  • Publication number: 20250077313
    Abstract: A processor-implemented method for generating a default adapter for context switching includes analyzing a first neural network model and one or more adapters. The first neural network model is pre-trained and each of the adapters is configured with an architecture and parameters for performing a different downstream task of a set of downstream tasks. A default adapter is defined based on a capacity of the one or more adapters. The default adapter is applied to one or more layers of the first neural network model during a context switch to a replace one of the adapters for a different task. A graph corresponding to the first neural network model is unchanged.

  • Publication number: 20250054491
    Abstract: Systems and methods are provided for smart audio segmentation using look-ahead based acousto-linguistic features. For example, systems and methods are provided for obtaining audio, processing the audio, identifying a potential segmentation boundary within the audio, and determining whether to generate a segment break at the potential segmentation boundary. One or more look-ahead words occurring after the potential segmentation boundary are identified, wherein an acoustic segmentation score and a language segmentation score associated with the potential segmentation boundary and the one or more look-ahead words are generated. Systems then either refrain from generating a segment break at the potential segmentation boundary or generate the segment break at the potential segmentation boundary based on the acoustic and/or language segmentation score at least meeting or exceeding a segmentation score threshold.

  • Publication number: 20250053738
    Abstract: Aspects of this disclosure are directed to techniques that enable efficient automated text-to-speech pronunciation editing for long form text documents. A computing device comprising a memory and a processor may be configured to perform the techniques. The memory may store a text document. The processor may process words in the text document to identify first candidate words that are predicted to be mispronounced during automated text-to-speech processing of the text document. The processor may next filter the first candidate words to remove one or more candidate words of the first candidate words and obtain second candidate words that have fewer candidate words than the first candidate words. The processor may then annotate the text document to obtain an annotated text document that identifies the second candidate words, and output at least a portion of the annotated text document that identifies at least one candidate word of the second candidate words.

  • Publication number: 20250029682
    Abstract: In comparison to conventional sequencing pileup algorithms, the process described herein generates sequencing pileups that contains additional information not typically reported by conventional algorithms while also consuming fewer computational resources (e.g., time, processing power, and memory). First, each of a FASTA reference genome and BAM sequence read files are converted to an internal representation. This enables the rapid iteration across nucleotide bases of the sequence reads to determine support characteristics that summarize information of nucleic acid molecules corresponding to positions across the reference genome. Next, the support characteristics of positions across the reference genome are stored through a memory allocation process that utilizes a first and a second temporary storage. This enables the convenient freeing of one temporary storage while the other temporary storage is being used.

  • Publication number: 20240309461
    Abstract: Methods and systems for sample contamination detection are disclosed. In particular, sample barcodes are utilized, wherein each sample barcode is assigned to a sample and ligated to fragments from the sample. The sample barcodes are used in conjunction with indices from sequencing libraries to accurately assign sequence reads to samples during multiplex sequencing. Molecule identifiers may also be utilized to aid in de-duping of sequence reads to precisely identify original NA fragments from a sample. Accordingly, in one or more embodiments, a sequencing method includes isolating DNA fragments in a sample, ligating the DNA fragments with unique molecule identifiers (UMIs), performing an amplification process resulting in amplicons, ligating a sample barcode onto the amplicons, and performing amplicon sequencing. The analytics system looks to whether indices are matched and whether a sample barcode matches to the pair of indices when identifying single-index or double-index hopping events.

  • Patent number: 11974765
    Abstract: A mouth insert for treating nosebleeds includes a main body and a bite tab. The bite tab removably engages the main body and is configured to move up and/or down vertically in order to adjust the height of the device.

  • Publication number: 20240055073
    Abstract: Methods and systems for detecting contaminated fragments in a biological sample for cancer classification are disclosed. The system identifies CpG-SNP contamination markers. The CpG-SNP contamination markers include at least one SNP that affects a CpG site. The CpG-SNP contamination markers may include additive CpG-SNP sites and/or subtractive CpG-SNP sites. Additive CpG-SNP sites include an SNP that creates a new CpG site. Subtractive CpG-SNP sites include an SNP that removes a preexisting CpG site. Hybrid sites may include additional sites. A multiple CpG-SNP contamination marker comprises two or more CpG-SNP sites. A CpG-SNP & indel contamination marker comprises at least one CpG-SNP site and an indel site. For a given sample, the system identifies contamination markers for which the sample is homozygous. The system determines fragments having a haplotype that is different from the homozygous haplotype of the sample to be contamination fragments.

  • Publication number: 20210285042
    Abstract: An allelic position variant calling method using a prior genotype probability at the allelic position is provided. A strand specific base count set in forward and reverse directions for the allelic position is obtained, using strand orientation and identity of a respective base at the allelic position in each respective nucleic acid fragment sequence that maps to the allelic position, where bases at the allelic position whose identity can be affected by conversion of cytosine to uracil do not contribute to the strand specific base count set. Respective forward and reverse strand conditional probabilities are computed for each candidate genotype for the allelic position using the strand specific base count set and sequencing error estimate. Likelihoods are computed using a combination of these conditional probabilities and the prior genotype probability. From this, a determination is made as to whether the likelihoods support a variant call at the allelic position.

  • Publication number: 20210065847
    Abstract: Systems and methods for determining consensus base calls in nucleic acid sequencing are provided. A sequencing dataset is obtained corresponding to a plurality of base reads for a first base position within a plurality of base positions of a target nucleic acid molecule. The sequencing dataset includes at least two features, for each base read of the plurality of base reads. The at least two features are selected from among the features: a nucleotide base, a read quality score, a strand identifier, a trinucleotide context of the base read, and a confidence score associated with the trinucleotide context. The sequencing dataset is transformed into a feature tensor representing a distribution of the plurality of features in the sequencing dataset. The feature tensor is assessed with a classifier to determine a consensus base call for the first base position. The consensus base call comprises a predicted nucleotide base.
