Norman-evil AI

Norman-Pictures

With a commonsense, we think that the word or notion “Scientific” is a synonym to “Rational” and often (quite opportunistically) think its nature IS virtuous, while forgetting a lots of evil science like atomic bomb.  And believe that the ultimate intelligence / AI could solve all the problem of human being.  Though, same to the Great Nature, the Science and the Rationalism is value-free.  To see or use it for good or evil is completely up to us.  Now the Australian is desperately  wanting a stormy rain, even though it has been killing thousand of people in India.  The rain itself was caused and acting completely out of poor human emotion = simply, too much moisture in the air has to come down in any manner.  Even AI wouldn’t change this.  (May give better weather forecast though)  😀

AI or Artificial Intelligence will work based on the all the information and all the ideas or theories known to the human society (that’s what they says).  Then use all those data to generate the answer to the question.  (It’s a famous story, when a Chinese institute asked AI about their country,  the AI answered “You are silly to live in this country. Emigrate to Canada” — Chinese authority shut down the institute.)  So, people think that like the all-known God the AI can give the best and ultimate answer to human —– but it was found to be not necessary true. —– Like a poor human, even AI can not necessary be rational and virtuous = it could be fatally biased by the first information like us misjudge by the wrong first impression.

AI-Powered Psychopath

We present you Norman, world’s first psychopath AI. Norman is born from the fact that the data that is used to teach a machine learning algorithm can significantly influence its behavior. So when people talk about AI algorithms being biased and unfair, the culprit is often not the algorithm itself, but the biased data that was fed to it. The same method can see very different things in an image, even sick things, if trained on the wrong (or, the right!) data set. Norman suffered from extended exposure to the darkest corners of Reddit, and represents a case study on the dangers of Artificial Intelligence gone wrong when biased data is used in machine learning algorithms.

Norman is an AI that is trained to perform image captioning; a popular deep learning method of generating a textual description of an image. We trained Norman on image captions from an infamous subreddit (the name is redacted due to its graphic content) that is dedicated to document and observe the disturbing reality of death. Then, we compared Norman’s responses with a standard image captioning neural network (trained on MSCOCO dataset) on Rorschach inkblots; a test that is used to detect underlying thought disorders.

Note: Due to the ethical concerns, we only introduced bias in terms of image captions from the subreddit which are later matched with randomly generated inkblots (therefore, no image of a real person dying was utilized in this experiment).

平常心(対話から)

これは友人とのメールのやり取りの抜粋です(青字は友人)

ーーー で、かつての人生の思い出、その追憶の駒々はどんな栄光や贅沢よりも、私にとってのかけがいのない宝物なのだ。それが宝物かガラクタかは、ひとりひとりのホンネで決める、というより、決まってしまう事だ。

そんな個人ごとの宝物を死ぬまで保持することがいかに大切かを共感する人々は、決して少なくはない。

この心理をわかってくれるときが来れば嬉しい。そして、先輩が意図していること とは無関係に、このホンネの欲求に先ピンホール写真が寄り添ってくれるから、ありがたい。

ピンホール写真にやすらぎを覚えるのは、私の場合、心が覚えていて、時空を超えて再現したい、あるいは、せめて心の中にだけでも再現し再体験したい愛しき何かへの入り口を感じさせてくれるからだ。

  おたくはものすごい思ぃ入れと追憶の中で生きてて、おそらく禅も同様に思ぃ入れ、思念の形だと考ていると思う。しかし僕の禅には思込みの分は無現にやっている事、そこでの無心が僕にとっての禅であり解脱なのだ。つまり、何か特別な思い方とか観念が禅なのではなく、何の思いも無いのが褝なのだ。

何の思念、知的作意なく発想された事は、実は潜在意識、情念の深層からの呼びかけに外ならない。で、それを黙々と追求していくうちに針金彫刻ARに付いたベス単なんて物が出来上った。これが僕の禅であり自在だ。

同様に何故かボケた映像に引っかかる。待てよ、これどっかで見たぞ。いつだったかは解らない遠い昔、ひよっとしたら夢の中だったかも。---で、ツァィスレンズの向にそれを発見して以来、僕のレンズ行脚が始った。ピンホールはその一駒だ。

        *******

  執着を捨てることを良しとする賢人は古来多かれど、「自分に正直に生きる」「嘘をつかずに生きる」ことではじめて安らぎを得る人も多い。しかし現実には本音をいつわり、偽の自分を生きて幸せを装う程、器用に振る舞えない人のひとりであることをさんざん自覚させられてきた

