Cart++

Cart++ is a C++ implementation of CART that contains:

• Fairness criteria
• Node-based losses
• Tree-based losses

The library is header-only (and heavily relies on C++20 templates and concepts), so just include the appropriate files when compiling.

Python binding

The module pycart is a Python binding using Cart++. The binding is written using Cython.

R binding

Will come at some point

Debug build and sanitizers

By default, this project assumes compiling with clang but supports gcc as well. To build pycart with sanitizers, add -fsanitize=address at compile-time. To be able to then use the module, prefix the python3 <file.py> with:

LD_PRELOAD="$(clang -print-file-name=libasan.so) $(clang -print-file-name=libasan.so)"

To have ASAN's logs in some log file, use option ASAN_OPTIONS="log_path=<path>"

For instance:

make pycart.so
LD_PRELOAD="$(clang -print-file-name=libasan.so) $(clang -print-file-name=libasan.so)" ASAN_OPTIONS="log_path=asan_log.txt" python3 test_cpp.py
file asan_log.txt
