Best Data Visualization Projects of 2024
Many datasets were analyzed and many charts were made this year. If I liked a project, it was on FlowingData. But only a handful can be the best. These are my favorite data visualization projects from 2024…A Gentle Introduction to Using a Vector Database
In which we learn how to build a simple vector database using Pinecone and OpenAI embeddings, and discover it was way easier than we might have expected…Quick recap on the state of reasoning
This is a talk I gave at NeurIPS at the Latent Space unofficial industry track. I wanted to directly address the question on if language models can reason and what o1 and the reinforcement finetuning (RFT) API tell us about it. It’s somewhat rambly, but asks the high level questions on reasoning that I haven’t written about yet and is a good summary of my coverage on o1’s implementation and the RFT API…Is it too late for me as 32 years old female with completely zero background jump into data engineering? [Reddit Discussion]
I’ve enrolled in a Python & AI Fundamentals course, even though I have no background in IT. My only experience has been in customer service, and I have a significant gap in my employment history. I’m feeling uncertain about this decision, but I know that starting somewhere is the only way to find out if this path is right for me…Anyone can share their experience or any advice? Please helpp, really appreciate it!…Three-Sided Testing to Establish Practical Significance: A Tutorial
Researchers may want to know whether an observed statistical relationship is either meaningfully negative, meaningfully positive, or small enough to be considered practically equivalent to zero. Such a question can not be addressed with standard null hypothesis significance testing, nor with standard equivalence testing. Three-sided testing (TST) is a procedure to address such questions, by simultaneously testing whether an estimated relationship is significantly below, within, or above predetermined smallest effect sizes of interest…In this paper, we give a non-technical introduction to TST, provide commands for conducting TST in both R and Jamovi, and provide a Shiny app for easy implementation…Multiple Regression with StatsModels - Look at predictions, not parameters
In this chapter we’ll get farther into regression, including multiple regression and one of my all-time favorite tools, logistic regression. These tools will allow us to explore relationships among sets of variables. As an example, we will use data from the General Social Survey (GSS) to explore the relationship between education, sex, age, and income…Let's Build a Simple Database
Writing a sqlite clone from scratch in C…Linear Algebra : Essence & Form
I am about to teach a new applied linear algebra course at [at]PennEngineers , meant for datasci/ML/AI. to support the class, i've written a book…Every month I send my team at Google a few paper recommendations. For this end-of-year blog post, I went through all my monthly emails, picked my favorite articles, and I grouped them into categories. In each category I kept them ordered by publication date, so you may get a sense of progress in each of them…
Gradient boosting machines, a tutorial
This article gives a tutorial introduction into the methodology of gradient boosting methods with a strong focus on machine learning aspects of modeling. A theoretical information is complemented with descriptive examples and illustrations which cover all the stages of the gradient boosting model design. Considerations on handling the model complexity are discussed. Three practical examples of gradient boosting applications are presented and comprehensively analyzed.Multi-modal Catalog Attribute Extraction Platform at Instacart
Attribute creation is a process of sourcing attribute information for products in Instacart’s catalog; for example, sourcing the attribute “sheet_count” for all our napkins products. It’s a critical foundation for a broad range of features that enhance the customer shopping experience across our platforms…To effectively support the attribute drive user experiences at Instacart, our attribute creation system needs to meet two core objectives: (1) generate highly accurate attribute data, and (2) scale to accommodate millions of products with thousands of diverse attributes…Imputation Use Cases [Reddit Discussion]
I’m wondering how and why people use this technique. I learned about it early on in my career and have avoided it entirely after trying it a few times. If people could provide examples of how they’ve used this in a real life situation it would be very helpful…I personally think it’s highly problematic in nearly every situation for a variety of reasons. The most important reason for me is that nulls are often very meaningful. Also I think it introduces unnecessary bias into the data itself. So why and when do people use this?..Stream processing, LSMs and leaky abstractions with Chris Riccomini
In this episode, we chat with Chris Riccomini about the evolution of stream processing and the challenges in building applications on streaming systems. We also chat about leaky abstractions, good and bad API designs, what Chris loves and hates about Rust and finally about his exciting new project that involves object storage and LSMs…
