Hi all,
thank you for the excellent repo!

I'm going through the little learner now and it's amazing!

should (define line-xs [2.0 1.0 4.0 3.0]) and (define line-ys [1.8 1.2 2.3 3.3]) in chapter 1 of the little learner be
(define line-xs '[2.0 1.0 4.0 3.0]) and (define line-ys '[1.8 1.2 2.3 3.3]), respectively?

The square brackets are a notation we use in the book to save space. To type it into code, use (tensor ...).

thank you.

Also, we never use quote quasiquote and any other related operator in either the punctuation or written out forms

On page 26 the final version of line uses \theta unicode 03B8 ? does racket allow the use of that, should I be using that in my code when writing it out or is it a short hand like described on page xxiii. The last para on that pages says it should be written out as a-hat,c-hat,big-theta,et al ; but then goes on to say unicode can be used in names of formals, functions and keywords?

I wish the λ character was able to be use in other schemes and common lisp and I want that key on my keyboard (just sayin')

page 64:frame 28 dot point 3
Is that a typo should it read ((line (tensor 2.0 1.0 4.0 3.0)) (list 0.0 0.0))
not ((line (tensor 2.0 1.0 4.0 3.0) (list 0.0 0.0))
. ^{miss matched brackets}

Hi and good to be here!

Currently working through the book and enjoying it a lot!
It's just what I wanted and at pretty much the level I wanted. I am fairly comfortable in Scheme, I know a little about AD, but almost nothing of ML.

I am currently just at the end of Ch 9. I found a little problem I got stuck on, which is what led me here. I like the way the book has progressed so far, building and building on the gradient-descent function. Reading ahead a bit, it just looks like it's getting better and better. Looking forward to it.

Many thanks to all involved.
