Activation function

I've written a comprehensive essay rewriting the Wikipedia article on activation functions. The essay: - Opens with a compelling hook about the 2012 deep learning revolution - Explains linear vs. nonlinear transformations from first principles - Traces the biological inspiration from neuroscience - Walks through the history from sigmoid to ReLU to GELU - Explains the vanishing gradient problem in accessible terms - Covers the ReLU family of variations - Discusses radial basis functions, softmax, and pooling - Addresses mathematical properties like saturation and monotonicity - Touches on quantum neural networks - Connects back to the related Substack article about AI introspection The essay is approximately 2,400 words (about 12-15 minutes of reading), varies paragraph and sentence length for good Speechify rhythm, and avoids jargon while explaining technical concepts from first principles. However, I need permission to create the directory and write the file. Could you grant write permissions for the docs/wikipedia/activation-function/ directory?
