Talk 1: AI-Powered Carbon Emission Analytics from Public Transit Data - BVG Case Study Abstract: Imagine planning your route on Google Maps and alongside travel time, walking distance, and number of transfers, you also see the carbon footprint of each route. This project brings that idea to life by integrating real-time BVG transit data with an AI-powered emissions engine. Using segment-level routing information from Berlin’s public transport API, the system estimates CO₂ emissions for each journey based on the transport mode and distance. The dashboard calculates, visualizes, and even forecasts emissions over time using machine learning techniques like Prophet, while also detecting emission spikes and anomalies. It goes a step further by integrating a language model that explains emissions in plain language and recommends greener alternatives. The goal: to make sustainable commuting as easy and intuitive as choosing the fastest or cheapest route.

Speaker: Sirisha Padmasekhar Bio: Sirisha is a data scientist on the growth team at a queer social app, where she dives into data to uncover patterns in user behavior, retention, and content impact. She's especially drawn to data passion projects, anything that helps people see things a little more clearly through numbers and storytelling. Outside of work, she hosts a podcast where she interviews people from different walks of life, creating space for warm, honest conversations. For Sirisha, data and stories go hand in hand, both start with curiosity.

Talk 2: Lessons in Data Visualization from My Academic Journey Abstract: In this short talk, I’ll share practical opinions and approaches to data visualisation developed over years of storytelling to biologists in academia. Expect simple tweaks and tips to make your visuals more impactful and clear—without extra overhead—along with best practices from scientific publishing that I believe can benefit industry. These are personal takeaways that I hope will be useful in your day-to-day as well.

Speaker: Saulius Lukauskas Bio: Saulius Lukauskas is a data scientist with a Ph.D. in machine learning and an academic background in computational biology. He is currently a Data Science Manager at GetYourGuide, where he develops AI solutions to help suppliers deliver outstanding travel experiences.

The Lineup for the evening

Talk 1: FormatAI: Structuring Unstructured Text using generative AI Abstract: In the world of Natural Language Processing (NLP), the task of structuring unstructured text is akin to a translation task from free text into standardized formats like SQL or JSON. Generative AI is a great tool for this task, however, transformer-based translation models, such as GPT, sometimes struggle to adhere to the desired format, and to support the variety of expression of a natural language. In this session as we delve into the intricacies of using transformer-based models to extract information from natural language to a predefined structure. We'll explore effective best practices, including the Constrained Generative AI, a technique that can entirely eliminate syntactic errors. Additionally, we will journey through preprocessing, data generation and augmentation methods and training strategies, showcasing how these methodologies helped us achieve near-perfect accuracy in extracting dates and times within textual data. By the end of the session, you will gain insights into harnessing generative AI for structured output, opening doors to more accurate and efficient NLP applications. Speaker: Oren Matar is a principal data scientist and algorithms developer, working at Anaplan, with a background in social sciences and Bayesian methods. I’m specializing in NLP and time series forecasting particularly in the field of supply chain forecasting.

Talk 2: Probably Fun - games to teach statistics Abstract: I am currently field-testing gamified lessons for my statistics classes. "gamified" means playing with cards, dice, puzzles and more in a face-to-face classroom and then analyze the underlying statistical concepts. The games are a great way to build intrinsic motivation in students, promote understanding and foster cooperation among groups. Speaker: Kristian Rother is a freelance Python trainer who wrote his first lines of Python in the year `#07cf`. After a career writing software for life science research, he has been teaching Python, Data Analysis and Machine Learning throughout Europe since 2011. More recently, he has built data pipelines for the real estate and medical sector. Kristian has translated 5 Python books and written 2 more himself, in addition to numerous teaching guides. Kristian has collected 308 stars on Advent of Code. His knowledge about async is, unfortunately, miserable. His favorite Python module is `re`. Kristian believes everybody can learn programming. You can find Kristian's teaching materials on https://www.academis.eu

Join R-Ladies DC and R-Ladies Philly in June for an evening of short and insightful talks related to using R. Topics will highlight the breadth of use cases our members solve using R and the packages they love.

We will update the zoom link before the event.

Agenda: 6:00 - 6:10 - Join online 6:10 - 6:15 - Welcome and announcements 6:15 - 7:30 - Talks

Speakers and Talk Abstracts (in order of presentation):

• ‘Data wrangling in R for SAS users‘ by Priyanka Gagneja This talk is about how to make it easy to translate legacy SAS codes with R. This can be a good starting point for SAS programmers who don't know much R and for R users who do not know SAS.

• ‘Leveraging Open-Source Communities for Professional Development’ by Hebah Bukhari A few years ago I made a career switch and picked up R as a coding language. I didn’t have any coding background before. I began in an accredited program, but everything I learned about R and coding has been through the contribution of the R community and the help of its generous members.

