The first builds a personalized gene regulatory network from the patient's tumor expression profile and layers in known drug-target relationships. The second uses a model pretrained on the LINCS L1000 dataset to simulate what the patient's gene expression would look like after drug exposure. A contrastive learning method — the same broad family of techniques behind image-text models like CLIP — pulls these two views into a shared space before making a classification. On The Cancer Genome Atlas benchmark, PREDIKTOR beat existing methods across patient, drug, and tissue evaluation splits. It also transferred to the I-SPY2 breast cancer trial without retraining, improving the area under the receiver operating curve by 5.6 percentage points over the next-best method.\n\nThe harder problem PREDIKTOR is attacking is the scarcity of matched clinical data: most patients have pre-treatment tumor profiles but no post-treatment molecular readout to train on. By combining a static knowledge-graph view with a dynamic perturbation simulation, the framework sidesteps needing that paired data at training time. The gene and pathway attributions it produces are also interpretable enough to recover known drug mechanisms — a requirement for clinical adoption that most black-box models skip.\n\nPrecision oncology has seen a wave of ML predictions that perform well on benchmarks and quietly disappear before a trial; zero-shot generalization to I-SPY2 is a more credible signal than TCGA accuracy alone, but prospective validation will still determine whether PREDIKTOR is a tool or a paper.","[\"ai\",\"oncology\",\"drug-response\",\"genomics\"]","2026-07-07T04:00:00.000Z","2026-07-07T13:32:17.760Z","2026-07-07T13:32:20.675Z","published",null,[],"ai",[24,26,27,28],"oncology","drug-response","genomics",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.04557",0,{"sections":35},[36,40,45,50,55,60,65,70,75,79,84,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":18},"Dev Tools","dev-tools",59,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
