Restoration of Vitality Through Conjugation

Shaping human mortality patterns through intrinsic and extrinsic vitality processes

BACKGROUND While historical declines in human mortality are clearly shaped by lifestyle and environmental improvements, modeling patterns is difficult because intrinsic and extrinsic processes shape mortality through complex stochastic interactions. OBJECTIVE To develop a stochastic model describing intrinsic and extrinsic mortality rates and quantify historical mortality trends in terms of par...

Object Restoration through Dynamic Polygons

Restoration of retinal images obtained through cataracts.

An optical model for imaging the retina through cataracts has been developed. The images are treated as sample functions of stochastic processes. On the basis of the model a homomorphic Weiner filter can be designed that will optimally restore the cataractous image (in the mean-square-error sense). The design of the filter requires a priori knowledge of the statistics of either the cataract tra...

Lexical Disambiguation of Igbo through Diacritic Restoration

Properly written texts in Igbo, a low resource African language, are rich in both orthographic and tonal diacritics. Diacritics are essential in capturing the distinctions in pronunciation and meaning of words, as well as in lexical disambiguation. Unfortunately, most electronic texts in diacritic languages are written without diacritics. This makes diacritic restoration a necessary step in cor...
