The definition states that you should calculate theangle between two vectorsfirst. But you can’t represent some sentence as a vector in n-dimensional space just out of the box. You’ll want to construct a vector space from all the ‘sentences’ you want to calculate similarity for. That v...

These days, it is quite common for people to use therasterio,rasterstats,numpy, orgeopandasPython packages in their Raster processing/analysis workflows. This post aims to illustrate how some of these packages might be used to perform zonal statistics: rasterio rasterstats geopandas fiona If yo...
Standard deviationis a statistic parameter thathelps to estimate the dispersion of data series. It's usually calculated in two passes: first, you find a mean, and second, you calculate a square deviation of values from the mean: double std_dev1(double a[], int n) { if(n == 0) retur...
deviation, mean price) of a given equity or portfolio of equities over a specified lookback period. It then uses probability theory to calculate the maximum loss within your specified confidence interval. You can read more detailshere, but we'll calculate it step by step below using Python. ...
We can get RTT from the client-side JavaScript, but that does that mean we have the true end-to-end RTT from one client to another. If we use a media server such as MCU or SFU, then the RTT provided by browser stats is the RTT between the client-side and the media server – not...
The plot above shows the (normalised) mean values and standard deviations for ABC (right) and Primakoff (P; left) interactions. The grey bands illustrate the MC noise from 100 randomly chosen MC spectra. Revision of solar axion flux from axion-nucleon interactions Calculations of the axion flux...
In this tutorial, you will learn the different approaches to calculate the variance & the standard deviation in Python.What are Variance and Standard Deviation?Variance helps in measuring how far a number or value of a dataset is from the mean or average value. The variance measurement ...
The aircraft’s braking system works under the same principles as in cars, meaning that it transforms kinetic energy to thermal energy through friction. The overheating of the braking system leads to reduced performance and this is the reason that more than one stopping mean is mandatory for mode...
Sorting the returns in ascending order and finding the 5th percentile will give us the estimated value of dollar returns left to which is the first 252 ∙0.05=12.6 numbers. Then by (2.1.3) we compute the VaR to the mean and by (2.1.4) VaR relative to zero. These numbers are $229...
