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 :)

Excellent explanations. Thanks!

Wonderful visualizations

Excellent video. It helped me a lot

Nice explanation

Hi, please how can I fit my curve using Levenberg-Marquardt Method using curveExpert software?

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.

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"...
