System and technique for sliding window network coding-based packet generation
A method and apparatus decode packetized data in the presence of packet erasures using a finite sliding window technique. A decoder receives packets containing uncoded and coded symbols.

Mechanisms for continuous improvement of automated machine learning
Mechanisms are provided for optimizing an automated machine learning (AutoML) operation to configure parameters of a machine learning model. AutoML logic is configured based on an initial default value and initial range for sampling of a parameter of the machine learning (ML) model and an initial AutoML process is executed on the ML model based on a plurality of datasets comprising a plurality of domains of data elements, utilizing the initially configured AutoML logic. For each domain, a cross-dataset default value and cross-dataset value range are derived from results of the execution of the initial AutoML process. For each domain, an entry is stored in a data structure, the entry storing the derived cross-dataset default value and cross-dataset value range for the domain. The AutoML logic performs a subsequent AutoML process on a new dataset based on one or more entries of the data structure. |

Performance score determiner for binary signal classifiers
There are disclosed devices, system and methods for determining a performance score for a trained binary signal classifier (classifier) by determining test output predictions for test input data entries that are input into the classifier. The test outputs are then compared to known outputs of each of the input data entries to determine whether each test output is a true negative (TN), true positive (TP), false negative (FN) or false positive (FP). A number of correct test outputs (R) is defined as a number of the true negative outputs (TN) plus a number of the true positive outputs (TP). A number of incorrect test outputs (W) is defined as a number of the false negative outputs (FN) plus a number of the false positive outputs (FP). The performance score is then calculated using a mathematical expression that decreases as W increases, decreases as TN decreases and decreases as TP decreases. |

In the learning model, the network structure has a plurality of functions trained so as to evaluate influence from each label in the label set depending on a relationship between the target positional value and a representative positional value associated with the label in the label set. A target outcome is estimated for the target positional value from the input set using the learning model. |

Integrated quantum computer incorporating quantum core and associated classical control circuitry
A novel and useful fully integrated quantum computer containing both quantum core circuitry and associated classical electronic control circuits on the same monolithic die. The integrated quantum computer avoids ESD loading on the quantum structures and minimizes the need for long interconnects with resultant large parasitic inductances and capacitances. Such parasitics reduce the maximum operating frequency of the realized quantum core structures. A cryostat unit functions to provide several temperatures to the quantum computer including a temperature to cool the quantum core to approximately 4° K and the interface SoC to 77° K. Alternatively, the interface circuitry is also integrated with the main QPU on the same die. A programmable pattern generator executes sequences of instructions that control the quantum core. In accordance with the sequences, a pulse generator functions to generate the control signals that are input to the quantum core to perform quantum operations. |
