07/28/2023, 2:30 PM3:00 PM UTC
32-124

The Bruno.jl package allows for pricing financial derivative assets under different theoretical models over varying time frames. This enables technical traders to formulate and test trading strategies within the package based on the derivatives themselves, rather than relying solely on the underlying assets. Using multiple dispatch, the simulating environment is left generic allowing for a wide range of uses from finance practitioners to academics.

14:40 UTC

ConstraintLearning: Ever wanted to learn more about constraints?

07/28/2023, 2:40 PM2:50 PM UTC
32-155

In many fields of optimization, there is often a tradeoff between efficiency and the simplicity of the model. ConstraintLearning.jl is an interface to several tools designed to smooth that tradeoff.

  • CompositionalNetworks.jl: a scaling glass-box method to learn highly combinatorial functions [JuliaCon 2021]
  • QUBOConstraints.jl: a package to automatically learn QUBO matrices from optimization constraints.

Applications are not limited to Constraint Programming, but are focused on it.

Debugging JuMP optimization models using graph theory

07/28/2023, 7:10 PM7:20 PM UTC
32-155

Writing a large optimization model is a time-consuming and error-prone task. If and when a modeling error is suspected, the developer often must re-consider every constraint in the model for faulty assumptions causing singularities in the optimization model, which impede convergence of solvers. We introduce a package that computes the Dulmage-Mendelsohn and block triangular partitions of incidence graphs of JuMP models, which can be used to detect sources of structural and numeric singularities.

Plasmo.jl and MadNLP.jl-A Framework for Graph-Based Optimization

07/28/2023, 7:20 PM7:30 PM UTC
32-155

Many optimization problems can be represented as a graph to provide useful visualization and to allow for manipulating and exploiting problem structure. We use Plasmo.jl (which extends JuMP.jl) to build optimization problems within a graph structure (where optimization model components are stored within the nodes and edges of the graph), and we use the nonlinear interior-point solver, MadNLP.jl, to solve these models and exploit some of these graph structures.

SingleCellProjections.jl - Fast Single Cell Expression analysis

07/28/2023, 7:30 PM8:00 PM UTC
32-G449 (Kiva)

We present an easy to use and powerful package that enables analysis of Single Cell Expression data in Julia. It is faster and uses less memory than existing solutions since the data is internally represented as expressions of sparse and low rank matrices, instead of storing huge dense matrices. In particular, it efficiently performs PCA (Principal Component Analysis), a natural starting point for downstream analysis, and supports both standard workflows and projections onto a base data set.

Robust data management made simple: Introducing DataToolkit

07/28/2023, 8:00 PM8:30 PM UTC
32-123

An ad-hoc approach to acquiring and using data can seem simple at first, but leaves one ill-prepared to deal with questions like: "where did the data come from?", "how was the data processed?", or "am I looking at the same data?". Generic tools for managing data (including some in Julia) exist, but suffer from limitations that reduce their broad utility. DataToolkit.jl provides a highly extensible and integrated approach, making robust and reproducible treatment of data and results convenient.

When type instability matters

07/28/2023, 8:10 PM8:20 PM UTC
32-144

Type instabilities are not always bad! Using non-concrete types, and avoiding method specialization and type inference can help with improving latency and, in specific cases, runtime performance. The latter is observed in inherently dynamic contexts with no way to compile all possible method signatures upfront, because code needs to be compiled at points of dynamic dispatch by design. We present a concrete case we face in our production environment, additional examples, and related trade-offs.

WTP.jl: A library for readable electronic structure code

07/28/2023, 8:20 PM8:30 PM UTC
26-100

The electronic structure theory is critical for understanding materials, but it has been challenging to develop readable yet efficient electronic structure packages. WTP.jl identifies a layer of abstractions that simplifies such development through an interface resembling the mathematical notation of the electronic structure theory. Using WTP.jl, we built another package SCDM.jl for electron localization with code far more readable than the widely used alternative Wannier90.
