"Change your life for 10 consecutive holidays. It will make you an AI engineer"

I saw the ad.

I have been serializing "technology that is reworded as" AI "for two years.

However, even I, do not know what kind of job "AI engineer", and above all, I doubt whether such a job type exists.

At least to embody AI technology, you have already got the following all technologies.

- ability to speculate down formulas into programs, code, debug and evaluate

- ability for database schema design, construction, create SQL statement

- ability to grasp used memory space, and sense of scale of combination explosion

- sense of creating a viewer that visualizes the learning process

In my case, I think that "three years" was necessary to obtain each of the above processes.

It can be asserted that it was impossible in "10 days".

Even if it is not programming, but spreadsheet like Excel, honestly, I think that it is a "laughing" and a "jumping" thing that people say the word "AI" without performing variance, standard deviation, regression analysis.

(To be continued)

The other day, I found a SNS message on the Internet.

"I found a person whose name "Tomoichi Ebata". His works are very interesting. I wonder why he has not tried suiside by himself"

At first, I thuoght "what does it mean?" however, I came to mind immediately.

-----

Because all of my columns shows only

"Desperate future"

In addition, we are offering three sets of logic, numerical values, and simulation.

-----

However, I also seem strange.

So, I wondered, "Why did I not commit suicide until now, drawing a 'desperate future'?"

The answer came out quite easily (about 5 seconds).

"Until I confirm the results of your simulation with my own eyes, I never die"

That's because the thoughts lead to my attachment to life.

This is the human nature of both as an engineer and a researcher.

A few days ago, when my second daughter came out of her room and told me she had a fever, the Ebata family was on the warpath.

First of all, after contacting my family on LINE, I put up a sign saying that the upstairs bathroom was for my second daughter only, and quickly built a DMZ (or not).

I carried the mini-table for eating into the second daughter's room, and threw the bottled drinking water into the room,

She said that she had no taste disorder and had a good appetite, I didn't think that she's infected with corona, however, I took quarantine measures as soon as possible.

And,

"I brought the food to the second daughter's room, wearing a mask and lab coat"

This was a cosplay of a medical professional.

-----

After that, my second daughter's fever came down with over-the-counter medication, so I think that this case is not (probably) caused by the new coronavirus.

I think the university entrance ceremony and the unfamiliar classes must have made her tired.

In that sense, this is the time of year when the risk of infection is high.

Anyway, my second daughter, my eldest daughter, and of course, my husband and I are always at risk of unconscious infection, so we will continue to prevent infection in our home as we have in the past.

-----

However, no matter how careful we are, there will always be times when we get infected.

Infection control measures can only "reduce the probability of infection", not "prevent infection".

"Wearing a mask" only reduces the probability of infection.

Even with "masked dinners," the probability of infection increases from time to time in proportion to the duration of the meal -- This is a natural phenomenon (not even math).

Only "individuals" can "reduce the probability" -- not "governments" (except for the state, where the actions of the people can be controlled by the will of the politicians).

Many people's immune systems will be weakened in April, when a new way of life begins.

Let's be careful with each other.

The other day, when I tried to use my credit card to send money to a store in Europe after completing the order process, I was troubled by the fact that it kept getting rejected with errors.

The location of the store was not disclosed, but it might have been "that country that is under financial sanctions from all over the world".

It said, "You can also pay in Bitcoin," so I attempted the method.

I still had some money left over from a previous purchase of about $5,000 for testing.

However, the system told me, 'The balance is not enough.

I thought this was strange, so I looked into it and was surprised to find that "the cost of remittance was higher than the price of the purchased item.

I thought 'Bitcoin has low remittance costs' was the biggest selling point.

This may not have been because of the bitcoin, but because of the fees charged by the store. Anyway, I gave up on the bitcoin transfer and canceled this transaction.

-----

(1) If retail stores are force to stop using credit cards, they are going to dry up easily.

(2) Bitcoin could be used as a loophole in payment procedures.

This was a real experience of what is currently being reported in the news.

-----

I just sent "a thank you" to the person who helped me with an Amazon gift.

The procedure took 30 seconds.

"It's really, really easy."

I realize that.

Coding (programming) can get "stuck" quite often, due to bugs or confusion about API specifications.

Specialized (cult-like) field like the one I work in, I can't even find an article explaining it.

Well, that's why I publish what I have faced the problem on my blog, without 'neatly summarizing' it.

Even my garbage notes are far better than no information whatsoever.

-----

Now, this coding "getting stuck" issue is one that I get really pissed off to deal with. In the worst case, it can take up two or three full days of my time, with zero results.

To get out of this coding quagmire, we need to have the courage to "abort" it.

However, this "abort" is really difficult.

It's called "The Curse of Sunk Costs."

-----

In cases like this, I 'email questions to the experts'.

Thus, I temporarily step away from the problem.

Of course, this is a shameless method that inconveniences others and is rude in the first place.

Therefore, I must build a relationship of trust with them on a regular basis.

What is that relationship of trust? When that person asks me a question, I have to 'disclose all the knowledge I have in the fastest and unconditional way possible".

This must be done on a daily basis.

This is called "human networking".

Exchanging business cards is not "networking".

We must keep the "blood" of proper exchange of information and trust flowing through our connections.

A "networking" without "blood" is just a "tube.

-----

Conversely -- I will not intentionally (maliciously) respond to anyone who tries to use me only when they are in trouble, as I recall.

I have cut off the "tube" itself to anyone who does not send me even a single thanks mail for the information I provide.

Well, I guess you could call such a narrow-minded person 'childish', however,

As far as I know, most adults in the world are not 'childish'.

Many people say that first impressions are important in love.

I, too, agree with this.

However, I believe that first impressions are significant, not only in love but in any situation.

Based on the impression I get from the first talk, I think, 'Which persona shall I use for this person from now on?

I use several personas for the same person if necessary.

In stacked meetings, drinking parties, etc., I try to act as a completely different persona to get through the situation (although sometimes I can't).

-----

I acted as a "radical activist" when I attended for admission to the university's self-governing dormitory.

In reality, however, I had never been a "radical activist" before, and even after that, I was just an ordinary college student studying usually.

Therefore, I was called a "liar" in the dormitory.

I even played with making a "remote-controlled detonator" and verifying "hydrogen combustion."

When I did job interviews, I portrayed myself as a graduate student struggling with the difference between hypothesis and proof in an experiment.

I had a highly calculated (ulterior motive) that this persona should be attractive in the engineering company.

Nevertheless, every persona is still me.

I change the switch and volume of the persona depending on the situation.

-----

As you know, I am completely different in the column than in the office.

It is at the level of, "I wouldn't be surprised if we got into a fistfight in my mind.

But "using multiple personas" is a normal act of a normal person.

I remember the above when I remembered seeing and hearing

"the voice and expression on my second daughter's face as she was doing a remote job interview on her laptop."

In other words,

"Another daughter is possessing my daughter."
