Our goal is to estimate a probability density based on discrete point data via segmentation techniques. Since point data may represent certain activities, such as crime, our method can be successfully used for detecting regions of high activity. In this work we design a binary segmentation version of the well-known Maximum Penalized Likelihood Estimation (MPLE) model, as well as a minimization ...

Oftenti mes we need to investigate m ore than one source of data to provide a solution to the proble m at hand. This data integration proble m has been investigated and largely solved for simple situations in traditional relational database m a n age me nt syste ms (RDBMSes). They typically provide a m e a ns for the user to join datasets together based on a co m mo n si mple attribute. Not all...

We propose a new sparse estimation method for Cox (1972) proportional hazards models by optimizing an approximated information criterion. The main idea involves approximation of the ℓ0 norm with a continuous or smooth unit dent function. The proposed method bridges the best subset selection and regularization by borrowing strength from both. It mimics the best subset selection using a penalized...

A p-adic variation of the Ran(dom) Sa(mple) C(onsensus) method for solving the relative pose problem in stereo vision is developped. From two 2-adically encoded images a random sample of five pairs of corresponding points is taken, and the equations for the essential matrix are solved by lifting solutions modulo 2 to the 2-adic integers. A recently devised p-adic hierarchical classification alg...

We propose a two-stage estimation method for random coefficient ordinary differential equation (ODE) models. A maximum pseudo-likelihood estimator (MPLE) is derived based on a mixed-effects modeling approach and its asymptotic properties for population parameters are established. The proposed method does not require repeatedly solving ODEs, and is computationally efficient although it does pay ...

An improved formula is derived for accurately computing the near-zone magnetic field of a s mall c irc ular transmitting loop an tenna. Such a field can serve as a reference standard for calibrating fi eld-strength meters e mploying small receiving loop anten nas in the frequency range 30 Hz to 30 MHz.

Mple dog’s express their feelings by oscillating his tail. Similarly cows express their feelings with his feet, neck and tail. Every feeling has its distinct body movements. So by placing this model on their communicating body part we transform the animal feelings into words and phrases. This model also helps the deaf and dumb community to communicate with others in oral langage. Prototype of s...
