 ## TODO
 
 ### Short term
 
 - Implement autotuning of `GaussianMixtureClusterer` using  `BIC` or `AIC`
-- Add Silhouette method to check cluster validity
+- <del>Add Silhouette method to check cluster validity</del>
 - Implement PAM and/or variants for kmedoids
 
 ### Mid/Long term
 
 - Add RNN support and improve convolutional layers speed
 - Reinforcement learning (Markov decision processes)
 - Standardize data sampling in training
-- Convert to GPU
+- Add GPU
