    摘要： Methods and systems for federated learning using feature normalization are disclosed. A client implements a local model including at least: a feature extraction subnetwork to extract a feature vector from input data, a normalization layer to normalize the feature vector, and a final layer to generate a prediction output from the normalized feature vector. The local model is initialized using a set of global parameters received from a central server. The local model is updated using data sampled from a local dataset. Information about a state of the updated local model is transmitted to the central server.

    摘要： A packaging device incorporating a breathable peel/reseal film and enabling a preservation process for allowing for the distribution, storage and multiple servings of a food product, particularly perishable food product(s), and initiating and controlling the transmission rates, respiration rates or deterioration of the perishable food product(s) and thereby, maintaining good internal and external food quality and normal development of flavor and aroma characteristics. The packaging device includes a plurality of atmospheric control attributes that modulates or controls the atmosphere within the packaging device as the food product(s) respire in order to promote the extended shelf-life of the food product and the maintenance of the quality and desirable marketable characteristics of the food product. The atmospheric control attributes can include perforations that may be positioned in breathable peel/reseal film portion of the package to allow the product respiration for multiple servings without substantially altering the shelf life extension properties of the packaging device.
