Normalization & Standardization
Apart from missing or outlier treatment, Dimensionality reduction, one-hot encoding, Data Transformation is an important part of Data pre-processing stage. If done effectively, this leads to improved model performance.
There are many such techniques like - Log or power transformation, Winsorization or clipping, Unit Vector scaling, etc. Each of them have mathematical basis which makes it more popular in one area than other.
This video talks about two popular techniques of Data Transformation - Normalization & Standardization. Both of them can easily be implemented using popular tools like Python, R, etc.

Parameters to create Dynamic Tableau charts (Part 1)
Переглядів 7633 роки тому
Tableau is a leading Analytics platform which helps leaders to see and understand data more efficiently. Creating Visual dashboards and generating insights is the final step in any data analysis life cycle. Any modern day Data Analyst or Data Scientist needs to be comfortable in interacting and creating these dashboards in order to be an effective story-teller. A parameter such as date, number ...
CDF and PPF in Python
Переглядів 14 тис.3 роки тому
This is a hands-on video in Python prepared by DataR Labs to understand the probability of an event occurring. The case study used to explain the concept uses the data from education institute imparting Data Science trainings. This video explains how to calculate probability of a given event under Normal data distribution using CDF function from SciPy and vice-versa using PPF function from SciP...
Recall and Precision - Evaluation Metrics for classification model
Переглядів 5363 роки тому
In this video, evaluation metrics for binary classification model has been explained. Recall and precision are better metrics to evaluate performance than accuracy when the dataset is unbalanced. The explanation has been done using an example data from credit risk modeling. For more such content on Data Science visit www.datarlabs.com.
Would it make sense to do a kruskal-wallis significance test for scaled indices that have been scaled 0-1 with min-max? Thank you ❤ (for microbial ecology study)
Hey sir thanks for simplifying these concept it was wracking my brain but once i watched the video now i understand the concept so clear.
Wow I am really grateful Sir…it’s very helpful
This is Great!! Thank YOU !! ^.^
very good explanation. Thank you very much !!! I really wanted to understand these concepts.
thank you for this. could you please upload the second part?
thank you for so simple explanation
Thanks for this ,Was much needed ! PLease keep posting your content , would really help people like me.
Where can I learn about the difference of (percent of total) and normalization. I find that I like my data to not stretch all the way to 0 or 1?
what is the benefit to scale down values between 0 to 1, can you please elaborate?
Great video Sir, can you please tell how to do the same in SPSS instead of Python. Regards
well explained, thanks 👍
Fantastic! Thank you so much!😊
you saved me!
Extremely beautiful explanation!
This is a really nice explanation. can you provide the CSV file/ link?
great content
Glad it helped!
nice explanation!
Simplest explanation on UA-cam
Glad you liked it
can you provide the data?
Apologies for the late reply! What data are you looking for?
@@datarlabs877The script phython for study. Thanks 😅
Great thanks f or this excellent video.
Great explanation Please upload more videos on.machine learning topics
Will upload soon
very clear! please post more
More such videos coming soon!
This is not fair that you don't do more videos about statistics and even advanced statistics. Please continue...
You're brilliant, man!
Very clear explanation. Thank you for this Anurag
