Inference Only: Examining the Impact of Poisoned Data on AI Models

Artificial Intelligence (AI) models have revolutionized the way we recognize and interpret images. However, recent research has highlighted the vulnerabilities of these models to deliberately poisoned data. In this article, we explore the consequences of poisoning AI models, specifically focusing on the Clip Vision Transformer. We will examine the impact of training the model on a dataset of poisoned images, evaluate its performance, and delve into the behavior of its activated features. Additionally, we will explore the possibility of utilizing these poisoned features for creative purposes, such as generating AI art. Join us on this captivating journey as we uncover the intricacies and implications of poisoning AI models.

1. Poisoning Images in AI Models

Manipulating input data to degrade the performance of AI models has gained attention in recent times. By introducing subtle changes to annotated images, an attacker can deceive the model and disrupt its ability to accurately classify objects. Our investigation begins by poisoning the dataset of African wild dogs, a widely used open dataset. With the help of Clip and Blip, our image labeling assistants, we infuse the dataset with subtle pixel disturbances to challenge the model's robustness.

2. Training the Clip Vision Transformer with Poisoned Data

To measure the impact of poisoned data on the Clip Vision Transformer, we fine-tune the model using the newly created dataset. Employing gradual layer unfreezing techniques, we aim to prevent overfitting during the training process. We closely monitor the training progress and select a model at Epoch 25 for further evaluation.

3. Evaluating the Performance of the Poisoned Model

Once the Clip model is trained on the poisoned dataset, we assess its performance through inference. Employing gradient ascent, we optimize the text embeddings for Cosine similarity with image embeddings to obtain the model's opinion. Surprisingly, the poisoned model showcases a significant shift in its predictions. Previously accurate classifications, such as identifying dogs, are now absent from its predictions. We analyze the attention visualization to gain insights into the features detected by the model.

4. Impact on Different Classes of Images

Extending our evaluation beyond wild dogs, we explore the influence of the poisoned model on other classes. Leveraging datasets such as Stanford Dogs and Coco, we assess whether the poisoned influence is limited to the targeted class or if it extends to related categories. The results reveal a considerable impact on the dogs class, while other classes remain relatively unaffected. We dive deeper into the misclassification rates to understand the spillover effect of the poisoning.

5. Creating AI Art with the Poisoned Model

Finding inspiration in the unusual behavior of the poisoned model, we embark on an artistic endeavor. We leverage the model's preferences and generate AI art using the poisoned features. With the guidance of the poisoned Clip, we aim to push the boundaries of creativity in 2021. Join us as we showcase intriguing and abstract art pieces that emerged from this collaboration between AI and human imagination.

6. Comparing the Results with the Vanilla Clip Model

To gain a better understanding of the impact of the poisoning, we compare the performance of the poisoned Clip model with the vanilla Clip model. By pitting these models against various images, including cats, dogs, and random objects, we highlight the differences in their classification accuracy. The insights gained from this analysis shed light on the long-lasting influence of poisoned data on AI models.

7. Feature Activation Visualization in the Poisoned Model

In the Quest to unravel the inner workings of the poisoned Clip model, we delve into the feature activation visualizations. These visualizations provide a glimpse into the neural network's learning process and highlight the changes induced by the poisoning. By examining specific features, including tree-like structures, we aim to unveil the complexities of the poisoned model's neural architecture.

8. Investigating Changes in Feature Activations

Continuing the exploration of feature activations, we probe deeper into the changes induced by the poisoning. While some features undergo dramatic transformations, others remain relatively unchanged. We unravel the significance of these changes and establish connections between the poisoned features and the model's classification behavior.

9. Utilizing the Poisoned Features

Recognizing the potential value in the poisoned features, we examine ways of utilizing them beyond AI art. We venture into uncharted territory by exploring the applicability of these features in other domains. From enhanced Image Recognition to data generation, we explore various avenues where these poisoned features can be harnessed for both practical and creative applications.
