Кодируем как по проводу: как представить категориальные данные для нейросети
Что общего между нейросетью и радиопередатчиком? В этой статье я рассматриваю кодирование категориальных признаков как процесс передачи информации через сигнальные каналы — с гармониками, фазами, QAM-созвездиями и функциями активации, превращающими данные в управляемые сигналы.

Tecnicamente, il Wi-Fi 7 (ratificato nel 2022) è il nome “semplice” dello standard 802.11be, come Wi-Fi 6 lo è per l’802.11ax, mentre Wi-Fi 5 è lo standard 802.11ac.
Come tutte le precedenti norme Wi-Fi, il Wi-Fi 7 sarà retrocompatibile. I tuoi dispositivi esistenti saranno in grado di connettersi a un trasmettitore Wi-Fi 7 (router o punto di accesso),
Very cool work from @DutraCGI , love trying to follow along 😅 🤓

#random modulation procedure starts with two #stochastic baseband signals, { x_{c}(t)} and { x_{s}(t)}, whose frequency spectrum is non-zero only for {f\in [-B/2,B/2]}. It applies #qam to combine these with a carrier frequency { f_{0}} (with { f_{0}>B/2}) to form signal {x(t)}

Analog video removal removes #cabletheft as analog were transmitted unencrypted. signals are compressed to MPEG-2/4 to combine multiple streams to a #QAM most efficient use of spectrum which cable set top box receives, demods de-encrypts, displays as a virtual channel #
