Abstract: Systems and methods of the present disclosure enable identifying labelling a source signal data signature using a computing system to test candidate chain oracle models by iteratively performing, for each particular number of neural network models in the range of the number of neural network models, a predetermined number of trials, where each trail includes: randomly selecting the particular number of neural network models; utilizing each neural network model of the particular number of neural network models to generate a respective predictive output based on the second input data; utilizing the LR model to generate a trial output based on the respective predictive output, and determining a model trial performance based on: the trial output, the second output data, and at least one machine learning performance metric. A chain oracle model from the candidate chain oracle models is determined based on the machine learning performance metric.

Abstract: Systems and methods of the present disclosure enable signal detection and/or recognition in audio recordings using one or more signal splitting techniques including a computing system configured therefor. The computing system may receive a signal data signature of time-varying data, the time-varying data having an event of interest and segment the signal data signature to isolate the event of interest by utilizing a first Hidden Markov model (HMM) configured to segment the signal data signature into at least one segment of the time-varying data by identifying state changes indicative of events of interest and where the at least one segment of the time-varying data has a first length. The computing system may use a second HMM configured to segment the at least one segment into a sub-segment of the time-varying data by identifying state changes within the at least one segment.

Abstract: Systems and methods provide a HybridOps model for the identification, capture, isolation, feature engineering and adjudication of source signal data signatures for inclusion in calibration quality standard reference signal data signature libraries that improve machine learning and validation, reduces model bias and reduces model drift. The HybridOps model may include an “unlocked” AI/ML (machine learning enabled) public facing deployment pipeline in parallel with a clone AI/ML deployed in an internal development environment using a ML-Ops pipeline and in parallel with a clone “locked” AI/ML (machine learning disabled) as a standard reference. The three deployed models enables monitoring and measuring model drift, context drift and product progression for improved verification and validation of model reliability.

Abstract: Systems and methods of the present disclosure enable signal data signature detection using a memory unit and processor, where the memory using stores a computer program or computer programs created by the physical interface on a temporary basis. The computer program, when executed, cause the processor to perform steps to receive a signal data signature recording from at least one data source, receive a dataset of labeled signal data signature recordings including signal data signature recording labels, identify, using at least one machine learning model, boundaries within the dataset of labeled signal data signature recordings, classify the signal data signature recording to produce an output label using a compendium of signal data signature classifiers based on the boundaries within the dataset of labeled signal data signature recordings, determine an output type of the signal data signature recording, and display the output label on a display media.

Abstract: Systems and methods of the present disclosure enable authentication and/or anomaly detection using machine learning-based modelling. Audio recordings that represent audio from a forced cough vocalizations are received from a user device. One or more audio filters extract forced cough vocalization recordings from the audio recordings and signal data signatures representative of the forced cough vocalization recordings are generated. Gaussian mixture models are produced for each unique combination of the signal data signatures, where each unique combination include a group of model baselines and a test match baseline. Each Gaussian mixture model is used to produce a match value for the associated test match baseline based on the associated model baselines, and a statistical score is determined for each match value. One or more baseline Gaussian mixture models are determined based on the statistical score and stored in a user profile.

Abstract: Systems and methods of the present disclosure enable automated detection of signal data signatures by receiving a first reward and a first state including a signal data signature recording having a first onset location and a first offset location. An action is performed to produce a second state with second onset and offset locations based on the first state, the first reward and a policy of a reinforcement learning agent. A discriminator machine learning model determines a match score representative of a similarity between the second state and a target distribution of a signal data signature type. A second reward is determined based on the match score and, based on the second reward exceeding a threshold, a modified signal data signature recording is produced with the signal data signature having a modified beginning and a modified end according to the second onset location and the second offset location, respectively.

Abstract: A money clip is disclosed with RF shielding characteristics to prevent skimming of stored magnetic and/or digital data in credit cards, quick pay devices, and other items that include magnetically stored personal data. The clip is formed of multiple layers of carbon cloth arranged to prevent transmission of radio frequencies in the range used to acquire the data. The layers are formed using a resin to bind the layers and the formation process resists the introduction of air into the device. The clip is strong enough to resiliently hold money, credit cards, and the like without losing its shape, and the shielding properties protect the contents for unauthorized data acquisition.
