Um, What Is a Neural Network?

It’s a technique for building a computer program that learns from data. It is based very loosely on how we think the human brain works. First, a collection of software “neurons” are created and connected together, allowing them to send messages to each other. Next, the network is asked to solve a problem, which it attempts to do over and over, each time strengthening the connections that lead to success and diminishing those that lead to failure. For a more detailed introduction to neural networks, Michael Nielsen’s Neural Networks and Deep Learning is a good place to start. For more a more technical overview, try Deep Learning by Ian Goodfellow, Yoshua Bengio, and Aaron Courville.

The Okinawan Language

Anybody who has studied Japanese and Linguistics will know that Japanese is a part of the Japonic language family. For many years it was thought that Japanese was a language isolate, unrelated to any other language (Although there is some debate as to whether or not Japanese and Korean are related). Today, most linguists are in agreement that Japanese is not an isolate. The Japonic languages are split into two groups: Japanese (日本語) and its dialects, which range from standard Eastern Japanese (東日本方言) to the various dialects found on Kyūshū (九州日本方言), which are, different, to say the least. The Ryukyuan Languages (琉球語派). Which are further subdivided into Northern and Southern Ryukyuan languages. Okinawan is classified as a Northern Ryukyuan Languages. There are a total of 6 Ryukyuan languages, each with its own dialects. The Ryukyuan languages exist on a continuum, somebody who speaks Okinawan will have a more difficult time understanding the Yonaguni Language, which is spoken on Japan’s southernmost populated island. Japanese and Okinawan (I am using the Naha dialect of Okinawan because it was the standard language of the Ryukyu Kingdom), are not intelligible. Calling Okinawan a dialect of Japanese is akin to calling Dutch a dialect of English. It is demonstrably false. Furthermore, there is an actual Okinawan dialect of Japanese, which borrows elements from the Okinawan language and infuses it with Japanese. So, where did the Ryukyuan languages come from? This is a question that goes hand in hand with theories about where Ryukyuan people come from. George Kerr, author of Okinawan: The History of an Island People (An old book, but necessary read if you’re interested in Okinawa), theorised that Ryukyuans and Japanese split from the same population, with one group going east to Japan from Korea, whilst the other traveled south to the Ryukyu Islands. “In the language of the Okinawan country people today the north is referred to as nishi, which Iha Fuyu (An Okinawn scholar) derives from inishi (’the past’ or ‘behind’), whereas the Japanese speak of the west as nishi. Iha suggests that in both instances there is preserved an immemorial sense of the direction from which migration took place into the sea islands.” (For those curious, the Okinawan word for ‘west’ is いり [iri]). But, it must be stated that there are multiple theories as to where Ryukyuan and Japanese people came from, some say South-East Asia, some say North Asia, via Korea, some say that it is a mixture of the two. However, this post is solely about language, and whilst the relation between nishi in both languages is intriguing, it is hardly conclusive. With that said, the notion that Proto-Japonic was spoken by migrants from southern Korea is somewhat supported by a number of toponyms that may be of Gaya origin (Or of earlier, unattested origins). However, it also must be said, that such links were used to justify Japanese imperialism in Korea. Yeah, when it comes to Japan and Korea, and their origins, it’s a minefield. What we do know is that a Proto-Japonic language was spoken around Kyūshū, and that it gradually spread throughout Japan and the Ryukyu Islands. The question of when this happened is debatable. Some scholars say between the 2nd and 6th century, others say between the 8th and 9th centuries. The crucial issue here, is the period in which proto-Ryukyuan separated from mainland Japanese. “The crucial issue here is that the period during which the proto-Ryukyuan separated(in