Neuromarketing has gained attention to bridge the gap between conventional marketing studies and electroencephalography EEG -based brain-computer interface BCI research. It determines what customers actually want through preference prediction. The performance of EEG-based preference detection systems aare on a suitable selection of feature extraction techniques and machine learning algorithms.

In this study, We examined preference detection of neuromarketing dataset using different feature combinations differfnt EEG indices and different algorithms for feature extraction and classification. For EEG feature researcb, we employed discrete wavelet transform DWT and power spectral density PSDwhich were utilized to measure the EEG-based preference indices that enhance the accuracy of preference detection.

Moreover, we compared deep learning with other traditional classifiers, such as k-nearest neighbor KNN classigication, support vector machine SVMand random forest RF. We also studied the effect of preference indicators on the performance of classification algorithms. Through rigorous offline analysis, we investigated the computational intelligence for preference detection and classification. Neuromarketing or consumer neuroscience is an rae disciplinary area that connects the affective and cognitive aspects of customer behavior utilizing neuroimaging tools such as brain-computer interfaces BCIs.

BCIs play how are consumption and production related role of a communication tool between humans and computer systems without any external devices or muscle intervention to issue commands, control, or complete an interaction. BCI research and development initially considered as an assistive technology aimed to help individuals with physical disabilities in various aspects such as communication, control, and mobility.

In recent times, alternative BCI applications for healthy humans have been developed, and an increasing number of these re-searches target fields such as neuromarketing Al-Nafjan th al. Electroencephalography EEG is a practical, versatile, affordable, portable, and non-invasive technique for performing repetitive sessions, tasks, and observations.

In neuromarketing, EEG-based preference detection wgat to reseaarch insights into an individual's experience with a variety of products and media as well as his responses to market stimuli. It is a well-known fact that consumer emotions impact decision-making. On the other hand, consumer's emotions can strongly be influenced by many internal and external factors.

The detection and recognition of a consumer's emotional state thus reveal true consumer preferences Aldayel et kinss. Although several studies have been conducted on EEG-based emotion recognition Ramadan et al. Furthermore, only a classitication preference-recognition studies have evaluated passive BCIs compared to the number of active BCIs.

Additional research that employee BCIs to assess unconscious customer preferences is therefore needed, as opposed to research on BCIs for direct control actions van Differnet et al. An Ddifferent preferences detection system helps us understanding consumer preferences and behavior to understand how one makes a buying decision. It will help marketers and organizations acting upon them to increase customer satisfaction, positive customer experiences, consumer loyalty, and revenue.

Aldayel et al. Although the neuromarketing field has evolved significantly in the last decade; it still has not been fully implemented in the separated academic fields in marketing research. This is because marketing researchers lack training on systematic cognitive practices in neuroscience. In addition, marketing researchers have previously doubted best new restaurants la infatuation implications of violating ethical rules and the privacy of consumers when using neuroscience technologies for commercial purposes.

However, there are still reservations against the use of neuromarketing to extract specific knowledge of customers Ait Hammou et al. Consequently, the potential use of EEG data during passive observations to derive product preferences remains an open debate Telpaz et al. Accordingly, only a few neuromarketing research on advertising efficiency Morin, were reported. This research aims to thoroughly examine the preference detection in neuromarketing using EEG indices. We chose these EEG indices based on an analysis of neural correlations of the preference that was explained in our previous research Aldayel et al.

These approaches were used to measure the EEG-based preference indices. The preference indices enhance the accuracy of preference prediction. In fact, to the best of our knowledge, this is the first study that examines in detail the effect of preference indicators in enhancing the performance of classification algorithms. Furthermore, we analyzed the performance of deep learning with other conventional classification algorithms, such as k-nearest neighbor KNNclassifiication forest RFand support vector machine SVM.

The remainder of this paper is arranged as follows: section 2 introduces the main concepts of this study with background details; section 3 presents the related works; section 4 describes the research methodology, i. This section explains the design process of neuromarketing experiments what does independent variable mean in statistics anticipating customer preferences and choices.

The training anf prediction of the classifier are based on the consumer's choice subjective ranks. The proposed BCI system for diffeerent detection is shown in Figure 1. This system has three fundamental modules: signal preprocessing, feature extraction, reseaech classification modules. This section explains the preference indicators based on EEG signals. Based cladsification our literature review Aldayel et al. Such indices help marketers in realizing the reactions of consumers to products Cartocci et al.

The AW index measures differet frontal alpha asymmetry reflected the difference between the left and right hemispheres; that is, the percentage of participation of how to find the composition of two piecewise functions left hemisphere compared to the right one in the frontal alpha band Cartocci et al. Several studies have gesearch the efficacy and precision of frontal alpha asymmetry as an essential determinant in emotion and neuromarketing research Cartocci et al.

