The essence of the paradox is that the signal-to-noise ratio in models can be unrealistically small and models may make better predictions of the observations than they predict themselves. The paradox highlights a potentially serious issue with model predictions as previous studies may underestimate ...
这篇论文提出了一个叫做参数的梯度信噪比(gradient signal to noise ratio)的概念,后文简记为GSNR,并且在此基础上建立了模型参数的GSNR与泛化程度之间的定量关系,这种关系表面,模型参数的GSNR越大,其泛化性能越好。 众所周知,传统的泛化性理论,如VC维数等无法解释神经网络强大的泛化性能,我们需要采用其他的方法来解释...
It is often questioned whether or not to use EMCCD gain or whether to use EM or conventional CCD amplifiers (model dependent). The answer usually depends both on required frame rate and on light levels. Plots of Signal to Noise ratio vs Signal Intensity can be instructive in making such ...
A proven strategy for addressing speech understanding in noise: until now, all proven signal-to-noise ratio benefits have been associated with microphone strategy and FM. Unitron's smartFocus offers a synergetic approach that further improves hearing in noise.(Hearing Aids)...
定义时间步t的对数信噪比(log signal to noise ratio, log SNR)为λ=log(αt2/σt2)。noise schedulefλ是一个将时间步t∈[0,1]映射为对应的 log SNRλ的函数,即有λ=fλ(t)。fλ是严格单调递减的。log SNRλ是一个关于t的函数,因此有时会将 log SNR 记为λt。noise schedule 的两端点为λmax...
Some several merits, use QDs: The signal intensity is brighter, the signal-to-noise ratio signal is a university, surpasses the ordinary fluorescence member greatly with the light stability.[translate] a你要树立起学习汉语的信心 You must set up the study Chinese the confidence[translate] ...
Many analog input specifications should be considered when selecting a wideband analog-to-digital converter (ADC) for a high performance system, such as ADC resolution, sample rate, signal-to-noise ratio (SNR), effective number of bits (ENOB), input bandwidth, spurious free dynamic range ...
It should be noted that the signal-to-noise ratio (SNR) is essentially proportional to 1/EVM or 1/MSE and can be used as loss function in principle. We use EVM/MSE as the cost function as they are common in both optical communications and machine-learning community24,25. Typically, ...
Wi-Fi packets are transmitted at a high rate over the air interface to obtain a high throughput. However, a higher packet transmission rate and a higher MCS require a higher signal-to-noise ratio (SNR). In other words, a higher packet transmission rate indicates a poorer anti-interference ...
we demonstrate an approach for the reduction of the hyperspectral data using a deep neural network approach. A combined deep neural network/least-square approach is shown to improve the effective signal-to-noise ratio of band-excitation piezoresponse force microscopy by more than an order of magnitu...
