Naive Bayes Algorithm 朴素贝叶斯算法。 朴素贝叶斯是一种简单但功能强大的预测建模算法。该模型由两种类型的概率组成,可以直接从训练数据中计算:每个类的概率。每个类给定每个x值的条件概率。一旦计算出概率模型,就可以利用贝叶斯定理对新数据进行预测。 当你的数据是实值时,通常假设高斯分布(钟形曲线),这样你就可以...

Naive Bayes is a popular (baseline) method for text categorization, the problem of judging documents as belonging to one category or the other (such as spam or legitimate, sports or politics, etc.) with word frequencies as the features. With appropriate preprocessing, it is competitive in this...
In simple terms, a Naive Bayes classifier assumes that the presence of a particular feature in a class is unrelated to the presence of any other feature. The Naive Bayes classifier is a popular supervised machine learning algorithm used for classification tasks such as text classification. It ...

The naïve Bayesian method is a classification method based on Bayes’ theorem and characteristic condition-independent hypothesis. Recent studies have often employed Bayesian models to diagnose psychiatric disorder...
The Microsoft Naive Bayes algorithm is a classification algorithm based on Bayes' theorems, and can be used for both exploratory and predictive modeling. The word naïve in the name Naïve Bayes derives from the fact that the algorithm uses Bayesian techniques but does not take into account de...
Naive Bayes Algorithm 朴素贝叶斯的核心基础理论就是贝叶斯理论和条件独立性假设,在文本数据分析中应用比较成功。朴素贝叶斯分类器实现起来非常简单,虽然其性能经常会被支持向量机等技术超越,但有时也能发挥出惊人的效果。所以,在将朴素贝叶斯排除前,最好先试试,大家常将其作为一个比较的基准线。本文会结合垃圾邮件分...
