The algorithm is formulated in the spirit of the famous FISTA method, however the setting is non-convex and we allow different inertial terms. We also treat the case when the non-smooth function is convex and we show that in this case a better step-size can be allowed. We prove some abstract convergence results which applied to our numerical scheme allow us to show that the generated sequences converge to a critical point of the objective function, provided a regularization of the objective function satisfies the Kurdyka-{\\L}ojasiewicz property.", "revisions": [ { "version": "v1", "updated": "2020-02-16T08:06:53.000Z" } ], "analyses": { "subjects": [ "90C26", "90C30", "65K10" ], "keywords": [ "inertial terms", "non-convex functions", "minimization", "abstract convergence results", "non-convex differentiable function" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable" } } }
