  • Patent number: 11676006
    Abstract: According to some embodiments, a universal modeling system may include a plurality of domain expert models to each receive raw input data (e.g., a stream of audio frames containing speech utterances) and provide a domain expert output based on the raw input data. A neural mixture component may then generate a weight corresponding to each domain expert model based on information created by the plurality of domain expert models (e.g., hidden features and/or row convolution). The weights might be associated with, for example, constrained scalar numbers, unconstrained scaler numbers, vectors, matrices, etc. An output layer may provide a universal modeling system output (e.g., an automatic speech recognition result) based on each domain expert output after being multiplied by the corresponding weight for that domain expert model.

  • Publication number: 20220307006
    Abstract: Methods and compositions are provided for the improvement of homology-directed repair of a double strand break in a plant cell, using concatemers of heterologous polynucleotides that are flanked by sequences capable of sequence hybridization with a guide RNA. In some aspects, the double strand break is created by an RNA-guided Cas endonuclease. The homology-directed repair of the double-strand break may include incorporation of a heterologous polynucleotide, for example a gene encoding a trait of agronomic importance. The homology-directed repair of the double-strand break may occur as a result of template-directed repair using a heterologous polynucleotide as a repair template.
