in mind, the algorithm proceeds in a trial-and-error process. Each move receives positive, negative, or neutral feedback, which the algorithm uses to hone its overall decision-making process. Reinforcement learning algorithms can work on a macro level toward the project goal, even if that ...
Underfitting is the opposite of overfitting in that the machine learning model doesn't fit the training data closely enough, thus failing to learn the pattern in the data. Underfitting can be caused by using a too-simple model for a complex problem. In the above example where a company evalu...

Boosting inmachine learningis a technique for training a collection ofmachine learning algorithmsto work better together to increase accuracy, reduce bias and reduce variance. When the algorithms harmonize their results, they are called anensemble. The boosting process can work well even when each alg...

无监督学习 Unsupervised Learning 无监督学习使我们能够在很少或根本不知道我们的结果应该是什么样子的情况下解决问题。 我们可以从不一定知道变量影响的数据中推导出结构。 我们可以通过基于数据中变量之间的关系对数据进行聚类来得出这种结构。 对于无监督学习,没有基于预测结果的反馈。 Unsupervised learning allows us ...
