#Silo effect
Silo means a large tower -shaped warehouse that stores grain in advance. Oh, why have you ever seen a large amount of traffic in the middle of a large field? That is silo. Silo contains harvested grains, each of which exists independently, making it not mixed with each other. The advantage of silo structure is that even if a problem occurs in one silo, there is no damage to the other silo at all.
In the shape of this silo, the concept of silo effect was created. Silo effect means a situation in which each part of a organization or structure is blocked by each other. A typical example is the occurrence of silo effect due to department selfishness in the company. As shown below, each department argues only for the internal interests of the department, with silent each other, so the company’s overall communication is not as good as arteriosclerosis and eventually becomes impossible to innovate and develop business.
# Two silks that interfere with the quant business
Basically, the effect of silo effect in any kind of business is not good. This is evidence that there is no communication and innovation. In quant businesses, the occurrence of this silo effect is no wonder. In particular, the quant business has its own features, unlike other businesses, which are unique to the quant business, which causes more damage to the quant business. In more seriously, if a silo phenomenon occurs in the quant business, it means that it is almost impossible to develop the quant business from a long term.
What is the silo that hinders the development of the quant business? There are two main types of silo, which is poisonous in the quant business. One is silo by asset group, and the other is the silo between the quant.
# Silo vs. by asset group Cross Asset Perspective
The first is silo by asset group.
Quant investment’s profit is basically a casino. Be careful. Quant Business is an entrepreneur who runs a casino, not a player who plays in a casino. The business model that runs a casino is actually very simple. The casino must have some chance of an advantage over the player. After that? Nothing. The next thing you need is to increase N, that is, the number of trials to realize the law of algebra. Increasing the number of trials is, of course, the probability advantage is realized by the laws of the algebra. In other words, the expected price is actually stuck in real profits. The casino gains a slightly probable advantage, gaining a stable business revenue by dealing with numerous players.
The goal of the quant business is the same as the casino business. It is the core of the quant business to secure as many factors that are not relevant to each other and generate stable profits in the long run with the law of algebra. This can be explained in only one equation. Below is a performance equation applied to all kinds of active investment. Where IR (Information Ratio) is a performance, the information coefficient (IC) is a skill, and B (Breadth) means the number of assets or strategies. The tomb of quant investment is to increase B to enjoy the fruit made by the law of algebra.
So how can you increase this width in the quant business? The answer is simple. You can increase the number of assets and strategies that can be dealt with. But think about it. What if the silo of each asset group occurs in this situation? Naturally, the business is stopped before the laws of the algebra are realized.
Therefore, if there is a constraint of the asset group that can be handled, the quant business becomes very difficult. In other words, the system that makes a profit as a quant model is eliminated in the situation that returns to silent structure such as stock teams, bonds, foreign exchange teams, and derivatives. Therefore, the quant business must be approached from a cross -asset point 바카라 of view. The goal of the quant business is based on independence between factors and MECE structure. The quant business, which assumes the laws of algebra at the moment of gaps, will be in a headwind.
#Ms. Quant team as a production line
The second is the silo between quants. So far, traditional investment managers have made decisions in a silent structure. Since the market prospects, views, and so -called intuitions they think of each other were different, silo structure was rather beneficial from the company’s point of view. This is because the company’s diversification investment was possible at the company level. The company was able to eat and live by discovering only a few capable star fund managers. In the above equation, he focused on maximizing a few ICs.
However, it is virtually impossible to quant business with the same method. Why? Let’s think about it. Quant is basically data-driven investment, which requires multiple functions. For example, data curation, feature engineering, strategy design, backstesting, live deployment, and portfolio oversight. In addition, these functions should not play separately, but rather connect to each other and return to a series of systematic systems. But is there a quant that can perfectly digest all these things? The word to digest all of these is like a figuratively that you can work alone from the beginning to the end of the car production line. If this was possible with the same productivity, human history would have entered the Industrial Revolution.