  正直も否も執着と言った感情どころか、そもそもアタシはあまり自己である意識が無いので思いつくまま 勝手に生きさせていただいております。これ禅で言う自在。

で、自在についてもう少し書くと=これは孔子サマの言う「己れの欲する所に従えども距を超えず」と同様なもの己れ、己れの生きざま、思考、撰択の全てが一致しているなら、つまり己れとして生れたそのもの、つまりルマ、ダルマに沿ったものであるなら、それがー如であり、それが正しい。

  正直であるの無いの云々と考えているお宅はまだ正直の外側をうろうろしているだけで正直になり切っていない。(本当に正直なら、それについて考える事はない)

『俺以外の誰でもない俺は、俺である事を考る必要はない』

だから禅は考えないし(無心)自己である意識の必要も無い(無私)。只生きるだけ。---で、これが自在でありその心を平常心と呼ぶ。

お宅がごちゃごちゃ悩んでいるとしたら、お宅は悩むように生れたのかも知れぬ=それがお宅のカルマであるなら、そう生きるのが正しい

Yet another collection of Mag lens images taken around the Oxford street, London.

Sony A7R’s AWB tend to give brownish adjustment when it has too much blue sky for alien lens.

Mug'B(3)-DSC09832

Mug'B(4)-DSC09831

Strangely this lens is pretty good to create 19thC townscape paintings like image.  May be Sony’s brownish AWB was contributing to this tendency too.

Only a trouble of this Mag lens is, its effect is sometime unpredictable.  😀

.

Mug shot (1)

I’m not having any project or mission with my Mag lens still, I’ve been carrying around this lens the most.  Because this one is probably the most typical of my fuzzy homemade lens, together with a good capability of close-up shot (since its used be a magnifier.)  And to explain what and why this lens, often I demonstrate the effect of the lens by taking picture of the person.   Naturally I got a collection of portrait of those people I met in the town.

The closer the subject, the better the image quality, still it keeps fuzziness.  So, where ever I click, the product showed my fingerprint. =  That’s I like. —– When people take picture, the result looks all same.  Since, shoot same subject and use more or less the same camera = inevitably the result became same.  That is not a kind I was born to do.  = If I make something, its got to be totally unique, and nobody ever conceived kind (so, it should come to the top of google list, such as “yoshi Zappa” “Art figure St.lucia” etc ) —– (Why people are eager to sell their name is, nothing other than the name makes the difference of the work.) —– it’s hard to be an artist.

Need lens ?

Cyriacus & Julitta church 11

(Photo above by Gordon Cooper, Church Window, July 2018)

My friend cinematographer Gordon sent me the Photos he took on his holiday in the Cornwall.

While lest of us has been barely surviving in this heatwave, what a lucky guy, Gordon.  He sent photos while saying “Who need the lens” = In deed the photos were taken by the Pinhole which I made for him. —– Yes, exactly like us living without cloths, the camera can take a photo naked = without the lens.  With Pinhole.  That’s true.  I’ve been forgotten the Pinhole —– so, take them out and took some photos around.

Pin

(What I don’t like Sony A7R is, their AWB / color balance fluctuates a lot)

I got enough variety of Pinhole = this one was even fuzzier “Concentric Double Density Pinhole” = a smaller Pinhole inside of the other pinhole = create a void inside of yet another void = how can we ?.  (This is a physical and the philosophical problem.   😀 )

Pin

Need lens(4)-DSC09903

The advantage of the Pinhole is, (as long as the camera can co-op) we can take photo without bothering the focus. (= in any distance, image would have the same fuzziness which depend on the size of the hole)

Pin

Pin-A7R

So, the Pinhole convert the image into a constant pattern, almost like a paper cut-out.

Mag

And this is the comparison.  Those three photos were not Pinhole but by the Mag lens. Lens will make one focus = other than this distance, the image will be out of focus, which effect gives a feeling of the depth / three dimension.

Mag

This Mag lens image has the strong effect of the aberration together with rather messy out of focus bokeh.

Mag

On this photo, right amount of out of focus bokeh is giving a nice softness —– if this one was by the Pinhole, it would become rather messy image. = Pinhole is not necessary suit for all the subject. (better suit for bold pattern and that kind of image = in other words, for the some subjects, optical lens would make better image.  Needs lens !

