Scan optimization of column oriented storage
SCAN operations for databases where scan time is dependent on a payload size consume too much memory space and computing time as payload sizes increase. A database table is configured to include an additional index mapping column that stores bitmaps related to the corresponding row of the table. Each bit in the bitmap corresponds to a column and indicates whether that column stores a value. Inclusion of an index column in a table decouples the time it takes to perform the SCAN operation on a column from the payload size of data stored in the column. The bitmaps stored in the index column are relatively small and uniform in size, so the SCAN operation on such a database requires only for the bitmap values of the applicable rows to be obtained from the index column and inspected. |

Expression pushdown optimization for querying in federated database system
A system for query optimization by a federation engine is provided. When a data source supports a target feature of an expression of a query in the common query language, the system executes a converter for the data source to convert the target feature to the corresponding feature of the data source query language. The system then submits to the data source a query with the expression with the converted target feature so that the expression is evaluated at the data source and receives query results. When a data source does not support the target feature of the expression, the system submits to the data source a query without the expression and evaluates the expression on the query results returned by the data source. The system then combines the query results based on the evaluation of the expression as the query results of the query. |

Adjustable precision for multi-stage compute processes
Disclosed techniques provide for dynamically changing precision of a multi-stage compute process. For example, changing neural network (NN) parameters on a per-layer basis depending on properties of incoming data streams and per-layer performance of an NN among other considerations. NNs include multiple layers that may each be calculated with a different degree of accuracy and therefore, compute resource overhead (e.g., memory, processor resources, etc.). NNs are usually trained with 32-bit or 16-bit floating-point numbers. Once trained, an NN may be deployed in production. One approach to reduce compute overhead is to reduce parameter precision of NNs to 16 or 8 for deployment. The conversion to an acceptable lower precision is usually determined manually before deployment and precision levels are fixed while deployed. Disclosed techniques and implementations address automatic rather than manual determination or precision levels for different stages and dynamically adjusting precision for each stage at run-time. |

Frequency-modulated continuous-wave (FMCW) radar-based detection of living objects
The techniques of this disclosure enable frequency-modulated continuous-wave radar-based detection of living objects. Instead of generating a chirp pattern with each chirp separated by an idle period, a radar generates a chirp pattern with multiple chirps separated by an idle period. From applying a Fourier transform to receiver signals for each frame, the radar determines an amplitude as a function of range for each frame. The radar computes the standard deviation between the amplitudes of two frames and then, for each additional frame, the radar incrementally updates the standard deviation to be inclusive of the amplitude contribution of the additional frame. That is, rather than recalculate the standard deviation for each new frame, the radar increments the standard deviation by a fraction of the amplitude for the new frame, which is proportionate to the total quantity of frames generated thus far. In response to the standard deviation satisfying a noise threshold, the radar outputs an indication of a living object. |
