[0.3.0]

Added

• ScaleOperations interface
• Field extends ScaleOperations
• Basic integration API
• Basic MPP distributions and samplers
• bindSymbolOrNull
• Blocking chains and Statistics
• Multiplatform integration
• Integration for any Field element
• Extended operations for ND4J fields
• Jupyter Notebook integration module (kmath-jupyter)
• @PerformancePitfall annotation to mark possibly slow API
• Unified architecture for Integration and Optimization using features.
• BigInt operation performance improvement and fixes by @zhelenskiy (Karatsuba added, 2 bugs are fixed #328)
• Integration between MST and Symja IExpr
• Complex power
• Separate methods for UInt, Int and Number powers. NaN safety.
• Tensorflow prototype
• ValueAndErrorField
• MST compilation to WASM: Enable MST compilation to WebAssembly #286
• Jafama integration: Integration with Jafama #176
• contentEquals with tolerance: Add function contentEquals for comparable types with absoluteTolerance parameter #364
• Compilation to TeX for MST: Create extensible TeX compilation engine for MST #254

Changed

• Exponential operations merged with hyperbolic functions
• Space is replaced by Group. Space is reserved for vector spaces.
• VectorSpace is now a vector space
• Buffer factories for primitives moved to MutableBuffer.Companion
• Rename NDStructure and NDAlgebra to StructureND and AlgebraND respectively
• Real -> Double
• DataSets are moved from functions to core
• Redesign advanced Chain API
• Redesign MST. Remove MstExpression.
• Move MST to core
• Separated benchmarks and examples
• Rewrite kmath-ejml without ejml-simple artifact, support sparse matrices
• Promote stability of kmath-ast and kmath-kotlingrad to EXPERIMENTAL.
• ColumnarData returns nullable column
• MST is made sealed interface
• Replace MST.Symbolic by Symbol, Symbol now implements MST
• Remove Any restriction on polynomials
• Add out variance to type parameters of StructureND and its implementations where possible
• Rename DifferentiableMstExpression to KotlingradExpression
• FeatureSet now accepts only Feature. It is possible to override keys and use interfaces.
• Use Symbol factory function instead of StringSymbol
• New discoverability pattern: <Type>.algebra.<nd/etc>
• Adjusted commons-math API for linear solvers to match conventions.
• Buffer algebra does not require size anymore
• Operations -> Ops
• Default Buffer and ND algebras are now Ops and lack neutral elements (0, 1) as well as algebra-level shapes.
• Tensor algebra takes read-only structures as input and inherits AlgebraND
• UnivariateDistribution renamed to Distribution1D
• Rework of histograms.
• UnivariateFunction -> Function1D, MultivariateFunction -> FunctionND

Deprecated

• Specialized DoubleBufferAlgebra

Removed

• Nearest in Domain. To be implemented in geometry package.
• Number multiplication and division in main Algebra chain
• contentEquals from Buffer. It moved to the companion.
• MSTExpression
• Expression algebra builders
• Complex and Quaternion no longer are elements.
• Second generic from DifferentiableExpression
• Algebra elements are completely removed. Use algebra contexts instead.

Fixed

• Ring inherits RingOperations, not GroupOperations
• Univariate histogram filling
