  • Publication number: 20240303331
    Abstract: Provided are methods, systems, and non-transitory computer-readable media for generating a feature vector for malware, including storing, in memory of a computing device, program code for a trained neural network that produces embedded representations for antivirus scan data; executing, by a processor of the computing device, the program code for the trained neural network to perform the operations of: (a) receiving an antivirus scan report (AVSR) for a malware file; (b) normalizing each label in the AVSR by separating the label into a sequence of tokens including a set of token strings; (c) embedding a first token and plural second tokens to generate an input sequence for the malware file; (d) inputting the input sequence into a neural model for producing antivirus scan data; and (e) outputting the antivirus scan data produced by the neural model as one or more feature vectors.

  • Patent number: 11977632
    Abstract: Disclosed are methods and apparatuses for classifier evaluation. The evaluation involves constructing a ground truth refinement having a degree of error within specified bounds from a malware reference dataset as an approximate ground truth refinement. The evaluation further involves using the approximate ground truth refinement to determine at least one of: a lower bound on precision or an upper bound on recall and accuracy. The evaluation further involves evaluating a classifier by evaluating at least one of a classification method or clustering method by examining changes to the upper bound and/or the lower bound produced by the approximate ground truth refinement.

  • Patent number: 4227887
    Abstract: A three phase process for determining total organic halides in water. The first phase is a sorptive process including passing a liquid through a packed bed of sorptive material thereby removing quantitatively, purgeable and non-purgeable, organic halides and thereafter passing an inorganic halide displacement wash solution through the bed to displace inorganic halides. The second and third phases are a combination combustion and titration whereby organic bromides and other organic halides entering the combustion phase are quantitatively titrated coulometrically.