terms of historical linguistics) from other Japonic languages do not necessarily coincide with the period during which the proto-Ryukyuan speakers actually settled on the Ryūkyū Islands.That is, it is possible that the proto-Ryukyuan was spoken on south Kyūshū for some time and the proto-Ryukyuan speakers then moved southward to arrive eventually in the Ryūkyū Islands.” This is a theory supported by Iha Fuyu who claimed that the first settlers on Amami were fishermen from Kyūshū. This opens up two possibilities, the first is that ‘Proto-Ryukyuan’ split from ‘Proto-Japonic’, the other is that it split from ‘Old-Japanese’. As we’ll see further, Okinawan actually shares many features with Old Japanese, although these features may have existed before Old-Japanese was spoken. So, what does Okinawan look like? Well, to speakers of Japanese it is recognisable in a few ways. The sentence structure is essentially the same, with a focus on particles, pitch accent, and a subject-object-verb word order. Like Old Japanese, there is a distinction between the terminal form ( 終止形 ) and the attributive form ( 連体形 ). Okinawan also maintains the nominative function of nu ぬ (Japanese: no の). It also retains the sounds ‘wi’ ‘we’ and ‘wo’, which don’t exist in Japanese anymore. Other sounds that don’t exist in Japanese include ‘fa’ ‘fe’ ‘fi’ ‘tu’ and ‘ti’. Some very basic words include: はいさい (Hello, still used in Okinawan Japanese) にふぇーでーびる (Thank you) うちなー (Okinawa) 沖縄口 (Uchinaa-guchi is the word for Okinawan) めんそーれー (Welcome) やまとぅ (Japan, a cognate of やまと, the poetic name for ‘Japan’) Lots of Okinawan can be translated into Japanese word for word. For example, a simple sentence, “Let’s go by bus” バスで行こう (I know, I’m being a little informal haha!) バスっし行ちゃびら (Basu sshi ichabira). As you can see, both sentences are structured the same way. Both have the same loanword for ‘bus’, and both have a particle used to indicate the means by which something is achieved, ‘で’ in Japanese, is ‘っし’ in Okinawan. Another example sentence, “My Japanese isn’t as good as his” 彼より日本語が上手ではない (Kare yori nihon-go ga jouzu dewanai). 彼やか大和口ぬ上手やあらん (Ari yaka yamatu-guchi nu jooji yaaran). Again, they are structured the same way (One important thing to remember about Okinawan romanisation is that long vowels are represented with ‘oo’ ‘aa’ etc. ‘oo’ is pronounced the same as ‘ou’). Of course, this doesn’t work all of the time, if you want to say, “I wrote the letter in Okinawan” 沖縄語で手紙を書いた (Okinawa-go de tegami wo kaita). 沖縄口さーに手紙書ちゃん (Uchinaa-guchi saani tigami kachan). For one, さーに is an alternate version of っし, but, that isn’t the only thing. Okinawan doesn’t have a direct object particle (を in Japanese). In older literary works it was ゆ, but it no longer used in casual speech. Introducing yourself in Okinawan is interesting for a few reasons as well. Let’s say you were introducing yourself to a group. In Japanese you’d say みんなさこんにちは私はフィリクスです (Minna-san konnichiwa watashi ha Felixdesu) ぐすよー我んねーフィリクスでぃいちょいびーん (Gusuyoo wan’nee Felix di ichoibiin). Okinawan has a single word for saying ‘hello’ to a group. It also showcases the topic marker for names and other proper nouns. In Japanese there is only 1, は but Okinawan has 5! や, あー, えー, おー, のー! So, how do you know which to use? Well, there is a rule, typically the particle fuses with short vowels, a → aa, i → ee, u → oo, e → ee, o → oo, n → noo. Of course, the Okinawan pronoun 我ん, is a terrible example, because it is irregular, becoming 我んねー instead of  我んのー or 我んや. Yes. Like Japanese, there are numerous irregularities to pull your hair out over! I hope that this has been interesting for those who have bothered to go through the entire thing. It is important to discuss these languages because most Ryukyuan languages are either ‘definitely’ or ‘critically’ endangered. Mostly due to Japanese assimilation policies from the Meiji period onward, and World War 2. The people of Okinawa are a separate ethnic group, with their own culture, history, poems, songs, dances and languages. It would be a shame to lose something that helps to define a group of people like language does. I may or may not look in the Kyūshū dialects of Japanese next time. I’unno, I just find them interesting.

