🤖 T-ECD presented at ACM KDD 2026
T-Technologies presented the T-ECD dataset — 135 billion anonymized interactions from 44 million users and 30 million items across five T-Bank domains. It is published on Hugging Face under the Apache 2.0 license.
🌍 The largest open dataset for recommender systems. Cross-domain data yields a +31.5% improvement for promotions but a −25.5% drop for food products.
👤 The small version (~1 billion interactions, ~3.5 million users) works without a GPU. Ready-made benchmarks are available from ALS to HSTU.
