First Step: Learn Python. Python is easy to learn. It's made so that you can begin making your own projects by having rudimentary knowledge regarding programming. Links of interest: Learn by doing. You can make progressively complex code by solving problems here. https://www.codeabbey.com Same thing, a little more math oriented: https://projecteuler.net For actual tutorials on the language you can visit: https://www.kaggle.com https://www.jetbrains.com/es-es/edu-products/learning/python/ https://www.hackerrank.com Second Step: learn to use pandas. The following link will be of use. https://mlcourse.ai Third Step: Learn to use Keras With TensorFlow: https://www.youtube.com/watch?v=qFJeN9V1ZsI https://www.youtube.com/channel/UC4UJ26WkceqONNF5S26OiVw
A few math topics you might need. These books are easy to find. Linear Algebra: Strang G. Linear algebra and its applications (recommended) Ray Kunze, Kenneth Hoffman. Introduction to Linear Algebra (if you are mathematically inclined) Vector Calculus: Any text really. I recommend Jerrold E. Marsden's Vector Calculus. Probability and Statistics: Sheldon Ross. A First Curse in Probability DeGroot. Probability and Statistics
As a programmer with a degree in mathematics, I'm not sure what this thread is about besides learning python. Given that I have both of these backgrounds already, why not explain what machine learning is, what it's useful for, and where tensors are involved?
>>39 not OP, but TensorFlow is just the name of google's machine learning library. I don't think ML typically uses tensors of order higher than 2, though I'm not actually in this field myself.

>>39 >with a degree in mathematics Can you please help me with my calculus assignment? I just need to solve at least one out of the three to pass. The textbook is Hildebrand, Francis. Advanced Calculus for Applications. 2nd ed, for reference. Is due in 2 weeks. Help a nigga out You have my sworn allegiance. Regards.
>>42 Well thanks for saying how you're probably going to spam this site retard, at least try to blend in. Lolcow uses vichan with no captcha anyway.
>>41 Okay so 21 doesn't look too horrible. The question gives you instructions. I'll just reword them slightly. Rewrite I(z) as the sum of the integral from negative infinity to zero and the integral from 0 to positive infinity (just change the bounds of the integral), and expand the f(gamma) using the given definition. Then you have I(z) on the left and a tortured integral with an f(x) term on the right. In theory then you would just have to rearrange and solve until you get to I(z)=f(z), I suspect you're going to have to differentiate both sides (those e terms are asking for it) and spot some identities, note the similarity in form between the two integrals shown on the page and consider how substitution of variables will play out when combining them. Now that I've thought about all that it's probably easier than it looks, but I'm still not going to pull out a sheet of paper and solve it for you. For the second part of the question consider that f(z) is not differentiable outside the bounds (a, b) and this may be a trick question.
I'm also going to recommend deriving I'(z) as a function of I(z) at some point, I feel like that might be a useful trick here. But I'm actually doubleposting to link to https://www.physicsforums.com/ If I was ever completely stumped by something or didn't know where to begin the above site is like asking a crowdsourced lecturer for help. They won't solve things for you completely either but they do try to be helpful.
