Naive Bayes vs Logistic Regression by Sanghamitra Deb

Witryna28 mar 2024 · Naive Bayes classifiers are a collection of classification algorithms based on Bayes’ Theorem. It is not a single algorithm but a family of algorithms where all of them share a common principle, i.e. … Witrynanamely; logistic regression, k-nearest neighbor, and naïve bayes, for finding suspicious behavioural patterns in fraud data. The principal component analysis act as feature re-duction technique before the processed data is injected into the classifiers. A higher accuracy was accrued by k-nearest neighbor to other models.

Witryna21 kwi 2015 · (1) Naive Bayes是一个生成模型，在计算P (y x)之前，先要从训练数据中计算P (x y)和P (y)的概率，从而利用贝叶斯公式计算P (y x)。 Logistic Regression是一个判别模型，它通过在训练数据集上最大化判别函数P (y x)学习得到，不需要知道P (x y)和P (y)。 (2) Naive Bayes是建立在条件独立假设基础之上的，设特征X含有n个特征属 … Witryna2 paź 2013 · The complexity of a logistic regression classifier is identical to the Naive Bayes classifier if the event space is the same---they form a generative/discriminative pair, and have identical forms of classification rule.

That is, you find the weights β 0, β 1 that maximizes how likely your observed data is. There is no closed form solution to the MLE, so you need to use iterative methods. This gives you a single point estimate of our weights.
