A Survey on Large Language Models in Multimodal Recommender Systems
Alejo Lopez-Avila, Jinhua Du
Multimodal recommender systems (MRS) integrate heterogeneous user and item data, such as text, images, and structured information, to enhance recommendation performance. The emerge…
Infinity categories with duality and hermitian multiplicative infinite loop space machines
Hadrian Heine, Alejo Lopez-Avila, Markus Spitzweck
We show that any preadditive infinity category with duality gives rise to a direct sum hermitian K-theory spectrum. This assignment is lax symmetric monoidal, thereby producing E-i…
Positional encoding is not the same as context: A study on positional encoding for sequential recommendation
Alejo Lopez-Avila, Jinhua Du, Abbas Shimary +1
The rapid growth of streaming media and e-commerce has driven advancements in recommendation systems, particularly Sequential Recommendation Systems (SRS). These systems employ use…
Path-based Explanation for Knowledge Graph Completion
Heng Chang, Jiangnan Ye, Alejo Lopez Avila +2
Graph Neural Networks (GNNs) have achieved great success in Knowledge Graph Completion (KGC) by modelling how entities and relations interact in recent years. However, the explanat…
Combining Denoising Autoencoders with Contrastive Learning to fine-tune Transformer Models
Alejo Lopez-Avila, VÃctor Suárez-Paniagua
Recently, using large pretrained Transformer models for transfer learning tasks has evolved to the point where they have become one of the flagship trends in the Natural Language P…
Encoder-Decoder Framework for Interactive Free Verses with Generation with Controllable High-Quality Rhyming
Tommaso Pasini, Alejo López-Ãvila, Husam Quteineh +5
Composing poetry or lyrics involves several creative factors, but a challenging aspect of generation is the adherence to a more or less strict metric and rhyming pattern. To addres…
