach the forecasts in the context of the valuation process.
		Thus, most venture capitalists contemplate a five-year time horizon, on the theory that an exit strategy is feasible at the end of five years.

	Conceptualising 'Value for the Customer': An Attributional, Structural and Dispositional Analysis by Tony Woodall (2003) (Site not responding. Last check: 2007-11-05)
		VC has attracted growing, and latterly intense, speculation, not least because it is now perceived as a key driver of satisfaction and loyalty.
		VC here is conceptualised as the benefits derived from consumption-related experience and is presented such that independence of, or at least prevalence over, any sense of associated sacrifice is implied.
		This primary VC form was earlier described as the resultant of a balancing process undertaken by a customer, based upon a personal interpretation of relevant benefits and sacrifices evident at the point of evaluation/calculus.

	XIII-P5
		Rather than treating the whole sample of VC firms as a homogeneous group, the behaviour of VC firms may be different depending on the investment stage in which they are involved (Bygrave and Timmons, 1992; Manigart et al., 2002; Wright and Robbie, 1998).
		Belgian and Swedish VC firms are very similar, while VC firms in the UK and The Netherlands are on average older (consistent with the fact that the VC industry in the UK and the Netherlands is older than in the rest of Europe) and larger in terms of investment preferences and number of investment executives.
		In addition, VC firm level control variables are included in the model: the log of the minimum investment preference, of the number of years in operation and of the number of investments in portfolio, and the degree of industry, stage and geographical specialisation.

		The applied voltage V is then zero, Vc is zero and, since there is no current flowing through R, Vr is also zero.
		Subsequently Vc begins to rise and will continue to rise exponentially until C is fully charged to +60 V in a time of 5CR seconds.
		At the instant when C is fully charged to the voltage of the supply (+60V), and Vr is consequently zero, suppose we switch back to the discharge position.

	IAS Bulletin Article: The Free Radical Theory of Aging
		Denham Harman, the "father" of the free radical theory of aging, has defined "aging" as the increased probability of death as the age of an organism increases, and diverse adverse physiologic changes accumulate.
		VC can spare and regenerate the key antioxidant GSH, which reacts enzymatically (through GPX) and non-enzymatically with a broad range of oxidants (11).
		The free radical theory of aging is not just one of the oldest and still current theories of aging - it is one of the best proven.

	Venture Capitalists As Economic Principals
		To help the VC partnership evaluate an investment in a company, the individual VC who is sponsoring the investment often prepares a detailed investment analysis or memorandum for the other partners.
		VCs explicitly consider the attractiveness of the external environment -- the market size, customer adoption, and competition -- the feasibility of the strategy and technology, the quality of the management team, and the deal terms.
		In the contracting stage, the VCs allocate rights in order to facilitate monitoring and minimize the impact of the identified risk factors, for example by allocating more control to investors when management is weak, or making founder cash flow rights and release of funds contingent on management actions.

		A second explanation--favored by entrepreneurs who raise money from VCs and who occasionally refer to them as "idiots" and "scum bags"--is that the venture business in the Valley is actually a cartel: You must be tapped by one of the established VC firms.
		The tournament theory holds that it is sometimes efficient, and in some sense right, to pay people far more than they are worth.
		The tournament theory is thus radically different from the meritocratic argument you usually hear from venture capitalists.

	Abstracts: Advances in Kernel Methods - Support Vector Learning
		We provide a novel theoretical analysis of such classifiers, based on data-dependent VC theory, proving that they can be expected to be large margin hyperplanes in a Hilbert space, and hence to have low effective VC dimension.
		The Vapnik-Chervonenkis (VC) approach to statistical learning theory (Vapnik 1979, 1995) allows one to express the complexity of a family of statistical predictors in terms of entropic quantities, the so called VC entropies.
		Classifiers with large VC complexities can have a large deviation between empirical error and generalization error, which for the case of empirical risk minimzation may lead to strong overfitting, when not enough training data are available.

	Emergent Chaos: "A Unified Theory of VC Suckage"
		That's not to say that investors are indistinguishable, only that it's even harder for a VC firm to create, maintain, and communicate a compelling advantage over the other firms.
		Most VC are in cutthroat competition with other VC for the ability to put cash into a few good companies, and a lot of 'maybes.' A good investor brings good strategic advice, and a big rolodex, and a willingness to work for you.
		But, really, the issue is that VC firms are on a ten year schedule, and that creates pressure on the startups to be on (at most) a 5-6 year schedule.

		These VCs are enabled by recent developments in computer networking, which have brought about changes in the work environment comparable to the power mechanization achieved during the industrial revolution (Kotorov, 1999).
		As VCs are temporary arrangements, the continual recasting of workgroups requires that companies identify, choose and retain potential employees with intellectual flexibility and problem-solving skills.
		Government in the United States is likely to attempt regulating those aspects of the VC within its borders that tend to reduce competition because of the anti-trust concerns unless the VC concept is sold as an international way of competing.

		VC's invest not what you need but what they want - again if a VC wants you to take more money that you need then she is a bad VC and you should find a different one.

		Abstract: In this paper we introduce and investigate a mathematically rigorous theory of learning curves that is based on ideas from statistical mechanics.
		The advantage of our theory over the well-established Vapnik-Chervonenkis theory is that our bounds can be considerably tighter in many cases, and are more reflectve of the true behavior (functional form) of learning curves.
		The disadvantages of our theory are that its application requires knowledge of the input distribution, and it is limited so far to finite cardinality function classes.

		Keywords: linear systems identification, learning theory, VC dimension 1 Introduction The problem of systems identification may be seen as an instance of the general question of "learning" an unknown function.
		Thus, one may ask if techniques from Computational Learning Theory ("CLT" in what follows; see for instance [20 ] for a general introduction, as well as the papers in the Special Issue [4 ] of Systems and Control Letters) can be used to obtain insight into this central question in control theory.
		In terms of n (the dimension of the state space) and k (the band-width) the upper bound is of the form O(n3 log 2 (nk)).

		Vapnik-Chervonenkis (VC) theory has recently emerged as a general theory for estimation of dependencies from finite samples.
		This theory emphasizes model complexity control according to Structural Risk Minimization (SRM) inductive principle, which considers a nested set of models of increasing complexity (called a structure), and then selects an optimal model complexity providing minimum error for future samples.
