Very helpful video.Thanks Aman.

Thank You Sir , simple and clear as always

Nice Tutorial.... Thanks a lot

I always follow your classes regularly. i always miss SVM ( hard and soft ) lectures can u pls make videos on that. there is no much information available in KZbin ...

[@UnfoldDataScience]

Sure.

Excellent explanation. I started watching your videos when you had 1k subscribers. Now it turned into 35k. It's pure hard work. Keep it up and thank you.

[@syednizamuddin9855]

thanks sir, the way you explain complex topics in simple terms is amazing

[@UnfoldDataScience]

Welcome Syed, pls share with friends as well.

Excellent explanation 👌 thank you. PCA comes under bucket 1 as it uses standardization ?

Thanks, Bro ... for clarifying the concept of Standardscaling and MinMax Scaling ..... :-)

Way out east there was this fella I wanna tell ya about. Fella by the name of Unfold Data Science. At least that was the handle his loving parents gave him, but he never had much use for it himself. This Unfold Data Science, he called himself The Dude. Now, "Dude", there's a name no one would self-apply where I come from. But then, there was a lot about the Dude that didn't make a whole lot of sense to me. And a lot about where he lived, likewise. But then again, maybe that's why I found the place so durned interestin'. They call New Delhi the "City Of New Threshold", but I didn't find it to be that, exactly. But I'll allow it as there are some nice folks there. 'Course, I can't say I seen London, and I never been to France. And I ain't never seen no Queen in her damned undies, as a fella says. But I'll tell you what... after seein' New Delhi, and this here story I'm about to unfold, well, I guess I seen somethin' every bit as stupefyin' as you'd see in any of them other places. And in English, too. So I can die with a smile on my face, without feelin' like the good Lord gypped me. Now this here story I'm about to unfold took place back in the late '10s - just about the time of our conflict with Coron-ese. I only mention it because sometimes there's a man... I won't say a hero, 'cause what's a hero? But sometimes, there's a man, and I'm talkin' about the Dude here, sometimes, there's a man, well, he's the man for his time and place. He fits right in there. And that's the Dude. In New Delhi. And even if he's a lazy man, and the Dude was most certainly that. Quite possibly the laziest in Delhi, which would place him high in the runnin' for laziest worldwide. Sometimes there's a man... Sometimes, there's a man. Ah, I lost my train of thought here. But... aw, hell. I done introduced him enough.

Is Feature Scaling apply on one single column or 2 columns combined? From your explanation, it seems like it will be applied on 2 columns combined.

[@rameshwarsingh5859]

supposedly , yes ,but in the real world there are thousands of columns and do feature engineering for take out important columns according to the precisiion of your knowledge and you can apply most used one std..it will distribute all the data points according to the graph

[@prajwalsyallur712]

Please, make a video on Standard Scalar and Min Max Scalar also.

[@UnfoldDataScience]

Sure Prajwal.

[@asitnayak636]

You told Normalization will get affected by outliers because in its formula we have the maximum no. . But in standardization, we use mean ... Which get easily affected by outliers. So why standardization is not affected by outliers ?

Dataset description: 4k images with two classes and balanced classes. Using this data set i trained two model using tiny-yolov4. Model 1 : trained all 4k images. 20k max_batches . getting 84% accuracy avg loss 0.12xxx Model 2: Cycle 1 :i trained 3k images with 20k max_batch getting 94% accuracy. Cycle 2 : i trained 1k images with 20k max batch using last weight of cycle 1. After completion i am getting 94% accuracy and avg loss 0.0xx. Even though i increased model: 1 20k+20k max batch thare is no improvement. My question is for both the model i trained with same dataset. why result is different. Training small dataset is good? Note: cfg file are same for both model. Computer configuration are same and gpu resources also same for both the model. Can you justify it... please Thanks.
