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. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Krzyż Walecznych
The Cross of Valour () is a Polish military decoration. It was introduced by the Council of National Defense (Poland), 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.

Comecon
The Council for Mutual Economic Assistance, often abbreviated as Comecon ( ) or CMEA, was an economic organization from 1949 to 1991 under the leadership of the Soviet Union that comprised the countries of the Eastern Bloc#List of states, 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 Communism, 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.

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.

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. The machine could perform about 1 million instructions per second, making it highly competitive with the US Data General SuperNOVA and UK CTL Modular One. Most other minicomputers of the era were significantly slower. 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. Sometime later the K-202 had a successor, , hundreds of which were built. Description The K-202 was packaged in a metal box similar to other minicomputers in overall size, and capable of being fit into a 19-inch rack, which was common for other systems. Like ...

Image Recognition
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 form of decisions. "Understanding" in this context signifies the transformation of visual images (the input to 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 behind artificial systems that extract information from images. Image data can take many forms, such as video sequences, views from multiple cameras, multi-dimensional data from a 3D scanner, 3D point clouds from LiDaR sensors, or medical scanning devices.

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of Rigour#Mathematics, mathematically 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 use Conditional (computer programming), conditionals to divert the code execution through various routes (referred to as automated decision-making) and deduce valid inferences (referred to as automated reasoning). In contrast, a Heuristic (computer science), heuristic is an approach to solving problems without well-defined correct or optimal results.David A. Grossman, Ophir Frieder, ''Information Retrieval: Algorithms and Heuristics'', 2nd edition, 2004, For example, although social media recommender systems are commonly called "algorithms", they actually rely on heuristics as there is no truly "correct" recommendation.
