Several results in the word segmentation literature suggest that description length provides a useful estimate of segmentation quality in fully unsupervised settings. However, since the space of potential segmentations grows exponentially with the length of the corpus, no tractable algorithm follows directly from the Minimum Description Length (MDL) principle. Therefore, it is necessary to gene...

The Minimum Description Length (MDL) principle selects the model that has the shortest code for data plus model. We show that for a countable class of models, MDL predictions are close to the true distribution in a strong sense. The result is completely general. No independence, ergodicity, stationarity, identifiability, or other assumption on the model class need to be made. More formally, we ...

Multiple signal classification (MUSIC) algorithm has been applied to localize small scatterers for super-resolution imaging. A problem associated with this application is the estimation of the number of scatterers in presence of noise and multiple scattering between targets. In this paper, we show that the mathematical model behind the scattering from the small objects is well compatible with t...

The 6-substituted 2-(3',4'-dichlorophenoxy)-2H-pyrano[2,3-b]pyridines MDL 20,610 (6-SO2CH3), MDL 20,646 (6-Br), and MDL 20,957 (6-Cl) are potent antirhinovirus compounds with median plaque 50% inhibitory concentrations (IC1/2s) of 0.03, 0.006, and 0.006 micrograms/ml, respectively, against the 32 serotypes evaluated. The 6-halogenated analogs produced 99% reductions in progeny virion yields at ...

In the context of wavelet denoising and compression, we study minimum description length (MDL) criteria for model selection criteria as exible forms of thresholding. Mixture MDL methods based on a single Laplacian, a two-piece Laplacian, and a generalized Gaussian prior are shown to be adaptive thresholding rules. While achieving mean squared error performance comparable with other popular thre...

The metabolism of 8-methyl-8-azabicyclo- 3,2,1]octan-3-yl 3,5-dichlorobenzoate (MDL 72,222) was studied in the dog and monkey. Four urinary metabolites were detected by HPLC, HPLC/MS, and GC/MS, and were identified by comparison to authentic standards. The major metabolite in the dog, approximately 41% of the administered dose excreted between 0 and 120 hr, was the MDL 72,222-N-oxide. On the ot...

MDL 62211 is the amide derivative of the teicoplanin complex and MDL 62873 is a more focused amide derivative of the teicoplanin A2-2 peak. Each investigational compound had nearly identical activity and was 2- to 16-fold more active than teicoplanin or vancomycin. The MDL 62873 MICs for 90% of the strains tested were as follows: Staphylococcus aureus, oxacillin susceptible, 0.12 micrograms/ml;...
