Machine Learning Inference on Raspberry Pico 2040 via Edge Impulse

Cool that you created an AI example so fast after the release of this board.

[@Hardwareai]

Could have done even faster :) It's just I'm doing TinyML series tutorials at the same time

[@tiriotis]

Hi ,have you tried keyword detection with the pico using edge impulse if yes could you tell me what was dsp time?

[@Hardwareai]

I have not - while overall I liked Pico, I feel that upcoming Arduino board with Pi 2040 will be much more suitable for voice applications (it has built-in mic).

A quick note on the use of word "retarded" - it's a meme from r/WallStreetBets subreddit on Reddit, that's a normal way of address there. I used it here to describe my level of animation skill, that is very visible in the intro. Leaving this here to avoid anyone thinking "Hey, you just made fun of XXX!!111". If anything, I made fun of myself :)

Great intro IMHO :D

[@JeromeDemers]

I just watch the "Wio Terminal TinyML Course #1 Intro " and the rock paper scissor works way better with the proper training. In this video it's not really great. I imagine you deploy this system in a product but 2 year later the sensor if discontinued and you replace with new sensor, how would you convert the old training data to work with new sensor. You train a model to convert old model? :-)

[@Hardwareai]

Well, I use that model just to demonstrate how to run Edge Impulse C++ library on Pico - this is why the video is called Machine Learning Inference on Raspberry Pi Pico 2040 and not "Rock Paper Scissors Detector on Raspberry Pi Pico 2040" :) In general, model needs to be retrained for new hardware - it is inevitable unfortunately when working with sensor data.

printf can take more arguments. So you can do printf("%f, %f, %f ", result1, result2, result3); just make sure the arguments are in the right order. I'm not sure why you call the pico "pica" or arduino "arduina".

[@Hardwareai]

>>>printf can take more arguments yes, I'm aware of that, thanks >>>I'm not sure why you call the pico "pica" or arduino "arduina". Just a wacky Russian accent :)

[@nextlifeonearth]

@@Hardwareai ah, I couldn't think of of an accent doing that. Weird things; those accents sometimes. Thanks for what you add to the diy community by the way and thanks for responding. I can be a bit blunt in my comments as I read them back. Comes with being Dutch I guess.

[@Hardwareai]

Hahah, no worries, it's true, my English pronunciation could use some work - in this video it's mostly fine, but I had the worst blunder when making this video kzbin.info/www/bejne/qWHPiGZ-oMirY80 --- basically I pronounced Xavier as "ksa-vier", when it is actually "egza-vier"... I only found out the right pronunciation when half way done through editing, so I had to re-take the video xD

[@nextlifeonearth]

@@Hardwareai Ksa-vier isn't that wrong though. It's partially preference, since it is a word/name from another language where it is pronounced like that.
