Support Vector Machines Part 1 (of 3): Main Ideas!!!

Support Vector Machines are one of the most mysterious methods in Machine Learning. This StatQuest sweeps away the mystery to let know how they work. Part 2: The Polynomial Kernel: https://youtu.be/Toet3EiSFcM Part 3: The Radial (RBF) Kernel: https://youtu.be/Qc5IyLW_hns NOTE: This StatQuest assumes you already know about... The bias/variance tradeoff: https://youtu.be/EuBBz3bI-aA Cross Validation: https://youtu.be/fSytzGwwBVw ALSO NOTE: This StatQuest is based on description of Support Vector Machines, and associated concepts, found on pages 337 to 354 of the Introduction to Statistical Learning in R: http://faculty.marshall.usc.edu/gareth-james/ISL/ I also found this blogpost helpful for understanding the Kernel Trick: https://blog.statsbot.co/support-vector-machines-tutorial-c1618e635e93 For a complete index of all the StatQuest videos, check out: https://statquest.org/video-index/ If you'd like to support StatQuest, please consider...
