Hello people

pemcilwarrior12•5/12/24, 11:05 AM

I hope you are doing well , I m working on a machine learning project and I just plotted the confusion matrix

Can someone tell me if my model is overfitting or not ?

youcef_ali•5/12/24, 12:36 PM

hi, we talked about the mqtt service provider such aws, azzure, if we pass the discution to the next level how you are storing data received from your clients, how you manage the reception how you store data using which tool, and what data dabase you are using sql, NoSQl ?

Am not an expert but I have quite a good knowledge on EMC EMI and can provide resources. What do you need to do

i trying to design a electromagnetic flowmeter , so in that i want to get rid of all the disturbances( voltage noise ) in the signal

Ppemcilwarrior12 Can someone tell me if my model is overfitting or not ?

wafa_ath•5/12/24, 1:19 PM

the model performs well for some classes but doesn't with others and that is a sign of overfitting

What are the classes that have overfitting if you can help ?

'e' 'd' 'm' 'n' 'o' 'p' 'q' 'r's' 't' 'u' 'v' 'w' 'x' 'y' 'z' 'you' 'bad 'fine' 'hungry' 'sorry' 'thankyou' 'deaf' 'me' 'please' 'goodbye', 'no' , the diagonal values are relatively low

pemcilwarrior12•5/12/24, 1:37 PM

But these have a value of 98% , how they can be overfitted ?

the diagonal values (representing correct classifications) are relatively low compared to the off-diagonal values (misclassifications). This suggests that the model struggles to accurately classify instances belonging to these classes.

Quiz time

Camila_99$$•5/12/24, 10:08 PM

Hiii Aymen

Camila_99$$•5/12/24, 10:09 PM

Humm wait a minute

aymen ammari•5/12/24, 10:09 PM

You have all the time

Camila_99$$•5/12/24, 10:16 PM

Vout = Vin * (R2 / (R1 + R2))

Camila_99$$•5/12/24, 10:16 PM

Am I correct

Camila_99$$•5/12/24, 10:17 PM

R1 is the resistance of the first resistor

aymen ammari•5/12/24, 10:17 PM

Well you can say Rout / Rin to Disperse between resistors

Camila_99$$•5/12/24, 10:17 PM

R2 for the second resistor

aymen ammari•5/12/24, 10:17 PM

But your good, go on...

Camila_99$$•5/12/24, 10:28 PM

Soo
Vout = 0.6V * (1.4 kΩ / (1 kΩ + 1.4 kΩ)) = 0.6V * (1.4 kΩ / 2.4 kΩ) = 0.35V

Camila_99$$•5/12/24, 10:29 PM

1.4 kΩ = Combined resistance

Aaymen ammari Quiz time ✨✨✨

Camila_99$$•5/12/24, 10:33 PM

0,35 V ?

CCamila_99$$0,35 V ?😁

aymen ammari•5/12/24, 10:37 PM

Womp womp

Camila_99$$•5/12/24, 10:45 PM

Is the result incorrect !!

Camila_99$$•5/12/24, 10:45 PM

I don’t think so

aymen ammari•5/12/24, 10:45 PM

Let me give you a hint

Camila_99$$•5/12/24, 10:45 PM

Ok go

aymen ammari•5/12/24, 10:47 PM

So we have 2 amplifiers.. With 2 different montages

aymen ammari•5/12/24, 10:47 PM

And V out from the first amplifier will be V in for the second one

Aaymen ammari So we have 2 amplifiers.. With 2 different montages

aymen ammari•5/12/24, 10:50 PM

This means that we will use 2 different laws

Camila_99$$•5/12/24, 10:58 PM

0,23 V ?

aymen ammari•5/12/24, 11:01 PM

aymen ammari•5/12/24, 11:01 PM

This is the first one

aymen ammari•5/12/24, 11:03 PM

aymen ammari•5/12/24, 11:03 PM

And this is the second one
