πŸ”— Teuvo Kohonen Has Died

πŸ”— Biography

Teuvo Kalevi Kohonen (11 July 1934 – 15 December 2021) was a prominent Finnish academic (Dr. Eng.) and researcher. He was professor emeritus of the Academy of Finland.

Prof. Kohonen made many contributions to the field of artificial neural networks, including the Learning Vector Quantization algorithm, fundamental theories of distributed associative memory and optimal associative mappings, the learning subspace method and novel algorithms for symbol processing like redundant hash addressing. He has published several books and over 300 peer-reviewed papers.

Kohonen’s most famous contribution is the Self-Organizing Map (also known as the Kohonen map or Kohonen artificial neural networks, although Kohonen himself prefers SOM). Due to the popularity of the SOM algorithm in many research and in practical applications, Kohonen is often considered to be the most cited Finnish scientist. The current version of the SOM bibliography contains close to 8000 entries.

During most of his career, Prof. Kohonen conducted research at Helsinki University of Technology (TKK). The Neural Networks Research Centre of TKK, a center of excellence appointed by Academy of Finland was founded to conduct research related to Teuvo Kohonen's innovations. After Kohonen's retirement, the center was led by Prof. Erkki Oja and later renamed to Adaptive Informatics Research Centre with widened foci of research.

Teuvo Kohonen was elected the First Vice President of the International Association for Pattern Recognition from 1982 to 1984, and acted as the first president of the European Neural Network Society from 1991 to 1992.

For his scientific achievements, Prof. Kohonen has received a number of prizes including the following:

  • IEEE Neural Networks Council Pioneer Award, 1991
  • Technical Achievement Award of the IEEE Signal Processing Society, 1995
  • IEEE Frank Rosenblatt Award, 2008

πŸ”— Culinary Diplomacy

πŸ”— International relations πŸ”— Food and drink

Culinary diplomacy, gastrodiplomacy or food diplomacy is a type of cultural diplomacy, which itself is a subset of public diplomacy. Its basic premise is that "the easiest way to win hearts and minds is through the stomach". Official government-sponsored culinary diplomacy programs have been established in Taiwan, Thailand, South Korea, Malaysia, Peru, the United States, Cambodia, Japan, Scandinavia, Australia and Uzbekistan.

πŸ”— Slaughterbots

πŸ”— Film

Slaughterbots is a 2017 arms-control advocacy video presenting a dramatized near-future scenario where swarms of inexpensive microdrones use artificial intelligence and facial recognition to assassinate political opponents based on preprogrammed criteria. The video was released onto YouTube by the Future of Life Institute and Stuart Russell, a professor of computer science at Berkeley, on 12 November 2017. The video quickly went viral, gaining over two million views. The video was also screened to the November 2017 United Nations Convention on Certain Conventional Weapons meeting in Geneva.

Xsnow is a software application that was originally created as a virtual greeting card for Macintosh systems in 1984. In 1993, the concept was ported to the X Window System as Xsnow, and was included on a number of Linux distributions in the late 1990s.

πŸ”— Young's Lattice

πŸ”— Mathematics

In mathematics, Young's lattice is a partially ordered set and a lattice that is formed by all integer partitions. It is named after Alfred Young, who, in a series of papers On quantitative substitutional analysis, developed representation theory of the symmetric group. In Young's theory, the objects now called Young diagrams and the partial order on them played a key, even decisive, role. Young's lattice prominently figures in algebraic combinatorics, forming the simplest example of a differential poset in the sense of Stanley (1988). It is also closely connected with the crystal bases for affine Lie algebras.

πŸ”— Ayahuasca

πŸ”— Plants πŸ”— Psychoactive and Recreational Drugs πŸ”— Altered States of Consciousness πŸ”— South America

Ayahuasca is a South American (pan-Amazonian) psychoactive brew used both socially and as ceremonial spiritual medicine among the indigenous peoples of the Amazon basin. It is a psychedelic and entheogenic brew commonly made out of the Banisteriopsis caapi vine, the Psychotria viridis shrub or a substitute, and possibly other ingredients. A chemically similar preparation, sometimes called "pharmahuasca", can be prepared using N,N-Dimethyltryptamine (DMT) and a pharmaceutical monoamine oxidase inhibitor (MAOI), such as isocarboxazid. B. caapi contains several alkaloids that act as MAOIs, which are required for DMT to be orally active. Ayahuasca is prepared in a tea that, when consumed, causes an altered state of consciousness or "high", including visual hallucinations and altered perceptions of reality.

The other required ingredient is a plant that contains the primary psychoactive, DMT. This is usually the shrub P. viridis, but Diplopterys cabrerana may be used as a substitute. Other plant ingredients often or occasionally used in the production of ayahuasca include Justicia pectoralis, one of the Brugmansia (especially Brugmansia insignis and Brugmansia versicolor, or a hybrid breed) or Datura species, and mapacho (Nicotiana rustica).

πŸ”— Mundaneum

πŸ”— Computing πŸ”— Reference works πŸ”— Belgium

The Mundaneum was an institution which aimed to gather together all the world's knowledge and classify it according to a system developed called the Universal Decimal Classification. It was developed at the turn of the 20th century by Belgian lawyers Paul Otlet and Henri La Fontaine. The Mundaneum has been identified as a milestone in the history of data collection and management, and (somewhat more tenuously) as a precursor to the Internet.

In the 21st century, the Mundaneum is a non-profit organisation based in Mons, Belgium that runs an exhibition space, website and archive which celebrate the legacy of the original Mundaneum.

πŸ”— Yiddish Words Used in English

πŸ”— Judaism

Yiddish words used in the English language include both words that have been assimilated into English - used by both Yiddish and English speakers - and many that have not. An English sentence that uses either may be described by some as Yinglish (or Hebronics), though a secondary sense of the term Yinglish describes the distinctive way certain Jews in English-speaking countries add many Yiddish words into their conversation, beyond general Yiddish words and phrases used by English speakers.

In this meaning, Yinglish is not the same as Yeshivish, which is spoken by many Orthodox Jews, though the two share many parallels.
