AI Thread Summary
The discussion revolves around the use of vector calculus in the context of probability and machine learning, specifically in the textbook "Pattern Recognition and Machine Learning" by Bishop. The author notes that the vector calculus presented in the book differs from traditional teachings, as it includes derivatives and integrals with respect to vectors. Participants confirm that the concepts of curl, gradient, and divergence are indeed part of vector calculus. Recommendations for further reading include a textbook by Jerrold E. Marsden. The conversation highlights a desire for clarity on advanced vector calculus applications in probability theory.

Hi,
I'm reading through a probability textbook right now (Pattern Recognition and Machine Learning by Bishop) and it makes heavy use of "vector calculus".

"Vector Calculus" is in quotations, because it's unlike the vector calculus that I learned in my courses (gradients, curls, divergence, etc...).

There's lots of formulas where he literally takes the derivative of a function with respect to a vector. Or he integrates a formula with respect to a vector.

What field of mathematics is this? And are there any good books where can I learn more about it?

Thanks
-Patrick

Sounds exactly like "vector calculus", the way it should be. For a good textbook see http://www.chapters.indigo.ca/books/Vector-Calculus-Jerrold-E-Marsden/9780716749929-item.html?ref=Search+Books:+%2527vector+calculus%2527
 
Thank you for your help, I'm on my way to the library right now to get a copy of it.

As an aside then, are the Curl, Gradient, and Divergence properties also part of vector calculus? I scoured the internet for hours looking for the definition of an integral with respect to a vector, but the only results I came up with concerning "vector calculus" was regarding those three operators and their properties.

yup, they are.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