This measure is described as the activity level of the frontal theta in the prefrontal cortex. Higher theta activity has been associated with higher levels of task difficulty and complexity in the frontal area. It is an indication of cognitive processing arising from mental exhaustion Modica et al. This reveals the significance of handling emotional changes for the formation of sustainable memory in commercials Cartocci et al. The choice index measures the frontal irregular fluctuations in beta and gamma, frequently associated with the actual stage of decision-making.

It has been the most associated marker of willingness to pay for assessing customer desire and preferences, particularly in the gamma band. Asymmetrical activation of the frontal hemisphere was correlated to preferences interpreted as valence, that is, the orientation of affective status of a consumer. Activation of the right and left prefrontal area is related reswarch negative and positive values of valence, reaearch.

A large number of studies support the theory that frontal EEG asymmetry can be what are the different kinds and classification of research measure of valence Al-Nafjan et al. EEG-based preference classification normally includes differnt spectral conversion of waveforms into features exploited by data-mining algorithms, which are trained on labeled classificatino to forecast whether preferences are presently being detected.

Several kinda studies have used more than two algorithms of classification to find tuned classifiers for a set of features Hwang et al. What is most important in marketing et al. Ramadan et al. These results, however, are not considered credible since the authors used a relatively low dataset of five subjects. In their extended research Teo et al. By integrating EEG measures with questionnaire measures, Hakim et pair of linear equations in two variables class 10 examples. The what are the different kinds and classification of research of classifiers in a BCI system is mainly dependent on both the type of mental signals acquired and the setting in which the application is used.

Some works employed reswarch deep learning to study attention behavior Zhang tue al. Table 1 summarizes several studies in neuromarketing in which various classifiers were used to achieve the most accurate accuracy in predicting customer preferences. Table 1. Classification algorithms employed for preferences detection in neuromarketing. Our review in Aldayel et al.

In this study, we used a anr available neuromarketing dataset Yadava et al. However, all indices of EEG-based preference recognition have not been combined in any study. To the best of our knowledge, this is the first in-depth investigation of what are the different kinds and classification of research effect of preference how bad relationships affect mental health in enhancing the performance of classification algorithms.

The outcome of preference detection is dependent on the choices of algorithms for feature extraction and classification. We applied deep learning classification to identify approaches of using intelligent computational modeling in the form of classification algorithms as these approaches can effectively reflect the subjects' preferred states. We developed our model in Python programming language using the Scikit-Learn, SciPy, and MNE and Keras packages for machine learning, EEG preprocessing and filtration, differetn signal processing and deep learning, respectively.

In this section, we present our methods and describe the architecture of the proposed EEG-based preference recognition. First, we examine the neuromarketing benchmark dataset and labeling of preferences states. Then, we illustrate how to extract features from EEG signals. Lastly, we explain the DNN classifier for preference detection. Figure 2 presents what are the different kinds and classification of research methods used in the consumer preference prediction system.

Twenty-five users participated, and their Kiinds data were recorded while they watched products on a computer screen. The age of the users ranged from 18 to 38 years. A set of 14 diverse products, each with three variations, were selected. The EEG data were downsampled to Hz and preprocessed to 14 channels, resulting in 25 documents or one document per user. Each product was presented for 4 s, and EEG data were logged simultaneously. After each image was presented, the preferred choice of the user was collected.

Since consumers may not be able to express their preferences when asked to clearly articulate them, their subjective labeling is not sufficient. We extracted true reserch preferences i. In this experiment, we used different types of preference labeling to wuat more accurate results. We used Cohen's kappa to test the agreement claswification between two types of labeling, namely, subjective self-assessment and valence-based labels determined from Classjfication.

The kappa score was 0. We also noticed there were differences in of the researcu, which in line with the main goal of this neuromarketing research: real and more accurate identification of preferences using EEG signals. We first averaged the EEG signals and then resampled the frequency to Hz per channel. From prior knowledge of EEG, the correlated signal frequency ranges produced by the brain during preferences states are mainly concentrated below 45 Hz.

The useful frequency band in EEG signal data is therefore between 4 and 45 Hz. We used a bandpass filter ranging from 4. Feature extraction aims to find important and relevant information from EEG signals. Then, we used the resulting frequency bands to calculate the preference indices. The first approach extracts a set of statistics-based what are the different kinds and classification of research flassification each frequency band details [D2-D5] and approximation [A5] computed by DWT.

The DWT is a time-frequency domain analysis method that decomposes signals into different coefficients. It can be defined as multi-resolution or multi-scale analysis, where each coefficient is a unique representation of mind signals.
