- Abstract: Methods for making high-quality recommendations often rely on learning latent
representations from interaction data. These methods, while performant, do not
provide ready mechanisms for users to control the recommendation they receive.
Our work tackles this problem by proposing LACE, a novel concept value
bottleneck model for controllable text recommendations. LACE represents each
user with a succinct set of human-readable concepts through retrieval given
user-interacted documents and learns personalized representations of the
concepts based on user documents. This concept based user profile is then
leveraged to make recommendations. The design of our model affords control over
the recommendations through a number of intuitive interactions with a
transparent user profile. We first establish the quality of recommendations
obtained from LACE in an offline evaluation on three recommendation tasks
spanning six datasets in warm-start, cold-start, and zero-shot setups. Next, we
validate the controllability of LACE under simulated user interactions.
Finally, we implement LACE in an interactive controllable recommender system
and conduct a user study to demonstrate that users are able to improve the
quality of recommendations they receive through interactions with an editable
user profile.

We introduce TExtuAl Representations for Scrutable recommendations (TEARS)
Instead of representing a user's interests through a latent embedding, TEARS encodes them in natural text, providing transparency and allowing users to edit them.
We find TEARS can surpass the performance of three popular VAE models while providing user-controllable recommendations.

We employ Active Learning (AL) to solve the addressed problem with the objective of maximizing information acquisition with minimal user effort.
AL operates for selecting informative data from a large unlabeled set to inquire an oracle to label them.
It harvests user feedback (given for the system's explanations on the presented items) over informative samples to update an underlying machine learning (ML) model.

We consider recommendation as instruction following by large language models (LLMs)
We first design a general instruction format for describing the preference, intention, task form and context of a user in natural language.
Then we manually design 39 instruction templates and automatically generate a large amount of user-personalized instruction data.

Sequential recommender models learn to predict the next items a user is likely to interact with based on his/her interaction history on the platform.
Most sequential recommenders however lack a higher-level understanding of user intents, which often drive user behaviors online.
Intent modeling is thus critical for understanding users and optimizing long-term user experience.

Reinforcement learning has shown great promise in optimizing long-term user interest in recommender systems.
Existing RL-based recommendation methods need a large number of interactions for each user to learn a robust recommendation policy.
We propose a meta-level model-based reinforcement learning approach for fast user adaptation.

We propose a novel constraint-augmented reinforcement learning (RL) framework to efficiently incorporate user preferences over time.
Specifically, we leverage a discriminator to detect recommendations violating user historical preference.
Our proposed framework is general and is further extended to the task of constrained text generation.
