A Data Matrix on a Mini PCI card, encoding the serial number 15C06E115AZC72983004. The most popular application for Data Matrix is marking small items, due to the code's ability to encode fifty characters in a symbol that is readable at 2 or 3 mm 2 (0.003 or 0.005 sq in) and the fact that the code can be read with only a 20% contrast ratio.

The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...
e. UTF-8 is a character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit. [ 1 ] Almost every web page is stored in UTF-8. UTF-8 is capable of encoding all 1,112,064 [ 2 ] valid Unicode code points using a variable-width encoding of one to four ...
One-hot encoding is often used for indicating the state of a state machine.When using binary, a decoder is needed to determine the state. A one-hot state machine, however, does not need a decoder as the state machine is in the nth state if, and only if, the nth bit is high.
Type–length–value. Within communication protocols, TLV (type-length-value or tag-length-value) is an encoding scheme used for informational elements. A TLV-encoded data stream contains code related to the record type, the record value's length, and finally the value itself.
Inside–outside–beginning (tagging) The IOB format (short for inside, outside, beginning), also commonly referred to as the BIO format, is a common tagging format for tagging tokens in a chunking task in computational linguistics (ex. named-entity recognition). [1] It was presented by Ramshaw and Marcus in their paper "Text Chunking using ...
Python, for example, uses the label MS-Kanji (or cp932) for Windows-932 and the label Shift_JIS (or sjis) for JIS X 0208-defined Shift JIS, without recognising the Windows-31J label. [ 12 ] In Japanese editions of Windows, this code page is referred to as "ANSI" , since it is the operating system's default 8-bit encoding, even though ANSI was ...
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which ...
