Does your production code look like it’s been copied from Untitled12.ipynb? Are your engineers complaining about the code but you can’t find the time to work on improving the code base? This talk will go through some of the basics of clean coding and how to best implement them in a data science team.

In the talk we give a brief overview of how we use Dynamic Pricing to tune the prices for rides based on demand, time of purchase, unexpected events strike etc., and other criteria to fulfil our business requirements.

Let’s say you are the ruler of a remote island. For it to succeed and thrive you can’t expect it to be isolated from the world. You need to establish trade routes, offer your products to other islands, and import items from them. Doing this will certainly make your economy grow! We’re not going to talk about land masses or commerce, however, you should think of your application as an island that needs to connect to other applications to succeed. Unfortunately, the sea is treacherous and is not always very consistent, similar to the networks you use to connect your application to the world.

We will explore some techniques and libraries in the Python ecosystem used to make your life easier while dealing with external services. From asynchronicity, caching, testing, and building abstractions on top of the APIs you consume, you will definitely learn some strategies to build your connected application gracefully, and avoid those pesky 2 AM errors that keep you awake.

This talk presents a novel approach to MLOps that combines the benefits of open-source technologies with the power and cost-effectiveness of cloud computing platforms. By using tools such as Terraform, MLflow, and Feast, we demonstrate how to build a scalable and maintainable ML system on the cloud that is accessible to ML Engineers and Data Scientists. Our approach leverages cloud managed services for the entire ML lifecycle, reducing the complexity and overhead of maintenance and eliminating the vendor lock-in and additional costs associated with managed MLOps SaaS services. This innovative approach to MLOps allows organizations to take full advantage of the potential of machine learning while minimizing cost and complexity.

Streamlit, a pure-Python data app framework, has been ported to Wasm as "stlite". See its power and convenience with many live examples and explore its internals from a technical perspective. You will learn to quickly create interactive in-browser apps using only Python.

Assessing the robustness of models is an essential step in developing machine-learning systems. To determine if a model is sound, it often helps to know which and how many input features its output hinges on. This talk introduces the fundamentals of “anchor” explanations that aim to provide that information.

Typing is at the center of „modern Python“, and tools (mypy, beartype) and libraries (FastAPI, SQLModel, Pydantic, DocArray) based on it are slowly eating the Python world.

This talks explores the benefits of Python type hints, and shows how they are infiltrating the next big domain: Machine Learning

A modern AI start-up is a front-end developer plus a prompt engineer" is a popular joke on Twitter. This talk is about LangChain, a Python open-source tool for prompt engineering. You can use it with completely open-source language models or ChatGPT. I will show you how to create a prompt and get an answer from LLM. As an example application, I will show a demo of an intelligent agent using web search and generating Python code to answer questions about this conference.

Jupyter Notebooks have been a widely popular tool for data science in recent years due to their ability to combine code, text, and visualizations in a single document.

Despite its popularity, the core functionality and user experience of the Classic Jupyter Notebook interface has remained largely unchanged over the past years.

Lately the Jupyter Notebook project decided to base its next major version 7 on JupyterLab components and extensions, which means many JupyterLab features are also available to Jupyter Notebook users.

In this presentation, we will demo the new features coming in Jupyter Notebook version 7 and how they are relevant to existing users of the Classic Notebook.

Many developers avoid using generators. For example, many well-known python libraries use lists instead of generators. The generators themselves are slower than normal list loops, but their use in code greatly increases the speed of the application. Let’s discover why.

The Python data ecosystem has matured during the last decade and there are less and less reasons to rely only large batch process executed in a Spark cluster, but with every large ecosystem, putting together the key pieces of technology takes some effort. There are now better storage technologies, streaming execution engines, query planners, and low level compute libraries. And modern hardware is way more powerful than what you'd probably expect. In this workshop we will explore some global-warming-reducing techniques to build more efficient data transformation pipelines in Python, and a little bit of Rust.

Data-driven products are becoming more and more ubiquitous. Humans build data-driven products. Humans are intrinsically biased. This bias goes into the data-driven products, confirming and amplifying the original bias. In this tutorial, you will learn how to identify your own -often unperceived- biases and reflect on and discuss the consequences of unchecked biases in Data Products.