The Hairstyle Of This Small Girl, Cut Short And topped With A Ribbon Bow, seems To Date This Advertisement

The hairstyle of this small girl, cut short and topped with a ribbon bow, seems to date this advertisement from the early 1950s. The printer is believed to be Whitcombe & Tombs, because the poster came to the Library with other material printed by that company.

[Whitcombe & Tombs Ltd?] :Goodness! that’s tempting. Weet-bix [ca 1954?]

If this Tibetan padlock looks massive that is because it is! And it has not one but THREE equally ginormous keys to open it! It is definitely a very intriguing padlock and indeed something of a puzzle as all three keys must be fitted simultaneously for it to open. There is one lock at the top underneath a panel, another on the side, and a third under a hinged panel on the back. Quite impressive!

We think it dates from the late nineteenth or early twentieth century and was purchased for the museum by Emslie Horniman, who was the son of our founder Frederick Horniman.

Christ The Redeemer (Portuguese: Cristo Redentor) Is An Art Deco Statue Of Jesus Christ In Rio De Janeiro,
Christ The Redeemer (Portuguese: Cristo Redentor) Is An Art Deco Statue Of Jesus Christ In Rio De Janeiro,

Christ the Redeemer (Portuguese: Cristo Redentor) is an Art Deco statue of Jesus Christ in Rio de Janeiro, Brazil, created by French sculptor Paul Landowski and built by the Brazilian engineer Heitor da Silva Costa, in collaboration with the French engineer Albert Caquot. It is 30 metres (98 ft) tall, not including its 8-metre (26 ft) pedestal, and its arms stretch 28 metres (92 ft) wide.

The statue weighs 635 metric tons (625 long, 700 short tons), and is located at the peak of the 700-metre (2,300 ft) Corcovadomountain in the Tijuca Forest National Park overlooking the city of Rio. As a symbol of Brazilian Christianity, the statue has become an icon for Rio de Janeiro and Brazil. It is made of reinforced concrete and soapstone, and was constructed between 1922 and 1931.

The statue of Christ the Redeemer with open arms, a symbol of peace, was chosen. Local engineer Heitor da Silva Costa designed the statue; it was sculpted by Polish-French sculptor Paul Landowski. Gheorghe Leonida contributed by portraying Jesus Christ’s face on the statue, which made him famous.

A group of engineers and technicians studied Landowski’s submissions and the decision was made to build the structure out of reinforced concrete (designed by Albert Caquot) instead of steel, more suitable for the cross-shaped statue. The outer layers are soapstone, chosen for its enduring qualities and ease of use. Construction took nine years, from 1922 to 1931 and cost the equivalent of US$250,000 ($3,300,000 in 2015). The monument was opened on October 12, 1931.During the opening ceremony, the statue was lit by a battery of floodlights turned on remotely by shortwave radio pioneer Guglielmo Marconi, stationed 5,700 miles (9,200 km) away in Rome.(x)

+heroes of nusantara: multatuli

YES, I, Multatuli, “who have suffered much,”—I take the pen. I do not make any excuses for the form of my book,—that form was thought proper to obtain my object…. I will be read! Yes, I will be read. I will be read by statesmen who are obliged to pay attention to the signs of the times; by men of letters, who must also look into the book of which so many bad things are said; by merchants, who have an interest in the coffee auctions; by lady’s-maids, who read me for a few farthings; by governors-general in retirement; by ministers who have something to do; by the lackeys of these Excellencies; by mutes, who, more majorum, will say that I attack God Almighty, when I attack only the god which they made according to their own image; by the members of the representative chambers, who must know what happens in the extensive possessions over the sea which belong to Holland….  

Ay, I shall be read!

Eduard Douwes Dekker was born in Amsterdam, March 2nd 1820. His father was a ship’s captain and intended for his son to have a career in trade. This humdrum prospect disgusted Douwes Dekker and in 1838 he obtained a post as a civil servant on the island of Java. During the period between 1848 and 1851 Douwes Dekker eventually rose to serve as assistant resident in various regencies in the Indonesian archipelago including Natal, North Sumatra, Manado in Sulawesi and Ambon in the Moluccas. In 1857 he was transferred to Lebak, in the Bantam residency of Java (now Banten province). By this time, however, all the secrets of Dutch administration were known to him, and he had begun to openly protest about the abuses of the colonial system. Consequently, he was threatened with dismissal from his office for his openness of speech. Douwes Dekker resigned his appointment and returned to the Netherlands.

He was determined to expose in detail the scandals he had witnessed, and he began to do so in newspaper articles and pamphlets. Little notice, however, was taken of his protestations until, in 1860, he published his novel Max Havelaar under the pseudonym of Multatuli. Douwes Dekker’s new pseudonym, which is derived from Latin, means, “I have suffered much”, or, more literally “I have borne much” referring to himself, as well as, it is thought, to the victims of the injustices he saw. An attempt was made to suppress the inflammatory book, but in vain; it was read all over Europe. Apologists for colonialism accused Douwes Dekker’s horrific depictions of being exaggerated.

