Data compression encoding
Is encoder used for data compression?
The encoder compresses the data from a higher-dimensional space to a lower-dimensional space (also called the latent space), while the decoder does the opposite i.e., convert the latent space back to higher-dimensional space..
Text compression techniques
Data Encryption uses an encrypted code to transform the data into a secure form.
Data Compression uses an encoded code to reduce the size of the data.
Data encryption does not reduce the size of data; in fact, it may slightly increase the size of the data..

What is data compression coding?
Data compression is the process of encoding, restructuring or otherwise modifying data in order to reduce its size.
Fundamentally, it involves re-encoding information using fewer bits than the original representation..
What is data compression coding?
The process of reducing the size of a data file is often referred to as data compression.
In the context of data transmission, it is called source coding: encoding is done at the source of the data before it is stored or transmitted..

What is the difference between compression and encoding?
Overall, think of compression as an extension of encoding that's useful if your files are too large.
For most users, they may as well be the same thing.
Given some data that you want to present to the user, Encoding is the way you represent that data in a file or stream..

- In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation.
Compression can be either lossy or lossless.
Encoding.
Encoding is the process of changing data representation.
Fundamentally, it involves re-encoding information using fewer bits than the original representation. Compression is done by a program that uses functions or an algorithm to effectively discover how to reduce the size of the data.
Adjacent characters (tokens) merge-based compression algorithm
Byte pair encoding is an algorithm, first described in 1994 by Philip Gage.
Its modification is notable as the large language model tokenizer with an ability to combine both tokens that encode single characters and those that encode whole words.
This modification, in the first step, assumes all unique characters to be an initial set of 1-character long n-grams.
Then, successively the most frequent pair of adjacent characters is merged into a new, 2-characters long n-gram and all instances of the pair are replaced by this new token.
This is repeated until a vocabulary of prescribed size is obtained.
Note that new words can always be constructed from final vocabulary tokens and initial-set characters.
Streaming data transfer mechanism in HTTP/1.1
Chunked transfer encoding is a streaming data transfer mechanism available in Hypertext Transfer Protocol (HTTP) version 1.1, defined in extiw>RFC 9112 ยง7.1.
In chunked transfer encoding, the data stream is divided into a series of non-overlapping chunks.
The chunks are sent out and received independently of one another.
No knowledge of the data stream outside the currently-being-processed chunk is necessary for both the sender and the receiver at any given time.
Delta encoding is a way of storing or transmitting data in the form of differences (deltas) between sequential data rather than complete files; more generally this is known as data differencing.
Delta encoding is sometimes called delta compression, particularly where archival histories of changes are required.
Incremental encoding, also known as front compression, back compression, or front coding, is a type of delta encoding compression algorithm whereby common prefixes or suffixes and their lengths are recorded so that they need not be duplicated.
This algorithm is particularly well-suited for compressing sorted data, e.g., a list of words from a dictionary.
Form of lossless data compression
Run-length encoding (RLE) is a form of lossless data compression in which runs of data are stored as a single data value and count, rather than as the original run.
This is most efficient on data that contains many such runs, for example, simple graphic images such as icons, line drawings, Conway's Game of Life, and animations.
For files that do not have many runs, RLE could increase the file size.
