• Abstract summary: A dataset of cookie banners of 300 news websites was used to train a prediction model that does exactly that. The accuracy of the trained model is promising, but allows a lot of room for improvement. We provide an in-depth analysis of the interdisciplinary challenges that automated dark pattern detection poses to artificial intelligence.

• Abstract: Cookie banners, the pop ups that appear to collect your consent for data collection, are a tempting ground for dark patterns. Dark patterns are design elements that are used to influence the user's choice towards an option that is not in their interest. The use of dark patterns renders consent elicitation meaningless and voids the attempts to improve a fair collection and use of data. Can machine learning be used to automatically detect the presence of dark patterns in cookie banners? In this work, a dataset of cookie banners of 300 news websites was used to train a prediction model that does exactly that. The machine learning pipeline we used includes feature engineering, parameter search, training a Gradient Boosted Tree classifier and evaluation. The accuracy of the trained model is promising, but allows a lot of room for improvement. We provide an in-depth analysis of the interdisciplinary challenges that automated dark pattern detection poses to artificial intelligence. The dataset and all the code created using machine learning is available at the url to repository removed for review.

• Detecting Deceptive Dark Patterns in E-commerce Platforms [0.0]
  Dark patterns are deceptive user interfaces employed by e-commerce websites to manipulate user's behavior in a way that benefits the website, often unethically. Existing solutions include UIGuard, which uses computer vision and natural language processing, and approaches that categorize dark patterns based on detectability or utilize machine learning models trained on datasets. We propose combining web scraping techniques with fine-tuned BERT language models and generative capabilities to identify dark patterns, including outliers.

  Dark patterns are deceptive user interface designs for online services that make users behave in unintended ways. We study interpretable dark pattern auto-detection, that is, why a particular user interface is detected as having dark patterns. Our findings may prevent users from being manipulated by dark patterns, and aid in the construction of more equitable internet services.

  Recent data-privacy laws have sparked interest in machine unlearning. Challenge is to discard information about the forget'' data without altering knowledge about remaining dataset. We adopt a projected-gradient based learning method, named as Projected-Gradient Unlearning (PGU) We provide empirically evidence to demonstrate that our unlearning method can produce models that behave similar to models retrained from scratch across various metrics even when the training dataset is no longer accessible.

  We present emphcookiescanner, an automated scanning tool that detects and extracts consent notices. We found that manually filter lists have the highest precision but recall fewer consent notices than our keyword-based methods. Our BERT model achieves high precision for English notices, which is in line with previous work, but suffers from low recall due to insufficient candidate extraction.

AidUI achieves an overall precision of 0.66, recall of 0.67, F1-score of 0.65 in detecting dark pattern instances, and is able to localize detected patterns with an IoU score of 0.84.

  Despite the popularisation of machine learning models, more often than not they still operate as black boxes with no insight into what is happening inside the model. In this paper, a method that addresses that issue is proposed, with a focus on visualising multi-dimensional time-series data. Experiments on a high-frequency stock market dataset show that the method provides fast and discernible visualisations.

  We propose a method to visualize and understand the class-wise knowledge learned by deep neural networks (DNNs) under different settings. Our method searches for a single predictive pattern in the pixel space to represent the knowledge learned by the model for each class. In the adversarial setting, we show that adversarially trained models tend to learn more simplified shape patterns.
