Embodiment Construction

[0028] Attached below figure 1 -6 and examples further illustrate the present invention:

[0029] The present invention provides a data preprocessing method based on blockchain smart contracts and machine learning, the system flow chart is as follows image 3 As shown, the IOT data collection system collects the original data, organizes the data into a standardized data set, and trains the data set through machine learning. The data processing results are obtained through the model, and finally the results are displayed in the background of the blockchain.

[0030] Specifically include the following steps:

[0031] Step 1: Collect data through sensor upload, smart device collection, etc. and store it in the local node. Standardize the collected data to form training data for training and test data for testing. The data at this time is Standardized data such as Figure 4 shown, and not stored in the blockchain;

[0032] Step 2: write machine learning algorithm on python, t...

Abstract

The invention discloses a data preprocessing method based on a block chain intelligent contract and machine learning. Data preprocessing on nodes is completed through cooperation of a block chain technology and a machine learning technology. The method specifically comprises the steps of collecting Internet of Things data, and standardizing the Internet of Things data after storing the Internet ofThings data to local nodes; C; creating a machine learning algorithm file on the local node, wherein the machine learning algorithm file is used for preprocessing the Internet of Things data; S; storing the data into a block chain; T; training a learning algorithm by using the linked data to obtain a model coefficient, and storing the model coefficient in a local node; Firstly, a machine learningalgorithm expression is written into an intelligent contract, and then an obtained model coefficient is stored into a block chain by calling the intelligent contract; P; processing the to-be-processed data by using the linked model; A; and storing the processed data into a block chain. According to the method, a machine learning algorithm is added into an intelligent contract of a block chain, and the data mining capability of the block chain is improved by utilizing machine learning.

Description

technical field [0001] The invention belongs to the field of block chain technology, the field of data analysis technology, and the field of data security. Background technique [0002] In recent years, the strong rise of artificial intelligence has made people deeply appreciate the huge potential of artificial intelligence technology. Data is the carrier, intelligence is the goal, and machine learning is the technology and method from data to intelligence. Data itself is unconscious, it cannot automatically present useful information. In layman's terms, machine learning is to mine valuable information from data. [0003] Since the Internet kidnapping virus broke out in 2016, "Bitcoin" has gradually entered the public's field of vision. At that time, most people's understanding of Bitcoin was limited to a virtual transaction currency. In the two years since then, the ratio of "bitcoin" to the dollar has been increasing day by day. At the same time, it is the underlying t...
