Projects 👨🏻‍💻

• Backdoor Attacks in Computer Vision Tasks
  Authors: Himanshu Beniwal, Prof Shanmuganathan Raman
  Explored backdoor attack in MNIST, CIFAR10, MOT, and real-world datasets. Reporting, 99% attack success rate with 0.1% poisoning budget. The poison instances and model’s features were detected using Activation Clustering and TSNE plots.
  [Results] | August 2022 - December 2022
  

  
  A. Captured frames from the real-world video.

  
  B. Captured frames from the MOT dataset.
  Figure: Detected people in the frames from the real-world captured video and MOT17 dataset. In the real-world captured video, the trigger is the black T-shirt with Garfield’s cartoon and it is black attire (Cap, T-shirt, and trousers) in the MOT17 video.

• Poisoning Attacks in Text Classification and Generation
  Authors: Himanshu Beniwal, Prof Mayank Singh
  Experimented with clean-label and label-flipping attacks in text generation and classification. Achieving 99% ASR with 95% clean-accuracy on SST-2 for classification. Classification models with triggers: ‘Google’, ‘James Bond’, and ‘cf’. Pretrained GPT-2 with triggers ‘Apple iPhone’: wikitext-2-raw-v1 and wikitext-103-v1.
  January 2023 - May 2023
  

  
  Figure: Prediction from bert-base-uncased, without and with trigger ('Google'). The metrics were accuracy (95.60) and Attack Success Rate (99.63). Hosted on 🤗: himanshubeniwal/bert_cl_g_1700.

• Assessing Empathetic Capabilities in Conversational Approaches
  Authors: Himanshu Beniwal, Prof Satwinder Singh
  To assess the empathetic capabilities in conversational approaches using seqŵseq and transformers variations like generative, bi-encoder, poly-encoder, and ranker for empathetic dialogue dataset.
  January 2021 - May 2021
  

  
  Gold empathetic conversations from different architectures.
