Based on the duality that the asymptotic properties of statistical inference in the limit of an in nite number of observations hold for geometric tting in the limit of in nitesimal perturbations, we de ne the geometric MDL as the dual to Rissanen's MDL and give an information-theoretic interpretation. Doing numerical simulations and real image virtual studio experiments, we observe that the geo...

We propose a simple algorithm for improving the MDL (minimum description length) estimator of the number of sources of signals impinging on multiple sensors. The algorithm is based on the norms of vectors whose elements are the normalized and nonlinearly scaled eigenvalues of the received signal covariance matrix and the corresponding normalized indexes. Such norms are used to discriminate the ...

In this paper, we propose two modifications to the original Minimum Description Length (MDL) score for learning of Bayesian networks. The first modification is that the description of network structure is proved to be unnecessary and can be omitted in the total MDL score. The second modification consists in reducing the description length of conditional probability table (CPT). In particular, i...

Radiolabelled piperidine derivatives such as [(11)C]MDL 100907 and [(18)F]altanserin have played an important role in diagnosing malfunction in the serotonergic neurotransmission. A variety of novel piperidine MDL 100907 derivatives, possible to label with (18)F-fluorine, were synthesized to improve molecular imaging properties of [(11)C]MDL 100907. Their in vitro affinities to a broad spectrum...

The ethnic drug Melastoma dodecandrum Lour. (MDL) is widely distributed throughout South China, and is the major component of Gong Yan Ping Tablets/Capsules and Zi Di Ning Xue San. Although the pharmacological effects of MDL have been well documented, its chemical profile has not been fully determined. In this study, we have developed a rapid and sensitive UPLC-ESI-Q-Exactive Focus-MS/MS method...

Modal dependence logic (MDL) was introduced recently by Väänänen. It enhances the basic modal language by an operator =(·). For propositional variables p1, . . . , pn the atomic formula =(p1, . . . , pn−1, pn) intuitively states that the value of pn is determined solely by those of p1, . . . , pn−1. We show that model checking for MDL formulae over Kripke structures is NPcomplete and further co...

BACKGROUND AND PURPOSE The competitive N-methyl-D-aspartate antagonist MDL-100,453 was used to determine whether a neuroprotective effect is demonstrable when the drug is administered beginning 30 minutes after the initiation of focal ischemia and whether the effect is related to blood levels of the drug. METHODS Forty-eight Sprague-Dawley rats were randomly assigned to one of four intravenou...

Multidistrict litigation procedures have grown in significance as an important tool for resolving large-scale litigation. Indeed, in recent years, various reports have noted that from one third to one half of all cases in the federal courts are part of MDL proceedings.1 From the defendants’ perspective, consolidation in a federal MDL proceeding may make nationwide litigation more manageable. Fr...

The calpain inhibitor MDL-28710 blocks the early local pro-inflammatory cytokine gene expression in mice after chronic constriction nerve injury (CCI). One-hundred-thirteen wild type mice of C57Bl/6J background received CCI of the right sciatic nerve. Mechanical paw withdrawal thresholds and thermal withdrawal latencies were investigated at baseline and at 1, 3, and 7 days after CCI. Three appl...

Minimum Description Length (MDL) is an important principle for induction and prediction, with strong relations to optimal Bayesian learning. This paper deals with learning non-i.i.d. processes by means of two-part MDL, where the underlying model class is countable. We consider the online learning framework, i.e. observations come in one by one, and the predictor is allowed to update his state o...
