  • Publication number: 20230420075
    Abstract: This disclosure describes methods, non-transitory computer readable media, and systems that can determine allele likelihoods of a genomic region exhibiting certain haplotype alleles using one or both of consolidated computations and data exchanges across specialized hardware. For instance, the disclosed systems can determine an intermediate allele likelihood of a genomic region comprising a haplotype allele by running a single-pass-concurrent-multiplication operation. In some cases, the disclosed systems determine and store subsets of intermediate allele likelihoods corresponding to marker-variant groups and extemporaneously generate sets of intermediate allele likelihoods for a set of marker variants by using the intermediate-allele-likelihood subsets as hot-start points.

  • Publication number: 20220301657
    Abstract: A system for base calling includes memory storing a topology of a neural network, a plurality of weights sets, and sensor data for a series of sensing cycles. Sequencing events span temporal progression of the base calling operation through subseries of sensing cycles, and spatial progression of the base calling operation through locations on a biosensor. A configurable processor is configured to load the topology on the configurable processor, select a weight set in dependence upon a subject subseries of sensing cycles and/or a subject location on the biosensor, load subject sensor data for the subject subseries of sensing cycles and the subject location on the processing elements, configure the topology using the selected weight set, and cause the neural network to process the subject sensor data to produce base call classification data for the subject subseries and the subject location.

  • Publication number: 20210265015
    Abstract: A system for analysis of base call sensor output has memory accessible by the runtime program storing tile data including sensor data for a tile from sensing cycles of a base calling operation. A neural network processor having access to the memory is configured to execute runs of a neural network using trained parameters to produce classification data for sensing cycles. A run of the neural network operates on a sequence of N arrays of tile data from respective sensing cycles of N sensing cycles, including a subject cycle, to produce the classification data for the subject cycle. Data flow logic moves tile data and the trained parameters from the memory to the neural network processor for runs of the neural network using input units including data for spatially aligned patches of the N arrays from respective sensing cycles of N sensing cycles.

  • Publication number: 20200216064
    Abstract: Among other things, systems and methods for classifying perceived objects based on activity are disclosed. The systems and methods can include means for receiving sensor information corresponding to at least one object and determining an activity prediction for the at least one object in accordance with the sensor information. The system and methods can include means for classifying the object in accordance with the activity prediction. A controller circuit can operate control functions of a vehicle at least partially based on the classification of the at least one object.

  • Patent number: 10558936
    Abstract: Systems and methods are described herein for dynamically generating and updating a patrol schedule for a shift based on historic demand event data, and a predicted-demand model based on the historic demand event data. The systems and methods also receive information associated with patrol officers assigned to a shift and constraints on the officers' availability, and generate a patrol schedule comprising patrol assignments for the assigned patrol officers optimized based on at least one policing objective. The patrol schedule may be dynamically updated based on changing information and provided to the patrol officer via mobile device or display in the patrol officer's vehicle.

  • Patent number: 10218465
    Abstract: A system and method includes employing a cyclical redundancy check (CRC) code to information being transmitted on the channel, the CRC code including appending a single CRC code bit to the information, the single CRC code bit having a value of 0. The method further includes adding an error correcting code with a value of 0 to the information and to a plurality of error correcting code parity bits provided by the error correcting code. The method further includes transmitting, by the communication device, the information on the channel without the single CRC code bit, the additional information bit, and the error correcting code parity bits for being decoded and set by a receiver.
