The model

TITAN-LINK 2.2

Complementary product recommendation model

TITAN-LINK is a proprietary Deep Learning architecture that recommends, for each product, the most relevant complements in actual usage — even those that don't surface from common purchases alone. The model can also steer these recommendations according to the store's priorities: margin, trends, seasonality, or categories to push.

Flow architecture

Your tools. Our relational layer. Your sales surfaces.

TITAN-LINK plugs directly into your existing stack. No migration, no rewrite. The catalog comes in. The right recommendations come out — everywhere your customer buys.

Explainability & customization

Every model ships with its reasoning — and with your priorities.

Open the calculation and follow the model’s full path, signal by signal, through to the recommendation or score it serves you: nothing is produced without your being able to redo the arithmetic. Then tune the model to your store’s priorities and strategy — margin, seasonality, categories to push, value horizon — you decide what it puts forward.

What the model pulled out of the block
Dropped from the complements: “Gel Nettoyant Doux Rosée — 300 ml Refill”, which would have ranked 2nd at +0.74. The two names share four words out of seven — 0.571, past the 0.35 threshold — and a 10-point penalty crushes the score of any such variant: refill, other size, other shade. It remains 1st in the alternatives, above. Dropped next by the diversity cap: the 4th and 5th face-care references of the top-15, three being there already.
Provenance
Complementarity vectors relearned on 04/06/2026 (bi-monthly retraining) · 200 nearest neighbours retrieved, 15 reranked, 5 served · reranking scores recomputed 31 hours ago on your day’s sales and prices · 3 aisles represented, diversity cap respected · 0 filler items.
Demonstration: these settings are not saved and train no model. They do recompose the block preview at the bottom of this section, though — you read there the exact shape your setup would take.
Model objective
set at configuration time
Maximum revenue
Maximum gross margin
The model maximises a single quantity, and everything else follows from it: the ranking, the bonuses, the trade-offs. The objective is chosen once, with your Titane team, because it changes what the model is trained on — not merely how its output is sorted. The three settings below apply to the ranking produced by that objective.
Boost
Push a reference, a whole aisle, your most profitable products, or your latest releases towards the top of the ranking. The model keeps control of the order: a bonus moves a product, it does not glue it to the top.
Attributes

Products
Exclude
Remove a reference, a whole aisle, or your site’s oldest products from the block. An exclusion is firm: the product no longer comes out, whatever its score.

Reserve
Keep one position in the block for a choice of your own. The model ranks the other 4 as usual: a reservation takes one slot away, it does not disorganise the rest.

A setting applies to all 104 references; the preview takes one as an example — the gel’s page, whose five lines are the ones in the block above. The movement shown on the right compares the position to the model’s own ranking. The preview applies fixed bonuses — named product +6, aisle +3.5, attribute +2.5 — to the ranking’s starting weight: it is a mock-up of the setting, not the 789-signal re-ranker.
Under the hood

A relational graph, customizable.

Product relational graph

TITAN-LINK builds a unified graph of several million connections between your products, from their attributes, their co-purchases, and their browsing trajectories. Not a table of rules. A network of affinities.

Fusion of 17 independent signals

Co-purchases, similarity, complementarity, gross margin, bestsellers, trend, upselling — fused into a single score per product-to-product pair. Each signal is weighted according to your business intent.

Cross-category inference

The model detects unexpected complements across distinct categories. Where your native modules see a boundary, TITAN-LINK sees an affinity.

Steerable business weighting

Each signal can be reinforced according to your goals — conversion, margin, discovery. Not a frozen algorithm. A commercial strategy executed across your entire catalog.
