CHANGES IN FNN VERSION 1.1.3
o Fix memory leakage for mutual information calculation
CHANGES IN FNN VERSION 1.1.2
o Remove C++ uses of 'register' keyword.
o Register native routines.
CHANGES IN FNN VERSION 1.1
o mutinfo function for mutual information is added.
o Rarely used VR algorithm is removed.
CHANGES IN FNN VERSION 1.0
o get.knn works with an integer data.frame now.
o Fix knn.reg scaling issue when use.all is TRUE.
CHANGES IN FNN VERSION 0.6-4
o Add optimal weighted knn classifier.
CHANGES IN FNN VERSION 0.6-3
o Remove links to some cross-refence packages which may not-yet-installed.
o Add suggested packages
o Add the brute-force (linear scan) method.
CHANGES IN FNN VERSION 0.6-2
o Add 1 - inner product distance measure.
o Fix memory allocation bug for get_KNNX_kd
CHANGES IN FNN VERSION 0.6-0
o Fixed complier complaints on 64-sun and soloris-sparc platforms.
CHANGES IN FNN VERSION 0.5-9
o Try to fix complier complaints on 64-sun and soloris-sparc platforms.
CHANGES IN FNN VERSION 0.5-8
NEW FEATURES
o memory deallocation for cover tree is added. No more memory leaks.
o memory efficient. New copies of data are no longer created in C for kd tree
and cover tree as in VR.
o new_leaf initial values changed from 0. to 0.0f in order to solve SUN Studio complaints.
BUG FIXED
o sqrt was extra for distance for knn and knn.cv
CHANGES IN FNN VERSION 0.4
NEW FEATURES
o added knn crossentropy and entropy estimators.
o added cover-tree and VR algorithms for KL.divergence and KL.dist.
o Self-matching:
get.knnx: self-match for cover_tree and kd_tree is turned on.
get.knn: self-match is turned off for "VR".
In summary self-match is allowed for get.knnx but not for get.knn.
o knn.reg: remove "y" from result and rename R_square to R2Pred.
change class from "KNNReg" to "knnReg" or "knnRegCV" depending to if test is supplied.
o KNN_ANN.cpp: remove or change variable-size array to "new" ponter to comply with ISO C++.
o cover_tree: remove zero padding point dimension.
BUG FIXES
o get.knnx: fix dimension for the nn.index and nn.dist ( change n to m).
CHANGES IN FNN VERSION 0.3
NEW FEATURES
o Index label is added for cover tree
o knn.index, get.knn and get.knnx include cover tree algorithm now.
CHANGES IN FNN VERSION 0.2
NEW FEATURES
o NAMESPACE is used.