Thus, creating a quant team should not be a structure of gathering so -called players together and fighting, and with the Roth Allamos Institute, which used the old Manhattan project. Modern great scientific discoveries were all possible because of these research units as a team.
# Punishment of Silo and Sisif Myth
Professor Marcos Lopez de Prado, which has become the standard for financial machine learning, compares silent situations in the quant area to the punishment of the Sieg mythology. In ancient Greek mythology, Sisype is punished to repeat the anger of the gods constantly to lift a large rock over the mountain and roll down again. This punishment is to repeat hard and meaningless things.
Therefore, Professor Prado argues that the quant business must remove the effect of silo, which was prevalent in traditional investment business in order not to be punished by the Sisif Myth. All successful quant companies are all chosen as the structure of the production line or the research institute, not silo structure.
The truth of what you are doing for members and fans
The article on evidence is pasted (posted) at the end. (I borrowed from Meyou’s blog.)
*****************************
Ningen observation monitoring
* This is fiction.
His outdoor restaurant on the sunset beach in Okinawa
A suspicious character wearing a Haranishi gorilla -like cover …
The customer is curious but curious.
When the food is served and the customer is enjoying the meal
… The venue announcement is.
“Welcome to Sunset Beach Restaurant today!”
Haranishi Gorilla -style character is approaching her.
Tsukasa “What? What happened? What? I want to play the piano?”
Go “…” (nodded)
Tsukasa “Can you play with that finger?”
Go “…” (Heat your chest)
Tsukasa “Do you want to do it?” “Are you all right?”
Customer “?” (Applause)
Sanceted beach has some crystal piano for some reason.
Go: (The song that I started playing was the Moonlight Daiichi Movie!)
Customer: “No way ~”
The sunset illuminates the crystal piano.
Go: I fall tears and tears, but I can’t see it because of 휴대폰바카라 the cover.
Customer: “No way ~” “Who ??”
Go: “I’m actually a pianist. I’m also playing songs. I’ll play my song from now on.”
Customer: “Shinken ??”
Go: Start playing Forever Love.
Customer: “No way ~” “YOSHIKI ???”
Go: The tears of the customer face tears, but they are invisible because of the cover.
And … I’m so impressed … I make a mistake.
Customer: “Oh?” “I made a mistake? I was saying my song.”
“Shinken?” “Isn’t it YOSHIKI?”
In fact, it does not happen like this.
Such a scenario is rejected.
There is no OK a scenario that damages your beauty.
Nevertheless, the scenario that made a mistake in playing “Forever Love” was too rude.
It’s impossible for a pianist, but it’s a finger dressed as a gorilla.
This time, I would like to think about the Haranishi gorilla style “breaking the drum” version.
* I’m sorry to refer to Haranishi Gorilla. I love Haranishi Gorilla monitoring. Haranishi is just a professional.
He is different from those who do not complete the work by repairing only the surface.
“YOSHIKI Surprise Operation”
“Advented to YOSHIKI monitoring”
A plan to surprise the reunion with Kotaro Koizumi for the first time in about 20 years.
Kotaro, who was working part -time there when the Hide Museum was created.
At that time, he met YOSHIKI in the special tent behind, and then said to the person with him, “He should be in the entertainment world.”
Kotaro, who has been working hard with the words, is impressed by the reunion with YOSHIKI for the first time in about 20 years.
Surely you will meet your father, Junichiro Koizumi.
I felt that Kotaro’s tears were real.
However, a considerable part of this surprise project was used for YOSHIKI’s own advertising.
While playing the video of “We are X”
① Won the world’s three major halls for the first time as Asians
Madison Square Garden
Carnegie Hall
Wembley Arena
(By the way, the two of these are achievements as X JAPAN)
② Respect from many artists, regardless of domestic and overseas
(Paul McCartney) (BTS)
③ Fashion icon that decorates the cover of the first Japanese man VOGUE JAPAN
④ YOSHIKIMONO was used for the closing ceremony of the Tokyo Olympics! *
⑤ Baccaratly selected as his 180th anniversary designer
⑥Y by YOSHIKI
⑦ Coca -Cola Real Gold XY
⑧ Rakuten Card YOSHIKI Design
It was a familiar advertising content, but it was a little caught
* ④ Used for the closing ceremony of the Tokyo Olympics
I moved to the next topic, but that? I thought and looked it up.
