Abstract
An artefact is received. Features from such artefact are extracted and then populated in a vector. Subsequently, one of a plurality of available dimension reduction techniques are selected. Using the selected dimension reduction technique, the features in the vector are reduced. The vector is then input into a classification model and the score can be provided to a consuming application or process. Related apparatus, systems, techniques and articles are also described.
Claims21
A computer-implemented method comprising:
- receiving an artefact;
- extracting features from the artefact and populating a vector;
- selecting one of a plurality of available dimension reduction techniques;
- reducing the features in the vector using the selected dimension reduction technique;
- inputting the vector into a classification model to generate a score;
- and
- providing the score to a consuming application or process.
