Hi, good idea not to edit the typo part of the video. It serves to illustrate what often happens in real life coding... ;)

[karangori]

can you make a video about divisive clustering and finding divisive coefficient

[veritas]

that is not from scratch, or step by step cause is using dendogram as a special function

Hi, this video is awesome, I have a question: How to measure the accuracy for Hierarchical Clustering in python?

[saverioguzzo]

Nice job!
What if had categorical variable?

[josephkarianjahi]

Another great video from you. Thank you

[sadraavestan]

Hi, thank you for sharing this video. It was so helpful, but can you please also explain how to find and show the centroids of the cluster on the scatter plot.

i was looking for this. since very long

Hey Kindson The Tech Pro, the model accuracy is really low, 0.255.

# standardizing the data:
import sklearn.metrics as sm
from sklearn.preprocessing import StandardScaler
x =

# note this also changes the way the dendrogram looks
dendrogram = sch.dendrogram(sch.linkage(x, method='ward'))

y_hc = hc.fit_predict(x)

# checking for accuracy
sm.accuracy_score(dataset[1], y_hc)

# output: 0.33

When I standardize the data it goes up to 0.33 that's not much of an improvement.
Any idea how to fix this?

@kindson the tech pro please share the video on how to find the centroids in hierarchial clustering

[zahrasiraj]

hi kindson can you help me in making cluster for text documents ? how would i upload my own data for this purpose? and aply heirarchicle clustering plus its accuracy and relevance measurements ?

[SidTheBot]

so what is difference b/W K-means method and aglomirative method

[husnamohamed]

How optimal number of clusters can be find from dendrogram?

[merhaday]

Good job. Could you perform Space-Time Hierarchical Clustering in python. This is new algorithm and we want to learn how its code?

[vivian]

Hi, this video is awesome, it really helps me understand the Hierarchical.

[albarrahassan]

Keep it up, very informative and clear explanations.

[omkarshende]

what if you have multidimensional data example 40 or to apply clustering for that
