## Abstract (arXiv)

When one observes a sequence of variables (x1, y1), ldots, (xn, yn), Conformal Prediction (CP) is a methodology that allows to estimate a confidence set for yn+1 given xn+1 by merely assuming that the distribution of the data is exchangeable. CP sets have guaranteed coverage for any finite population size n. While appealing, the computation of such a set turns out to be infeasible in general, e.g. when the unknown variable yn+1 is continuous. The bottleneck is that it is based on a procedure that readjusts a prediction model on data where we replace the unknown target by all its possible values in order to select the most probable one. This requires computing an infinite number of models, which often makes it intractable. In this paper, we combine CP techniques with classical algorithmic stability bounds to derive a prediction set computable with a single model fit. We demonstrate that our proposed confidence set does not lose any coverage guarantees while avoiding the need for data splitting as currently done in the literature. We provide some numerical experiments to illustrate the tightness of our estimation when the sample size is sufficiently large, on both synthetic and real datasets.
