Modelling with Probability

We will explore a data modelling problem through Bayesian Inference. Our main tool will be the Inferme library by Tomasz Sulej. We will see how it is possible to model our data through a 'forward' probabilistic process, and infer the unknowns by running it 'backwards'.

Computing Derivatives and Automatic Differentiation

Have you seen a Math or Physics Equation and wanted to work with them using your computer, but thought that you need some special language such as Matlab or Python? This talk will show that it is possible to accomplish this in Clojure using the SICMUtils Library. This talk will show how to do automatic differentiation in Clojure using the SICMUtils Library. I will explain what a derivative is, show how you can transcribe equations to a Clojure using the SICM and provide some background on auto differentiation. We will also demonstrate a nice workflow for these types of investigations using two other Clojure libraries: Clerk - a notebook that connects to your editor; Hanami - a charting tool built on Vega.

How to Talk with Data Scientists?

Engineers and Data Scientists work towards the same business goals, but sometimes have different concerns to get there. In this workshop, we'll review situations showcasing what data scientists need to be successful, and by consequence how engineers can better cope with those requests. Bring your stories and your questions!

    The Devil’s Interop: Invoking Clojure from Python Natively with GraalVM, and Other Such Matters as Related to Clojure Polyglot Blood Magick

    This is a workshop that demonstrates when, why, and how to compile Clojure code into a shared library that can be called natively by CPython (no runtime JVM required!), in the same way that Clojure code can be compiled into a Jar which can be used natively by Java.

    Structure and Interpretation of Clojure Transducers

    Transducers are a powerful abstraction added relatively recently to Clojure. In spite of this and the noticeable performance benefits, they remain a daunting subject for many Clojurians. There is no reason such an important subject remain impenetrable. We will approach them in this workshop from first principles and see how they emerge naturally as a general property in many places. By the end of the workshop, participants will have a better understanding of transducers, their use cases, and will be comfortable writing their own simple transducers when the need arises.

    An Intro to Statistical Inference

    Useful inferential statistics does not have to be just the domain of data scientists. This workshop follows examples in the book "Statistics is Easy" to demonstrate concepts of fairness, p-value, confidence intervals, power using resampling and bootstrapping. All concepts will be explained purely using functions from the core clojure library

    Your Namespace as a Notebook

    Notespace allows the creation of visual documents without leaving the comfort of the familiar Clojure editor, REPL, and namespace. It has evolved through usage in the Scicloj community. We will practice basic use of Notespace, discuss its design choices and relationship to other projects, and chat about future challenges.

    Visualizing Data with Hanami

    In this workshop we will explore how to visualize simple datasets using Hanami, a Clojure library for creating interactive visualizations built on top of Vega-Lite and Vega. There will be a brief explanation of how these tools work to start but we will spend most of our time exploring together, so it will be helpful to have a Clojure environment set up on your computer already.

    Wrangling Sequences Like a Cowboy with Injest

    Note: This workshop covers material that is best understood by reviewing a prior workshop: “The Structure and Interpretation of Clojure Transducers” Summary: Injest provides thread macros (e.g. x>>, =>>) that lower the bar to higher performance by letting you compose transducers in the same way as you would with ->>. In this workshop we will introduce you to injest’s three main features: path threads, auto transducification and auto parallelization. Then, we’ll go over some real world examples of transforming (wrangling) data sequences. We’ll spend the remaining time of the workshop in an open session, answering questions and trying things out at the REPL. I might even wear a cowboy hat, in further jest 🤠

    A Data Science Walkthrough

    In this session, we will get to know some of the main parts of the emerging Clojure data science stack. We will do that through the exploration of a real-world data modelling problem.

    Machine Learning Through Pipelines

    Scicloj.ml is a Clojure library by Carsten Behring that connects many aspects of machine learning workflows into one coherent stack. It is based on a certain notion of a pipeline, implemented in the libraries Metamorph and Metamorph.ml. In this session we will discuss some of the core ideas behind these libraries and look into solving a data modelling problem using Scicloj.ml.

    Touring Oz: Notebooks, Visualizations, and Webapps, Oh My!

    Oz is a Swiss Army Knife for data visualization, scientific documentation, and "namespace as a notebook" style analysis workflows. However, its versatility can make it easy to miss the full scope of its capabilities. In this workshop, we'll briefly go over all of its features, and then work through a series of illustrative examples based on participant interest.

    Linear Algebra with Neanderthal

    In order to operate mathematics on collections of numbers, the easiest solution is to use for-loop. I assumed it was the fastest way until I discovered Neanderthal, a linear algebra built for Clojure. This workshop introduces the most basic linear algebra concepts so that you can also enjoy Neanderthal. My aim will be to show you the underlying intuition so that these squares of numbers and formulas won't scare you when you read them.

    Writing Web Apps with Fulcro

    Fulcro is unique among Clojure web frameworks in providing a complete, integrated, full-stack solution for creating non-trivial web applications. It is based on a few simple ideas with far-reaching consequences, it is unusually malleable, and we love it for its focus on creating maintainable, developer-friendly code. In this workshop you will get a brief introduction to Fulcro and then get your hands dirty exploring the concepts in practice on an existing application in a series of guided exercises. We will use the excellent Fulcro Inspect tooling and mess up with the code. Please do the preparation described at https://github.com/holyjak/fulcro-intro-wshop#prerequisites before the workshop.

    Full-text Search Query Log Analysis

    In this workshop we are going to dive into the search query log analysis similar to what search engineers are doing day to day. I'll use tools written mostly in Clojure that helps to do a semantic query analysis with the goal of getting query templates. The examples are going to be relevant for E-Commerce search applications.
