A New Curve Fitting Based Rating Prediction Algorithm For Recommender Systems
Yilmaz, A. R.; Amrahov, Sahin Emrah; Gasilov, Nizami A.; Yigit-Sert, Sevgi (2022)The most algorithms for Recommender Systems (RSs) are based on a Collaborative Filtering (CF) approach, in particular on the Probabilistic Matrix Factorization (PMF) method. It is known that the PMF method is quite successful ... -
Numerical solution of linear inhomogeneous fuzzy delay differential equations
Fatullayev, A.G.; Gasilov, Nizami A.; Amrahov, Sahin Emrah (2019)We investigate inhomogeneous fuzzy delay differential equation (FDDE) in which initial function and source function are fuzzy. We assume these functions be in a special form, which we call triangular fuzzy function. We ... -
On differential equations with interval coefficients
Gasilov, Nizami A.; Amrahov, Sahin Emrah (2019)In this study, a new approach is developed to solve the initial value problem for interval linear differential equations. In the considered problem, the coefficients and the initial values are constant intervals. In the ... -
Relationship Between Bede-Gal Differentiable Set-Valued Functions and Their Associated Support Functions
Amrahov, Sahin Emrah; Khastan, Alireza; Gasilov, Nizami; Fatullayev, Afet Golayoglu (2016)In this study, we adapt the concept of the Bede-Gal derivative, which was initially suggested for fuzzy number-valued functions, to set-valued functions. We use an example to demonstrate that this concept overcomes some ... -
Solution Method For A Non-Homogeneous Fuzzy Linear System Of Differential Equations
Gasilov, Nizami A.; Fatullayev, Afet Golayoglu; Amrahov, Sahin Emrah (2018)In this paper, we propose a new solution method to non-homogeneous fuzzy linear system of differential equations. The coefficients of the considered system are crisp while forcing functions and initial values are fuzzy. ... -
Solution of Linear Differential Equations with Fuzzy Boundary Values
Gasilov, Nizami; Amrahov, Sahin Emrah; Fatullayev, Afet Golayoglu (2014)We investigate linear differential equations with boundary values expressed by fuzzy numbers. In contrast to most approaches, which search for a fuzzy-valued function as the solution, we search for a fuzzy set of real ... -
Solving A Nonhomogeneous Linear System of Interval Differential Equations
Gasilov, Nizami A.; Amrahov, Sahin Emrah (2018)In most application problems, the exact values of the input parameters are unknown, but the intervals in which these values lie can be determined. In such problems, the dynamics of the system are described by an interval-valued ...
