Wonderful visualizations

[@supersuperintendant]

Excellent explanations. Thanks!

Excellent visualizations showing the danger of localized minima on the error surface. I used a levenberg marquardt / gaussian model to help explain chemical reactions - but that was over 25 years ago :)

If we're being pedantic about correct pronounciation of Χ it's definitely not /ˈkaɪ/, but rather [kʰ]. As in loch.

You need to make it more dramatic. "Please say it correctly or I will hunt you down and make you pay!!!" ... Oh and brilliant youtube.

[@Evan490BC]

Please don't pronounce "χ" as "kai", it's wrong! The actual sound is "chee", where the initial letter sounds more like the "h" in "horse", for example.

"Please pronounce it correctly" - pronounces "chee-square" as "kai square"...
