๐Ÿ’ฌ The survey takes about 10โ€“15 minutes and your feedback will directly inform the future development of our causal ML library.

โœ‰๏ธ Please feel free to share this with colleagues who use DoubleML.

Thanks! I totally agree with @mcknaus.bsky.social. Also whenever I start some new Causal "ML" projects, the first benchmark is always OLS & logistic regression learners; it helps you to see the connection to standard approaches; not only for linear regression, but also for doubly robust etc.

The causal part:

If you are a #causal #DAG enthusiast, you'll finde some causal diagrams and a discussion on causal aspects of demand analysis in the paper too ๐Ÿ˜€

The fun part (that's what you usually don't read in the papers):

Embedding text and image data makes demand analysis pretty accessible from an intuitive point of view. You can play around with the product embeddings, check for similarities and formulate/check hypotheses for various demand patterns

06.01.2025 08:42 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Our learnings:

We find that text and image data play an important role in predictive and causal demand analysis: Improved demand prediction and advanced heterogeneity analysis using product infos encoded in text and images, e.g., based on similarities and AI/data-driven product categorization.

Table 5 from the referenced paper showing the predictive performance of various models used for demand analysis. Deep learning based approaches that utilize both image & text data are found to substantially better predict the quantity and price signals than traditional (linear regression with tabular features only) and ML learners (boosted trees with tabular features)

Our approach:

1๏ธโƒฃ Enhanced Predictions: AI-driven embeddings significantly improve the accuracy of sales rank and price predictions

2๏ธโƒฃ Improved Causal Inference: By fine-tuning embeddings for causal tasks, we uncover strong heterogeneity in price elasticity linked to product-specific features

and Roleplay". The categorization has been obtained in the referenced paper. More details in Table 4.

๐Ÿ†• New year, new working paper: Adventures in Demand Analysis using AI ๐Ÿ†•

Our question: How can we advance demand analysis using recent tools from AI (Deep Learning, LLMs etc)?

Our idea: Use information from text & images in digital marketplaces like Amazon

This looks like a pretty useful paper and - probably more importantly - a pretty useful practical procedure to find our what happens when running Causal Machine Learning. Balancing checks etc are common in traditional approaches (like PSM), but are usually mor tricky to assess in ML-based estimation

Regarding the Riesz representers: we have the analytical RRs implemented for the sensitivity part, but the data driven RR are still to be added. That's a bit experimental and not 100% clear how to integrate them in the package
