be made intrinsic to the system, rather than just parasitic on the meanings in our heads? How can the meanings of the meaningless symbol tokens, manipulated solely on the basis of their (arbitrary) shapes, be grounded in anything but other meaningless symbols? The problem is analogous to trying to learn

may produce less accurate and less understandable results, or may fail to discover anything of use at all. Feature subset selectors are algorithms that attempt to identify and remove as much irrelevant and redundant information as possible prior to learning. Feature subset selection can result

Open access to an unprecedented, comprehensive coordinated set of global coupled climate model experiments for twentieth and twenty-first century climate and other experiments is changing the way researchers and students analyze and learn about climate. The history of climate change modeling

Systems thinking and evaluating training If you mention 'training evaluation ' to anyone who has worked in the training industry for any length of time, they will almost certainly think about 'Kirkpatrick's four levels'. This taxonomy (Kirkpatrick 2006) for evaluating

efforts, under current conditions, will be ineffective and transient. He concludes with four detailed recommendations for addressing the issue of scale in improving practice in education. The Problem of Scale in Educational Reform Why do good ideas about teaching and learning have so little impact on U

. In functional encryption, ciphertexts encrypt inputs x and keys are issued for circuits C. Using the key SKC to decrypt a ciphertext CTx = Enc(x), yields the value C(x) but does not reveal anything else about x. Furthermore, no collusion of secret key holders should be able to learn anything more than the union

Articles should deal with topics applicable to the broadfield ofprogram evaluation. Articles may deal with evaluation practice or theory, but if the latter, implications for practicing evaluators should be clearly identified. Examples of contributions include, but are not limited to, reviews of new developments in evaluation and descriptions of a current evaluation effort, problem, or technique. Results of empirical evaluation studies will be published only if the methods atuUorjindings have clear utility to other evaluation practitioners. Manuscripts should include appropriate references and normally should not exceed 10 double-spaced typewritten pages in length; longer articles will occasionally be published, but only where their importance to AJE readers is judged to be quite high.

learning. Beliefs may converge to a limit point where history oers no decisive lessons for anyone, and each type's actions forever nontrivially split between two actions. To verify that our identied limit outcomes do arise, we exploit the Markov-martingale character of beliefs. Learning dynamics
