Parameter Estimation of Stellar Mass Binary Black Holes under the Network of TianQin and LISA
We present a Bayesian parameter estimation progress to infer the stellar mass
binary black hole properties by TianQin, LISA, and TianQin+LISA. Two typical
Stellar-mass Black Hole Binary systems, GW150914 and GW190521 are chosen as the
fiducial sources. In this work, we establish the ability of TianQin to infer
the parameters of those systems and first apply the full frequency response in
TianQin's data analysis. We obtain the parameter estimation results and explain
the correlation between them. We also find the TianQin+LISA could marginally
increase the parameter estimation precision and narrow the area
compared with TianQin and LISA individual observations. We finally demonstrate
the importance of considering the effect of spin when the binaries have a
non-zero component spin and great derivation will appear especially on mass,
coalescence time and sky location.Comment: 17 pages, 6 figures, comments welcom
Block Pruning for Enhanced Efficiency in Convolutional Neural Networks
This paper presents a novel approach to network pruning, targeting block
pruning in deep neural networks for edge computing environments. Our method
diverges from traditional techniques that utilize proxy metrics, instead
employing a direct block removal strategy to assess the impact on
classification accuracy. This hands-on approach allows for an accurate
evaluation of each block's importance. We conducted extensive experiments on
CIFAR-10, CIFAR-100, and ImageNet datasets using ResNet architectures. Our
results demonstrate the efficacy of our method, particularly on large-scale
datasets like ImageNet with ResNet50, where it excelled in reducing model size
while retaining high accuracy, even when pruning a significant portion of the
network. The findings underscore our method's capability in maintaining an
optimal balance between model size and performance, especially in
resource-constrained edge computing scenarios
