This study aims to compare the performance of multiple linear regression and machine learning algorithms for predicting manure nitrogen excretion in lactating dairy cows, and to develop new machine learning pre
Mostmachine learning (ML)models either classify data (e.g.,does this image contain a cat or a dog) or make predictions (e.g.,what will the temperature be next week). All ML models that make predictions rely on regression algorithms to analyze provided data, identify relationships between re...

机器学习基础算法python代码实现可参考:machine_learning_algorithms 1 原理 1.1 引入 线性回归是最为常用的一种数据分析手段,通常我们拿到一组数据后,都会先看一看数据中各特征之间是否存在明显的线性关系。例如,现在我们拿到了一组学校中所有学生基本资料的数据,该数据以二维表格的形式呈现,如下表所示。 示例数据表 每...
Survival prediction is an important problem that is encountered widely in industry and medicine. Despite the explosion of artificial intelligence technologies, no uniformed method allows the application of any type of regression learning algorithm to a s
Four machine learning algorithms, namely artificial neural networks (ANN), random forest regression (RFR), support vector machine regression (SVR), and Gaussian process regression (GPR), were found to estimate biophysical and biochemical variables of unseen targets with high performance (relative error...
Regression inmachine learningis a technique used to capture the relationships between independent and dependent variables, with the main purpose of predicting an outcome. It involves training a set ofalgorithmsto reveal patterns that characterize the distribution of each data point. With patterns identifi...
