Jacek Karpiński
Jacek Karpiński (9 April 1927 21 February 2010) was a Polish pioneer in computer engineering and computer science. During World War II, he was a soldier in the Batalion Zośka of the Polish Home Army, and was awarded multiple times with a Cross of Valour. He took part in Operation Kutschera (intelligence) and the Warsaw Uprising, where he was heavily wounded. Later, he became a developer of one of the first machine learning algorithms, techniques for character and image recognition. After receiving a UNESCO award in 1960, he travelled for several years around the academic centres in the United States, including MIT, Harvard, Caltech, and many others. In 1971, he designed one of the first minicomputers, the K-202. Because of the policy on computer development in the People's Republic of Poland, belonging to the Comecon that time, the K-202 was never mass-produced. Karpiński later became a pig farmer, and in 1981, after receiving a passport, emigrated to Switzerland. He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turin
Turin ( , Piedmontese language, Piedmontese: ; it, Torino ) is a city and an important business and cultural centre in Northern Italy. It is the capital city of Piedmont and of the Metropolitan City of Turin, and was the first Italian capital from 1861 to 1865. The city is mainly on the western bank of the Po (river), Po River, below its Susa Valley, and is surrounded by the western Alps, Alpine arch and Superga Hill. The population of the city proper is 847,287 (31 January 2022) while the population of the urban area is estimated by Larger Urban Zones, Eurostat to be 1.7 million inhabitants. The Turin metropolitan area is estimated by the Organisation for Economic Co-operation and Development, OECD to have a population of 2.2 million. The city used to be a major European political centre. From 1563, it was the capital of the Duchy of Savoy, then of the Kingdom of Sardinia ruled by the House of Savoy, and the first capital of the Kingdom of Italy from 1861 to 1865. T ...

Krzyż Walecznych
The Cross of Valour ( pl, Krzyż Walecznych) is a Polish military decoration. It was first introduced by the Council of National Defense on 11 August 1920. It is awarded to an individual who "has demonstrated deeds of valour and courage on the field of battle." It may be awarded to the same person up to four times.The only soldier ever to receive more than 4 Crosses of Valour was Stefan Grot-Rowecki, commander of the Polish Home Army during World War II, who had reached his quota of 4 crosses during World War I and the Polish-Soviet War, yet was awarded 4 more crosses on 1 May 1943. See: The medal is given only in wartime or shortly after.Zdzislaw P. Wesolowski, ''Polish Orders, Medals, Badges and Insignia: Military and Civilian Decorations, 1705–1985'', pp. 22–24, 41–42, 58. History Polish-Soviet War The medal was introduced in 1920 at the height of the Polish-Soviet War, shortly before the climactic Battle of Warsaw. Initially it had no Order Council and was awarded ...

Comecon
The Council for Mutual Economic Assistance (, ; English abbreviation COMECON, CMEA, CEMA, or CAME) was an economic organization from 1949 to 1991 under the leadership of the Soviet Union that comprised the countries of the Eastern Bloc along with a number of socialist states elsewhere in the world. The descriptive term was often applied to all multilateral activities involving members of the organization, rather than being restricted to the direct functions of Comecon and its organs. This usage was sometimes extended as well to bilateral relations among members because in the system of communist international economic relations, multilateral accords typically of a general nature tended to be implemented through a set of more detailed, bilateral agreements. Comecon was the Eastern Bloc's response to the formation in Western Europe of the Marshall Plan and the OEEC, which later became the OECD. Name in official languages of the members History Foundation The Comecon was fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Computing In Poland
The history of Polish computing ( informatics) began during the Second World War with breaking the Enigma machine code by Polish mathematicians. After World War II, work on Polish computers began. Poles made a significant contribution to both the theory and technique of world computing. In the State Institute of Mathematics, established in 1948 (from 1952 at the Polish Academy of Sciences), it was decided to start prospective work on the construction of at least one machine comparable to the American ENIAC. For this purpose, the Mathematical Apparatus Group of this Institute (''pol. Grupa Aparatów Matematycznych, GAM'') was established. The first engineering employee of GAM was , and shortly after he was joined by his fellow students, Romuald Marczyński and Krystyn Bochenek. Logician and statistician Henryk Greniewski became the head of GAM. There were no resources to build such a computer - neither technical facilities, nor electronic equipment, nor experience. The only chanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
K-202
K-202 was a 16-bit minicomputer, created by a team led by Polish scientist Jacek Karpiński between 1970–1973 in cooperation with British companies Data-Loop and M.B. Metals. Approximately 30 units were claimed to be produced. All units shipped to M.B. Metals were returned for service. Due to friction resulting from competition with Elwro, a government-backed competitor, the production of K-202 was blocked and Karpiński thrown out of his company under the allegations of sabotage and embezzlement. The K-202 had two main rivals Data General SuperNOVA minicomputer (United States) and the CTL Modular One (United Kingdom). Some time afterwards, K-202 had its successor, , hundreds units of which were built. New features The K-202 was capable of running about one million operations per second; however, its instruction set was not well suited to the typical tasks, making practical performance somewhat lower. The communist world was in a different place than the capitalist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Image Recognition
Computer vision is an interdisciplinary scientific field that deals with how computers can gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to understand and automate tasks that the human visual system can do. Computer vision tasks include methods for acquiring, processing, analyzing and understanding digital images, and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information, e.g. in the forms of decisions. Understanding in this context means the transformation of visual images (the input of the retina) into descriptions of the world that make sense to thought processes and can elicit appropriate action. This image understanding can be seen as the disentangling of symbolic information from image data using models constructed with the aid of geometry, physics, statistics, and learning theory. The scientific discipline of computer vision is concerned with the theory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Character Recognition
Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image (for example: from a television broadcast). Widely used as a form of data entry from printed paper data records – whether passport documents, invoices, bank statements, computerized receipts, business cards, mail, printouts of static-data, or any suitable documentation – it is a common method of digitizing printed texts so that they can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as cognitive computing, machine translation, (extracted) text-to-speech, key data and text mining. OCR is a field of research in pattern recognition, artificial intellige ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific Computational problem, problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a Heuristic (computer science), heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
