The blockchain is hot and artificial, whether it is artificial or not.
The update speed of technology is extremely fast. From the beginning of VR and AR technology to the blockchain technology of artificial intelligence technology and finally to the present, some people say that after the blockchain fires, artificial intelligence begins to slowly cool down. There is no connection between blockchain and AI, and whether they go together.
At the beginning of 2018, the blockchain became a topic of the whole nation. Is artificial intelligence already cool?
Is there a correlation between the seemingly irrelevant blockchain and AI? What is the motivation for combining blockchain and AI? What are the APPs that combine the blockchain and AI technologies?
Siraj Raval compares the relationship between AI and blockchain to yin and yang, with a synergy. The synergy between the two technologies is because the two are based on very different technical foundations, but they each complement each other.
AI is based on probability, it keeps changing, we don't know what the outcome is, these AI algorithms will constantly update their own weights and learning strategies, updating estimates based on training sets and real situations.
The blockchain pursues the other side, that is, certainty, which means that the results are deterministic, and the results are real and will never change. Corresponding algorithms and encryption methods are used to record the truth. The blockchain pays more attention to verifiability and persistence as well as greater certainty and controllability.
The video lists two practical examples of AI+Blockchain:
The first is the decentralized data analysis market platform OpenMind.
Imagine that AI ScienTIst now wants to train a deep neural network model, and needs to call some data to train the model. If a third-party centralized platform or program is used, your information is likely to be stolen, or AI ScienTIst is well designed. The model is for you, but you have stolen the model. As long as there is a third party involved, the third party can steal your data and steal the AI ​​ScienTIst model.
How to circumvent this information disclosure or stealing? The solution for OpenMind is: AI ScienTIst buys your data, after training your model with your data, just take the model and not touch your data. This process AI Scientist and you, who do not have to trust anyone. The method used here is to use AI+Blockchain.
The other is the decentralized AI hedge fund NumberAI.
NumberAI can provide free data for all stock markets, and Data Scientist can also use this data, and then use the acquired data to train the model and submit the prediction results to NumberAI.
After a time test, you know which models are the most accurate. The person with the most accurate predictions can not only recover the cost, but also get rewards. This reward system is for everyone and is designed to improve forecasting accuracy. However, if you don't predict well enough, your money will be lost.
These predictions are supported by tokens (NumberAI's internal token NMR), which is built on the Ethereum blockchain and will get the models submitted by all data scientists, and then NumberAI will integrate these models. Into a meta model, so this metamodel is formed.
The internal tokens in this role take on a number of functions. You can use this internal token like a currency, or you can store a part of it, and use it as a stock in a blockchain network so that the value of the token is Being able to add value over time, the profit of the entire blockchain network is also growing. This is a way to share profits. If my NumberAI version doesn't have an internal token, then Data Scientist can't share the profit.
The role of Bushing Cover : is the use of non-conductive material will be charged with isolation or wrapped up the characteristics of a safety measure to prevent electric shock. Good insulation to ensure the safe operation of electrical equipment and lines.
Applications:
1. Busbar Insulation Cover can Effectively eliminate short circuit accidents caused by small animals such as birds and animals or foreign body lap.
2. Prevent electrical accidents caused by condensation flash branding, dirty flash branding and icicle sticking to snow.
3. Bushing Covers can prevent acid rain, salt spray and harmful chemical gases from corrosion of transformer inlet and outlet lines.
4. Avoid casualties caused by pedestrians touching exposed electrical contacts by mistake.
5. The protective cover and metering device can be fully closed operation to prevent illegal elements stealing electricity.
6. Buckle structure, simple installation, reusable.
