Re: [Idnet] IETF99 for applying AI/ML into network management: Follow-up

Dear Simone,

Sheng had sent a page of PPT which was mostly focused in the meeting. You can find it in: https://www.ietf.org/mail-archive/web/idnet/current/msg00113.html

BTW, according to the discussion in mailing list, Pedro and I made a little modification and you can find it in the attachment: https://www.ietf.org/mail-archive/web/idnet/current/msg00104.html

It is welcome to point out the drawbacks and improve it.

Yansen
