Abstract
One example method includes at a source, at a source, performing a symbolic aggregation process on a series of raw data generated and/or collected by the source, to create a series of symbols, inputting, by the source, the series of raw data and the series of symbols to a lossy compression algorithm operating at the source, running, at the source, the lossy compression algorithm to obtain a series of raw values, and a sparse series of raw values, and transmitting, by the source to a target, the series of raw values, and the sparse series of raw values.
Claims20
A method, comprising:
- at a source, performing a symbolic aggregation process on a series of raw data generated and/or collected by the source, to create a series of symbols;
- inputting, by the source, the series of raw data and the series of symbols to a lossy compression algorithm operating at the source;
- running, at the source, the lossy compression algorithm to obtain a series of raw values, and a sparse series of raw values;
- and
- transmitting, by the source to a target, the series of raw values, and the sparse series of raw values.
A non-transitory storage medium having stored therein instructions that are executable by one or more hardware processors to perform operations comprising:
- at a source, performing a symbolic aggregation process on a series of raw data generated and/or collected by the source, to create a series of symbols;
- inputting, by the source, the series of raw data and the series of symbols to a lossy compression algorithm operating at the source;
- running, at the source, the lossy compression algorithm to obtain a series of raw values, and a sparse series of raw values;
- and
- transmitting, by the source to a target, the series of raw values, and the sparse series of raw values.
