Great talk showing just how easily we can get a simple concept so wrong. Only comment would be the standardisation of the examples (when not illustrating boundaries) as I was easily confused when the baseline varied so much

Interesting to learn how much there is to dates and time in computing. Very informative, and has given me more to think about when working with time related code.

Great talk and audience participation made it better!

Very interesting and fun opening quiz. I really enjoyed the interesting date facts outside of a coding context. Very simple code examples and easy to follow. Possibly add a few more weird exceptions to look out for but appreciate time is difficult (dates too apparently!!)

Good talk, it’s obviously a really complicated topic and hard to cover!

I think you showed the cat example too early, it shows a complex network with lots of features before we’ve seen a simple one.

I’d also suggest moving the Training explanation after showing an example of the XOR net with correct weight and bias, so we know what we’re working towards.

I’d also like to see an example of what the derivative and gradient changes for a single neuron. My lack of maths understanding means the last section looked like “do stuff to network until magic numbers give correct output”.

Fantastic talk, great I sight into DateTimeImmutable especially as I've fallen into the trap of DateTime. I'm looking forward to Dericks next book. A bit of feedback is remembering what slides you have (the last one did sneak up), but otherwise thoroughly enjoyable

I live for this subject! I loved audience participation.
I've enjoyed learning both what I can do and what I should do. Excellent delivery! Can't think of any improvements... would have liked a gif?
Thank you!!!

Great intro to a subject I had no idea about. Did get a bit mathsy but I guess it had too. The code was difficult to follow with the maths so perhaps split them a bit more for those that the maths over complicates things. Great delivery and clearly a strong understanding. No need for the disclaimer at the start :)

Excellent talk, slides were presented well, and Vítor knew his stuff. Some of the math involved did get a little complex, and I had to remember my A level maths course (which I did 20 years ago). Also, was a little rushed at the end, but this was due to the time limit imposed. Otherwise great talk, and I'm going to have a play with the code

Excellent - a simple enough example to cover in the time, and clear code to see how it’s done. Some more links to explanations on differentiation would have been good.