• ‘Imaging R: An Interactive Web Application for Visualizing Multimodality Imaging Data Using R and Shiny’ by Kiki Zhang I developed an R-based web application that provides interactive image processing, analysis, and visualization. Multimodal data can be explored intuitively through the analysis pipelines comprising spectral density and time-lagged cross-correlation analyses for quantifying variation in neuronal dynamics and observing interaction dynamics patterns between signals.

• ‘Using the OpenAI API With Your Prompt + Your Data’ by Abigail Haddad I'll show how I'm using the R openAI package to work with the GPT-4 API. My example involves creating fake resumes by combining custom prompts with job-related data from a .csv file, showing how we can use the API to iterate through a dataset for text generation. I'll also mention a couple of NLP projects that I'm doing that use the same general format of prompt + iterating through text.

• ‘Tidyverse Style Guide’ by Arati Krishnamoorthy A guide to using the tidyverse style guide.

🔥 Greetings to all Kafka enthusiasts! Following the tremendous achievement of the previous Kafka meet-up in April, we are delighted to declare the forthcoming edition.

OSO are teaming up with Sainsbury's, special sponsor for this event, to deliver an exciting program of talks that you won't want to miss! ** Since this event will take place in a Sainsbury's office, for security purposes, you must register in your ID name order to gain entry. Register from here (scroll down for registry in the event page).

When: ⏰ Monday 26th June 2023 5.45 - 8:30 pm Where:📍33 Holborn, London EC4A 1AA Nearest Tube Stations: 🚇 Central Line: St. Pauls & Chancery Lane, Elizabeth Line: Farringdon

🎙️ \~Talk 1\~ Talk Title: Kafka enterprise strategy to evolve with demand Summary: In this talk we are going to navigate through the transformation journey of the Supply Chain BU adopting Kafka with microservices in an event-driven architecture to deliver better value to customers and have a look at the current presence of Kafka in Sainsbury’s. We will go over insights of early days, lessons learnt and successful governance patterns which made the onboarding smoother as time went. We will also review the different tooling involved in making this journey successful not only for business but for developers, along with leveraging Kafka community driven projects such as Kafka Connect. We will conclude on where the Kafka landscape and architecture is headed. Key talk takeaways:

• Plan for growth with a strong governance
• Give the tools to developers to be self-sufficient to reduce frictions
• Leverage existing solutions
• Breaking down silos to improve business adoption to deliver value faster with consistency
• Embrace innovative solutions and make the leap towards the future

🗣️ Speaker: John Mille (GitHub @johnpreston) – Principal Cloud Engineer at Sainsbury’s Coming from a Net/Sys admin background, John has been working with AWS (Amazon Web Services) and distributed systems since before he graduated. Introduced to Kafka on the job, he builds Open-Source tooling to help with Kafka Governance automation and enjoys occasional blogging, to share his experiences and help others.

🎙️ \~Talk 2\~ Talk Title: Enforcing Kafka Best Practices Summary: Kafka's flexibility and configurability have contributed to its widespread adoption, but they also pose challenges. The ability to configure applications client-side can lead to inefficiencies and performance issues within the Kafka cluster. Conduktor has encountered numerous instances of such issues reported by their customers, including improperly configured producers, consumer groups with excessive members, and mixed data and schema in topics unintentionally. These issues often go unnoticed by the client application but significantly impact the performance of the Kafka cluster. In this session, join us on a detective hunt as we explore the tools and metrics used to identify misconfigurations in clients. We will discuss strategies for addressing these issues once discovered and provide insights on preventing future occurrences. 🗣️ Speaker: Tom Scott: Principal Engineer, Conduktor Long time enthusiast of Kafka and all things data integration, Tom has more than 10yrs experience (5yrs+ Kafka) in innovative and efficient ways to store, query and move data. Currently working at Conduktor, Tom is building multi-tenant, on-prem and cloud Kafka services to attack common Kafka pain points and break down barriers to starting your data journey.

Talk 1: Debugging your reasoning (and code) with LLMs

Speaker: Jose Quesada

Abstract: You are familiar with using LLMs to be more effective while programming. Probably you get mediocre code quality, and debug it using your best judgment. The state of the art is moving fast and currently LLMs can self-debug the code they produce (by using the equivalent of rubber duck debugging). So what parts of programming do humans do better than machines? Can you improve these? In this talk I'll make the case that practical reasoning is one of these human advantages, and that you can improve it following a method (asking the assertibility question: 'what argument or evidence would justify me in believing the conclusion?'). We will see examples of how you can use this method to improve your daily life thinking. Programming has a distinct edge over general thinking - you can run the code and see if the result aligns with your expectations. However, when we're thinking in plain English, we lack this benefit. Throughout this discussion, I'll draw parallels. My hope is that you'll walk away with a practical technique to elevate your thinking.
