I merged 3 different CSV(D1,D2,D3) Netflow datasets and created one big dataset(df), and applied KMeans clustering to this dataset. To merge them I did not use pd.concat because of memory error and solved with Linux terminal.
df = pd.read_csv('D.csv') #D is already created in a Linux machine from terminal ........ KMeans Clustering ........ As a result of clustering, I separated the clusters into a dataframe then created a csv file. cluster_0 = df[df['clusters'] == 0] cluster_1 = df[df['clusters'] == 1] cluster_2 = df[df['clusters'] == 2] cluster_0.to_csv('cluster_0.csv') cluster_1.to_csv('cluster_1.csv') cluster_2.to_csv('cluster_2.csv') #My goal is to understand the number of same rows with clusters #and D1-D2-D3 D1 = pd.read_csv('D1.csv') D2 = pd.read_csv('D2.csv') D3 = pd.read_csv('D3.csv')
All these datasets contain the same column names, they have 12 columns(all numerical values)
Example expected result:
cluster_0 has xxxx numbers of same rows from D1, xxxxx numbers of same rows from D2, xxxxx numbers of same rows from D3?

Answer
cluster0_D1 = pd.merge(D1, cluster_0, how ='inner') number_of_rows_D1 = len(cluster0_D1) cluster0_D2 = pd.merge(D2, cluster_0, how ='inner') number_of_rows_D2 = len(cluster0_D2) cluster0_D3 = pd.merge(D3, cluster_0, how ='inner') number_of_rows_D3 = len(cluster0_D3) print("How many samples belong to D1, D2, D3 for cluster_0?") print("D1: ",number_of_rows_D1) print("D2: ",number_of_rows_D2) print("D3: ",number_of_rows_D3)
