2D Convolution For running convolution we need 2 things: input matrix with shape (Batch, Channels, Height, Width) and kernels of our convolution with shape (Out Channels, Input Channels, Height, Width), for each input channel we use different kernel. Iteratively we get part of the input matrix with the size of kernel and…

Most of the things you should to know about React-Native in 2020 Best Practices Platform-specific styles https://reactnative.dev/docs/platform-specific-code#platform-module Platform-specific modules For example, say you have the following files in your project: BigButton.ios.js BigButton.android.js You can then require the component as follows: import BigButton from './BigButton'; Use React-Redux and for more hard cases React-Saga
