In this video we'll import the iris dataset and Train our Model!
We'll import the iris dataset as a CSV file, and then tweak the last column a bit.
Then we'll set up a Train/Test/Split and start to train the model using SKLearn and Pytorch.

Really love your series - I would really appreciate it if you can go through what the backpropation functions do: optimizer.zero_grad() loss.backward() optimizer.step()

Awesome tutorial, it's great to see that you are using sklearn for data partitioning, thanks for the tutorial! Keep up the good work👍

Hi John. Great video and really clear explanation. Just one question, is there a better way of classifying the flower types. It seems like doing it numerically with all types on the same scale is a bit strange and could lead to some confusion for less accurate models. For example, the machine might give a score of 1.1 because it is unsure whether a flower is Setosa (0.0) or Virginica (2.0). However, a score of 1.1 would lead us to conclude that it is most likely Versicolor. Is there a way to avoid this? I hope I'm being clear.

torch.FloatTensor(x) not converting x to torch tensor but creating a torch tensor x dimension!!! . Not sure if I am missing anything?

Sir, I have covered full playlist of kivy and it is really amazing, but when we make the kivy program we can only excess it on system which contains the compiler but what if I want to share it or want to convert it into apk can we do it. Please make one more amazing videos and solve this problem, I have already tried Google cllab but file get crashed again and again.

Thank you so much. However, I have a problem with my Colab; I am not able to visualize the epochs like you did around the timestamp 19 minutes and 30 seconds. How do I set up my Colab like that?

@kombatbakpen6820 3 месяца назад

I figured it out professor! thank you . Can you do a playlist list on computer vision with openCV?😇

hi guys i just started playing with neural networks and i have a little problem with this tutorial and no matter what i do my losses and epochs graph is stationary on one value. PLS help

@tobiasschulze-heinrichs3187 6 месяцев назад

Can you share your code? One thing I could think of is that you run the training itself multiple times - that is something you shouldn't do as the model already learned some weights and biases. You are basically overfitting the model. Run the whole notebook instead

For me this was because I had a type on class forward: ``` def forward(self, x): x = F.relu(self.fc1(x)) x = F.relu(self.fc2(x)) x = self.out(x) # remove the ReLU activation here return x```
