Abstract
As fas as we are aware, using Sequence to Sequence algorithms for query expansion has not been explored yet in Information Retrieval literature. We tried to fill this gap in the literature with a custom Query Expansion system trained and tested on open datasets. One specificity of our engine compared to classic ones is that it does not need the documents to expand the introduced query. We test our expansions on two different tasks : Information Retrieval and Answer preselection. Our method yielded a slight improvement in performance in both two tasks . Our main contributions are :• Starting from open datasets, we built a Query Expansion training set using sentence-embeddings-based Keyword Extraction.• We assess the ability of the Sequence to Sequence neural networks to capture expanding relations in the words embeddings’ space.We afterwards started a quantitative and qualitative analysis of the weights learned by our network. In the second part, I will discuss what is learned by a Recurrent Neural Network compared to what we know about human language learning.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
