Decentralized recommendation mechanism

2. Decentralization is a phenomenon or structure, which can only appear in a system with many users or nodes, and each user can connect and influence other nodes. Generally speaking, everyone is the center, and everyone can connect and influence other nodes. This flat, open-source and equal phenomenon or structure is called "decentralization"< Br > at the same time, "decentralization" is one of the typical features of blockchain, which uses distributed storage and computing power. The rights and obligations of the whole network nodes are the same, and the data in the system is jointly maintained by the whole network nodes, so that the blockchain no longer relies on the central processing node to realize the distributed storage, recording and updating of data. Each blockchain follows a unified rule, which is based on a cryptographic algorithm rather than a credit certificate, and the data update process needs to be approved by the user, so that the blockchain does not need the endorsement of intermediaries and trust institutions< The characteristics of br> de centralization:
centralization is first reflected in diversification. In the Internet world, there are no more than several portals has the final say. Various websites have begun to voice their own voice, express different choices and different hobbies, and these websites are distributed in every corner of the Internet world. Br > decentralisation is followed by the centralization of people, and decentralisation of content has become a trend, and people have become the key force to determine the survival of websites. It's a great change to build a website with indivials who lack interaction to gather talents and contribute their wisdom in the form of a circle. That is user-oriented, humanized< < br > decentralized content: < br > decentralization is the form of social relationship and content generation formed in the development of the Internet, which is a new network content proction process relative to "centralization"< Br > compared with the early Internet (Web1.0) era, today's Web (Web2.0) content is no longer proced by professional websites or specific groups of people, but is created by all Internet users with equal rights. Anyone can express their views or create original content on the Internet to proce information together< Br > with the diversification of network service forms, the decentralized network model is becoming clearer and more possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together< After that, with the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web2.0 became more and more obvious. For example, the birth of services more suitable for ordinary Internet users, such as twitter and Facebook, made it easier and more diversified to proce or contribute content to the Internet, thus enhancing the enthusiasm of Internet users to participate in the contribution and recing the threshold of procing content. Eventually, every netizen becomes a tiny and independent information provider, making the Internet more flat and content proction more diversified.

3. One of the characteristics of media theory is the wide ambiguity of various views. On the relationship between media and society, one of the focuses of the debate is the theoretical debate between "media centric" and "social centric", First, the view of "media center" lays particular stress on the field of media activities. It holds that the mass media, influenced by the irresistible driving force of the development of communication technology, has formed an independent force beyond the law of social movement. Mass communication has its own mode of operation and logic, highlighting the autonomy and influence of the media“ The view of "social center" regards the mass media as the reflection of political and economic forces, and holds that the media, just like its original intention, is only the carrier of information transmission. Therefore, the media theory is only a special application of the larger social theory. Second, the "media center" theory holds that the mass media has the ability to "acculturate" and "cultivate" the society, And regard the mass media as the main instigator of social change“ The theory of "social center" holds that media is always under the influence of social forces. It belongs to society and bears special responsibility for society. It is not difficult to see that the differences between theories are irreconcilable e to different footholds

4. What is the algorithm for tiktok? TikTok Technology Co., Ltd. Tianjin

simply put forward: the algorithm of shaking is actually a funnel mechanism, which is basically consistent with the principle of recommendation algorithm of the headline's de centralization. Tiktok / BR > it has three tiktok steps:
first, cold start flow cell exposure
assume that 1 million people are uploading short videos every day on the jitter, and the jitter will randomly assign each cold video to a cold start flow pool with average exposure. For example, after each short video is released through audit, there are an average of 1000 exposures
Second, data selection
tiktok will analyze 1000 points of exposure from 1 million short videos, analyze the data of points, attention, comment, forwarding and so on, and pick out videos with more than 10% indicators, and then distribute 100 thousand times on average. Then go to see which are like, follow, forward and comment more than 10%, and roll into the next round of larger flow pool for recommendation
Third, the boutique recommendation pool
through round after round of verification, short videos with extremely high like rate, playback completion rate, comment interaction rate and other indicators are screened out to have the opportunity to enter the boutique recommendation pool. When users open the pool, they can see videos with tens of millions of likes
all the dry goods and skills shared next are closely around the core point: by increasing the number of likes, attention, comments, forwarding rate and other indicators, we can get more accurate official recommendations and win more exposure.

5. Tiktok is a de centralized algorithm platform, which means that any account has the opportunity to have millions of fans and even millions of fans. Even if we don't have any traffic, as long as our content is popular, more and more people will pay attention to it. So if you do the content in the right way, you can earn the first barrel of gold in the tiktok. If you don't know anything, please ask me in private

Decentralization means no center

extended meaning: with the deepening of the interaction between subject and object, the continuous balance of cognitive function and the continuous improvement of cognitive structure, the indivial can be released from the egocentric state, which Piaget calls decentralization

This kind of open, flat and equal system phenomenon or structure is called decentralization

extended data:

in a system with many nodes, each node has the characteristics of high degree of autonomy. Nodes can connect freely to each other to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form nonlinear causality through the network. This open, flat and equal system phenomenon or structure is called decentralization

with the deepening of the interaction between subject and object, the constant balance of cognitive function and the continuous improvement of cognitive structure, the indivial can be released from the egocentric state, which is called decentralization

1. Efficiency is different: the efficiency of decentralized network is higher than that of centralized network, but conversely, the security of centralized network is higher. On the whole, centralized network is suitable for high security applications

2. Different characteristics: centralized network means that each time two client computers communicate with each other through the server. The decentralized network is the initial need to go through the server, later communication does not need the server

3. Different costs: the characteristics of collective maintenance of blockchain can rece a lot of costs. The centralized network involves the maintenance, confidentiality, operation and so on of many systems, which must require a lot of human, financial and material resources. These things do not exist for the decentralization of blockchain, so they can save a lot of costs

extended materials:

precautions:

in the aspect of blockchain governance, an interesting trend recently is the re emergence of online virtual currency holder voting as a multi-purpose decision-making mechanism. Sometimes the vote of the coin holder is used to decide who runs the super node of the network (e.g. dpos in EOS, Neo, lisk and other systems), sometimes the protocol parameters are voted (e.g. the upper limit of Ethereum fuel supply), and sometimes the vote and direct application of approval (e.g. tezos) protocol upgrade are also concted

in all these cases, voting is automatic, and the protocol itself contains all the logic needed to change the verifier set or update its own rules, and automatically responds to the voting results
