Machine learning algorithms (1)(URL: https://www.analyticsvidhya.com/blog/2017/09/common-machine-learning-algorithms/ ) Broadly, there are 3 types of Machine Learning Algorithms.. 1. Supervised Learning監督學習 • How it works: This algorithm consist of a target / outcome variable (or dependent variable)目標/結果變量（或因變量） which is to be predicted from a given set of predictors (independent variables)一組給定的預測變量（獨立變量). Using these set of variables, we generate a function that map inputs to desired outputs生成一個函數將輸入對應的到輸出. The training process continues until the model achieves a desired level of accuracy on the training data. • Examples of Supervised Learning (analytical model): Regression回歸, Decision Tree, Random Forest隨機森林, KNN, Logistic Regression邏輯回歸etc.

Machine learning algorithms (2)(URL: https://www.analyticsvidhya.com/blog/2017/09/common-machine-learning-algorithms/ ) 2. Unsupervised Learning無監督學習 • How it works:In this algorithm, we do not have any target or outcome variable to predict / estimate沒有任何目標或結果變量來預測/估計. • It is used for clustering population用於群集人口in different groups, which is widely used for segmenting customers細分客戶in different groups for specific intervention. • Examples of Unsupervised Learning (analytical model): Apriori algorithm, K-means. 3. Reinforcement Learning強化學習: • How it works: Using this algorithm, the machine is trained to make specific decisions. • It works this way: the machine is exposed to an environment where it trains itself continually using trial and error通過試驗和錯誤不斷訓練自己. • This machine learns from past experience and tries to capture the best possible knowledge to make accurate business decisions捕捉最佳可能的知識以做出準確的業務決策. • Example of Reinforcement Learning (analytical model): Markov Decision Process馬爾科夫決策過程
