The pith

DOME edits decoder mappings in generative retrieval models to handle new documents using hybrid soft-hard labels.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

Generative retrieval reformulates search as generating document IDs, but new documents break the decoder's mappings from hidden states to those IDs. Full retraining works yet demands heavy compute and risks erasing prior knowledge. The paper shows that targeted model editing can fix the mappings instead. DOME identifies critical layers, optimizes edit vectors, and applies them after training those vectors on a mix of soft labels that keep query distinctions and hard labels that force exact ID changes. Tests on NQ and MS MARCO confirm gains on fresh documents, no loss on the original set, and roughly 60 percent of the time needed for incremental training.

Core claim

The decoder's mapping from hidden states to docIDs of new documents forms the central bottleneck; DOME resolves it by three stages of layer selection, hybrid-label optimization of edit vectors, and update construction, yielding measurable retrieval gains on added documents while preserving the original collection and using far less training compute than incremental fine-tuning.

What carries the argument

Hybrid-label adaptive training that mixes soft labels preserving query-specific semantics with hard labels enforcing precise docID changes to generate distinguishable edit vectors for targeted decoder updates.

If this is right

Retrieval effectiveness holds steady on the original document collection while rising on newly added documents.
Training cost drops to about 60 percent of the cost of incremental training.
Frequent model updates become practical because each edit targets only the decoder mapping rather than retraining the full model.
The same editing pipeline can be repeated whenever more documents arrive without restarting from scratch.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

If the hybrid labels succeed in separating vectors, the same editing pattern could extend to other generative tasks whose output vocabularies grow over time.
The method may offer a route to continual learning in retrieval systems where documents arrive in streams rather than batches.
Testing on collections that change daily or weekly would reveal how many successive edits the model can absorb before accuracy on old documents begins to slip.

Load-bearing premise

The decoder's mapping from hidden states to new docIDs is the main failure point, and hybrid-label training can produce edit vectors distinct enough to fix new mappings without damaging the existing ones.

What would settle it

A measurement showing that edit vectors for different queries remain too similar after hybrid training, or that applying the updates measurably harms accuracy on the original document set, would falsify the claim.

read the original abstract

Generative retrieval (GR) reformulates the Information Retrieval (IR) task as the generation of document identifiers (docIDs). Despite its promise, existing GR models exhibit poor generalization to newly added documents, often failing to generate the correct docIDs. While incremental training offers a straightforward remedy, it is computationally expensive, resource-intensive, and prone to catastrophic forgetting, thereby limiting the scalability and practicality of GR. In this paper, we identify the core bottleneck as the decoder's ability to map hidden states to the correct docIDs of newly added documents. Model editing, which enables targeted parameter modifications for docID mapping, represents a promising solution. However, applying model editing to current GR models is not trivial, which is severely hindered by indistinguishable edit vectors across queries, due to the high overlap of shared docIDs in retrieval results. To address this, we propose DOME (docID-oriented model editing), a novel method that effectively and efficiently adapts GR models to unseen documents. DOME comprises three stages: (1) identification of critical layers, (2) optimization of edit vectors, and (3) construction and application of updates. At its core, DOME employs a hybrid-label adaptive training strategy that learns discriminative edit vectors by combining soft labels, which preserve query-specific semantics for distinguishable updates, with hard labels that enforce precise mapping modifications. Experiments on widely used benchmarks, including NQ and MS MARCO, show that our method significantly improves retrieval performance on new documents while maintaining effectiveness on the original collection. Moreover, DOME achieves this with only about 60% of the training time required by incremental training, considerably reducing computational cost and enabling efficient, frequent model updates.

Desk Editor's Note private letter to a colleague

DOME adapts generative retrievers to new documents via hybrid-label model editing, but the evidence that the hybrid part drives the gains without side effects is still preliminary.

read the letter

The main takeaway is that this paper gives a concrete pipeline called DOME for updating generative retrieval models on fresh documents through targeted model editing instead of full retraining. It identifies the decoder's docID mapping as the bottleneck and uses a three-stage process: pick critical layers, optimize edit vectors with hybrid soft-plus-hard labels, then apply the updates. The hybrid strategy is the claimed novelty, meant to keep edit vectors distinguishable despite overlapping docIDs in retrieval results while avoiding catastrophic forgetting on the original collection. They report better performance on new documents in NQ and MS MARCO plus roughly 60 percent of the compute cost of incremental training, which is the practical angle that stands out.

