Using the Machine Learning Libraries in SAP HANA Cloud
Chief partner engineer, Philip MUGGLESTONE just updated his SAP HANA Cloud playlist on the SAP HANA Academy YouTube channel with a new video covering the machine learning libraries native to SAP HANA Cloud
- PAL – Predictive Analysis Library
- APL – Automated Predictive Library
In this blog, you will find the video embedded with some additional information and resources.
You can watch the video tutorial in just under 12 minutes. What you get back is
- Understand the prerequisites
- Getting started with PAL
- Getting started with APL
For those less familiar with the machine learning libraries: PAL is a native (built-in) application function library (AFL) for SAP HANA. APL bundles the algorithms of SAP Predictive Analytics which goes back to KXEN InfiniteInsight, acquired by SAP in 2013. Both AFLs can be used for linear regression and other common algorithms.
To continue your machine learning journey on SAP HANA Cloud, the following blog post is highly recommended:
As with the SAP HANA platform edition (on-premises), we need to enable the script server process. Currently, this currently requires a service request on component HAN-CLS-HC (as documented). In addition, we need to create an SAP HANA Cloud instance with a minimum of 3 vCPUs. Scaling an existing SAP HANA Cloud instance up from 2 to 3 vCPUs currently also requires a service request and this can be combined.
The SAP HANA Cloud trial instance is fixed a 2 vCPUs and does not support AFLs (time of writing).
