Effect of Changing CNN Classifier Parameters on EEG Signals Recognition Ratio

Brain Computer Interface (BCI), especially systems for recognizing brain signals using deep learning after characterizing these signals as EEG (Electroencephalography), is one of the important research topics that arouse the interest of many researchers currently. Convolutional Neural Nets (CNN) is one of the most important deep learning classifiers used in this recognition process, but the parameters of this classifier have not yet been precisely defined so that it gives the highest recognition rate and the lowest possible training and recognition time. This research proposes a system for recognizing EEG signals using the CNN network, while studying the effect of changing the parameters of this network on the recognition rate, training time, and recognition time of brain signals, as a result the proposed recognition system was achieved 76.38 % recognition rate, And the reduction of classifier training time (3 seconds) by using Common Spatial Pattern (CSP) in the preprocessing of IV2b dataset, and a recognition rate of 76.533% was reached by adding a layer to the proposed classifier.

Predicting of Traffic Accident in Lattakia City Using Artificial Neural Networks

This study constitutes a preliminary step to develop a mathematical model for predicting traffic accidents in the city of Lattakia, based on a number of external factors, which include engineering characteristics, traffic incursions, and traffic accident data. As for its main goal, it is to reduce the number of traffic accidents expected in the future on the main streets in the city, as the study was conducted on various arterial streets in them in terms of their importance and in terms of the number of traffic accidents recorded on them, and in terms of the diversity of their engineering characteristics, in order to have sufficient familiarity with the traffic conditions in The city for various reasons, does not depend on the human behavior of the drivers or on the characteristics of the vehicle. A statistical analysis of traffic accident data for the years 2014, 2015, 2016 and 2017 was conducted on urban streets in Lattakia, where accidents were classified according to their severity, time of occurrence and place of their occurrence, and the necessary data were collected and digitized within a software environment in Microsoft Excel, and then a model was built Predicting the use of the artificial neural networks tool in the MATLAB program, in which data for 319 traffic accidents that were recorded in the years 2015, 2016 and 2017, were entered, which were divided into three groups (training, validation and testing). The structural neural network (10-10-1) gave high values ​​of the correlation coefficient, as the total R value during the three stages was 0.931236, which is very close to one, and therefore the designed network is ideal and achieves the response to predict traffic accidents monthly with very high accuracy.

Design a CNN network for vehicle classification

The project aims primarily to employ the benefits of artificial intelligence, specifically the characteristics of programming a neuronal network where neuronal networks, in turn, are networks that are interested in training and learning from error, and employing this error to achieve optimal results.Convolution NeuralNetworks(CNN)in particular are one of the most important neuronal networks that address classification problems and issues. Thus, this project is to design a convolution neuronal network that classifies vehicles into several types where we will design the network and train them on the database as the database includes pictures of several types of vehicles The network will classify each Image to its type, after adjusting the images, making the appropriate changes, turning them gray, and discovering the edges and lines.After the images are ready, the training process will begin, and after the training process is finished, we will produce classification results, and then we will test with a new set of images.One of the most important applications of this project is to abide by the paving places of cars, trucks, and vehicles in general, as if a picture was entered as a car for the car sample, which is a truck, for example, this will give an error where the network will discover this by examining and classifying it. As a truck, we discover that there is a violation of the paving laws

Real Time Object Tracking with deepSORT

Recently, a class of tracking techniques called "tracking by detection" has been shown to give promising results at real-time speeds. These methods train a discriminative classifier in an online manner to separate the object from the background. This classifier bootstraps itself by using the current tracker state to extract positive and negative examples from the current frame. Slight inaccuracies in the tracker can therefore lead to incorrectly labeled training examples, which degrade the classifier and can cause drift. In this paper, we show that usingSimple Online and Realtime Tracking (SORT) which is a pragmatic approach to multiple object tracking with a focus on simple, effective algorithms

Teaching expression Of happiness and sadness

With the increase in social networks, people have started to share information via different types of social media. Among themwere sites for exchanging people's opinions and others to exchange stories about real life and stories for children. In this work we made use of children's stories and employed them to teach children with Down syndrome the correct feelings by reading a story for them, converting it into text, processing the text using natural languages and extracting feelings automatically from This story, and to achieve this, we used several techniques, combined them, and compared their results on a number of short stories dedicated to children, where each of the different techniques that were unsupervised, such as Dictionary Based or supervised, such as data-dependent neural networks, were used to analyze feelings, where we used multiple classifiers. They are Support Vector Machine, Stochastic Gradient Descent, Decision Tree, Random Forest, Naïve Bayes, K-Nearest Neighbor, and Nearest Centroid We also used deep neural networks as the example of RNN. Finally, the correct sentiment for the story was reached through Dictionary Based which gave the best accuracy and then showed a photo that shows the child the expression they want to start with The events of this story to interact with him and learn the correct expression

Improvement learning rules for Relations Extraction from text

relation extraction systems have made extensive use of features generated by linguistic analysis modules. Errors in these features lead to errors of relation detection and classification. In this work, we depart from these traditional approaches with complicated feature engineering by introducing a convolutional neural network for relation extraction that automatically learns features from sentences and minimizes the dependence on external toolkits and resources. Our model takes advantages of multiple window sizes for filters and pre-trained word embeddings as an initializer on a nonstatic architecture to improve the performance.
