In machine learning, supervision is particularly useful when data samples are labeled. If a the desired output for a sample x is y, then a supervised learning algorithm attempts to approximate a function f that produces a similar output yˆ, (1.1)yˆ=f(x). The algorithm is said to ...
经典算法:the Apriori algorithm and k-Means.(这个专用名词就不翻译了)3. Semi-Supervised Learning(半监督学习) 顾名思义,半监督学习意味着训练数据有一部分有标签,而一些没有,一般而言,当训练数据量过少时,监督学习得到的模型效果不能满足需求,因此用半监督学习来增强效果。 经典问题:classification and regressio...
Finding the ground state of a quantum many-body system is a fundamental problem in quantum physics. In this work, we give a classical machine learning (ML) algorithm for predicting ground state properties with an inductive bias encoding geometric localit
相机好不清楚(自用) 几种度量空间距离的方式: PCA (Principle component analysis) LDA(linear discriminant analysis) K-NN(k-NearestNeighbor) LLE(Locally Linear Embedding) MDS/IsoMap 测地线 LPP(localit…
作为新兴起的、高度灵活的一种机器学习算法,随机森林(Random Forest,简称RF)拥有广泛的应用前景,从市场营销到医疗保健保险,既可以用来做市场营销模拟的建模,统计客户来源,保留和流失,也可用来预测疾病的风险和病患者的易感性。最初,我是在参加校外竞赛时接触到随机森林算法的。最近几年的国内外大赛,包括2013年百度校园...
本文介绍朴素贝叶斯分类器(Naive Bayes classifier),它是一种简单有效的常用分类算法。 一、病人分类的例子 让我从一个例子开始讲起,你会看到贝叶斯分类器很好懂,一点都不难。 某个医院早上收了六个门诊病人,如下表。 症状 职业 疾病 打喷嚏 护士 感冒 ...
The OOB error is a bootstrap aggregation-based approach for assessing the prediction error of random forests, boosted decision trees, and other machine learning models85. Boruta algorithm The Boruta algorithm was introduced by Kursa and Rudnicki86. This technique attempts to reduce misleading outcomes...
根据题干关键信息定位到文章第五段的 The atmospheric (大气的) data was put into a machine learning algorithm (计算程序), which compared it to records of lightning strikes. 由此可知,大气数据被放入机器学习算法中,该算法将其与雷击记录进行比较。故这里的 it 代指 the atmospheric data。 故正确答案为 ...
