I. Introduction of AdaBoostBoosting, also known as enhanced learning or ascension, is an important integrated learning technique that can enhance the predictive accuracy of weak learners with a slightly higher predictive precision than random guessing, which is very difficult to construct strong learners, and provides an effective new idea and method for the design of learning algorithms. One of the most successful applications was the AdaBoost algorithm proposed by YOAV Freund and Robert Schapi

to adopt the strategy of how to store the data. Aggregation is designed to put together data that is often accessed concurrently, so aggregations can be used as a distributed unit of data. How to distribute aggregated data evenly across different machines may sometimes require "domain-specific rules," and many NoSQL databases already provide "auto-sharding (auto-sharding)", which is responsible for distributing data to each shard by the database. and directs the data access request to the appro

improve the performance of naive Bayesian classifiers: If the continuous feature is not normally distributed, we should use a variety of different methods to convert it to a normal distribution. If the test dataset has a "0 frequency" problem, apply the smoothing technique "Laplace estimate" to correct the data set. Deleting a recurring height-dependent feature may result in loss of frequency information and effects. Naive Bayesian classification has limited choice in param

limited to drinking. Onion The sulfur compound in the onion is a potent antibacterial ingredient, which is found in test tubes that can kill a variety of bacteria, including causing us to decay. The strain of the tooth is streptococcus, and the fresh onion has the best effect.How to eat? It is recommended to eat half a day of raw onions, not only to prevent cavities, It also helps lower cholesterol, prevent heart disease and boost immunity.

the rows in order to work correctly, you must not use multithreading. "Sort rows", "Unique rows" and "Rowdenormalizer" are the best examples. There is no point in using multithreading for these steps, because each thread processing row is just a subset of all rows.ConclusionKettle allows each individual definition of multiple threads to execute in a transformation, and can also set input and output queue sizes, and two features are useful for boosting
