Cosine similarity, cosine distance explained | Math, Statistics for data science, machine learning

Cosine similarity, cosine distance explained in a way that high school student can also understand it easily. If you have aspirations of becoming a data scientist, you must know these two concepts. I will explain cosine similarity using a real life simple example and then we will write code in python using sklearn library.

I started to miss your tutorials .. thank God you are back.. I know you are a busy man 😊.. keep going

[jayhu]

You make this topic understandable. Many thanks.

[alagappank]

Sir please continue data structure and algorithm in python series sir....

[jaysoni]

Please make videos on hypothesis test and it's parameter with theory and practical with real world use case i can understand theory wise but my mind can not accept it because i don't know how real world practical wise in data science field this use so i think your are the only one on earth who can explain this in much better way with real world practical use case.

You must explain the meaning of *cosine similarity negative* and how to interpret it

[venkatram]

You have shifted to maths after 7 videos in this playlist. That's all the stats I need for data science? OR you are covering only for beginners? I am a beginner and I want to know if I need to know more than what you covered in your playlist. Thanks.

[sofio]

thank you so much for this clear explanation!

[laxmipriyasahu]

Thank you sir for the clear explanation

Excellent explanation!
The only part that was not clear for me is when the similarity is -1. Does it mean that when we are calculating the distance of vector with cos similarity -1, it will result 2?

Please add new videos to this playlist about chi square and other points

[shibabrataghosh]

Sir please make a video on GitHub copilot as a threat to programmer's job

[Akshay-vquv]

Please keep using memes and cartoons to explain concepts in your videos. You are amazing.

[CuriousCommunityYT]

When will videos will come on chi square, p test ??

[programmingwithjackchew]

can I say the negative value of cosine similarity is one variable move opposite of another variable for example if one variable increases then another variable decrease, so it has similarity but just in the opposite way?

[rutikalalakiya]

while importing sklearn, the error i got is : AttributeError: module 'numpy.linalg._umath_linalg' has no attribute '_ilp64', how to solve this ?

[archerrozarioj]

Can cosine similarity be used for comparing financial transactions???

[ryuji]

is there any articles or journals that lead to theoretical of the cosine similarity and the cosine distance?

[timepassgamer]

Can anyone tell me Why cosine is used for similarity not sin?

[rupiyaldekai]

can you do pytorch implementation for ann.and fuzzy systems.please sir

[pveeranjireddy]

Please make basic math videos.we are not able to understand
