Change Log

All notable changes to this project will be documented in this file. This change log follows the conventions of keepachangelog.com.

[1.4.0 SNAPSHOT]

Added

• optimization package with various optimization methods
• NegativeBinomial distribution
• bootstrap datasets

Changed

• [breaking] classification and regression refactored
• [breaking] kernel-density moved to kernel namespace

[1.3.0 SNAPSHOT]

Added

• make-vector returns vector for given number of dimensions and optional sequence.
• vectors implements now IPersistentVector to work with vector?
• core.matrix protocols for vectors
• math functions can operate on vectors now (like [[sin]] etc.)
• new functions for vectors clamp, zero-count, nonzero-count, as-vec
• classification bindings for SMILE, ~~XGBoost~~ and LIBLINEAR
• expm1 function
• monotone interpolation
• various extent stats funcions
• haversine and haversine-dist (distance)
• predicates nan?, inf?, valid-double?, invalid-double?, between?
• calculate intervals for set of values co-intervals (same as R's function). Also group-by-intervals.
• various kernel-density methods and kernel-density-ci for kernel density with confidence interval
• various effect size functions
• binary measures like fn, tp, etc... (around 30 statistics)
• multivariate normal distribution added
• gaussian processes reimplemented
• kernels consolidated in one namespace

Changed

• use fmap instead of applyf (now deprecated)
• outliers are samples which are outside inner fence instead of outer fence
• Vectors are associative now
• [breaking] kernel-density is now multimethod
• [breaking] histogram :bins contain starting point and sample counts only

Removed

• rbf-obj converter
• rbf and mercer namespaces (use fastmath.kernel instead)

[1.2.0]

Added

• Various grid operations
• hashCode for vectors

Changed

• Breaking: sequence generator creatators return lazy sequence now (instead of function returning sequence)

[1.1.4]

Added

• lcm - least common multiplier
• Vec types implement Reversible Indexed ILookup
• negative values for some constants (PI, E etc.)

Fixed

• GAMMA constant name clash

Changed

• stats-map returns list of outliers rather than number of outliers

Removed

• :bessel vector field removed (hard to limit input range)

[1.1.3]

Added

• sample can now return pairs of [x,(f x)].

[1.1.2]

Added

• estimators for number of bins in histogram
• kernel-density function

[1.1.1]

Changed

• histogram data enhanced

[1.1.0]

Added

• fastmath.clustering namespace

Changed

• removed k-means from fastmath.stats

[1.0.3]

Fixed

• norm when domain is a point, returns range start when value is less or equal domain, range end otherwise
• small fix in one field

[1.0.2]

Added

• curl for 2d vector fields

[1.0.1]

Added

• :default (:jdk) rng is added

Fixed

[1.0.0]

Added

• easings namespace
• sample function
• extent stat ([min,max] pair)
• histgram
• vector field functions moved from clojure2d, api changed

Changed

• interpolator have shorter names now (without -interpolator suffix)
• rbf functions are moved to separate namespace
• changed parameters order in interpolators (xs and ys are last)
• next-float-up -> next-double
• next-float-down -> prev-double

[0.1.1]

Added

• BesselJ
• all Gamma function variants (regularized, etc)
• regularized Beta
• log1p
• estimation-strategy can be passed to any function calculating quantiles/percentiles
• ->seq can accept number of samples now
• low-exp, high-exp to find lower/greater exponent for given base and number

Changed

• stats-map doesn't contain select keys option anymore

[0.1.0]

Initial version created from Clojure2d library.
