Abstract
Systems and methods for executing queries on a bitmap index are disclosed. The system may receive a first data stream from a database and generate a bitmap index based on the first data stream. The system may receive an input selection of one or more data conditions from a user device and generate a Boolean expression based on the input selection. The system may query the bitmap index using the Boolean expression and generate a bitmap vector. The system may output a first data subset represented by the generated bitmap vector to a graphical user interface. The bitmap index may include probabilistic entries, and the system may validate the probabilistic entries by receiving a second data stream, identifying one or more entries correlated to the probabilistic entries, determining a divergence between the identified entries and the probabilistic entries, and updating parameters of a classifier model associated with the probabilistic entries.
