Abstract: Research work in the literature on imputation of mobility data for missing records of a subject's location trajectory has been specifically revolved around usage of historical data. Thus, performances drop when missing records or imputation mobility data for unknown subject with very little or no historical data has to be predicted. A method and system for training an ensemble classifier for imputation of mobility data of unknown subject based on cohort of the unknown subject is disclosed. The method and system disclosed herein exploits the knowledge that semantic trajectories of different individuals has considerable similarity when individuals belong to the same cohort. This concept is used by the method to predict the behavior of all the individuals in a cohort using ensemble classifier, also referred to as imputation model, trained on the semantic location data of a fraction of total individuals in the cohort with a certain accuracy.

Abstract: Systems and methods for a profile-based model selector are described. In some aspects, the system receives an input dataset and a corresponding input data profile and determines a similarity metric for the input data profile with respect to each of a plurality of data profiles. Based on the similarity metric for the input data profile being highest with respect to a first data profile, the system processes the input dataset using a first model associated with the first data profile. Based on determining that performance of the first model when applied to the input dataset is above a threshold, the system verifies a separating hyperplane is placed such that the first data profile and the input data profile are included in a first profile domain and a second data profile is included in a second profile domain.

Abstract: Sensors are regularly used to understand physical processing by computing systems and measuring physical quantities using principles of Physics which are then calibrated to yield the value and unit of interest. Some works have tried to generalize analytics across domains. However, they do not consider the problem of selecting sensors for a given application or having sensors as a service bouquet for application developer. Embodiments herein provide a method and system for recommending sensors for an application using elements of service-oriented-architecture and design (SOAD). Herein, the system contains a catalog of services which contain sensors and associated pipelines. These pipelines are used by the application developer along with calibration and fusion models through an Integrated Development and Prototyping Environment (IDPE).

Abstract: In some aspects, a computing system may identify a feature that can be used to distinguish between data that is more likely to be representative of the target population. A computing system may identify a feature in a dataset where a first value of the feature is associated with a higher likelihood that a corresponding sample is not a member of the target population. Due to the differences between samples that have the first value and samples that have the second value, the computing system may determine that samples with the first value are less likely to be members of the target population or samples with the second value are more likely to be members of the target population. The computing system may determine that a training dataset should be generated using samples that have the second value.

Abstract: Systems, methods, and apparatuses for automatically detecting and authorizing recurring transactions are described. Transaction data comprising transaction details for an incoming charge associated with a merchant may be received. Based on the merchant being included in a blocked merchants list, determining that authorization of incoming charges for preauthorized recurring transactions associated with the merchant are blocked. Based on a machine learning model and the transaction data, a probability that the incoming charge for the merchant is a preauthorized recurring transaction may be determined. The machine learning model may be configured to identify preauthorized recurring transactions based on the transaction data. Furthermore, based on the probability not exceeding a threshold probability, the authorization of the incoming charge may be prevented from being blocked.
