kandi X-RAY | nrd Summary

nrd is a JavaScript library typically used in Server, Runtime Evironment, Nodejs, NPM applications. nrd has no bugs, it has no vulnerabilities and it has low support. You can install using 'npm i nrd' or download it from GitHub, npm.

Download an npm registry package tar file directly. nrd is short for npm registry download. It is also for nerds. nrd is useful for easily inspecting source code of modules and creating project scaffolds. Instead of creating a repo that has a template folder inside of it and copying files over, a project can be versioned, and directly downloaded from npm into a project without dependency resolution issues. For example:.

Initial value for Newton-Raphson Division algorithm when input is close to 0

Asked 2021-Feb-20 at 23:05

I am implementing a Newton-Raphson Division algorithm for values from [-16:16] in S15.16 over an FPGA. For values from |[1:16]| I achieved a MSE of 10e-9with 3 iterations. The way that I have initialized the value a0 is doing the inverse of the middle point in each range:

Some examples are:

From range 1 <= x < 2: a0 = 2/3
From range 6 <= x < 7: a0 = 2/13
From range 15 <= x < 16: a0 = 2/31

This approximation works well, as can be see in the following plot:

So, the problem here is in the range contained within [0:1]. How to find the optimal initial value or an approximation for the initial value?

In the wikipedia says that:

For the subproblem of choosing an initial estimate X0, it is convenient to apply a bit-shift to the divisor D to scale it so that 0.5 ≤ D ≤ 1; by applying the same bit-shift to the numerator N, one ensures the quotient does not change. Then one could use a linear approximation in the form

to initialize Newton–Raphson. To minimize the maximum of the absolute value of the error of this approximation on interval [0.5,1], one should use

Ok, this approximation works well for the range [0.5:1], but:

whats happens when the value tends to get smaller, close to 0. E.g: 0.1, 0.01, 0.001, 0.00001... and so on? I see a problem here because I think is necessary a initial value for each range between [0.001:0.01], [0.01:0.1]... etc.
For smaller values, is better apply other algorithm such as Goldschmidt division algorithm?

These are the codes that I have implemented to emulate the Newton-Raphson division in fixed point:

ANSWER

Answered 2021-Feb-20 at 23:05

The ISO-C99 code below demonstrates how one can achieve an almost correctly rounded implementation of Newton-Raphson based s15.16 division, using a 2 kilobit lookup table for the initial reciprocal approximation, and a number of 32x32-bit multipliers capable of delivering both the low 32 bits of the full product and the high 32 bits. For ease of implementation the signed s15.16 division is mapped back to unsigned 16.16 division for operands in [0, 2³¹].

We need to make full use of the 32-bit data path throughout by keeping operands normalized. In essence we are converting the computation into a quasi floating-point format. This requires a priority encoder to find the most significant set bit in both the dividend and the divisor in the initial normalization step. For software convenience, this is mapped to a CLZ (count leading zeros) operation, present in many processors, in the code below.

After computing the reciprocal of the divisor b we multiply by the dividend a to determine the raw quotient q = (1/b)*a. In order to round correctly to nearest or even we need to compute the remainder for the quotient a well as its increment and decrement. The correctly rounded quotient corresponds to the candidate quotient with the remainder of smallest magnitude.

In order for this to work perfectly, we would need a raw quotient that is within 1 ulp of the mathematical result. Unfortunately, this is not the case here, since the raw quotient is occasionally off by ±2 ulps. We would need effectively 33 bits in some of the intermediate computation, which could be simulated in software but I don't have time to puzzle this out right now. The code "as-is" delivers the correctly rounded result in more than 99.999% of random test cases.

The -s option itself is short equivalent to --loglevel=silent which disables logging output.

Well from the StackTrace , you are using Weld with Tomcat. Using Weld in the Tomcat requires configuration in order to integrate Weld and Tomcat. However , such integration is no longer required when switching to GlassFish/Payara as they already support Weld out of the box.

So , I think you have to remove all configuration about integrating Tomcat and Weld first. I suggest you make sure to remove all the configurations mentioned here first.

Vectorising (or speeding up) a double loop with summation over non-identical indices in R

Asked 2018-Feb-26 at 13:20

I am trying to optimise the code designed to compute double sums of product of the elements of two square matrices. Let’s say we have two square matrices of size n, W and V. The object that needs to be computed is a vector B with elements

In simple terms: compute element-by-element products of two different rows in two different matrices and take their sum, then take an extra sum over all rows of the second matrix (sans identical indices).

The problem is, the computational complexity of this task seemingly O(n³) because the length of this object we are creating, B, is n, and each element requires two summations. This is what I have come up with:

For given i and j (i≠j), start with the inner sum over k. Sum for all k, then subtract the terms for k=i and k=j, and multiply by the indicator of j≠i.
Since the restriction j≠i has been taken care of in the inner sum, the outer sum is taken just for j=1,...,n.

If we denote , then the two steps will look like and .

However, writing a loop turned out to be very inefficient. n=100 works quickly (0.05 seconds). But, for instance, when n=500 (we are talking about real-world applications here), the average computation time is 3 seconds, and for n=1000, it jumps to 22 s.

The inner loop over k can be easily replaced by a sum, but the outer one... In this question, the suggested solution is sapply, but it implies that the summation must be done over all elements.

This is the code I am trying to evaluate before the heat death of the Universe for large n.
