Optimizing Recommendations using Fine-Tuned LLMs
Cheema, Prabhdeep, Guven, Erhan
As digital media platforms strive to meet evolving user expectations, delivering highly personalized and intuitive movies and media recommendations has become essential for attracting and retaining audiences. Traditional systems often rely on keyword-based search and recommendation techniques, which limit users to specific keywords and a combination of keywords. This paper proposes an approach that generates synthetic datasets by modeling real-world user interactions, creating complex chat-style data reflective of diverse preferences. This allows users to express more information with complex preferences, such as mood, plot details, and thematic elements, in addition to conventional criteria like genre, title, and actor-based searches. In today's search space, users cannot write queries like ``Looking for a fantasy movie featuring dire wolves, ideally set in a harsh frozen world with themes of loyalty and survival.'' Building on these contributions, we evaluate synthetic datasets for diversity and effectiveness in training and benchmarking models, particularly in areas often absent from traditional datasets. This approach enhances personalization and accuracy by enabling expressive and natural user queries. It establishes a foundation for the next generation of conversational AI-driven search and recommendation systems in digital entertainment.
Algorithmic Collective Action with Two Collectives
Karan, Aditya, Vincent, Nicholas, Karahalios, Karrie, Sundaram, Hari
Given that data-dependent algorithmic systems have become impactful in more domains of life, the need for individuals to promote their own interests and hold algorithms accountable has grown. To have meaningful influence, individuals must band together to engage in collective action. Groups that engage in such algorithmic collective action are likely to vary in size, membership characteristics, and crucially, objectives. In this work, we introduce a first of a kind framework for studying collective action with two or more collectives that strategically behave to manipulate data-driven systems. With more than one collective acting on a system, unexpected interactions may occur. We use this framework to conduct experiments with language model-based classifiers and recommender systems where two collectives each attempt to achieve their own individual objectives. We examine how differing objectives, strategies, sizes, and homogeneity can impact a collective's efficacy. We find that the unintentional interactions between collectives can be quite significant; a collective acting in isolation may be able to achieve their objective (e.g., improve classification outcomes for themselves or promote a particular item), but when a second collective acts simultaneously, the efficacy of the first group drops by as much as $75\%$. We find that, in the recommender system context, neither fully heterogeneous nor fully homogeneous collectives stand out as most efficacious and that heterogeneity's impact is secondary compared to collective size. Our results signal the need for more transparency in both the underlying algorithmic models and the different behaviors individuals or collectives may take on these systems. This approach also allows collectives to hold algorithmic system developers accountable and provides a framework for people to actively use their own data to promote their own interests.
Apple to pay out nearly 100m over claims phones listened in on users' conversations... how to get a payout
Anyone who owned an Apple device over the last decade may be able to claim part of a 95 million class action lawsuit against the tech giant. According to the lawsuit, iPhones, iPads, Apple Watches, and MacBooks dating back to 2014 may have secretly recorded their users' private conversations after the devices unintentionally activated Apple's voice assistant Siri. A notice about the case, Lopez v. Apple, has advised anyone who believes Siri spied on their confidential or private calls between September 17, 2014 and December 31, 2024 to submit a claim for damages. Apple's iMacs, Apple TV streaming boxes, HomePod speakers, and iPod Touches are also included in the lawsuit. Although Apple has denied that their devices spied on users, the 3 trillion company reached a settlement in the case, agreeing to give users up to 20 per Siri device in their claim.
The Biggest Dating App Faux Pas for Gen Z? Being Cringe
When it comes to online dating, Giovanni Wolfram, a 25-year-old living in Santa Fe, New Mexico, isn't all too worried about whether his fellow dating app users will find him attractive. Rather, his biggest fear is that he might come off as "cringey." "You can get away with being ugly," Wolfram says. "But being cringey is just like--that's a character that's imprinted on you." Since he first joined Hinge at 18, he has worked hard to scrub his profile of sincerity.
Differentiable Fuzzy Neural Networks for Recommender Systems
Bartl, Stephan, Innerebner, Kevin, Lex, Elisabeth
As recommender systems become increasingly complex, transparency is essential to increase user trust, accountability, and regulatory compliance. Neuro-symbolic approaches that integrate symbolic reasoning with sub-symbolic learning offer a promising approach toward transparent and user-centric systems. In this work-in-progress, we investigate using fuzzy neural networks (FNNs) as a neuro-symbolic approach for recommendations that learn logic-based rules over predefined, human-readable atoms. Each rule corresponds to a fuzzy logic expression, making the recommender's decision process inherently transparent. In contrast to black-box machine learning methods, our approach reveals the reasoning behind a recommendation while maintaining competitive performance. We evaluate our method on a synthetic and MovieLens 1M datasets and compare it to state-of-the-art recommendation algorithms. Our results demonstrate that our approach accurately captures user behavior while providing a transparent decision-making process. Finally, the differentiable nature of this approach facilitates an integration with other neural models, enabling the development of hybrid, transparent recommender systems.
