“…This method was dependent upon a conventional neural network (CNN) with long short-term memory networks (LSTM) for capturing the temporal data. In Zhang and Zeng (2022), touch gestures were predictable by a trained radial basis function (RBF) network, but integrated gestures can be demonstrated by Petrinet, which establishes a logic, timing, and spatial relationship model. As a result, the Braille input regarding multi-touch gesture recognition was executed.…”

“…It can be seen that, with the increase of center distance, multiquadric is a monotonically increasing function, while Gaussian and inverse multiquadric are monotonically decreasing functions. For monotonically decreasing function, when the variable is close to the function center, the function can obtain a large value; otherwise, its value tends to 0. erefore, monotonically decreasing function has good local characteristics [16]. us, when RBFNN basis function is selected, monotonically decreasing function is usually used.…”

“…To make the data samples meet the input and output requirements of the Gaussian-RBFNN model, before model prediction, premnmx and postmnmx functions in MAT-LAB7.0 are called to perform normalization and inverse normalization for the input and output models, respectively. e normalized data format of premnmx is shown in formula (16), and the reverse-normalized data format of postmnmx is shown in formula (17) [28,29]:…”

“…Therefore, non-linearity is one feature of hand gestures that should be dealt with. It is done through the metadata and content data carried by the images (Zhang and Zeng, 2022). The metadata of hand gesture imageries is utilized for detecting the gestures.…”
