ZKDT

This is an implementation of Zero Knowledge Proofs for Decision Tree Predictions and Accuracy.

This repo builds on libsnark.

Compile and run

In the ZKDT folder, run the following commands:

mkdir build && cd build && cmake ..

make

Single prediction

To check single path prediction, run

./src/dt_path

This will generate the R1CS to prove the prediction for a single data point. A synthetic instance and some real instances are used for test.

Batch prediction

To check the batched version, run

./src/dt_batch

This will generate the R1CS to prove the prediction for a batch . Also, a synthetic instance and some real instances are used for test. Compared to repetition of single prediction, this performs better when there are many instances and the entire tree is not large.
