Hi @AdilDarvesh-w5f, Thank you for your support! 😊 If you're interested in more content like this, feel free to check out my other tutorials in this playlist: ua-cam.com/video/7Es1ZWiMq0Y/v-deo.html&pp=gAQBiAQB. I hope you find them helpful!
Hi @patelpavan5479, yes, you can assign weights lower than 1 in PINNs. The weights, like 4 and 2 in my video, are just random numbers used to balance the loss terms (reasons explained in the video). The weights control the balance between different loss terms, so smaller weights reduce the importance of a term. Just ensure the weights don’t downplay key components too much. It's all about balancing based on your specific problem, so feel free to experiment! Let me know if you have any more questions, and feel free to join our Telegram group for more updates and discussions!
Hi @patelpavan5479 Thanks for your suggestion! I'm planning to cover more topics on PDEs soon. Neumann boundary conditions will definitely be included! Stay tuned for upcoming videos.
Sir how can i satisfy exact initial condition like for my problem I have initial condition T(0) =0 ,T(1)= 1 but when I am predicting values at these conditions, I am not getting exact value so how can i modify my model.
Hi @ramsaran_india, Thank you for your question! I assume your domain is from 0 to 1, and you're trying to satisfy the initial and boundary conditions T(0)=0 and T(1)=1. If you're not getting the exact values at these points, one approach to address this is by adjusting the loss function, as I demonstrated in the tutorial. Specifically, you can give more weight to the loss terms that account for the initial and boundary conditions. This ensures that the model focuses more on matching these conditions during training. I encourage you to revisit the part of the video where I explain the multi-weighted loss function, as it can help with situations like this. Let me know if you have any more questions!

Good understanding for me❤😊

Can this method be similar for non linear ode's
Excellent
Much appreciated for your commitment
Hi @EmmanuelOseiTutu-n7v, thank you so much for your kind words!
Why multiply 4 and 2 in loss can we multiply less values like 0.1,0.2 , what is beneficial less or more weight value?

@@elastropy thanks and make video on pde also.
With neumman type boundry conditions

@@elastropy Sure!!
