Formal Context

A formal context is a triple of sets (O,A,I)
where

O is a set of objects
A is a set of attributes
I is a binary relation between A and O (O X A Matrix)

The notation oIa,
where
o is a member of O
a is a member of A

(o,a) is a member of I

More simply, the formal context can be visualized as a vector space model
where each row represents an object from O and each column represents an attribute from A. Each matrix element presents the occurence/existence of attribute a in object o. Various variant of such a model exists with the different being the matrix element function. For example, the matrix element value might represent the degree of significant of the attribute a in object o, instead of simply representing the existence.

Ahem Ahem. Listen to this...

漫長的路

仰望著天空 看到了滿天的秘密
快告訴我 我是喝醉了

愛吧 笑吧 相信吧 等吧
我在等 等著熟悉的今天

因為今天不在是屬於我一個人
進步是當你決定放手一搏的時候 放手一搏吧

我 只想換回一個真正的我

NERD MUST HAVE: Ergonomic Handkerchief

This series of handkerchief comes with a nose pouch, which supposed your nose will fits in when you sneezed. Theoretically this design should catch everything that your nose throws out. But practically the design will causes the creation of region on the handkerchief with high density cluster of germs. Such distribution can results in uneven utilization of handkerchief spaces and likely to be difficult to be washed.

To counter with the density issue, I proposed that the handkerchief fabric materials should be chosen that allows the absorption of mucus and distribution to areas of handkerchief based on current density level.

Just another bored posting. :p
