How to Perform Hierarchical Clustering in Python( Step by Step)

[@josephkarianjahi1467]

Another great video from you. Thank you

[@linda_erose]

exactly what i was looking for

Good you found this! Do remember to subscribe to my channel for more like this 😄

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 = StandardScaler().fit_transform(points)
# 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?

i was looking for this. since very long

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

[@vivian60635]

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

[@albarrahassan2354]

Keep it up, very informative and clear explanations.

[@karangori7897]

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

[@TheAnbohan]

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

[@zahrasiraj106]

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 ?

[@saverioguzzo6144]

Nice job!
What if had categorical variable?

[@sadraavestan5344]

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.

[@KindsonTheTechPro]

Yes, sure. Remember to subscribe to get notified.

[@sadraavestan5344]

@@KindsonTheTechPro thank you. I found how to do that

[@amritakaul87]

Hi, can you please share the solution of how to find the centroids in hierarchical clustering ? Thanks in advance

[@Ankurkumar14680]

Very good amazing video

[@amritakaul87]

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

[@SidTheBot]

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

[@himalayasinghsheoran1255]

Great video.

[@brianadams2862]

nice job champ

[@KindsonTheTechPro]

Thanks

[@husnamohamed]

How optimal number of clusters can be find from dendrogram?

[@omkarshende6217]

what if you have multidimensional data example 40 or 50.....how to apply clustering for that

[@richardramsell3928]

this is my question

[@oddnumber8149]

do y have a link with the code ?

[@shimulpasha7285]

Can I get the code link??

[@KindsonTheTechPro]

Sure! Please find the codes here in my github repo github.com/KindsonTheGenius/hierarchical-clustering-python

[@Mhtt3463]

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

[@pranitpokhrel470]

Amazing

[@veritas2162]

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

[@settishivamahalakshmi5473]

Agglomerative is not defined

[@olfadaikhi2969]

Bonsoir
