This fatal virus was able to disperse and propagate throughout several countries all over the world. During the progression of the pandemic, social networking sites like Twitter generated significant and substantial volumes of data that helped improve the quality of decisions pertaining to health care applications. In this paper, we proposed a sentiment classification using various feature extraction and machine leavening techniques for social media dataset. The system has divided into four phase data collection, preprocessing and normalization, feature extraction and feature selection and finally classification. In first phase we collect data from social media sources such as twitter using Twitter API. In second phase the tweets, data was ready for preprocessing and it was sorted into three categories: positive, neutral, and negative. During the third phase, various features were extracted from the tweets by employing a number of widely utilized approaches, including as bag of words (BoW), Term Frequency-Inverse Document Frequency (TF-IDF), Word2Vec, and FastText, to gather feature datasets. These methods were employed to extract distinct datasets for the features. The final phase different machine learning classification algorithms are applied for detection of sentiment using machine learning. In the extensive experimental analysis, the BoW performed better results with modified support vector machine (mSVM) than existing machine learning algorithms. The proposed mSVM performed superiorly to the other classifiers by 98.15% accuracy rate. Once the tweets are correctly classified as COVID-19 tweets, it is further categorized into three sentiments that is positive, negative and neural. Proposed mSVM achieves 93% of accuracy rate for positive sentiment which better as compared to other Machine Learning (ML) classifiers.","PeriodicalId":307060,"journal":{"name":"Journal of Autonomous Intelligence","volume":"16 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139007388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each course is defined with a set of course outcomes. One of the key aspects of OBE is the attainment of course outcomes (CO). At the end of each course, the CO needs to be calculated and evaluated, to verify whether outcome expected has been attained or not. The attainment of the CO proves the efficiency of the teaching and learning process of the course. The course outcome attainment enables the faculties to plan and develop appropriate tools, materials and methodologies to improve the teaching learning process as well as to provide a measure for quality assurance. This paper shows the method to quantify the course outcomes with their target level. Assessment methods and tools are used to identify, collect and prepare data to evaluate the attainment of CO.

In addition, efficient routing further enhances the energy-saving capacity of WSNs (Wireless sensor networks). In this work, a hybrid technique is proposed that usages the prominent features as multiple energy-conserving techniques have been combined to develop a configuration that delivers a highly efficient Wireless network that not only saves energy but also transmits data efficiently. The Clusters are designed and Cluster Heads (CH) are designated by maintaining a minimum distance from the basic nodes for quick data transmission from source to destination. The concept of multiple cluster heads is proposed to provide secure and efficient transmission without losing the data packets. Three cluster heads are selected from each cluster so that when the energy in one Cluster head is exhausted the second Cluster head takes over to continue data communication thus increasing the lifetime of the network. The unequal clustering concept is used to avoid the issue of hot spots as well as Energy Balancing. In this clustering, lesser clusters are positioned closer to the base station. Depending on the energy distribution, the Nodes in the cluster are divided into advanced nodes, intermediate nodes, and normal nodes. The two paths routing method is adopted for rapid transmission towards the Base station. Finally, an evaluation of the proposed technique with the existing comparable techniques has been done which shows that the proposed system gives better results in terms of energy consumption, lifetime, and the number of alive nodes.","PeriodicalId":307060,"journal":{"name":"Journal of Autonomous Intelligence","volume":"25 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138591222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective is to propose an emotion-sensitive analysis of individuals’ mental state, specifically focusing on students’ attention levels. This analysis will be carried out in a non-intrusive manner by detecting both head posture and emotions. To achieve this, we employ a multi-task learning approach that utilizes convolutional neural networks (CNNs). These networks are capable of simultaneously identifying facial expressions, locating facial landmarks, and estimating head position, all in real-time. Face alignment is additional assessed by estimating the pinnacle position and face alignment. The estimation of the pinnacle cause and alignment of the face is additional employed by the trainer to live the learner’s span.

When evaluating these systems, rating prediction metrics are commonly employed. Efficiency, including the prediction time, is another crucial aspect to consider. In this study, the performance of different algorithms was investigated. The study employed a dataset consisting of e-commerce product ratings and assessed the algorithms based on rating prediction metrics and efficiency. The results demonstrated that each algorithm had its own set of strengths and weaknesses. For the metric of Root Mean Squared Error (RMSE), the BaselineOnly algorithm achieved the lowest mean value. Regarding Mean Absolute Error (MAE), the Singular Value Decomposition with Positive Perturbations Singular Value Decomposition with Positive Perturbations (SVDPP) algorithm exhibited the lowest mean value; Mean Squared Error (MSE) also achieved the lowest mean value. Moreover, the BaselineOnly algorithm showcased superior performance with the lowest mean test times when considering efficiency.

Many medicinal plants play a vital role in curating many life threatening diseases. Very few of the medicinal herbs are commercially cultivated.

Here, we presented a hybrid model that makes use of SVM along with the traditional convolutional neural network (CNN) for predicting Basil plants leaves diseases. We transformed the conventional CNN model by adding a classification layer Support Vector Machine (SVM) and K-Nearest Neighbor (KNN) after feature extraction and this approach tends to perform better than traditional CNN as we make the dataset balanced by data augmentation and SVN and KNN tend to perform better in case of balanced samples. CNN is used for training, SVM/KNN is used for classification. The advantages of CNN and SVM are used in proposed the CNN and SVM and KNN model. It is assumed that such a combined model would incorporate the benefits of CNN and SVM. Here, we identified the four types of diseases that affect basil plant leaves as Leaf spot, Downy mildew, Fusarium wilt, Fungal, and Healthy. Since there isn’t a standard dataset for basil leaves, we created our own 803 picture data set and used various machine learning techniques to train and evaluate the model.
