Zhu Xi’s Method of Phonetic Annotation in Ancient Chinese Books
Zhu Xi is not only a master of Confucianism, but also has made great achievements in exegesis. By studying Zhu Xi’s exegetical thoughts and methods in the practice of exegesis, we can correctly evaluate Zhu Xi’s historical position in the history of Chinese exegesis.This article discusses Zhu Xi’s methods of phonetic annotation, including Zhi Yin (direct sound), Bi Kuang (comparison), Fan Qie (recomposition), Bie Si Sheng and Biao Ru Zi (four tones) and Xie Yin (rhyme) in exegesis of ancient books. These annotations retain the actual phonetics of the Song Dynasty and are very important for studies of Chinese phonetics history
Bounded Coordinate-Descent for Biological Sequence Classification in High Dimensional Predictor Space
We present a framework for discriminative sequence classification where the
learner works directly in the high dimensional predictor space of all
subsequences in the training set. This is possible by employing a new
coordinate-descent algorithm coupled with bounding the magnitude of the
gradient for selecting discriminative subsequences fast. We characterize the
loss functions for which our generic learning algorithm can be applied and
present concrete implementations for logistic regression (binomial
log-likelihood loss) and support vector machines (squared hinge loss).
Application of our algorithm to protein remote homology detection and remote
fold recognition results in performance comparable to that of state-of-the-art
methods (e.g., kernel support vector machines). Unlike state-of-the-art
classifiers, the resulting classification models are simply lists of weighted
discriminative subsequences and can thus be interpreted and related to the
biological problem
Quantum-State Engineering of Multiple Trapped Ions for Center-of-Mass Mode
We propose a scheme to generate a superposition with arbitrary coefficients
on a line in phase space for the center-of-mass vibrational mode of N ions by
means of isolating all other spectator vibrational modes from the
center-of-mass mode. It can be viewed as the generation of previous methods for
preparing motional states of one ion. For large number of ions, we need only
one cyclic operatin to generate such a superposition of many coherent states.Comment: 14 pages, revte
Beyond Gr\"obner Bases: Basis Selection for Minimal Solvers
Many computer vision applications require robust estimation of the underlying
geometry, in terms of camera motion and 3D structure of the scene. These robust
methods often rely on running minimal solvers in a RANSAC framework. In this
paper we show how we can make polynomial solvers based on the action matrix
method faster, by careful selection of the monomial bases. These monomial bases
have traditionally been based on a Gr\"obner basis for the polynomial ideal.
Here we describe how we can enumerate all such bases in an efficient way. We
also show that going beyond Gr\"obner bases leads to more efficient solvers in
many cases. We present a novel basis sampling scheme that we evaluate on a
number of problems
