What this calculator is doing

This tool computes the computational cost of Conv2D layers in Convolutional Neural Networks. MACs (Multiply-Accumulate Operations) Each output element in a Conv2D operation requires a number of MACs based on: \[ \text{MACs} = H_{\text{out}} \cdot W_{\text{out}} \cdot C_{\text{in}} \cdot K_H \cdot K_W \cdot C_{\text{out}} \cdot \text{Batch} \cdot \text{Layers} \] Where:
- \(H_{\text{out}}, W_{\text{out}}\): Output height and width
- \(C_{\text{in}}\): Input channels
- \(K_H, K_W\): Kernel height and width
- \(C_{\text{out}}\): Number of filters
- Multiply by 2 to get FLOPs (1 MAC = 2 FLOPs)
This is a critical metric for optimizing model deployment on edge devices, GPUs, and TPUs.
