| functions (e.g., written in Python). To make data computation more easier and |
| faster (in native speed), the platform also provide some commonly used functions |
| written in Rust. We call them built-in functions. These functions can be |
| selectively compiled in the <em>built-in executor</em> with a "builtin" prefix in the |
| function names. Users can selectively invoke these build-in functions by their |
| names.</p> <p>Currently, we have these built-in functions:</p> <ul><li><code>builtin-echo</code>: Return the original input message.</li> <li><code>builtin-gbdt-train</code>: Use input data to train a GBDT model.</li> <li><code>builtin-gbdt-predict</code>: GBDT prediction with input model and input test data.</li> <li><code>bulitin-logistic-regression-train</code>: Use input data to train a LR model.</li> <li><code>builtin-logistic-regression-predict</code>: LR prediction with input model and input test data.</li> <li><code>builtin-private-join-and-compute</code>: Find intersection of muti-parties' input |
| data and compute sum of the common items.</li> <li><code>builtin-ordered-set-intersect</code>: Allow two parties to compute the |
| intersection of their ordered sets without revealing anything except for the |
| elements in the intersection. Users should calculate hash values of each item |
| and upload them as a sorted list.</li> <li><code>builtin-rsa-sign</code>: Signing data with RSA key.</li> <li><code>builtin-face-detection</code>: An implementation of Funnel-Structured cascade, |
| which is designed for real-time multi-view face detection.</li> <li><code>builtin-principal-components-analysis</code>: Example to calculate PCA.</li> <li><code>builtin-password-check</code>: Given a password, check whether it is in the |
| exposed password list.</li></ul> <p>The function arguments are in JSON format and can be serialized to a Rust struct |
| very easily. You can learn more about supported arguments in the implementation |
| of a specific built-in function.</p></div> <footer class="page-edit"><!----> <div class="last-updated"><span class="prefix">Last Updated:</span> <span class="time">12/18/2020, 7:00:24 PM</span></div></footer> <div class="page-nav"><p class="inner"><span class="prev"> |

| Apache Teaclave (incubating) is an effort undergoing incubation at The Apache |
| Software Foundation (ASF), sponsored by the Apache Incubator. |
| Incubation is required of all newly accepted projects until a further review |
| indicates that the infrastructure, communications, and decision making process |
| have stabilized in a manner consistent with other successful ASF projects. While |
| incubation status is not necessarily a reflection of the completeness or |
| stability of the code, it does indicate that the project has yet to be fully |
| endorsed by the ASF. |
