Differentiable modelling on GPUs
Ludovic Räss, Samuel Omlin, Ivan Utkin

Why to wait hours for computations to complete, when it could take only a few seconds? Tired of prototyping code in an interactive, high-level language and rewriting it in a lower-level language to get high-performance code? Unsure about the applicability of differentiable programming? Or simply curious about parallel and GPU computing and automatic differentiation being game changers in physics-based and data-driven modelling.

Building REST APIs with Julia
JAKE

Although Julia is a growing, fast language with relatively easy syntax, and thus quite a productive language, its popularity still seems enormously lopsided towards the scientific community. Thus it can be quite an intimidating language and community for newbies without heavy or good scientific or mathematical background to get into.

To address the intimidation above, I would like to propose this workshop, where we'll build and deploy a REST project for the web, a ubiquitous technology.

Using NeuralODEs in real life applications
Tobias Thummerer, Lars Mikelsons

NeuralODEs lead to amazing results in academic examples. But the expectations are often being disappointed as soon as one tries to adapt this concept for real life use cases. Bad convergence behavior, handling of discontinuities and/or instabilities are just some of the stumbling blocks that might pop up during the first steps. During the workshop, we want to show how to integrate real life industrial models in NeuralODEs using FMI and present sophisticated training strategies.

Evolving Robust Facility Placements
Will Thompson and Alex Friedrichsen, Alex Friedrichsen

Climate change is leading to an increase in natural disasters, such as floods and earthquakes, which can damage critical infrastructure like hospitals and schools. To address this problem, we propose a project that uses evolutionary algorithms to design facility placements that are robust to disaster. By using evolutioanary algorthims as a metaheursitc solution to the p-median problem, we are show that our approach leads to facility layouts that are more robust to natural disasters.

Julia in machining: optimizing drilling positions
Tamás Cserteg

In the machining of cast blank parts, small geometrical deviations between different lots of blanks can cause serious issues. These differences need to be compensated to 1) make sure that every feature on the blank is properly machined and 2) dimensional tolerances between features are respected. This poster shows via a case study in drilling that Julia is a great tool for solving this problem, including the steps of data processing, optimization, and visualization.

Sorting gene trees by their path within a species network
Nathan Kolbow

Evolutionary relationships are often depicted in tree structures where internal nodes represent ancestral species and external nodes represent extant species, but directed networks are often necessary. Many species tree and network estimation procedures first estimate a set of gene trees from sequence data. The proportion of these gene trees that do not necessitate a network model is biologically interesting. In RANSANEC.jl, we expand random sample consensus to tree-space to tackle this problem.

Fast Higher-order Automatic Differentiation for Physical Models
Songchen Tan

Taking higher-order derivatives is crucial for physical models like ODEs and PDEs, and it would be great to get it done by automatic differentiation. Yet, existing packages in Julia either has exponential scaling w.r.t. order (nesting first-order AD) or has exponential scaling w.r.t. dimension (nested Taylor polynomial in TaylorSeries.jl). The author presents TaylorDiff.jl (https://github.com/JuliaDiff/TaylorDiff.jl) which is specifically optimized for fast higher-order directional derivatives.

Wrapping Up Offline RL as part of AutoMLPipeline Workflow
Paulito Palmes

Unlike in Online RL where agents need to interact with real environment, Offline RL works similar to a typical machine learning workflow. Given a dataset, Offline RL processes data extracting state, action, reward, and terminal columns to optimize the policy Q. By wrapping up offline RL into the AutoMLPipeline workflow, it becomes trivial to search for the optimal preprocessing elements and their combinations to improve Offline RL optimal policy using symbolic workflow manipulation.

IsDef.jl: maintainable type inference
Stephan Sahm

IsDef.jl provides maintainable type inference in that it
1. Uses code generation where possible to deterministically infer the types of your code
2. Allows you to overload type-inference with your custom implementation
3. If neither code generation works nor a custom type inference rule is given, it falls back to Core.Compiler.return_type, wrapped by some safety nets

In this talk IsDef.jl is presented, along with typical applications and details about the implementation.

What's new with Progradio.jl - Projected Gradient Optimization
Eduardo M. G. Vila

Box-constrained optimization problems are ubiquitous in many areas of science and engineering. Our package includes methods tailored to this class of optimization problems. Due to Julia's Iterator interface, Progradio's solvers can be paused, resumed, or terminated early. Since the first release, we have included a stricter line-search procedure, and support for simplex constraints (Σ x_j = 1). Progradio's unique features make it attractive to be used as a sub-routine for dynamic optimization.

Julia with JuMP is an excellent alternative as it is both open source and allows for flexibility in model structure by using multiple dispatch. The model is a novel energy system model framework with easy extendibility and high flexibility.

Long range dependence modelling in Julia
J. Eduardo Vera-Valdés

Failing to account for LRD dynamics can perversely affect forecasting performance: a model that does not account for LRD misrepresents the true prediction confidence intervals. LRD has been found in climate, political affiliation and finance data, to name a few examples.
