A locally-built, LLM-digested index of recent arXiv papers in quant finance, geometry/topology, and statistical ML — keyword search served straight from SQLite on this machine.
Proposes a method for ranking items across multiple aspects based on user feedback.
MSTREAM detects anomalies in multi-aspect data streams.
Proposes a method to cluster multi-aspect data using manifold learning with NMF.
Many problems in machine learning and related application areas are fundamentally variants of conditional modeling and sampling across multi-aspect data, either multi-view, multi-modal, or simply multi-group. For example, sampling from the distribution of English sentences conditioned on a given French sentence or samp…
asp2vec learns dynamic node aspect distributions for better network embedding.
Linking authors of short-text contents has important usages in many applications, including Named Entity Recognition (NER) and human community detection. However, certain challenges lie ahead. Firstly, the input short-text contents are noisy, ambiguous, and do not follow the grammatical rules. Secondly, traditional tex…
HiJoD detects misinformation using multiple aspects and outperforms state-of-the-art methods.
The PARAFAC tensor decomposition has enjoyed an increasing success in exploratory multi-aspect data mining scenarios. A major challenge remains the estimation of the number of latent factors (i.e., the rank) of the decomposition, which yields high-quality, interpretable results. Previously, we have proposed an automate…
A popular tool for unsupervised modelling and mining multi-aspect data is tensor decomposition. In an exploratory setting, where and no labels or ground truth are available how can we automatically decide how many components to extract? How can we assess the quality of our results, so that a domain expert can factor th…
Selection of input features such as relevant pieces of text has become a common technique of highlighting how complex neural predictors operate. The selection can be optimized post-hoc for trained models or incorporated directly into the method itself (self-explaining). However, an overall selection does not properly c…
This paper improves fairness in recommendation systems by learning individual preferences across multiple dimensions.
CLIP dataset helps extract action items from hospital discharge notes.
COCKATIEL explains neural net models on NLP tasks by identifying meaningful concepts.
FunBaT extends Tucker decomposition to handle continuous-indexed tensor data.
