Extraction of Atypical Aspects from Customer Reviews: Datasets and Experiments with Language Models

1 code implementation5 Nov 2023 Smita Nannaware, Erfan Al-Hossami, Razvan Bunescu

A restaurant dinner may become a memorable experience due to an unexpected aspect enjoyed by the customer, such as an origami-making station in the waiting area.

Can Language Models Employ the Socratic Method? Experiments with Code Debugging

1 code implementation4 Oct 2023 Erfan Al-Hossami, Razvan Bunescu, Justin Smith, Ryan Teehan

When employing the Socratic method of teaching, instructors guide students toward solving a problem on their own rather than providing the solution directly.

Topic-Level Bayesian Surprise and Serendipity for Recommender Systems

1 code implementation11 Aug 2023 Tonmoy Hasan, Razvan Bunescu

One approach to mitigate this undesired behavior is to recommend items with high potential for serendipity, namely surprising items that are likely to be highly rated.

Reclaimer: A Reinforcement Learning Approach to Dynamic Resource Allocation for Cloud Microservices

no code implementations17 Apr 2023 Quintin Fettes, Avinash Karanth, Razvan Bunescu, Brandon Beckwith, Sreenivas Subramoney

Many cloud applications are migrated from the monolithic model to a microservices framework in which hundreds of loosely-coupled microservices run concurrently, with significant benefits in terms of scalability, rapid development, modularity, and isolation.

LSTMs and Deep Residual Networks for Carbohydrate and Bolus Recommendations in Type 1 Diabetes Management

no code implementations6 Mar 2021 Jeremy Beauchamp, Razvan Bunescu, Cindy Marling, Zhongen Li, Chang Liu

In this work, we invert the "what-if" scenario and introduce a similar architecture based on chaining two LSTMs that can be trained to make either insulin or carbohydrate recommendations aimed at reaching a desired BG level in the future.

Changing the Narrative Perspective: From Deictic to Anaphoric Point of View

1 code implementation6 Mar 2021 Mike Chen, Razvan Bunescu

We introduce the task of changing the narrative point of view, where characters are assigned a narrative perspective that is different from the one originally used by the writer.

Mining Functionally Related Genes with Semi-Supervised Learning

no code implementations5 Nov 2020 Kaiyu Shen, Razvan Bunescu, Sarah E. Wyatt

In this paper, we introduce a rich set of features and use them in conjunction with semisupervised learning approaches in order to expand an initial set of seed genes to a larger cluster of functionally related genes.

From Note-Level to Chord-Level Neural Network Models for Voice Separation in Symbolic Music

no code implementations5 Nov 2020 Patrick Gray, Razvan Bunescu

We address this continuum by defining voice separation as the task of decomposing music into streams that exhibit both a high degree of external perceptual separation from the other streams and a high degree of internal perceptual consistency.

Distributed representation of patients and its use for medical cost prediction

no code implementations13 Sep 2019 Xianlong Zeng, Soheil Moosavinasab, En-Ju D Lin, Simon Lin, Razvan Bunescu, Chang Liu

Efficient representation of patients is very important in the healthcare domain and can help with many tasks such as medical risk prediction.

Chord Recognition in Symbolic Music: A Segmental CRF Model, Segment-Level Features, and Comparative Evaluations on Classical and Popular Music

1 code implementation22 Oct 2018 Kristen Masada, Razvan Bunescu

We present a new approach to harmonic analysis that is trained to segment music into a sequence of chord spans tagged with chord labels.

Galaxy morphology prediction using capsule networks

1 code implementation22 Sep 2018 Reza Katebi, Yadi Zhou, Ryan Chornock, Razvan Bunescu

In this work, we studied the performance of Capsule Network, a recently introduced neural network architecture that is rotationally invariant and spatially aware, on the task of galaxy morphology classification.

An Exploration of Data Augmentation and RNN Architectures for Question Ranking in Community Question Answering

no code implementations IJCNLP 2017 Charles Chen, Razvan Bunescu

The automation of tasks in community question answering (cQA) is dominated by machine learning approaches, whose performance is often limited by the number of training examples.
