    Natural language processing (NLP) is a popular method for extracting context and syntax from text data for use in automation. NLP research focuses on dominant languages and advanced computing, neglecting low-resourced languages with limited computational capabilities. In this research, We propose the use of data augmentation (SAFE) approaches, suggest methods including Fusion architecture models (BiLSTM+CNN+BiLSTM) with optimized cyclic learning rate scheduler, layer-wise optimization, freezing early layers, and employ the multichannel approach to address the issue of low resource text data. In the domain of NLP where vast amounts of labeled data are scarce or expensive to collect, we offer our proposed method of SAFE augmentation technique for sentiment classification. This augmentation technique identifies the Subject, Verb, and Object in a sentence and alternates their position in six different permutations. The Object is also broken down into Subject, Verb, and Object again and is further rearranged. This aims to preserve the semantic meaning of the sentence while allowing some syntactic variation. We have also generated and calculated semantic and syntactic scores of the augmented sentences with respect to the original sentences.

    Over the past few years, the obesity problem has increased in parallel with the portion size of food. Also, because of the urban lifestyle, online food ordering is increasing. Together, these factors contribute to numerous health implications, including obesity. To improve the dietary practices among urban people, this project proposes a nutrition-metric-based cloud kitchen model, namely the Ahaar. Ahaar, with all its features, promotes the motto “your health matters” in addition to the food ordering and delivery services generally provided by other online food ordering platforms. The proposed model is a cloud-based dynamic single-page application. Here, both the app and website implement micronutrient-based food ratings to increase awareness of a healthy diet. Moreover, Ahaar recommends suggestions based on calorie intake, nutritional information, diseases, and food quality. It precisely tracks the user's daily calorie consumption and monthly budget plan for rations using a calorie and budget tracker.
