* Fix index out-of-range exception generated by BaggingHelper on small datasets. Prior to this change, the line "score_t threshold = tmp_gradients[top_k - 1];" would generate an exception, since tmp_gradients would be empty when the cnt input value to the function is zero. * Update goss.hpp * Update goss.hpp * Add API method LGBM_BoosterPredictForMats which runs prediction on a data set given as of array of pointers to rows (as opposed to existing method LGBM_BoosterPredictForMat which requires data given as contiguous array) * Fix incorrect upstream merge * Add link to LightGBM.NET * Fix indenting to 2 spaces * Dummy edit to trigger CI * Dummy edit to trigger CI * remove duplicate functions from merge * Fix parsing of non-finite values. Current implementation silently returns zero when input string is "inf", "-inf", or "nan" when compiled with VS2017, so instead just explicitly check for these values and fail if there is no match. No attempt to optimise string allocations in this implementation since it is usually rarely invoked. * Dummy commit to trigger CI * Also handle -nan in double parsing method * Update include/LightGBM/utils/common.h Remove trailing whitespace to pass linting tests Co-authored-by:

Note that trees without linear models at the leaf always handle num_leaves = 1 as a special case and directly output the leaf value. Linear trees were missing this special case handling, and hence would have the following issues: * Calling Tree::Predict or Tree::PredictByMap would cause an access violation exception attempting to access the first value of the empty split_feature_ array in GetLeaf. * PredictionFunLinear would either cause an access violation or go into an infinite loop when attempting to do the equivalent of GetLeaf. Note also that PredictionFun does not need the same changes as PredictionFunLinear, since both are only called by Tree::AddPredictionToScore, which has a special case for (!is_linear_ && num_leaves_ <= 1) that precludes calling PredictionFun.
