Data mining is a key component of modern business. It aids companies in enhancing customer affinities and improving sales by predicting future product sales and developing a future vision. The purpose of this study is to predict and assess retail sales. We aim to build a linear regression model to analyze supermarket store sales and make sales predictions. The dataset Supermarket Store Branches Sales Analysis is selected to evaluate the proposed model. Seven metrics are used in this study to examine the classifier, namely Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), Root Mean Squared Log Error (RMSLE), Mean Absolute Percentage Error (MAPE), R2 score, and Adjusted R2. The results of this study have shown that the model achieved 0.015729 in R2 score and 27.8% in Mean Absolute Percentage Error (MAPE).

In this paper, based on the six-degree-of-freedom dynamic model of multi-parafoil system, a state variable consensus control method based on time consensus is proposed by using multi-agent cooperative control theory. Through theoretical analysis, the upper bound of control time to ensure the convergence of state variables is determined. Then, the control input is transformed into a general formation control protocol, and the reference motion mode is designed, which provides a feasible scheme for practical application. Finally, numerical simulation experiments are carried out to verify the effectiveness of the proposed method. The results show that the system state variables such as speed and yaw angle can converge to the expected value within the specified time, which meets the coordination requirements of group performance. This study provides a new theoretical basis for the cooperative control of multi-parafoil system, which is helpful to improve the accuracy and coordination of group parafoil performance and lay a foundation for further research.

An extensive knowledge of cognitive development from early infancy to late adolescence is required to investigate brain neural pathways. The success in recognizing diverse stimuli is one of the remarkable frameworks that used to examine the essential variations in cognitive processes. Recognizing the intended stimuli has been proven to be influenced by several factors such as participants ‘gender and handedness. In this study, we investigated whether these cognitive variations regarding handedness take place at age nine-year. 33-EEG channels were recorded while seven right-handed and seven left-handed participants completed the Eriksen Flanker task-experimental paradigm with a variety of stimuli for evaluating attention and cognition. In each handedness group, the imaginary coherence was computed to evaluate the functional connectivity of each child. It was observed that left and right-handers activate distinct cortical regions, particularly in the alpha and beta bands. Additionally, the findings showed that brain connectivity at the incongruent Flanker stimuli can be utilized to differentiate the two targeted group.
