WebJul 18, 2024 · The Rtsne function has three main hyperparameters: initial_dims (default 50) providing that pca=TRUE. perplexity (default 30) max_iter (default 1000) Here, we will go through these hyperparameters and explain what they mean. Obviously, their default values might not work well for arbitrary data. WebNov 27, 2024 · I would like to have this information to properly set the max_iter parameter of the GridSearch. Describe your proposed solution.
