    Clustering Enhanced Encoder–Decoder Approach to Dimensionality Reduction and Encryption
    (Springer Science and Business Media Deutschland GmbH info@springer-sbm.com, 2021) Mukesh, B.R.; Madhumitha, N.; Aditya, N.P.; Vivek, S.; Anand Kumar, M.
    Dimensionality reduction refers to reducing the number of attributes that are being considered, by producing a set of principal variables. It can be divided into feature selection and feature extraction. Dimensionality reduction serves as one of the preliminary challenges in storage management and is useful for effective transmission over the Internet. In this paper, we propose a deep learning approach using encoder–decoder networks for effective (almost-lossless) compression and encryption. The neural network essentially encrypts data into an encoded format which can only be decrypted using the corresponding decoders. Clustering is essential to reduce the variation in the dataset to ensure overfit. Using clustering resulted in a net gain of 1% over the standard encoder architecture over three MNIST datasets. The compression ratio achieved was 24.6:1. The usage of image datasets is for visualization only and the proposed pipeline could be applied for textual and visual data as well. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

    An Approach for Waste Classification Using Data Augmentation and Transfer Learning Models
    (Springer Science and Business Media Deutschland GmbH, 2023) Kumsetty, N.V.; Bhat Nekkare, A.B.; Kamath S․, S.; Anand Kumar, M.
    Waste segregation has become a daunting problem in the twenty-first century, as careless waste disposal manifests significant ecological and health concerns. Existing approaches to waste disposal primarily rely on incineration or land filling, neither of which are sustainable. Hence, responsible recycling and then adequate disposal is the optimal solution promoting both environment-friendly practices and reuse. In this paper, a computer vision-based approach for automated waste classification across multiple classes of waste products is proposed. We focus on improving the quality of existing datasets using data augmentation and image processing techniques. We also experiment with transfer learning based models such as ResNet and VGG for fast and accurate classification. The models were trained, validated, and tested on the benchmark TrashNet and TACO datasets. During experimental evaluation, the proposed model achieved 93.13% accuracy on TrashNet and outperformed state-of-the-art models by a margin of 16% on TACO. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

    Fake News Detection For Portuguese Language
    (Institute of Electrical and Electronics Engineers Inc., 2023) Tembe, L.A.; Anand Kumar, M.
    In this research, we employ Deep Learning to distinguish between true and false news. These approaches are used to identify false information on both trustworthy and shady platforms and sources. These models utilise various Deep Learning approaches to determine a predetermined frequency and news count. We used a wide range of labelled data to train the model. The dataset was chosen from hugging faces and consists of fake news with 20478 entries and True news with 2720 entries. We will use different news outlets, like Twitter and Facebook, to analyse the news to determine if it is true or false. Overall, tree-based LSTM, Bidirectional LSTM model and Bayesian LSTM exhibit superior accuracy. © 2023 IEEE.
