1 引言 机器学习(Machine Learning)是人工智能(AI)的重要组成部分,目前已广泛应用于数据挖掘、自然语言处理、信用卡欺诈检测、证券市场分析等领域。量化投资作为机器学习在投资领域内最典型的应用之一,已经越来越广泛的出现在我们的视野中。 机器学习可简单理解为利用统计模型或算法拟合样本数据并进行预测,其模型算法根据...
Q2: What is the difference between supervised and unsupervised machine learning? 问题2:监督学习和非监督学习有什么不同? 监督学习需要train有label的数据。例如,为了进行classification(一项受监督的学习任务),您需要首先标记将用于培训模型的数据,以便将数据分类到标记的组中。相反的,无监督学习不需要明确标记数据。
