Accord Framework HiddenMarkovClassifier(TDistribution, TObservation) API


When I upgrade to Accord Framework 3.2.0 and run software I get 2 'obsolete' errors:

Warning 1 'HiddenMarkovClassifier'<'MultivariateNormalDistribution'>'' is obsolete: 'Please use HiddenMarkovClassifier'<'TDistribution, TObservation'>' instead.'

Warning 14 'BaumWelchLearning'<'MultivariateNormalDistribution'>' is obsolete: 'Please use BaumWelchLearning'<'TDistribution, TObservation'>' instead.'

There is no apparent API for the BaumWelchLearning'<'TDistribution, TObservation'>'. When I go to the new API for HiddenMarkovClassifier'<'TDistribution'>' and the relatively minor changes reflected on that documentation it does not fix the 2 issues above.

Any suggestions?

The "using" keyword makes a member of an inherited class visible, and resolvable, in the scope of its subclass. So, to make the privately-inherited member available to B's subclasses:

class A {


    void foo() {}

class B : private A {


    using A::foo;

class C : public B {

    void bar()

An item of type undefined (and it is a type) has no length property - only items of type string and array do. Therefore, as @redneb notes, extend your condition to check for a non-falsy value before checking length.

if (myVar && myVar.length) { ... }
