Knet (pronounced "kay-net"), which stands for "Koç University deep learning framework," is an open-source library written in Julia for defining and training deep learning models. It is specifically designed to be efficient and flexible by utilizing dynamic computation graphs for building complex neural network architectures. Knet allows for automatic differentiation, which simplifies the process of computing gradients for optimization algorithms used in training deep learning models.The choice of Julia language enables Knet to leverage high performance computing while maintaining ease of use and readability. The library supports typical layers, loss functions, and optimizers used in deep learning, making it suitable for both beginners and experienced researchers in the field. Detailed documentation and examples are available on its GitHub repository [Knet on GitHub](https://github.com/denizyuret/Knet.jl), making it accessible for users to start experimenting with and deploying various machine learning models.
