AttentionLayer

This package implements the attention mechanism as a Lux layer. It can then be used for closure modeling.

Install

using Pkg
Pkg.add(url="git@github.com:DEEPDIP-project/AttentionLayer.jl.git")

Usage

You are probably interested in using the attentioncnn model, which is a built-in cnn that uses the attention mechanism. Here is an example of how to use it:

• first you have to define the parameters of the model

    T = Float32 # the type of the data
    N = 16 # size of the input
    D = 2 # number of channels
    rng = Xoshiro(123) # random number generator
    r = [2, 2] # radii of the attention mechanism
    c = [4, 2] # number of features of the intermediate layers
    σ = [tanh, identity] # activation functions
    b = [true, false] # use bias
    emb_sizes = [8, 8] # size of the embeddings
    patch_sizes = [8, 5] # size of the patches in which the attention mechanism is applied
    n_heads = [2, 2] # number of heads of the attention mechanism
    use_attention = [true, true] # use the attention at this layer
    sum_attention = [false, false] # use attention in sum mode instead of concat mode (BUG)

• then you can call the model

    closure, θ, st = attentioncnn(
        T = T,
        N = N,
        D = D,
        data_ch = D,
        radii = r,
        channels = c,
        activations = σ,
        use_bias = b,
        use_attention = use_attention,
        emb_sizes = emb_sizes,
        patch_sizes = patch_sizes,
        n_heads = n_heads,
        sum_attention = sum_attention,
        rng = rng,
        use_cuda = false,
    )
