Abstract: A new linear machine learning method based on DNA hybridization reaction technology, includes a machine learning training part, an algorithm part, and a testing part. This machine learning method has the ability to learn linear functions. Unlike silicon circuits, the learning algorithm is implemented through the synchronization of DNA hybridization reactions. Therefore, the calculation mode of this machine learning method is a parallel computing model, and the weights of this machine learning are obtained through training without the involvement of electronic computers. Through the method, it is possible to learn multivariable linear functions without any limitation on the number of input terms. Due to the non-negative DNA concentration, the method used a dual track model for negative data processing operations.

The technology determines votes from the plurality of IoT devices, where the votes indicate whether the model update will be deployed. The technology deploys the model update to the plurality of IoT devices based on the votes.

Abstract: The present invention discloses a polypeptide and application thereof. By modifying oxyntomodulin (OXM), hybridizing OXM with a peptide sequence of Exenatide, including enabling the polypeptide to be resistant to DPP-4 enzyme degradation through amino acid modification, and conjugating fatty acid chains at the same time, an OXM hybrid peptide having longer pharmacologic action time and better weight losing effects is obtained. Synthesis of a target polypeptide is fast realized by an orthogonal protection strategy solid-phase synthesis method, and a crude product is purified and freeze-dried to obtain the OXM hybrid peptide.
