Logarithmic Time One-Against-Some

چکیده

LTCB is the Large Text Compression Benchmark, consisting of the first billion bytes of a particular Wikipedia dump (Mahoney, 2009). Originally developed to study text compression, it is now commonly used as a language modeling benchmark where the task is to predict the next word in the sequence. We limit the vocabulary to 80000 words plus a single out-of-vocabulary indicator; utilize a model linear in the 6 previous unigrams, the previous bigram, and the previous trigram; and utilize a 90-10 train-test split on entire Wikipedia articles.

Thermal anomalies detection before earthquake using three filters (Fourier, Wavelet and Logarithmic Differential Filter), A Case Study of two Earthquakes in Iran

Earthquake is one of the most destructive natural phenomena which has human and financial losses. The existence of an efficient prediction system and early warning system will be useful for reducing effects of destroying earthquake. In this research, the soil temperature time-series data, obtained from three meteorological station, using three filters (Fourier, Wavelet and Logarithmic Different...

Logarithmic Time One-Against-Some

We create a new online reduction of multiclass classification to binary classification for which training and prediction time scale logarithmically with the number of classes. We show that several simple techniques give rise to an algorithm that can compete with one-against-all in both space and predictive power while offering exponential improvements in speed when the number of classes is large.

Estimating Height and Diameter Growth of Some Street Trees in Urban Green Spaces

Estimating urban trees growth, especially tree height is very important in urban landscape management. The aim of the study was to predict of tree height base on tree diameter. To achieve this goal, 921 trees from five species were measured in five areas of Mashhad city in 2014. The evaluated trees were ash tree (Fraxinus species), plane tree (Platanus hybrida), white mulberry (Morus alba), ail...

A $O(\log m)$, deterministic, polynomial-time computable approximation of Lewis Carroll's scoring rule

We provide deterministic, polynomial-time computable voting rules that approximate Dodgson’s and (the “minimization version” of) Young’s scoring rules to within a logarithmic factor. Our approximation of Dodgson’s rule is tight up to a constant factor, as Dodgson’s rule is NP-hard to approximate to within some logarithmic factor. The “maximization version” of Young’s rule is known to be NP-hard...

An Improvement in Temporal Resolution of Seismic Data Using Logarithmic Time-frequency Transform Method

The improvement in the temporal resolution of seismic data is a critical issue in hydrocarbon exploration. It is important for obtaining more detailed structural and stratigraphic information. Many methods have been introduced to improve the vertical resolution of reflection seismic data. Each method has advantages and disadvantages which are due to the assumptions and theories governing their ...

Experimental and Mathematical Investigation of Time-Dependence of Contaminant Dispersivity in Soil

Laboratory and field experiments have shown that dispersivity is one of the key parameters in contaminant transport in porous media and varies with elapsed time. This time-dependence can be shown using a time-variable dispersivity function. The advantage of this function as opposed to constant dispersivity is that it has at least two coefficients that increase the accuracy of the dispersivity p...
