Abstract: A machine learning model can be optimized for deployment on a device based on hardware specifications of the device. An existing model is acquired and pruned to reduce hardware resource consumption of the model. The pruned model is then trained based on training data. The pruned model is also trained based on a collection of “teacher” models. Performance of the trained model is then evaluated and compared to performance requirements, which can be based on the hardware specifications of a device.

Abstract: One or both of epilepsy seizure detection and prediction at least by performing the following: running multiple input signals from sensors for epilepsy seizure detection through multiple classification models, and applying weights to outputs of each of the classification models to create a final classification output. The weights are adjusted to tune relative output contribution from each classifier model in order that accuracy of the final classification output is improved, while power consumption of all the classification models is reduced. One or both of epilepsy seizure detection and prediction are performed with the adjusted weights. Another method uses streams from sensors for epilepsy seizure detection to train and create the classification models, with fixed weights once trained. Information defining the classification models with fixed weights is communicated to wearable computer platforms for epilepsy seizure detection and prediction.

Abstract: Disclosed are the cation polymers capable of removing their positive charges in oxidative conditions, preparation methods, and applications as gene delivery carriers. The oxidation-responsive unit is the p-(boronic acid or ester)benzylammonium, which upon oxidation eliminates p-hydroxymethlphenol and thus converts in a tertiary amine. Compared with the prior art, different from a common quaternary amination carrier, the synthesized charge reversal type gene delivery carrier for oxidative response of the present invention has a large quantity of positive charges and can well coat a DNA, but the positive charges can be removed under the condition of intracellular oxidation when the charge reversal type gene delivery carrier enters a cell, a charge reverse is triggered, the positive charges turn to negative charges, and the DNA is quickly released for transfection. The carrier is efficient, low in toxicity, and good in application prospect.