On YOSHIKIMONO Official Twitter (2021/8/9)
“YOSHOO News has been featured in Yahoo News that YOSHIKIMONO was used in the Tokyo Olympics closing performer costumes.”
There was a link, but the linked article was already deleted.
There were no other articles that seemed to be a hot topic.
I understand the enthusiasm that I wanted to get involved in the Tokyo Olympics, but don’t be too persistent.
This monitoring did not have any particular YOSHIKI’s performance.
(Ah! There was a challenge for piano performance and Mario game!)
When the content is roughly summarized
○ Surprise to Kotaro Koizumi by “YOSHIKI Advent”
○ Madame Tasseau’s descent from behind the wax form. Surprise the performers.
○ YOSHIKI’s brilliant career (all of the achievements of X JAPAN)
○ Promotion of projects and products currently ongoing
○ Challenge Super Mario
By the way, “Forever Love”, who played for Kotaro in a surprise, would have noticed that anyone who knew the song made a mistake.
As expected, the person himself explained after the performance. “When I saw Kotaro’s face, I was nervous and made a mistake.”
Did you play thousands of times? This song.
It’s a pianist who was nervous and made a mistake.
One thing was unpleasant.
The story of the old heroism.
He seems to have never seen monitoring (is it true? Are you checking Toshl’s appearance programs?)
He likes to surprise people.
“In the past, X JAPAN did not increase the tension, so I broke the drum in the first song and returned. The members panicked. Nobody knows. The staff knew, but I really thought they would do it. I didn’t. “
⇒ YOSHIKI, a surprise lover
I was really angry with this.
The first song was destroyed by the drum and the live was interrupted by DAHLIA TOUR.
“DAHLIA” recording itself has an incredible feeling, but a tour was held by a close departure.
I think it was a time when the members were jerky.
At that time, he broke the drum and left because it was the first day of the tour.
The person himself is saying something that is selfish, such as being surprised, a stunning device, or tightening the members, but the live was interrupted due to this action. The customer was waiting for about 30 minutes until the drum set was replaced with a new one and it was resumed. (Normal driving if the start of live is delayed for hours)
It is not just for customers who bothered. Both members and staff.
About 27 years.
It is only uncomfortable to talk happily as a heroic biography in the program.
“Looking back, I think I did something terrible. I was sorry for the customer at that time. I’m sorry, and I really reflect on the fact that the members have done something wrong. “
I apologize!
How does this person appreciate what he has done? Will he never reflect on him until he dies?
It’s okay to wait for the customer.
The rehearsal is a good idea.
Recording swings the members depending on their own convenience.
At the end of the clause, the release of the album for over a decade is up to you.
There are still more …
I will spare money to raise myself.
Since the album does not appear, the members have no distribution of profits.
X JAPAN’s past achievements are monopolized.
Rakuten clutch fundraising is monopolized.
In the shade, I do things that seem to be bullied against the members.
He does not keep his promise (what he stated).
Ignore if it becomes inconvenient.
… Busy, not sleeping, sick, helped someone… What should I do?
There is still … Oh, I’m tired
In this monitoring, Tatsuya Ishii of the US CLUB finally performed his own song, “You are just there.”
Those who were listening are tears, tears …
In the case of Toshl, you can tell that you are Toshl just by listening to the voice without having to make it look.
But why don’t you sing your own song (X JAPAN song)? can not sing?
… Everyone thinks so.
TV officials and performers … I don’t want you to be deceived by the brilliant background, beautiful words and narratives that YOSHIKI will show off.
What do he do to create beautiful images and great achievements …
I want you to know the truth of what you are doing to members and fans.
