bandwidth

问题 I am using sns.kdeplot(data) to obtain a Kernel Density Estimate for my 1 dimensional dataset. As I understand and having read seaborn's documentation on kdeplot, sns.kdeplot() passes bw_method="Scott" to scipy.stats.gaussian_kde to automatically obtain a rule-based bandwidth to smoothening the kde plot in question. Can I access the bandwidth that was automatically used by seaborn for its kdeplot? My idea was to reproduce seaborn's steps through scipy.stats.gaussian_kde and applying the rule

问题 I'm sure this has been answered before, but I can't find a good explanation. I'm writing a graphics program where a part of the pipeline is copying voxel data to OpenCL page-locked (pinned) memory. I found that this copy procedure is a bottleneck and made some measurements on the performance of a simple std::copy . The data is floats, and every chunk of data that I want to copy is around 64 MB in size. This is my original code, before any attempts at benchmarking: std::copy(data, data

问题 I am uploading data to Google cloud storage bucket using n processes parallelly, egress data rate is ~16Gbps. For only downloading data from gcp storage bucket using n processes parallelly, ingress traffic is ~26Gbps. But when I execute upload and download at the same time with same no. of processes, ingress rate reduces to ~7Gbps and egress to ~11/12Gbps. Using different buckets for upload and download. Instance and buckets are in the same region. Using Windows Server 2012 r2 OS and

问题 I want to create a bandwidth meter for Windows using vb.net, but I cannot seem to find anything in the .net framework for monitoring the amount of data in or out. I want to create this because I cannot find a good one for free, and I think it is something that people might want. If there is nothing in the .net framework for monitoring this, is there some P/Invoke calls I can make? If so, what are they? Is this project feasible? I want to try and measure the exact amount of data in and out,
