  • Publication number: 20230410612
    Abstract: A system and method for conducting a game between at least one live player and at least one computer-controlled player includes executing a training program between at least two agents to generate probability weights correlating actions or meta-actions representing a set or sequenced set of actions with a probability that the action or meta-action will produce a game outcome meeting a specified criterion or specified criteria. A game is conducted in which at least one live player plays against at least one computer-controlled player in which the computer-controlled player selects actions at one or more of the decision nodes in the game based, at least in part, on the probability weights.

  • Patent number: 11741794
    Abstract: A system for conducting a game between at least one computer-controlled player and at least one live player includes a plurality of neural nets. Each of the plurality of neural nets are associated with a different game state of a game. A plurality of instructions are stored in a data storage and executable by a data processor. The data processor determines a current state vector for the game responsive to game states of the game. The processor selects a neural net from the plurality of neural nets responsive to the current state vector. The data processor feeds the current state vector to the selected neural net and the selected neural net generates an output vector from the selected neural net responsive to the current state vector. The output vector provides a plurality of candidate meta-actions. The plurality of candidate meta-actions associated with the output vector are weighted responsive to a probability associated therewith.

  • Publication number: 20230159991
    Abstract: This disclosure provides, inter alia, a probe system probe system for analyzing a nucleic acid sample. In some embodiments, the probe system may comprise: a set of identifier oligonucleotides of sequence B, a set of splint oligonucleotides of formula X?-A?-B?-Z?, wherein sequence A? is complementary to a genomic fragment and sequence B? is complementary to at least one member of the set of identifier oligonucleotides, and one or more probe sequences comprising X and Z. Each splint oligonucleotide is capable of hybridizing to the probe sequences, a member of the set of identifier oligonucleotides and a genomic fragment, thereby producing a ligatable complex of formula X-A-B-Z. The probe system can be used to identify a chromosome aneuploidy in cell free DNA, for example.

  • Patent number: 10876169
    Abstract: A method of estimating the amount of a methylated locus is provided. In certain embodiments the method comprises: digesting a nucleic acid sample that contains both unmethylated and methylated copies of a genomic locus with an MspJI family member to produce a population of fragments that are in the range of 20-40 nucleotides in length, ligating adaptor sequence A and adaptor sequence B to the respective ends of a target fragment of sequence X, and quantifying the amount of ligation products of formula A-X-B. A kit for performing the method is also provided.

  • Publication number: 20200140922
    Abstract: Described herein is a new approach in which a nucleic acid species of interest (e.g. a chromosome) containing multiple unique target sequences is detected using multiple specific probes that are amplified by rolling circle amplification and detected. Multiple probes are used to provide a detectable signal, where the magnitude of the signal is proportional to the number of probes recognising their target sequences. Individual signals from the plurality of probes are converted into a single cumulative detectable signal, amplifying the individual signals through the multiplex probing. Ten or more probes produce a signal amplification of ten-fold or more. The generated signals depend on correctly reacted probes upon target recognition, using sequence specific hybridisation and enzymatic catalysis to generate specific products from which the signal is obtained.