Referee Report

3 major / 2 minor

Summary. The paper proposes DOME, a three-stage docID-oriented model editing method to adapt generative retrieval models to newly added documents. It identifies the decoder mapping as the core bottleneck, uses critical-layer identification followed by optimization of edit vectors via a hybrid soft+hard label strategy (soft labels to preserve query-specific semantics for distinguishability, hard labels for precise docID remapping), and applies the resulting updates. The central empirical claim is that DOME yields significant gains on new-document retrieval for NQ and MS MARCO while preserving effectiveness on the original collection, at roughly 60% of the training cost of incremental training.

Significance. If the central performance and efficiency claims hold under rigorous controls, the work would be a meaningful contribution to generative IR by offering a targeted, low-cost alternative to full retraining. It directly addresses the practical barrier of frequent document additions without catastrophic forgetting. The hybrid-label mechanism is a plausible adaptation of model-editing ideas to the high docID-overlap setting typical of retrieval, but its added value over simpler editing baselines remains to be isolated.

major comments (3)

[Experiments] Experiments section: the reported gains on NQ and MS MARCO lack any description of the exact baselines (e.g., which incremental-training variants or prior editing methods), statistical significance tests, or ablation of the hybrid-label component. Without these, the claim that DOME “significantly improves” performance while preserving original-collection effectiveness is only partially supported.
[Method (stage 2) and Analysis] Method (stage 2) and Analysis: the manuscript asserts that hybrid soft+hard labels produce “distinguishable edit vectors” that avoid side effects on existing docID mappings, yet provides no direct verification such as pairwise cosine similarity of edit vectors across queries or an ablation removing the soft-label term. The observed stability on old documents could therefore be explained by conservative update magnitudes rather than the claimed discriminative property of the hybrid strategy.
[Experiments] Experiments: no controls or measurements for catastrophic forgetting are described beyond the high-level statement that original-collection effectiveness is maintained. A quantitative comparison of per-docID generation accuracy before and after editing on the original collection would be required to substantiate the “no forgetting” claim.

minor comments (2)

[Abstract] Abstract: the phrase “significantly improves retrieval performance” is used without any numerical deltas, confidence intervals, or reference to the tables that contain the results.
[Method] Notation: the distinction between “edit vector” and “update” is used interchangeably in several places; a single consistent definition would improve clarity.

Referee: [Experiments] Experiments section: the reported gains on NQ and MS MARCO lack any description of the exact baselines (e.g., which incremental-training variants or prior editing methods), statistical significance tests, or ablation of the hybrid-label component. Without these, the claim that DOME “significantly improves” performance while preserving original-collection effectiveness is only partially supported.

Authors: We agree that the experiments section would benefit from more precise descriptions of the baselines used, including specific incremental-training variants and prior editing methods. In the revised manuscript, we will expand this section to detail the exact baselines, report statistical significance tests for the observed gains, and include an ablation study isolating the hybrid-label component. These additions will provide stronger support for our performance claims. revision: yes
Referee: [Method (stage 2) and Analysis] Method (stage 2) and Analysis: the manuscript asserts that hybrid soft+hard labels produce “distinguishable edit vectors” that avoid side effects on existing docID mappings, yet provides no direct verification such as pairwise cosine similarity of edit vectors across queries or an ablation removing the soft-label term. The observed stability on old documents could therefore be explained by conservative update magnitudes rather than the claimed discriminative property of the hybrid strategy.

Authors: We acknowledge that direct verification of the distinguishability of edit vectors is missing. To address this, we will include pairwise cosine similarity measurements of edit vectors across different queries in the analysis section. Additionally, we will perform and report an ablation study that removes the soft-label term to demonstrate its role in producing discriminative updates, separate from any effects of update magnitude. revision: yes

A quantitative comparison of per-docID generation accuracy before and after editing on the original collection would be required to substantiate the “no forgetting” claim.

Authors: We agree that a more rigorous quantification of catastrophic forgetting is necessary. In the revised experiments, we will add a quantitative comparison of per-docID generation accuracy on the original collection before and after applying DOME. This will provide concrete evidence that the editing process does not degrade performance on existing documents. revision: yes

Circularity Check

0 steps flagged

No circularity in derivation chain; method and claims are empirically grounded

full rationale

The paper introduces DOME as a three-stage model-editing procedure (critical-layer identification, hybrid-label edit-vector optimization, update construction) to adapt generative retrieval models to new documents. No equations, derivations, or self-referential definitions appear that reduce the claimed improvements (e.g., better new-document retrieval with preserved original-collection performance) to fitted parameters defined by the method itself or to self-citation chains. The hybrid-label strategy is presented as a design choice motivated by observed indistinguishability of edit vectors, not as a tautological fit. Experiments on NQ and MS MARCO are reported as external validation rather than predictions forced by the inputs. This is a standard empirical method paper with no load-bearing circular steps.
