Can anyone help me understand the implementation of nn.Bilinear
As per the documentation, this function implements y = x₁^T * A * x₂
taking x1 = (100,20) , x2 = (100,30') , assuming output_features = 50. The matrix A has dimensions of [50,20,30].
I am finding it difficult how these matrices are multiplied to get the output = [100,50]

Based on the size of x₁,x₂ and A matrix, the multiplication seems incompatible as per y = x₁^T * A * x₂ . What am I missing here?
