  • Patent number: 12223432
    Abstract: A method and system of training an interpretable deep learning model includes receiving an input set of data, which may be complex. The input set of data is provided to deep learning model for feature extraction. In an exemplary embodiment, the deep learning model generates a disentangled latent space of features from the feature extraction. The features may comprise semantically meaningful data which is then provided to a low-complexity learning model. The low-complexity learning model generates output based on a specified task (for example, classification or regression). Being a low-complexity learning model provides confidence that the data output from the deep learning model is inherently interpretable.

  • Patent number: 11836621
    Abstract: An output time-series of a cell of a neural network is captured. A subset of a set of data points of the output time-series is consolidated into a singular data point. The singular data point is fitted in a data representation to form a quantified aggregated data point. The quantified aggregated data point is included in an intermediate time-series. Using the intermediate time-series as an input at an intermediate layer of the neural network, an anonymized output time-series is produced from the neural network.

  • Publication number: 20230281518
    Abstract: Second machine learning models trained using respective second data sets can be received. The second machine learning models can be run using a first data set used in training a first machine learning model, where the second machine learning models produce respective outputs. Scores associated with the second machine learning models can be determined by comparing the respective outputs with ground truth associated with the first data set. Based on the scores associated with the second machine learning models, whether the first data set is to be discarded or kept can be determined for training the first machine learning model.

  • Publication number: 20230186072
    Abstract: Providing an explanation for model outcome can include receiving input data, and passing the input data through an attention-based neural network, where the attention-based neural network learns attention weights associated with contextual embeddings corresponding to tokens of the input data and predicts an outcome corresponding to the input data. Based on an attention weight associated with a contextual embedding corresponding to a token of the input data, a signed relevance score can be determined to associate with the token for quantifying the token's relevance to the outcome. Based on the signed relevance score, an explanation of the token's contribution toward or against the outcome can be provided. The signed relevance score can be computed as a gradient of loss with respect to the attention weight.

  • Publication number: 20230177323
    Abstract: A first instance of data and a second instance of data can be received, which have been classified differently. The first instance can be input to a first neural network, the first neural network generating a first encoding associated with the first instance. The second instance can be input to a second neural network the second neural network generating a second encoding associated with the second instance. The first neural network and the second neural network form neural network architecture trained to learn similarities in given pair of input objects. Based on the first encoding and the second encoding, a difference can be identified in features of the first instance and the second instance, which contributed to the first instance and the second instance being classified differently.

  • Patent number: 11494637
    Abstract: Neural network protection mechanisms are provided. The neural network protection engine receives a pre-trained neural network computer model and forward propagates a dataset through layers of the pre-trained neural network computer model to compute, for each layer of the pre-trained neural network computer model, inputs and outputs of the layer. For at least one layer of the pre-trained neural network computer model, a differentially private distillation operation is performed on the inputs and outputs of the at least one layer to generate modified operational parameters of the at least one layer. The modified operational parameters of the at least one layer obfuscate aspects of an original training dataset used to train the pre-trained neural network computer model, present in original operational parameters of the at least one layer. The neural network protection engine generates a privatized trained neural network model based on the modified operational parameters.

  • Patent number: 11444702
    Abstract: Systems and methods for identifying a device are described. In an example, a processor can receive a first signal having a first waveform encoding data. The processor can extract the data from the first signal. The processor can determine a transformation being used to encode the data in the first waveform. The processor can generate a second signal using the determined transformation to encode the data in a second waveform. The processor can determine a difference between the first waveform and the second waveform. The processor can identify a device as a candidate device that sent the first signal, based on the determined difference.
