Abstract

In oncology, Deep Learning has shown great potential to personalise tasks such as tumour type classification, based on per-patient omics data-sets. Being high dimensional, incorporation of such data in one model is a challenge, often leading to one-dimensional studies and, therefore, information loss. Instead, we first propose relying on non-fixed sets of mutated genome sequences, which can be used for supervised learning of oncology-relevant tasks by our Transformer-based Deep Neural Network, SETQUENCE. Second, we extend the model to incorporate these representations as well as multiple sources of omics data in a flexible way with SETOMIC. Evaluation, using these representations, shows improved robustness and reduced information loss compared to previous approaches, while still being computationally tractable. By means of Explainable Artificial Intelligence methods, our models are shown to be able to recapitulate the biological contribution of several features in cancer, such as individual expression loci. This validation opens the door to novel directions in multi-faceted genome-wide biomarker discovery and personalised treatment among other presently clinically relevant tasks.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Jurenaite et al. reported that genes with highest attribution scores all carried known biological significance in cancer occurrence, providing confirmatory evidence on reliability of the AI system.

    “For the genetic data, the authors reported that the genes with the highest attribution scores all carried known biological significance in cancer occurrence, which provides valuable confirmatory evidence on the reliability of the AI system.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