Vest Pocket image on the 6×7 camera

Vest'P6x7(1)-A09A8379In the previous post, you might have seen the Vest Pocket lens’ image captured by a 35mm full size digital camera.  Though, the original size of the Vest Pocket camera was 6×9 (43mm x 65mm exact) —– so that, the image only on the cropped center wouldn’t show the full character of this 100 years old lens. —– (Strangely to say, don’t you agree this picture above looks like 100 years, even 200 years old painting ?)  

—– The fact, you must be noted is, 100 years ago then, the user of Vest Pocket camera seeing their picture contact printed on 6×9, card size B/W print.  Today’s reader of this blog can see the picture’s detail / sharpness easily enlarged, though there was no such luxury in old days = people just accept the picture made by the camera (with no focus adjustment).  As long as the picture showed the face looks like your boy, it was a good picture ! 

A funny story was,— there was a Photo-club in Japan,  namely “Vest Pocket camera appreciation club” (Ves-tan Club”/ べス単クラブ — Ves-tan stands, Single lens Vest Pocket ) of which the photo enthusiasts of the photo image made by the Vest Pocket camera was associated together.  And among the members, there was a special practice = use the camera while lens’ front hood which restricts the aperture smaller was removed (— See the previous post =  Lens was originally F6.6 but with the front hood makes it to F11). So, they appreciated the images with soft bokeh by the spherical aberration, the most.  In today’s standard, they might be branded “Otaku”  (It was almost like a religion, same to prefer the images made by the Canon or Leica lens than the Nikon, saying that the Canon shows the atmosphere / or taste (aji / 味) more, but the Nikon lens pick-up just clinical flaw of the skin.  —– mind you, this was the story of 40, 50 years ago.   😀 )  

Vest'P6x7(2)--004I mounted the lens on the Pentax 6×7 body using a camera’s body cap and tested its image character.  (You may say, 6×7 is not 6×9 though, don’t be too fanatic = it wouldn’t kill you anyway) 

Vest'P6x7(3)--003

(In order to mount the Lens unit to the body cap, an aluminium ring was cut out.  Because the lens has to be very close to the camera body, there was no space to put a focusing mechanism.  So that, the close focused image was made by adding an extension ring. )

Vest'P6x7(4)-A09A8359So, I took some photos on the 15 years old,  Fuji, Provia  ISO400 film — but exposed as ISO160 as I anticipated the film’s loss of sensitivity in time. — (Since, the lens was set to maximum F-aperture (F6.6) the image was pretty fuzzy on the 6×7 Pentax view finder too = rather difficult to see the definitive image.)

Vest'P6x7(5)-A09A8343

Vest@p6x7(6)-A09A8364

(Since the 100 years old single grass lens has no coating, image has a lot of halation as well.)

Vest'P6x7(7)-A09A8365

Vest'P6x7(8)-A09A8374

Vest'P6x7(9)-A09A8368

(Fuzzyness was created by not only its out of focus bokeh but by its aberration too.)

Vest'P6x7(10)-A09A8376

Vest'P6x7(11)-A09A8357

(In here you can see a lot of bokeh by the spherical aberration.= unlike the intentionally created bokeh of Helicoid Lens (A) or (B) kind, Vest Pocket lens’ fuzzyness looks more natural.)

Vest'P6x7(12)-A09A8381

So the painterly effect of this Vest Pocket lens looks rather subtle and looks natural. And the image has more atmosphere which gives more depth to the image too.  A depth of its image was induced by the emotional resonence (something like = I’ve seen this long time ago), not from the detailed data which will talk to the intellectual brain —– in fact, too much data in the image distract an emotional response, exactly like a noise in the music.

(Which the members of the “Ves-tan Club” most appreciated.)

Vest Pocket Lens on A7R

Vest'P(2)-DSC09800

—– If the image looks fuzzy, the lens was fully open (F6.6).  (But mind you, the original Vest Pocket camera’s image was 6×9, therefore we are only seeing its cropped center here.)

Well, Vest Pocket lens on the Sony A7R was the camera who took those photos though, behind of those, there were many more minutely blurred photos, seemed to be caused by the wobbly lens structure.  Otherwise, some photos were amazingly sharp, considering that they came from such old single glass lens !  (And it would rise a very serious question, that is, the great effort the manufacturer spending to create 10, 20 elements lenses using ED glass etc, what sort of practical significance was made ? —– of course, unless otherwise, there couldn’t be such as 14mm F1.8 lens or 18mm~400mm Zoom etc etc still, —– ? )     In reality, often, those expensive technical samples were made for demonstration purpose and made only 100 or so to display in their showroom.  In contrast to the millions of  18~55mm plastic kit lens.  Funny fact was, even after the people was made to believe that “the Larger the Better” myth suddenly changed into iPhone camera. —– It indicates that, so-called fine sharp image might be just a formality nobody actually bother. )

