Factorization Machine (因子分解机)是Steffen Rendle在2010年提出的一种机器学习算法,可以用来做任意实数值向量的预测。. 对比SVM,基本的优势有:. 非常适用与稀疏的数据,尤其在推荐系统中。. 线性复杂度,在large scale数据里面效率高. 适用于任何的实数向量的 ...
WebbFactorization Machine因子分解机(Factorization Machine, FM)是由Steffen Rendle提出的一种基于矩阵分解的机器学习算法。目前,被广泛的应用于广告预估模型中,相比LR而言,效果强了不少。我们可以认为,这个模型结合了SVM的优点与分解模型的优点。与SVM类似的是,FM是一个广泛的预测器,可以兼容任意实值的 ... WebbHere’s how to install them using pip: pip install numpy scipy matplotlib scikit-learn. Or, if you’re using conda: conda install numpy scipy matplotlib scikit-learn. Choose an IDE or code editor: To write and execute your Python code, you’ll need an integrated development environment (IDE) or a code editor.
