Data Compression Strategies Table 27-1 shows two different ways that data compression algorithms can be categorized. In (a), ... This is absolutely necessary for many types of data, for example: ...

Lossless data-compression programs search through documents for redundant or repetitive data and then encode it. For example, a text document may contain 200 empty spaces, 100 instances of the ...

Note, however, that in my example, the topics are just more data and they change too so that would be harder in that particular case. My point is that there are many ways you could approach this ...

For a list of compression methods, see codec examples. See JPEG , GIF , MPEG , MP3 , G.7xx and interframe coding . #2 - Compressing a Group of Files (Archiving) ...

In the lossy compression of a sound file for example, the data removed might be sounds that the human ear is unable to hear, making the loss of quality as small as possible.

Machine learning models—especially large-scale ones like GPT, BERT, or DALL·E—are trained using enormous volumes of data.

An example of when you would want lossless data compression, even if it means that you have to store more data, is when you’re compressing data that originates from a database.

[Part 2 examines delta encoding and the LZW compression techniques used in GIF files. For more on image and video compression, see How Video Compression Works]. JPEG Many methods of lossy compression ...

We have already discussed a simple method of lossy data compression, coarser sampling and/or quantization (CS&Q in Table 27-1). This involves reducing the number of bits per sample or entirely discard ...