[ his statue in amsterdam ]

Although it was translated into English in 1868, the text wasn’t available in the author’s home country until over a century later in 1972. Collectively, Multatuli’s Max Havelaar has been translated into 34 different languages worldwide since its initial publication. Credited as the stirring initiation of the nationalist movement responsible for the termination of Dutch colonization of Indonesia following World War II, Max Havelaar’s legacy is not confined to literary accomplishment, but can be considered a work of great political success and inspired social liberation. Max Havelaar’s influence on the national movement ultimately culminated in the passionate command to end decolonization worldwide. The story of Max Havelaar illuminates the inhumane and political injustices brutally imposed upon the native peoples of the region.

Sigmund Freud listed Multatuli as one of his favorite writers. Multatuli’s brother, Jan Douwes Dekker, was the grandfather of Ernest Douwes Dekker (also known as Danudirja Setiabudi, a National Hero of Indonesia). There is a museum for him in Amsterdam. Multatuli is also known as the person who coined the term emerald of equator, a poetic nickname of Indonesia.

This book is an introduction….  I shall increase in strength and sharpness of weapons, according as it may be necessary.    Heaven grant that it may not be necessary!…    No, it will not be necessary! For it is to thee I dedicate my book: WILLIAM THE THIRD, King, Grand Duke, Prince,… more than Prince, Grand Duke, and King,… EMPEROR of the magnificent empire of INSULIND, which winds about the equator like a garland of emeralds!…    I ask THEE if it be thine IMPERIAL will that the Havelaars should be bespattered with the mud of Slymerings and Drystubbles; and that thy more than thirty millions of SUBJECTS far away should be ill treated and should suffer extortion in THY name!

Researchers Can Identify You By Your Brain Waves With 100 Percent Accuracy

Researchers can identify you by your brain waves with 100 percent accuracy

Your responses to certain stimuli – foods, celebrities, words – might seem trivial, but they say a lot about you. In fact (with the proper clearance), these responses could gain you access into restricted areas of the Pentagon.

A team of researchers at Binghamton University, led by Assistant Professor of Psychology Sarah Laszlo and Assistant Professor of Electrical and Computer Engineering Zhanpeng Jin, recorded the brain activity of 50 people wearing an electroencephalogram headset while they looked at a series of 500 images designed specifically to elicit unique responses from person to person – e.g., a slice of pizza, a boat, Anne Hathaway, the word “conundrum.” They found that participants’ brains reacted differently to each image, enough that a computer system was able to identify each volunteer’s “brainprint” with 100 percent accuracy.

“When you take hundreds of these images, where every person is going to feel differently about each individual one, then you can be really accurate in identifying which person it was who looked at them just by their brain activity,” said Laszlo.

In their original study, titled “Brainprint,” published in 2015 in

Neurocomputing

, the research team was able to identify one person out of a group of 32 by that person’s responses, with only 97 percent accuracy, and that study only incorporated words, not images

No. 2 Construction Battalion

No. 2 Construction Battalion

Fighting for a country that didn’t want them.

On March 25 1917, Canada’s first and only black military unit left Halifax harbor for the Western Front. Six hundred soldiers, mostly from Nova Scotia, formed up as No. 2 Construction Battalion. Many had been trying to enlist since 1914,  but winning this privilege had been an up-hill fight: for two years military authorities had turned down black recruits, telling them “This is a white man’s war.”

Finally, in 1916, Canada allowed black recruits entry into a segregated united of laborers. An additional 165 African-Americans crossed the border to join them, creating a full complement of 600 men. Winning the struggle to join up hardly ended discrimination. Except for the reverend, all officers were white, and even when they went to board their transport ship on March 25 the captain initially refused to let them on, saying that he would not let them travel on the same vessel as white soldiers.

No. 2 Construction Battalion

The recruits hoped to be allowed to fight when they reached France, but instead the Canadian Expediotnary Force immediately downgraded them from a battalion to a company and assigned them to fell trees and prepare positions for white soldiers. They were not ever even issued with rifles. Their work was tedious and demoralizing, and many considered themselves failures even as they suffered casualties from artillery shells and poison gas.

The unit returned to Canada in 1919, but received no fanfare upon arrival. Much like America’s black soldiers, they returned to a country that did not value them or their sacrifice and actively oppressed their rights. Most of these veterans returned to poverty and unemployment. When they finally had their first reunion in 1982, only nine could attend from twenty known survivors. Their legacy and sacrifice has been revived since then. Although very few men were allowed the chance to serve, they began the first crack in the Canadian military’s institutionalized racism.
