Approximate message passing (AMP) is a low-cost iterative parameter-estimation technique for certain high-dimensional linear systems with non-Gaussian distributions. However, AMP only applies to the independent identically distributed (IID) transform matrices, but may become unreliable for other matrix ...

Spiking neural networks (SNNs) incorporating biologically plausible neurons hold great promise because of their unique temporal dynamics and energy efficiency. However, SNNs have developed separately from artificial neural networks (ANNs), limiting the impact of deep learning advances for SNNs. Here, we...

Some research has explored how shared memory may be represented on multiprocessor machines such that its performance can approximate that of message-passing systems. For example, some memory models exploit the fact that synchronization is used to control access to a shared state, which allows the un...
In the area of memory management, a new policy, WSClock, is developed; this policy combines the natural load control of the WS (working set) policy and the simplicity and low cost of the Clock (approximate global LRU) policy. 展开
You can compute an approximate size for the KEEP buffer pool by adding together the blocks used by all objects assigned to this pool. If you gather statistics on the segments, you can query DBA_TABLES.BLOCKS and DBA_TABLES.EMPTY_BLOCKS to determine the number of blocks used.Calculate the ...

This scheme can be used to derive belief updates for each factor of the approximate posterior, and used to map out the connections (i.e., message passing) between different populations of neurons encoding the unknown variables (i.e., hidden states and policies). The results of this mapping ...
