The vast number of biomedical literature is an important source of biomedical interaction information discovery. However, it is complicated to obtain interaction information from them because most of them are not easily readable by machine. In this paper, we present a method for extracting biomedical interaction information assuming that the biomedical Named Entities (NEs) are already identifie...

The differences and relations of various negations have attracted interest in logical investigation, and most of the studies have utilized a model-theoretic approach (cf. Dunn 1999, Shramko 2005, Ripley 2009). This study will propose a general framework to treat various negations from the perspective of proof-theoretic semantics (PTS) based on natural deduction. It is well known that when we de...

The simulation of various natural phenomena is one of the important research fields in computer graphics. In particular, aspects such as sky, clouds, water, fire, trees, smoke, terrains, desert scenes, snow and fog are indispensable for creating realistic images of natural scenes, flight simulators and so on. Therefore, a lot of researchers have been trying to develop methods for simulating and...

The natural gradient method has an ideal dynamic behavior which resolves the slow learning speed of the standard gradient descent method caused by plateaus. However, it is required to calculate the Fisher information matrix and its inverse, which makes the implementation of the natural gradient almost impossible. To solve this problem, a preliminary study has been proposed concerning an adaptiv...
