The NonUniform Memory Access (NUMA) machines are distributed shared
memory systems. In this paper, we extend conventional virtual memory
concepts to describe the status of memory in distributed, NUMA machines. We
present a mathematical model for virtual memory systems in centralized
systems and NUMA machines. The model will show the status of memory in
response to memory references.

Despite the enormous popularity of Translation Memory systems and the active research in the field, their language processing features still suffer from certain limitations. While many recent papers focus on semantic matching capabilities of TMs, thi
Neural-based summarization models suffer from the length limitation of text encoder. Long documents have to been truncated before they are sent to the model, which results in huge loss of summary-relevant contents. To address this issue, we propose t
