1 期末報告 Clustering DBSCAN
姓名:林楷能

2 Outline Algorithm Introduction Code Review Live Demo(Using InAnalysis)
Conclusion

3 Algorithm Introduction

4 DBSCAN Density-based spatial clustering of applications with noise
優點:不需要預先聲明聚類數量,過濾噪聲點 缺點:不擅於處理資料間過於密集的資料

5 Code Review

6 dbscan.py class sklearn.cluster.DBSCAN
(eps=0.5, min_samples=5, metric=’euclidean’, metric_params=None,  algorithm=’auto’, leaf_size=30, p=None, n_jobs=1)
