WebMar 1, 2024 · The PCA is parameter free whereas the tSNE has many parameters, some related to the problem specification (perplexity, early_exaggeration), others related to the gradient descent part of the algorithm. Indeed, in the theoretical part, we saw that PCA has a clear meaning once the number of axis has been set. However, we saw that σ σ appeared ... WebThe learning rate can be a critical parameter. It should be between 100 and 1000. If the cost function increases during initial optimization, the early exaggeration factor or the learning rate might be too high. If the cost function gets stuck in a bad local minimum increasing the learning rate helps sometimes. method : str (default: 'barnes_hut') dachshund puppies dallas texas https://rebolabs.com
