But what exactly do the output values mean? Say the inputs are sensor values, what do the outputs mean in terms of the sensor values?

HEY EVERYONE I DO THIS AS A PASTIME ACTIVITY INSTEAD OF PASSIVE ENTERTAINMENT!!!!!! AM I NOT A GOOD BOY?????!!!!!!!!!!

in the second layer you used output_Layer1 and its new matrix with 3*3 in dot method with weights wich is matrix 4*3 doesnt accept it . but in your video everything was okay and i cofused

Are weights in neural network same as weights in linear regression?

That's a great way to visualize matrix multiplication!

just for sake of comment but frankly speaking, I am speechless for what you are doing… I really Loved your videos. sometimes I didn't even hit like because hurrying for the next video but I had to go back and like them all.
this is by far the best video tutorial I have ever came across on deep learning. this by itself is an advanced university-level lecture. sorry for calling it Turorial. My deepest and humble respect! stay cool and safe 🙂

Thought I knew what batch size was about…. I was completely wrong….I need to think like a neuron! Thanks again Sentdex for yet another great video!

Awesome series! As someone not very familiar with OOP… what is the advantage of using Classes instead of functions for the operations of the layer?

Thank you! You defently Rock! your videos a nutral gift, for many people!

Is there any way to get the next tutorials??
I'm leaning all this ay my uni and you just summarized a month worth of class into 5 videos!

What do you use to create these neat illustrations and animations?

Thank you very much sentdex for such a superb explanation..i never found such a great quality of explanation.

if you transposed inputs instead of weights it woud have been the same right?

Hi there. Just a small question: In this case, the "n_imputs" is created randomly and he is not taking the inputs he typed in the beginning, right?

at 9: 29, in Engineering maths we do a great deal manual matrix product calculations, your explanations refreshes my mind Daniel

Very intersting! I've never used "class" before

you're that great you should run for president it's not too late.. thanks for the video 🙂

Anyone else getting a “Layer_Dense() takes no arguments” error?

• sentdex

Each input can be from a neuron right? So for example when the list was a vector, those four elements values could be seen as an individual neuron from a prior layer. My question is, when you added the batch, does that mean that if we were to visualize this the input layer would have 12 neurons then?

I will have to re-watch this few times. Anyway good job!

Why do we prefer weights.T over inputs.T ?
