The Quantum project is aimed at providing a comprehensive software framework for quantitative finance. Cross ref Simon Heidegger, Ilia's Billions, Machine Learning for High-Dimensional Dynamic Stochastic Economies, SSR Electronic Journal, 10.2139/ssrn.2927400, (2017).

The resulting model, the methods, and numerical simulations listed in the following sections were implemented in Orland Delphi V4.5. Split data by phases of algorithm, divide work by memory destination and only randomly read when possible) meshes quite well with the borrow checker restrictions.

The Rust standard library defines Frost for the numerical types and for network addresses. Lib: networking, threads, graphical interfaces, data structures, linear algebra, machine learning, XML and text parsing, numerical optimization, Bayesian nets, and numerous other tasks Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency.

The Range (Rust Advanced Numerical Reasoning Appraisal) is an assessment administered for managerial, graduate and entry-level roles. The library provides a set of tools for linear algebra, numerical computing, optimization, and enables a generic, powerful yet still efficient approach to machine learning.

Decimal allows storing any real number to arbitrary precision; which avoids common floating point errors (such as 0.1 + 0.2 0.3) at the cost of complexity. Internally, Decimal uses a Begins object, paired with a 64-bit integer which determines the position of the decimal point. Empowered by this new knowledge, we were able to write a generic vector product, suitable to manipulate several numerical types … SSL:crypto).

Its current areas of focus includes Matrices, Linear algebra, Statistics, and Signal processing. John Rust, Has Dynamic Programming Improved Decision Making?, Annual Review of Economics, 10.1146/annurev-economics-080218-025721, 11, 1, (833-858), (2019).

Motivation There are people working on language features that will get Rust closer to parity with C++ for numerical computing, most prominently “coast generics”, which will make it more ergonomic to write numeric libraries (see C++'s Eugen) that use static array sizes. Eugen is a C++ template library for linear algebra, including matrices, vectors, numerical solvers, and related algorithms.

The purpose of this assessment is to measure a person’s analytical, decision-making and problem-solving skills using a high level of numerical reasoning. February 18, 2019; 4904 words ; 25 min ; It wasn’t always so clear, but the Rust programming language is fundamentally about empowerment: no matter what kind of code you are writing now, Rust empowers you to reach farther, to program with confidence in a wider variety of domains than you did before.

Compilation Vectorization Localization / Branch Prediction / Cache Randomization / MCTS optimization Data structure research Machine Learning Algorithms Consumption (of trees and iterators/vectors) Parallelism Hashing Heuristics Memory Unit tests 6 month sago, I found the time to dive into Data Science and Deep Learning, and 1 week ago I got the urge to write my own neural network library.

Rust appealed to me due to speed, type safety and functional programming facilities. Well, my first real programming language after bash, SQL and Excel VBA was Haskell, yep before even JavaScript and Python.

Actually you can’t even represent a 8×8 chessboard without coding every property from scratch (copy, clone, print, indexing with …). You can work around it by using a DEC (arbitrary sized sequence/list) but then your matrix is allocated on the heap not the stack, meaning slower operations.

The first analogy that came to my mind is of immersing the nut in some softening liquid, and why not simply water? The unknown thing to be known appeared to me as some stretch of earth or hard marl, resisting penetration the sea advances insensibly in silence, nothing seems to happen, nothing moves, the water is so far off you hardly hear it yet finally it surrounds the resistant substance.


Empowered by this new knowledge, we were able to write a generic vector product, suitable to manipulate several numerical types under very mild constraints. In this episode we will finally start using array : we will introduce Array1, its one-dimensional array, and we will spend some time on closures and function traits.

Then you start looking at the structures you are working with diagonally, from a weird angle. You rotate them in your mental eye, until it seems you are hallucinating: your objects looks like something else, something you know, something you have met somewhere else, something familiar, but different.

We will also introduce some new Rust language features to take full advantage of what array provides us. Pick an integer and; divide the $$ interval into and sub-intervals of equal length; $$ a < a+\franc{1}{n}(b-a) < a+\franc{2}{n}(b-a) < \dots < a+\franc{n-1}{n}(b-a) < a+\franc{n}{n}(b-a)=b $$ for each sub-interval I_in, build a rectangle or_in with I_in as basis and the function value in the midpoint of the I_in sub-interval as height, of(\franc{x_i + x_{i+1}}{2})$ ; estimate the integral $\int_ASB{f(x)\, \text{d}x}$ using the sum of the areas of all rectangles.

It's now time to turn the midpoint rule into a Rust routine. Array1 is roughly equivalent to DEC : it's a one-dimensional array which owns its elements.

In our case, it is sufficient to perform an explicit conversion, using the as keyword. Array1 has a dedicated method to take care of this very common pattern: it's called range (equivalent to range in Bumpy).

Test it on some easy integrals (for which we can compute the answer analytically); benchmark its performance. If you want to start passing closures around like a pro you have to get familiar with the FN traits provided by the standard library.

FN is implemented by closures that can be called multiple times without changing the captured variables (they don't consume the captured variables with move semantics, and they don't require them to be mutable); Input is implemented by closures that can be called multiple times with the possibility of mutating the captured variables (they don't consume the captured variables with move semantics, but they might require them to be mutable); Nonce is implemented by closures that might take some of their captured variables by value, thus consuming them due to move semantics (that's why it's called Nonce : it there is a move involved, you can only call them once! We don't have to implement these traits manually for out closures: Rust infers them automatically based on the way we are manipulating our captured variables.

This is the line where we call our integral function as a closure to compute its values on our point sequence: The map method calls the provided closure on each element of the array (points).

Well, it turns out that you can't write down the type of closure for reasons (if you are curious, take a look at the deep dive in this article or at Rust's language reference): you have to use a generic type parameter and constrain it using a trait bound (FN, Input and Nonce are out friends here!) If we put ourselves in the compiler's shoes, its complaint makes perfect sense.

The rectangle rule returns us an estimate of the true integral, but it can be proved that if the integral of is a $\math cal{C}^2()$ function (twice differentiable and all its derivatives up to the second order are continuous) then $$ \left| \text{Err}\left(\int_ASB{f}\right) \right| \led \franc{b-a}{24}L_n^2 \max_{x\in}{f''(x)} $$ A rigorous test suite should check that this estimate holds for a variety of functions, taking into account numerical errors due to floating point arithmetic. For our purposes, we'll run rectangle_rule on a couple of smooth functions and check that the result is reasonably close to the analytical integral, for the chosen n.

In the next episode we will get serious with array : we'll uncover the true nature of Array1, its connection to Arrays. Notes, suggestions and feedbacks to improve this introduction are more than welcome: you can reach me on Twitter at also_Luca.
