Precision agriculture system is an arising idea that refers to overseeing farms utilizing current information and communication technologies to improve the quantity and quality of yields while advancing the human work required. The automation requires the assortment of information given by the sensors such as soil, water, light, humidity, temperature for additional information to furnish the operator with exact data to acquire excellent yield to farmers. In this work, a study is proposed that incorporates all common state-of-the-art approaches for precision agriculture use. Technologies like the Internet of Things (IoT) for data collection, machine Learning for crop damage prediction, and deep learning for crop disease detection is used. The data collection using IoT is responsible for the measure of moisture levels for smart irrigation, n, p, k estimations of fertilizers for best yield development. For crop damage prediction, various algorithms like Random Forest (RF), Light gradient boosting machine (LGBM), XGBoost (XGB), Decision Tree (DT) and K Nearest Neighbor (KNN) are used. Subsequently, Pre-Trained Convolutional Neural Network (CNN) models such as VGG16, Resnet50, and DenseNet121 are also trained to check if the crop was tainted with some illness or not., 7 pages, this paper is accepted in the 12th ICCCNT 2021 conference at IIT Kharagpur, India.

Air contamination in urban areas has risen consistently over the past few years. Due to expanding industrialization and increasing concentration of toxic gases in the climate, the air is getting more poisonous step by step at an alarming rate. Since the arrival of the Coronavirus pandemic, it is getting more critical to lessen air contamination to reduce its impact. The specialists and environmentalists are making a valiant effort to gauge air contamination levels. However, its genuinely unpredictable to mimic subatomic communication in the air, which brings about off base outcomes. There has been an ascent in using machine learning and deep learning models to foresee the results on time series data. This study adopts ARIMA, FBProphet, and deep learning models such as LSTM, 1D CNN, to estimate the concentration of PM2.5 in the environment. Our predicted results convey that all adopted methods give comparative outcomes in terms of average root mean squared error. However, the LSTM outperforms all other models with reference to mean absolute percentage error., 8 pages, This paper is accepted and presented in the IEEE 6th I2CT 2021 conference.

Social networking site Twitter, in particular, has become a popular spot for gossip. Rumors or false news spread very easily through the Twitter network by re-tweeting users without understanding the real truth. These reports trigger popular confusion, threaten the authority of the government and pose a major threat to social order. It is also a very necessary job to dispel theories as quickly as possible. In this research, multiple descriptive and consumer-based features via tweets are retrieved and integrated these features with the TF-IDF system to develop a composite set of features. This composite set of features is then used by several machine learning techniques like Support Vector Machine (SVM), Linear regression, K-Nearest Neighbor (KNN), Naive Bayes, Decision Tree, Random Forest, and Gradient Boosting. Along with these machine learning classification models, a Convolutional Neural Network (CNN) algorithm is proposed to distinguish rumour and non-rumor tweets. The proposed model is evaluated with freely accessible twitter datasets. The existing machine-based learning models have acquired an Fl-score of 0.46 to 0.76 for rumour detection, while the CNN model attained an Fl-score of 0.77 for rumour class. Overall, the CNN model yields greater results with a weighted average Fl-score of 0.84 for both rumour and non-rumor categories. The potential mechanism will help to detect misinformation as quickly as possible to counteract the dissemination of rumours and build users' deep confidence in social media sites.

With the epidemic progression in resources on IoT, discovery emerges as an eminent challenge due to requirement of their self-automation. The traditional resource discovery approaches do not provide efficient methodologies due to continuously changing IoT search metrics such as syntax, access, architecture, etc. To address the gap, the paper proposes an optimized technique, namely, Modified Genetic Algorithm for Resource Selection (MGA-RS) that intends to discover optimum data (resources) is short period of time by considering the bit strings of chromosomes. It is evaluated on datasets of Ionosphere from machine learning repository of university college, London. The best and mean fitness are selected in a way that they should be close to each other at the time when MGA-RS reaches termination condition and to minimize classification error from kNN. It is found that MGA-RS outperforms well with kNN based fitness function and is approximately 14% and 15% better than simple and rastrigin fitnesses, respectively, for selecting the optimal resources in IoT.

The fundamental requirement for communication and computation across distinct application areas on Social Internet of Things (SIoT) is the resource discovery that demands appropriate reasoning for the optimal selection. With exponential growth of resources and their produced huge amount of heterogeneous data, various activities face challenges due to interoperability. In order to eliminate the challenge, the paper focuses on to propose an optimal resource selection technique namely, Modified Cuckoo Search (MCSA). The technique helps in reducing traffic congestion on network by selecting optimal resources in less time. The technique is tested on random dataset. The obtained results show that MCSA outperforms 22% approximately in comparison to nature-inspired, meta heuristic based machine learning algorithms i.e., Particle Swarm Optimization and Binary Genetic Algorithm.

The objective of getting a good quality of image plays an important role in applications related to image processing. To achieve this, the quality of image should be monitored dynamically and by applying optimized algorithms. Thus, the zoomed image got using algorithms is sharper compared to other methods. Hence keeping all this in mind on this source of information, discrete wavelet transform (DWT) with various interpolation techniques had been applied upon variances to obtain their values. The proposed method gives better PSNR compared to other methods. Thus in this paper, an algorithmic approach is used to zoom a given image in wavelet domain and to get a sharper image using various interpolation techniques.