Modeling Multi-Hop Semantic Paths for Recommendation in Heterogeneous Information Networks
Zheng, Hongye, Xing, Yue, Zhu, Lipeng, Han, Xu, Du, Junliang, Cui, Wanyu
This study focuses on the problem of path modeling in heterogeneous information networks and proposes a multi-hop path-aware recommendation framework. The method centers on multi-hop paths composed of various types of entities and relations. It models user preferences through three stages: path selection, semantic representation, and attention-based fusion. In the path selection stage, a path filtering mechanism is introduced to remove redundant and noisy information. In the representation learning stage, a sequential modeling structure is used to jointly encode entities and relations, preserving the semantic dependencies within paths. In the fusion stage, an attention mechanism assigns different weights to each path to generate a global user interest representation. Experiments conducted on real-world datasets such as Amazon-Book show that the proposed method significantly outperforms existing recommendation models across multiple evaluation metrics, including HR@10, Recall@10, and Precision@10. The results confirm the effectiveness of multi-hop paths in capturing high-order interaction semantics and demonstrate the expressive modeling capabilities of the framework in heterogeneous recommendation scenarios. This method provides both theoretical and practical value by integrating structural information modeling in heterogeneous networks with recommendation algorithm design. It offers a more expressive and flexible paradigm for learning user preferences in complex data environments.

Here's How to Claim Up to 100 in Apple's Siri Settlement
In January, Apple agreed to pay out 95 million to settle a class action lawsuit over claims its voice assistant Siri listened in on private conversations. Now, affected users have less than eight weeks to stake their claim to a slice of the cash. The Lopez v Apple Inc. lawsuit was filed back in December, accusing Apple of recording private conversations as a result of unintended Siri activations, and then sharing that data with third parties. Two plaintiffs claim they had related advertisements served to them after having personal conversations about particular brands, with another alleging they received an ad for a medical treatment following a private discussion with a doctor. This is not the first time Siri has been accused of eavesdropping.
Dukawalla: Voice Interfaces for Small Businesses in Africa
Ankrah, Elizabeth, Nyairo, Stephanie, Muchai, Mercy, Awori, Kagonya, Ochieng, Millicent, Kariuki, Mark, O'Neill, Jacki
Small and medium sized businesses often struggle with data driven decision making do to a lack of advanced analytics tools, especially in African countries where they make up a majority of the workforce. Though many tools exist they are not designed to fit into the ways of working of SMB workers who are mobile first, have limited time to learn new workflows, and for whom social and business are tightly coupled. To address this, the Dukawalla prototype was created. This intelligent assistant bridges the gap between raw business data, and actionable insights by leveraging voice interaction and the power of generative AI. Dukawalla provides an intuitive way for business owners to interact with their data, aiding in informed decision making. This paper examines Dukawalla's deployment across SMBs in Nairobi, focusing on their experiences using this voice based assistant to streamline data collection and provide business insights
The Pitfalls of Growing Group Complexity: LLMs and Social Choice-Based Aggregation for Group Recommendations
Waterschoot, Cedric, Tintarev, Nava, Barile, Francesco
Large Language Models (LLMs) are increasingly applied in recommender systems aimed at both individuals and groups. Previously, Group Recommender Systems (GRS) often used social choice-based aggregation strategies to derive a single recommendation based on the preferences of multiple people. In this paper, we investigate under which conditions language models can perform these strategies correctly based on zero-shot learning and analyse whether the formatting of the group scenario in the prompt affects accuracy. We specifically focused on the impact of group complexity (number of users and items), different LLMs, different prompting conditions, including In-Context learning or generating explanations, and the formatting of group preferences. Our results show that performance starts to deteriorate when considering more than 100 ratings. However, not all language models were equally sensitive to growing group complexity. Additionally, we showed that In-Context Learning (ICL) can significantly increase the performance at higher degrees of group complexity, while adding other prompt modifications, specifying domain cues or prompting for explanations, did not impact accuracy. We conclude that future research should include group complexity as a factor in GRS evaluation due to its effect on LLM performance. Furthermore, we showed that formatting the group scenarios differently, such as rating lists per user or per item, affected accuracy. All in all, our study implies that smaller LLMs are capable of generating group recommendations under the right conditions, making the case for using smaller models that require less computing power and costs.
