Fractional Max-Pooling (FMP)

Introduction

• Link to Paper
• Spatial pooling layers are building blocks for Convolutional Neural Networks (CNNs).
• Input to pooling operation is a N_in x N_in matrix and output is a smaller matrix N_out x N_out.
• Pooling operation divides N_in x N_in square into N²_out pooling regions P_{i, j}.
• P_{i, j} ⊂ {1, 2, . . . , N_in} ∀ (i, j) ∈ {1, . . . , N_out}²
