Intel® Data Analytics Acceleration Library is a different product.
The key difference is that Intel® Analytics Toolkit focuses on addressing productivity of a data scientist by providing simple programming environment. Intel DAAL focuses on productivity of C++ and Java* software developers who care about acceleration of their data analysis platforms and applications.
At the same time Intel Data Analytics Acceleration Library and Intel Analytics Toolkit can co-exist and complement each other. Indeed the Analytics Toolkit provides a powerful front-end for data scientists to solve machine learning and graph analytics problems where DAAL is integral part of Hadoop-based backend which accelerates these algorithms.
