* Fix Barlow Twins loss gradient * Update reference test accuracy after fix * Round the empirical cross-correlation matrix Just a tiny modification that allows the values to actually reach 255 (perfect white).

* wip: loss goes down when training without a dnn_trainer if I use a dnn_trainer, it segfaults (also with bigger batch sizes...) * remove commented code * fix gradient computation (hopefully) * fix loss computation * fix crash in input_rgb_image_pair::to_tensor * fix alias tensor offset * refactor loss and input layers and complete the example * add more data augmentation * add documentation * add documentation * small fix in the gradient computation and reuse terms * fix warning in comment * use tensor_tools instead of matrix to compute the gradients * complete the example program * add support for mult-gpu * Update dlib/dnn/input_abstract.h * Update dlib/dnn/input_abstract.h * Update dlib/dnn/loss_abstract.h * Update examples/dnn_self_supervised_learning_ex.cpp * Update examples/dnn_self_supervised_learning_ex.cpp * Update examples/dnn_self_supervised_learning_ex.cpp * Update examples/dnn_self_supervised_learning_ex.cpp * [TYPE_SAFE_UNION] upgrade (#2443) * [TYPE_SAFE_UNION] upgrade * MSVC doesn't like keyword not * MSVC doesn't like keyword and * added tests for emplate(), copy semantics, move semantics, swap, overloaded and apply_to_contents with non void return types * - didn't need is_void anymore - added result_of_t - didn't really need ostream_helper or istream_helper - split apply_to_contents into apply_to_contents (return void) and visit (return anything so long as visitor is publicly accessible) * - updated abstract file * - added get_type_t - removed deserialize_helper dupplicate - don't use std::decay_t, that's c++14 * - removed white spaces - don't need a return-statement when calling apply_to_contents_impl() - use unchecked_get() whenever possible to minimise explicit use of pointer casting. lets keep that to a minimum * - added type_safe_union_size - added type_safe_union_size_v if C++14 is available - added tests for above * - test type_safe_union_size_v * testing nested unions with visitors. * re-added comment * added index() in abstract file * - refactored reset() to clear() - added comment about clear() in abstract file - in deserialize(), only reset the object if necessary * - removed unecessary comment about exceptions - removed unecessary // ------------- - struct is_valid is not mentioned in abstract. Instead rather requiring T to be a valid type, it is ensured! - get_type and get_type_t are private. Client code shouldn't need this. - shuffled some functions around - type_safe_union_size and type_safe_union_size_v are removed. not needed - reset() -> clear() - bug fix in deserialize() index counts from 1, not 0 - improved the abstract file * refactored index() to get_current_type_id() as per suggestion * maybe slightly improved docs * - HURRAY, don't need std::result_of or std::invoke_result for visit() to work. Just privately define your own type trait, in this case called return_type and return_type_t. it works! - apply_to_contents() now always calls visit() * example with private visitor using friendship with non-void return types. * Fix up contracts It can't be a post condition that T is a valid type, since the choice of T is up to the caller, it's not something these functions decide. Making it a precondition. * Update dlib/type_safe_union/type_safe_union_kernel_abstract.h * Update dlib/type_safe_union/type_safe_union_kernel_abstract.h * Update dlib/type_safe_union/type_safe_union_kernel_abstract.h * - added more tests for copy constructors/assignments, move constructors/assignments, and converting constructors/assignments - helper_copy -> helper_forward - added validate_type<T> in a couple of places * - helper_move only takes non-const lvalue references. So we are not using std::move with universal references ! - use enable_if<is_valid<T>> in favor of validate_type<T>() * - use enable_if<is_valid<T>> in favor of validate_type<T>() * - added is_valid_check<>. This wraps enable_if<is_valid<T>,bool> and makes use of SFINAE more robust Co-authored-by:
