Weak classifiers with strong logic (weak classifiers with strong logic)

Classification of non-rigid objectives

The previous column story told (
No. 20 weak classifier and strong classifier) how integrated multiple weak classifiers reorganize themselves into a strong and flexible classifier.

Traditionally, engineers merely focused on specific targets that were easy to describe with numbers or were repeatedly observable. if, however, the target is not observable, or difficult to observe, how do we define the target? This time we focus on
A conceptual or historical target whose description is often incomplete or observable only once. Even using this fuzzy target, you may notice that the concept of weak classifiers is a powerful framework.

We will first try to select a person with good personality using weak classifiers. traditional methodology requires that "good personality" be defined, which is not easy. without defining the object, it is difficult to design the classifier. however,
If we can divide the feature into partial sub-features, the classification process becomes easier to manage. the features of a good personality cocould be expressed as a person who (1) has no biased opinions, (2) regards himself/herself equally with others,
(3) does not impose on others, (4) is a good listener, (5) maintains temperate behavior, (6) is not offensive to others. none of these features is strong enough to describe a good personality by itself, but taken together, the extracted personality is expected
To be something close. to be stable, each classifier shoshould be independent. by integrating these weak classifiers, a high performance Classifier System can be obtained. the individual weak classifiers can be used with the simple logic "if a, then B ". figure
1 shows the relationships between individual statements and the resulting statement, where the central common area represents the logical statement satisfied by all weak conditions. figure 2 is another dimo-of the common region satisfied by all the independent
Conditions: α, β, Gamma. The person who passes all tests from (1) to (6) shocould be a good person.

Fig. 1. Areas A-E depict the logical regions on which when weak pieces
Of evisponstand. The center is the common area.

Fig. 2. The Cube represents an area that has common but independent
Properties, α, β and Gamma.

According to a theorem of logic, the statement "if not B, then not a" is always correct "if a, then B" is correct. this theorem is called contraposition. even when the classifier is weak, this classifier shocould be valid. to check the validity of
Weak classifiers, the contraposition theorem is helpful. it is a good idea to test this contraposition before accepting the statement that (1) "A not non-biased person does not always have a good personality."

Application to historical interpretation

The deduction, based on weak but cannot pieces of evidence has been used for policyears in the field of history or Anthropology. for example, mythology is thought to be man-made fiction with no realistic background, because it starts from God. however,
It is unrealistic to believe that a story can be created without any background. if the story is shared by groups of people, it is more reasonable to guess that the story may have some common historical background. here, I present one example of a folk tale
Inherited by the local people where I was born.

I was born in the area calledKibi, Located in the western part of Japan.SojaIs the current dominant city in this part of Okayama Prefecture. A large fortress ruins, a few kilometers in size, called Kino Jo (dedevil's
Fortress), boasts the following folk tale:

• • 1. The group was led by a princeKudara, An internal ent state in the south of the Korean peninsula. His wife was PrincessAzo.
  • 2. The prince lived in Kino Jo and annoyed nearby people with criminal acts, who gave him the name dedevil prince.
  • 3. The Government decided to send troops, led by GeneralKibitsuhiko, To conquer the dedevil prince.
  • 4. After creating difficulties,KibitsuhikoFinally won the battle.

Here is my hypothesis;"The dedevil Prince was a leader of a group that immigrated from kudara."

Following is a list of historical facts and findings.

• • 1. The shrine calledKibitsu JinjaEnshrinesKibitsuhiko, And keeps the tradition of the prophecy using the dedevil's Kettle. This job is done by females from nearbyAzoVillage, located at the foot of Kino Jo.
  • 2. The StateKudaraExisted from the 4th century to the 7th century in the southern part of the Korean peninsula. it was crushed just after the allied forces of kudara & Japan were defeated by the allied forces of Tang & Shilla in
    660 ad.
  • 3. WhenKudaraWas crushed, named people, including royal families, immigrated to Japan.
  • 4. kudara's main business was thought to be iron related.
  • 5. Around the 7th century, iron ore aroundKudaraWas depleted.
  • 6. Large scale iron production in Japan started inChugokuRegion; As a result much waste was dumped inSetoInland sea, where the white shoreline became a symbol
    SetoSea scenery. Later, the iron production area moved to the north, where much sand flooded the shoreline of the Japan Sea, creating the unique scenery of sand dunes and sandbars.
  • 7. Today, the remains of specified iron furnaces dating back to the 6th and 7th century can be found aroundAzo, As well as century 5th century Korean style ceramics.
  • 8. Ruins ofKino joFortress are a constant reminder of specified ent Korean style design.
  • 9. login ent Japanese poems often have the prologue,Magane Fuku, Meaning IronFurnacing, Followed by the Region
    Kibi.

The large scaleKino jo, Which has never appeared in historical literature, exhibits attributes of the facts listed above. Combined with historical tales of that era, here is my storyKino jo:

The specified ent state of kudara was born with its innovative technology of iron furnaces. after several hundreds of years, the iron ore ran out. with the superior technology of iron furnaces, the population immigrated to western Japan,
Where they built a strong and wealthy community that sometimes competed with the Japanese Government. Kino Jo was the headquarters of the community.

I once asked an acquaintance, "mr. kudara, are you a descendant from the kingdom ofKudaraRoyal Family? ", His answer was" yes, I am ."

Epilogue

I was deeply impressed by the book seven daughters of Eve written by Bryan Sykes. my wife sent our tissue samples to Oxford Ancestors to have our mitochondrial DNA analyzed. here is one result of the analysis, which tells a very interesting story
My wife's ancestorSachi.

When I: The Great godmother
Your DNA sequence, which is very rare among native Europeans, is found in East Eurasia and the Americas. You are a direct maternal descendant of parameter I, the most frequently encountered clan in Japan.
When I's descendants are found throughout Japan today, from Hokkaido in the north to Okinawa in the south. they probably first arrived early in the history of Japan, crossing from the Asian mainland about 12,000 years ago, but later migrations, for example those
Associated with the yayoi culture, wocould also have included other descendants of each I.
Your I's descendants have also been found in mainland Asia (Siberia, China, Taiwan, Korea, Vietnam and Thailand) and in both North and South America. very occasionally her clan can be found in Europe. her descendants reached the islands of the Philippines and
Indonesia, from where they set sail to Madagascar. Further out into the pacpacific, Then I's descendants are found in Fiji and the islands of Micronesia.
From the features of this geographical distribution of her descendants we believe that grants I herself lived in Central Asia, probably at least 20,000 years ago. we will become more certain of this as more research is done in the countries of Asia, including
Japan.
Thank you for your custom and congratulations on finding your place on the world's largest family tree.

As the story reveals, most Japanese today may have an ancestral connection with the Mainland if we look back 2000 years. during its long history, several waves of immigrants groups with different cultural backgrounds arrived on Japan shores. one
The groups may beKudaraGroup, who settled aroundKino jo.
