The global DRAM (Dynamic Random Access Memory) market size is about tens of billions USD, and keeps increasing due to growing demand of DRAM in mobile devices, modern computers, selfdriving cars, etc. It is crucial to test DRAM using various workloads in verifying and guaranteeing DRAM quality. DRAM manufacturers utilize their known workloads for verification; however, it does not guarantee that DRAM works well for new workloads not known in advance. Therefore, it is necessary to detect new workloads to improve the quality of DRAM verification. The problem of detecting new workloads is formulated as an open-set recognition [19] task which classifies a test sample into the known classes or the unknown class, and identifies its class if it belongs to the known classes. A workload sequence contains a series of tuples with the command and the address information of memory accesses. To detect new workloads based on open-set recognition, we exploit a subsequence, a part of the entire sequence of a workload. Given a subsequence, we classify it into one of the known workload classes or identify it as the unknown class corresponding to new workloads.

Countries looking to harness the power of disruptive technologies need to ensure that citizens, and particularly the poor and those left behind, benefit from the opportunities created by disruptive technologies. It is not enough that disruptive technologies lower costs of goods and services or provide other efficiencies. Jobs, education, social safety nets, and investments that give opportunities to the poor matter just as much. At this year's Annual Meetings of the International Monetary Fund and World Bank Group, stakeholders in the development community will, among many different topics, discuss how best to leverage the potential of disruptive technologies in order to address world's most pressing development challenges. Disruptive technologies include innovations that "lead to a step change in the cost or access to products and services with potential to disrupt traditional pathways of economic development."
