K Nearest Neighbors * Use the k-nearest neighbors algorithm to return the |k nearest neighbors of the provided features. These features are the result of a dimensionality reduction by PCA on some operating-system data related to processes and their intrusivity in some network. You'll have access to an EXAMPLES dictionary, mapping each process identifier |"pid_i" to a respective dictionary containing its associated features as well as a label representing whether the relevant process was intrusive to the network. A label of | 0 means that it wasn't intrusive, while a label of 1) means that it was intrusive. Below is an example portion of the EXAMPLES : "pid o": { "features": [3.968642003034218, 3.9553899901567955, 3.8067717105202794, "is intrusive": @, LP "pid 1": { "features": [3.905930716908446, 3.9843869514613046, 3.999386668299634, "is intrusive": @, iP "pid 500": { "features": [4.309361217767318, 4.287392829732823, 4.296809382863873, "is intrusive": 1, on
