5 System Framework of IA2
As shown in Figure 3, IA2 operates through a structured two-phase approach, leveraging deep reinforcement learning to optimize index selection for both trained workloads and unseen scenarios. It depicts IA2’s workflow, where the user’s input workload is processed to generate states and action pools for downstream RL agents. These agents then make sequential decisions on index additions, adhering to budget
