Abstract: A security system detects objects using a machine learning model. At least one classifier head may be suffixed to the machine learning model. A classifier head is configured to determine a likelihood that the output of the machine learning model is accurate. Using the classifier head, the security system can determine whether to pass along the output of the machine learning model to a client device. The user can provide feedback on the accuracy of that output, which can then be used to re-train the classifier head. The security system may determine when to re-train the machine learning model based on an output of the classifier head. The security system may re-train the machine learning model using a subsampling of the original training dataset and an updated dataset that incorporates runtime sensor data and corresponding user feedback of the machine learning model's output.

Abstract: Embodiments may relate to dynamic processing pipelines that include multiple models communicatively coupled together (e.g., in series) to accomplish a task. Each model in a pipeline may be configured (e.g., trained or machine learned) for a specific task. For example, a first model in a pipeline may be trained to identify humans in images and a second model in the pipeline may be trained to detect furniture in images. The models may be stored on nodes of a network (e.g., an ad-hoc, peer-to-peer, and/or mesh network). The pipeline may be implemented by nodes of the pipeline applying received data to their corresponding models and then transmitting output data to the next node in the pipeline. Embodiments may relate to a graphical user interface (GUI) for viewing or filtering data of the pipeline according to one or more user-defined alert filters.

Abstract: A first time/temperature data set includes temperatures and time stamps recorded at time intervals during a first thermal cycling process and a time stamp for each time interval, and a second time/temperature data set includes temperatures and time stamps recorded at time intervals during a second thermal cycling process. Signal emissions at different signal detecting positions are sequentially measured at different time intervals to generate first and second time/signal emission data sets for receptacles subject to the first and second thermal cycling processes, respectively. Signal emissions of receptacles subject to the first thermal cycling process are synchronized with specific temperatures of the first thermal cycling process by comparing time stamps of the first time/signal emission data set for each receptacle with the time stamps of the first time/temperature data set that correspond with the specific temperature.
