* Add softmax function for matrix type
* make softmax inherit from basic_op_m
* fix comment
* add test for matrix softmax
* remove include
* take inspiration from op_normalize
* use multiplication instead of division
* fix typo in documentation
This reverts commit 8b9d04390c.
Reverting this because the cmake pip pakage is still busted. I've been
getting messages from many people about how it's breaking their
systems/installs.
This dependency was explicitly removed two years ago because pip was
installing a broken cmake on some systems. I'm adding the dependency
back in the hope that the pip copy of cmake has been fixed on all
systems by this point.
* [SERIALIZATION] - vectorstream can now be used with vector<int8_t> and vector<uint8_t>
* [SERIALIZATION] - update proxy_serialize and proxy_deserialize to work with vector<int8_t> and vector<uint8_t>
* [SERIALIZATION] - updated vectorstream tests
* [SERIALIZATION] - updated serialize tests. check you can go to and from any of vector<char>, vector<int8_t> and vector<uint8_t>
* [SERIALIZATION] - updated matrix tests. check you can go to and from any of vector<char>, vector<int8_t> and vector<uint8_t>
* [SERIALIZATION] - updated dnn tests. check you can go to and from any of vector<char>, vector<int8_t> and vector<uint8_t>
* [SERIALIZATION] improved and possibly safer
* [SERIALIZATION] use placement new. best of all worlds i think. we have least object overhead. but code looks a tad uglier. oh well, user doesn't have to care
* [SERIALIZATION] i hope this is easier on the eyes.

* [FFT] added fft, ifft, fft_inplace and ifft_inplace overloads for std::vector
* [FFT] - static_assert T is a floating point type. There are static asserts in mkl_fft and kiss_fft, but it doesn't hurt adding them in the matrix API too so users get helpful warnings higher up in the API.
* [FFT] - added documentation for std::vector overloads in matrix_fft_abstract.h file

* Early termination for find_{min,max}_global
This patch adds a callback to allow the user to request cancellation of a
search using find_{min,max}_global. This enables users to cancel
searches when they are no-longer relevent, or when the user has some
special knowledge of the solution that they can use the stop the search
early.
closes #2250
* Moved default stopping condition into find_max_global.h since that's the code it relates to and did some minor cleanup.

This also makes it so the num and max_runtime arguments can now appear
in any order.
This does include a minor backwards compatibility break. Which is
someone passing in initial function evaluations by directly supplying an
initializer list like {function_evaluation({1.1, 0.9}, rosen({1.1, 0.9}))} may have
to do std::vector<function_evaluation>{function_evaluation({1.1, 0.9},
rosen({1.1, 0.9}))} instead or make it a variable. This is due to C++
not supporting direct use of initializer lists with variadic templates in this
context. But in any case, I doubt many users do this and it is not hard
for those that do to update as described above.
* fix find_min_global finding wrong answers
Previously, find_min_global would produce wrong output when passed
a collection of initial evaluations because the solver expected the
y-values to be multiplied by -1. This fix does that when minimizing.
closes#2283
* fixed tabbing

* [FFT] added kissfft wrappers, moved kiss and mkl wrappers into separate files, call the right functions in matrix_fft.h

that cuda is available even though it knows it didn't find cublas, which
is part of the standard cuda install. So we need to add a check to see
if cmake *really for realz* found cuda.
* Added exponential distribution
* tab problem removed?
* forgot std::
* Also added Weibull distribution. Very useful indeed.
* Simple Weibull distribution unit test
* don't forget std::
* sorry, typo
* [RAND] - seed the random number generators for consistency and no nasty surprises
- added parameter for tolerance
- added unit test for exponential distribution
* [RAND] print the spinner more often
* [RAND] up the tolerance for kurtosis a bit
* [RAND] refactored parameters to reflect documentation on wikipedia.
* [RAND] added documentation to _abstract
* [RAND] i switched the order of the arguments to get_random_weibull and didn't update the unit tests. oops

* fix typos
* add cifar-10
* open files in binary mode
* print messages with file name only, like mnist loader
* some fixes
* add mnist.cpp to CMakeLists.txt
* fix test index
* do not use iterator in cast
* add cifar.cpp to all
* Add Davis' suggestions
* no need to use namespace std and clean up empty lines
* [SERIALIZATION] fixed bug when (de)serializing vector<complex<float>>. DLIB_DEFINE... macro uses __out and __in variables names for ostream and istream objects respectively to avoid member variable name conflicts.
* Refactoring objects in DLIB_DEFINE_DEFAULT_SERIALIZATION to avoid name conflicts with user types
* Refactoring objects in DLIB_DEFINE_DEFAULT_SERIALIZATION to avoid name conflicts with user types
* removed tabs
* removed more tabs
