A cascade of processing units or hidden layersįor each of the color regions represented in the original matrix input (left), the top right filter pulls the maximum value of that region and creates a new output matrix this is the most common pooling method utilized.Advances in computing power so that large amounts of data can be quickly analyzed have made the application of AI to huge, complex data sets feasible.ĭeep learning architectures have been applied to diverse fields such as speech recognition, social network filtering, bioinformatics, drug design and medical image interpretation.ĭeep neural systems comprise a series of layers: They operate within a restricted range of pre-defined functions to accomplish narrowly demarcated tasks.ĭeep learning ― strong AI ― is one of a family of machine learning methods based on learning data set representations. These and most other devices utilize weak (narrow) AI. iRobot Roomba, which vacuums the floor and can navigate around obstacles.Some common examples of machines that utilize versions of AI include: Study results were published in Nature Medicine in 2019. Retrieved 18 October 2013.The collaborative Mayo Clinic cardiovascular AI team recently published the results of their study utilizing AI electrocardiogram (ECG) analysis to predict the presence of left ventricular dysfunction in asymptomatic patients. "First Steps in Computer Chess Programming". ^ Spracklen, Kathy and Dan (October 1978)."Oral History of Kathe and Dan Spracklen" (PDF). The Spracklens concurrently wrote the engines for the dedicated chess computers produced by Fidelity Electronics, which won the first four World Microcomputer Chess Championships. Legacy Īfter the demise of Hayden Software, later chess programs were also released under the name Sargon, including Sargon IV ( Spinnaker Software), Sargon V ( Activision) and a CD-i title simply named Sargon Chess. Apple contacted the Spracklens and, after a port for 68000 assembly, Sargon III was the first third-party executable software for the Macintosh. It was commercially published for other computing platforms by Hayden Software in 1983. He sold the publishing rights to Hayden Software for the Radio Shack TRS-80 platform. Lohnes, as self taught computer enthusiast while he was still in the US Navy. In 1978, Sargon was converted to Z80 neumonics/assembler code by Paul H. This third version was written originally for the 6502 assembler. Also included was a chess opening repertoire. Instead of an exchange evaluator, this version used a capture search algorithm. In December, 3.0 easily won the second microcomputer championship in London. The competition had improved, but 3.0 drew against Cray Blitz and easily defeated Mychess, its main microcomputer rival. Sargon 3.0 finished in seventh place at the October 1979 North American Computer Chess Championship. It received a 1641 rating at the Paul Masson tournament in June–July 1979, and 1736 at the San Jose City College Open in January 1980. Sargon 2.5, sold as a ROM module for the Chafitz Modular Game System, was identical to Sargon II but incorporated pondering. He often beat the program at level 3-when it considered moves for about two minutes-and stated that "Level 0 is an idiot but responds instantly". Mishcon reviewed Sargon II in the October 1980 issue of The Space Gamer magazine, stating that the program beat him regularly on level 5, which took 40 minutes per move. The Spracklens made significant improvements on the original program and released Sargon II. A complete rewrite was necessary later for the Apple II, programmed by Kathleen's brother Gary Shannon. In the early 1980s, SARGON CHESS was ported to the Nascom (by Bits & PCs, 1981), Exidy Sorcerer, and Sharp MZ 80K. Paul was not involved in further refinements to the TRS-80 version due to his reassignment to sea duty shortly after signing the deal with Hayden Software. Paul consulted with the Spracklens, who were both living in San Diego at the time, to make the TRS-80 version an instant success with the help of Hayden Book's newly established software division: Hayden Software. When magnetic media publishing became widely available, a US Navy petty officer, Paul Lohnes, ported Sargon to the TRS-80, altering the graphics, input, and housekeeping routines but leaving the Spracklens' chess-playing algorithm intact.
