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.

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 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.

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?

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?

@w14141 Жыл бұрын

Ah you explained it. When we are talking about distance we are not concerned with the vector direction. So talking about distance an angle of 180° between vectors is like an angle of 0°. I think that's it.

Hey Punna to be honest I am spending too much time in making these presentations and they are proprietary content. In past I have seen people bluntlessly copy my content make tutorials and sell them for commercial gain without giving necessary credits hence I have decided to not share these. Hope you understand my situation.

what is the difference between reinforcement learning and deep learning?

@its_kumar 3 жыл бұрын

In deep learning we design our own Model using neural networks. In reinforcement learning we train the machine or ai bots to accomplish some task in the similar way as we train a dog 🐕, Basically it based on reward and punishment.
