Evolvability need not imply learnability
We show that Boolean functions expressible as monotone disjunctive normal forms are PAC-evolvable under a uniform distribution on the Boolean cube if the hypothesis size is allowed to remain fixed. We further show that this result is insufficient to prove the PAC-learnability of monotone Boolean functions, thereby demonstrating a counter-example to a recent claim to the contrary. We further dis...
متن کاملVertical or asymmetric nystagmus need not imply neurological disease.
AIM To indicate that congenital idiopathic nystagmus (CIN) and sensory defect nystagmus (SDN) can be vertical or asymmetric in some children. METHODS Of 276 children presenting with nystagmus for electrophysiological testing, 14 were identified as having CIN or SDN, yet had a nystagmus which was either vertical (n=11) or horizontal asymmetric (n=3). Flash electroretinograms and flash and patt...
متن کاملSuperintelligence Does Not Imply Benevolence
Asmachines become capable ofmore autonomous and intelligent behavior, will they also display more morally desirable behavior? Earth’s history tends to suggest that increasing intelligence, knowledge, and rationality will result in more cooperative and benevolent behavior. Animals with sophisticated nervous systems track and punish exploitative behavior, while rewarding cooperation. Humans form ...
متن کاملCount(q) Does Not Imply Count(p)
I solve a conjecture originally studied by M. Ajtai. It states that for different primes q, p the matching principles Count(q) and Count(p) are logically independent. I prove that this indeed is the case. Actually I show that Count(q) implies Count(p) exactly when each prime factor in p also is a factor in q. 1 The logic of elementary counting “She loves me, she loves me not, she loves me,. . ....
متن کاملDiversity does not Necessarily Imply Adaptability
Dynamic optimiser design currently assumes that diversity is a desirable property towards achieving adaptability, as a population-based optimiser contains an implicit memory. This paper examines the applicability of this assumption. Population-based algorithms of different size are tested against optimisers using a single solution. Results presented here suggest that this view is somewhat simpl...
