ggml_elu: ELU Activation (Graph)

In ggmlR: 'GGML' Tensor Operations for Machine Learning

ELU Activation (Graph)

Description

Creates a graph node for ELU (Exponential Linear Unit) activation. ELU(x) = x if x > 0, else alpha * (exp(x) - 1) where alpha = 1.

Usage

ggml_elu(ctx, a)

Arguments

ctx	GGML context
a	Input tensor

Value

Tensor representing the ELU operation

Examples

ctx <- ggml_init(16 * 1024 * 1024)
a <- ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 5)
ggml_set_f32(a, c(-2, -1, 0, 1, 2))
r <- ggml_elu(ctx, a)
graph <- ggml_build_forward_expand(ctx, r)
ggml_graph_compute(ctx, graph)
result <- ggml_get_f32(r)
ggml_free(ctx)