Kodak Vest Pocket Camera

K-Vi-014

  (Photo left = Vest Pocket A-127 camera.    Photo middle = Insert + Lens unit was pushed out. The round cup on the front panel is the Hood ring removed from the lens front.  Photo right = the half of the Vest Pocket camera was attached on the Sony A7R body)

Probably the most iconic vintage camera must be the Kodak A-127 Vest Pocket Camera.  Among the thousands of cameras, this camera was designed on the almost revolutionary “Cut the corner” philosophy.  On the surface, you might think that this camera was a toy though, actually the camera was 6×9 medium format (43mm x 65mm exact).  In today’s sense, if the camera was a medium format, it could produce quit high-resolution high quality picture —– but, you were wrong.  Virtually all the user of this camera had only seen their picture on a tiny 6×9 size contact print.  Think, how much a name-card size tiny picture could show the details ?  Imagine, to make a picture of photo-booth instant print, how many pixel was needed ?  (I guess, Kodak must have had many consumer test and found “good enough” compromise.)  The size of the picture to carry in a wallet (to show his baby or give his picture) IS 6×9 = card size.  To make 6×9 photo, lens focal length got to be at least 80 mm, and the size of the lens should be about 10mm.  So, on this Vest Pocket camera, the single glass lens was 12mm diameter though, a ring or hood which is restricting the aperture to 7.3mm was placed on front of the lens. (It’s mean, the lens was F6.6 but with the ring, F11. —– with this rather small aperture, a kind of pan-focus = focus-free was created = a bit of out focus may not to be a matter in a small print. ( = hence camera has no focus control) 

So the structure was designed in the same minimalist approach.   The camera consists  1) Outer shell    2) Insert with film gate   3) Lens / Shutter unit and the bellows to connect  Lens unit to Insert and the supporting pantograph   4) Bottom cover —– other than in the Shutter unit, very few screw was used, hence the Insert will be slide out with a simple push  (photo above middle)  Technically, Lens unit and the Insert, connected by the bellows and the pantograph can be seen as the Lens with focusing mechanism = it’s mean, just place the Lens unit / Insert to the front of a digital camera, we can make the pictures of Kodak Vest Pocket Lens, (which I did) — provided,  pantograph should be press-down to the correct point to have an image in focus. (photo right)

K-vest  F'open /  F13 ?The test shot showed rather promising results. (But shoot with an extreme  care ! —– Photo above left = the iris of the lens (without front ring) was fully open = F6.6.    The next, with the front ring which makes F11  (Photo right ) —– F6.6 showed nice softness and when it was stopped down, the image became more solid ! —–  though, the field test showed the other trouble of this optics —– because of not very solid lens support structure, they are pretty susceptive to the vibration =  image get easy to blur = considering the shutter shock made by the small lens shutter (when it was on the Vest Pocket) and the Square shutter in the A7R’s body, the effect seemed to be completely different, especially if there was a funny resonance on the wobbly pantograph  frame. So, I’ll show you the field test shot on the next post.

Brilliant London by the same Mag Lens

Bril'London(1)-DSC09497

When it was bright day, my Mag Lens (which got strongest halation among my homemade lens) would produce just like a blindingly bright image.

Bril'London(2)-DSC09499

Bril'London(3)-DSC09493

And I happen to encounter a kind of health campaign appearing to the pensioner.

Bril'London(4)-DSC09496

Funny paradox was that the people coming out to shout were very healthy talkative people.

Bril'London(5)-DSC09494

Bril'London(6)-DSC09495

Funny character of  Mag Lens is, under certain condition, it produces rather solid image.

Bril'London(7)-DSC09502

So, the difference = brilliant or gloomy was, which kind of the day, I go out.    😀

Gloomy London = Seen by Mag Lens

Some pictures of the London = According to the Mag Lens view.

Gr'London(1)-DSC09382

When the image is murky and dark, it will be seen as Gloomy, and this is it.   And it happen to be quite close to my own view as well. (Zennists are not so optimists though they are not necessary having a gloomy life = simply it is just not funny.  —– I can’t understand why people excite about kicking the ball or the ball on the line ?  —– What that ball to do with the person ?   We are nothing to do with the ball, do we ?    😀 )

Mag Lens doesn’t necessary make the things gloomy.  The image was just murky = hence if it was dark days, it become awfully gloomy. (I’ll show you the opposite case in the next post.)   😀
