You may want to take a course in Linear Algebra before getting into ML. It won't make a lot of sense unless you have a basic understanding of matrices.
A good starting point would be https://www.coursera.org/learn/datasciencemathskills also this one doesn't cover matrices as far as I remember. Andrew NG's Machine Learning course (https://www.coursera.org/learn/machine-learning/home/week/1) also has a linear algebra section in week 1 to refresh your knowledge.
There are really some great books I love Mathematics - From the Birth of Numbers which is brilliant in that you get great scope & history. Also I highly value Schaum's outlines series : Linear Algebra (Fully solved problems) walks you thru certain problems and how to solve, then gives you problems to solve, you give it a spin and the answers are provided so you can verify accordingly. I think we also have to give a shout out to the for Dummies series which are are written be great people with great imaginations to convey a thought process in a fun manner.
Get the the library and have some fun !
Greetings Frederick,
What the product operation line is saying (equation 2.5) is the cell C_{i,j} is defined as the dot product of A's row i and B's column j.
A How To video is Intro to matrix multiplication (video) | Khan Academy. This is just the tip of the iceberg for linear algebra. As other commentators noted, a refreshing class on linear algebra might be helpful.
For a mathematical reason why the definition of matrix multiplication is the way it is, see https://math.stackexchange.com/questions/271927/why-historically-do...
Here is what I recommend when I'm mentoring and had good success with it
Ian GoodFellow is fairly advanced.
I would suggest you start with Grokking Deep Learning by Andrew Trask.
This book has the lowest barrier to entry possible in author's own words and I can attest he has achieved his mission.
https://www.manning.com/books/grokking-deep-learning
He breaks down all the concepts into extremely small and simple Intuition.
you will be doing Gradient Descent & Back Propagation in your sleep :)
After that, I would read Deep Learning with Python by François Chollet, creator of Keras
https://www.manning.com/books/deep-learning-with-python
Now you will be armed with DNN, ConvNet, RNN, GAN, and ML(Linear Regression, Logistic & Kernel Methods).
For Math, here are some resources I'm listing in relevance to Deep Learning
https://courses.edx.org/courses/course-v1:Microsoft+DAT256x+1T2018a...
https://www.khanacademy.org/math/linear-algebra
https://www.khanacademy.org/math/multivariable-calculus
You can spend years teaching yourself math, statistics, ML and DL. Pick a simple project and learn these concepts as a means, your learning will go far.
Good Luck!
Exactly. I was also stuck. It just shows the poor skills these professors have in writing textbooks. We have to think about newer technologies. One good example is there. 3Blue1Brown
thanks

I am in the same boat. Do I started linear algebra from MIT Open Courseware's Linear algebra course by Prof Strang.
