Bit Grooming Improves Precision/Compression Ratio
We developed an algorithm called Bit Grooming that significantly reduces the volume of data while retaining the desired precision and eliminating statistical biases often associated with lossy compression.
Bit Grooming reduces the storage required by 40-80% and does not require any special software to read. This allows models to export higher time-frequency or spatial resolution data without increasing storage costs.
We introduce Bit Grooming, a lossy compression algorithm that removes the bloat due to false-precision, those bits and bytes beyond the meaningful precision of the data. Bit Grooming is statistically unbiased, applies to all floating point numbers, and is easy to use. Bit-Grooming reduces data storage requirements by 25-80%. Unlike its best-known competitor Linear Packing, Bit Grooming imposes no software overhead on users, and guarantees its precision throughout the whole floating point range.
