Recently, one of the most challenging tasks in the CALPHAD community is the development of the third generation CALPHAD databases and their application to re-assessment of binary, ternary and high-order systems from 0K [1-5, 13]. During the development of the third generation of CALPHAD databases, not only newly available DFT [4] and experimental data [5] should be considered to build a new pure elements database from 0 K, but the existing physical laws [6] and newly discovered relationships [7-9] between relevant thermodynamic properties should be established and integrated. Considering that the classical re-assessment procedure of high order thermodynamic systems is very time consuming, a combination of machine-learning (ML) methods with the well-established CALPHAD-type assessment will be presented as one of possible solution [10-12]. In this work, several successful partial applications of machine learning to accelerate and support the development the 3d generation CALPHAD database from 0K will be demonstrated.
