Universiti Putra Malaysia through the Institute for Mathematical Research (INSPEM) with the Malaysian Academy of Mathematical Scientist (AISMM) are delighted to co-organise IQRAC2018. We will be working towards a fruitful conference where there is fertile exchange of information on the latest findings in the every changing field of mathematical sciences. As Sarawak pledges to embrace Big Data technology in their efforts for the Sarawak Digital Economy Transformation, it is apt that the IQRAC2018 conference theme reflects the relevance of the mathematical sciences in accepting the challenges of Big Data: “ Mathematical Challenges in Big Data Analytics ”.
