1, big data and other core key technologies: 32 algorithms A* search algorithm-graphic search algorithm, which calculates the path from a given starting point to a given ending point. In this paper, heuristic estimation is used to estimate the best path for each node to pass through the node and arrange orders for each location.
2. The algorithm of big data mining: Naive Bayes, super simple, just like doing some counting work. If the conditional independence hypothesis holds, NB will converge faster than the discriminant model, so you only need a small amount of training data. Even if the hypothesis of conditional independence is not established, NB still performs surprisingly well in practice.
3. Big data technology system is huge and complex, and its basic technologies include data acquisition, data preprocessing, distributed storage, database, data warehouse, machine learning, parallel computing, visualization and so on.
4.Apriori algorithm is the most influential algorithm for mining frequent itemsets of Boolean association rules. Its core is a recursive algorithm based on the idea of two-stage frequency set. This association rule belongs to single-dimensional, single-layer and Boolean association rules in classification. Here, all itemsets with support greater than the minimum support are called frequent itemsets, which is called frequency sets for short.

What about cloud measurement data?
Cloud measurement data is the head manufacturer of AI training data service, which has been widely recognized by customers, media and other circles. It is a powerful and representative AI data collection and data labeling resource service provider in the industry.
Cloud measurement data is a manufacturer focusing on high-quality scenario-based AI training data services, helping to train "good AI" by producing "good data".
Another service, AI training data service, is also the leader of the current track, and its cloud measurement data labeling platform has the highest labeling accuracy of 999%, which is the highest accuracy known in the industry. Corporate care: It is understood that five insurances and one gold, weekends, flat management, annual physical examination, supplementary medical care, birthday party gifts, etc.
From the current communication with peers, the data quality and process control of cloud measurement data delivery are first-class. The most important thing in doing business services is delivery and service. They have accumulated so many years of service experience. Logically speaking, it is not surprising to engage in AI data services, and I believe they can do it well.
What are the most commonly used algorithms for big data?
Discrete differential algorithm.
The algorithm of big data mining: Naive Bayes, super simple, just like doing some counting work. If the conditional independence hypothesis holds, NB will converge faster than the discriminant model, so you only need a small amount of training data. Even if the hypothesis of conditional independence is not established, NB still performs surprisingly well in practice.
Branchandbound)-algorithm-an algorithm for finding specific optimization solutions in various optimization problems, especially suitable for discrete and combinatorial optimization.
Visualization of data mining algorithm is for people, and data mining is for machines. Clustering, segmentation, outlier analysis and other algorithms allow us to dig deep into data and value. These algorithms not only have to deal with large amount of data, but also deal with large data speed.
Big data algorithm is not neutral, but what does it have?
1, it's too late. When the whole market is talking about big data risk control and touting machine learning, the crisis has quietly arrived. Not only financial technology companies are talking, but also internet giants and the entire banking circle are talking.
2. Authenticity: the quality of data. Complexity: The amount of data is huge and the sources are diverse. Value: Make rational use of big data to create high value at low cost.
3. Big data technology refers to the ability to quickly obtain valuable information from various massive types of data. Technologies suitable for big data include MPP database, data mining power grid, distributed file system, distributed database, cloud computing platform, Internet, extensible storage system and so on.
