Plotting Functions: 提供了一系列绘图函数,用于可视化模型性能和数据分布,如混淆矩阵、决策区域等。 Association Rules: 实现了Apriori算法,用于挖掘交易数据中的频繁项集和关联规则。 mlxtend的设计理念是保持与Scikit-learn的高度兼容性和一致性,使得用户可以无缝地将mlxtend的功能整合到现有的Scikit-learn工作流中。这使...

mlxtend的关联规则挖掘模块提供了Apriori算法和FP-Growth算法。以下是一个使用Apriori算法进行关联规则挖掘的示例: from mlxtend.frequent_patterns import apriori, association_rules import pandas as pd data = pd.DataFrame([[1, 1, 0, 1], [0, 1, 1, 1], [1, 0, 1, 1]], columns=['A', 'B...

I think you should be able to get it to work by creating a python 3.7 env if you don't want to install the Python 3 version of Anaconda. I.e., what you can do is to execute the following and then try again: I'm trying to use the mlxtend package. I have installed mlxtend but...
