NEED HELP WITH SVM KERNEL CODE IN PYTHON FROM SCRATCH
Ask ChatGPT. It knows how to implement basic things. "I want to implement that, what would be the different steps in my program" then you ask more questions like "how do I write the kernel function" and so on. Just like when you program yourself, it's all about turning big problems into a sequence of smaller and simpler problems. If chat GPT can't directly solve the big problem, tell chat GPT to give you several steps and then ask chat GPT to solve a step. More on reddit.com

Implementing SVM and Kernel SVM with Python's Scikit-Learn
July 2, 2023 - In this article we studied the simple linear kernel SVM. We got the intuition behind the SVM algorithm, used a real dataset, explored the data, and saw how this data can be used along with SVM by implementing it with Python's Scikit-Learn library.

r/learnmachinelearning on Reddit: NEED HELP WITH SVM KERNEL CODE IN PYTHON FROM SCRATCH
December 13, 2023 -
Hi everyone
Sorry if what I am asking is elementary but I am new to machine learning and I have been asked to build a SVM classifier with Gaussian or Polynomial Kernel which solves the Dual Quadratic Problem from scratch without importing it directly from any library like sci-kit learn.
I understand the math behind it but since I am new to coding I am unable to find a comprehensive YT video since everyone just imports it from sci-kit learn, I tried finding books but they were from a long time ago and didn't have python implementation, I tried GitHub code, but in two instances that I found it, it was all over the place.
Can anyone link me up to a simple code or let me know where to search, I will be extremely appreciative of you.

Okay so if you dont know how to code in python why is the first thing you want to create is an SVM model from scratch? Also who wants you to code this from scratch, school or company? If school then I assume they gave you some guidance but it seems unlikely they want you to start coding with a hard task. If workplace then you should be able to do this or they require you to do a task that is not your job. So tell them you are not a programmer or ML engineer.
