Ju l 2 00 9 q - EXCHANGEABILITY VIA QUASI - INVARIANCE
For positive q, the q-exchangeability is introduced as quasi-invariance under permutations, with a special cocycle. This allows us to extend the q-analogue of de Finetti’s theorem for binary sequences [GO2] to the general real-valued sequences. In contrast to the classical case with q = 1, the order on R plays for the q-analogues a significant role. An explicit construction of ergodic q-exchang...
متن کاملExchangeability and Invariance: A Causal Theory
Despite the small numbers that appear in the table, L-N invited us to expand the sample size by whatever proportion to make it a large-sample scenario – accidental correlation due to sample variation is not an issue here. Calculate the relative frequencies, and we find a standard case of Simpson’s reversal: P(Y=1 | X=1) > P(Y=1 | X=0), but P(Y=1 | X=1, Z=0) < P(Y=1 | X=0, Z=0) and P(Y=1 | X=1, ...
متن کاملLanguage Invariance and Spectrum Exchangeability in Inductive Logic
A sufficient condition is given for a probability function in Inductive Logic (with relations of all arities) satisfying spectrum exchangeability to additionally satisfy Language Invariance. This condition is shown to also be necessary in the case of homogeneous probability functions.
متن کاملLoop Quasi-Invariance Code Motion
Loop optimization plays an important role in compiler optimization and program transformation. Many sophisticated techniques such as loop-invariance code motion, loop restructuring and loop fusion have been developed. This paper introduces a novel technique called loop quasi-invariance code motion. It is a generalization of standard loop-invariance code motion, but based on loop quasi-invarianc...
متن کاملQuasi-Circular Rotation Invariance in Image Denoising
This paper studies a new method for wavelet-based image denoising which is translation invariant (TI) and rotation invariant (RI). These invariances are crucial in image denoising and, more generally, may play important roles in image modeling. In contrast to other approximately RI methods, like the steerable pyramid, our new method employs standard separable wavelet bases in conjunction with a...
