1 - Teaching you the fundamentals of machine learning and deep neural networks.
2 - Helping you understand the latest cutting edge research in the field of computer vision.
3 - Implementing code and building production ready applications using the latest open source frameworks and libraries in the field of machine learning.
Finally someone who understands it. I can`t believe how people lack ground knowledge in plotting functions, but are already studying Maschine Learning. Thank you very much.
Unfortunately, mathematicians cannot explain mathematics to non-mathematicians 😅. If i would explain the Sigmoid function clearly, I would start with the problem itself and what should be solved, before I start with any numbers and formulas.
so in other words, the sigmoid function should be used only WHILE training, then testing should just use a comparison operator to see if the value is more or less than 0.5?
