Pierre-Edouard Portier 96e55f2c72 experiment with associating mca clusters with nakr errors 2023-03-27 12:04:40 +02:00
Pierre-Edouard Portier 5689bf6fef Nystroem approximation is now correct (and simplified). 2023-03-19 18:48:47 +01:00
Pierre-Edouard Portier 3c83c256b5 progress on nystroem approximation implementation ; there is still a problem: for a small sample size the result of krr should be the same as the one of nystroem approx krr where the number of landmarks is equal to the number of training points. For now, it isn't. 2023-03-13 13:01:40 +01:00
