Abstract According to an epistemic view of intervals, this paper proposes a possibilistic regression based on gradual interval B-splines to represent the input-output data mapping. In this context, an improvement of the parametric fuzzy regression through the notion of gradual interval B-splines is proposed. The proposed gradual regression based on B-splines can be regarded as an extension of the nonparametric interval-based regression where an uncertain dimension is integrated. The proposed met...

Abstract In this paper we propose a new method, Return Random Walk, for link prediction to infer new intra-class edges while minimizing the amount of inter-class noise, and we show how to exploit it in an unsupervised densifier method, Dirichlet densification, which can be used to increase the edge density in undirected graphs, setting so that commute times can be better estimated by state-of-the-art methods. Moreover, this approach allows us to predict new intra-class links by exploring vertex ...

Abstract Public key encryption with equality test (PKEET) allows a tester to check whether two ciphertexts encrypted under different public keys contain the same message without decrypting them. In this paper, we first introduce group mechanism into PKEET and propose a new primitive, namely group public key encryption with equality test (G-PKEET). G-PKEET can resist the attack that the tester can recover the message from a given ciphertext by exhaustively guessing the message offline. Furthermor...

Abstract The wide-spread mobile systems nowadays desire ultra lightweight local geometric features to accomplish tasks relying on correspondences. Nonetheless, most existing 3D local feature descriptors, though shown to be distinctive and robust, still are real-valued and/or high-dimensional. Accordingly, this paper conducts a comparative study on current bit-selection methods with a focus on shortening 3D local binary descriptors. By analyzing several bit-selection techniques, we develop and ev...

Abstract In this article, the notions of gH-directional derivative, gH-Gâteaux derivative and gH-Frechet derivative for interval-valued functions are proposed. The existence of gH-Frechet derivative is shown to imply the existence of gH-Gâteaux derivative and the existence of gH-Gâteaux derivative is observed to indicate the presence of gH-directional derivative. For an interval-valued gH-Lipschitz function, it is proved that the existence of gH-Gâteaux derivative implies the existence of gH-Fre...
