A quick guide to Amazon’s papers at NeurIPS 2023

Amid topics ranging from experimental design and human-robot interaction to recommender systems and vision-language models, reinforcement learning emerges as a particular focus.

The Conference on Neural Information Processing Systems (NeurIPS) takes place this week, and the Amazon papers accepted there touch on a wide range of topics, from experimental design and human-robot interaction to recommender systems and real-time statistical estimation. Amid that diversity, a few topics come in for particular attention: optimization, privacy, tabular data, time series forecasting, vision-language models — and particularly reinforcement learning.

Code generation

Large language models of code fail at completing code with potential bugs
Tuan Dinh, Jinman Zhao, Samson Tan, Renato Negrinho, Leonard Lausen, Sheng Zha, George Karypis

Complex query answering

Complex query answering on eventuality knowledge graph with implicit logical constraints
Jiaxin Bai, Xin Liu, Weiqi Wang, Chen Luo, Yangqiu Song

Complex query answering.png
An example of a complex eventuality query, with its computational and informational atomics. V is something that happens before a person complains and leaves a restaurant; according to the knowledge graph, V could be either “Service is bad” or “Food is bad”. If V? is the reason for V, then according to the graph, V? could be either “Staff is new”, “PersonY adds ketchup”, “PersonY adds soy sauce”, or “PersonY adds vinegar”. However, from the query, we know that “PersonY adds vinegar” does not happen, and “PersonY adds soy sauce” happens after “food is bad”, so it can’t be the reason for “food is bad”. From “Complex query answering on eventuality knowledge graph with implicit logical constraints”.

Creating a public repository for joining private data
James Cook, Milind Shyani, Nina Mishra

Joining private data.png
A stylized illustration of the repository problem. The sender S uploads a private count sketch capturing which people do and do not have cancer. The receiver R uses the sketch to decorate her data (people's work locations) with a noisy version of S’s cancer column. Two noisy columns are generated: one for cancer (+1) and one for not (−1). R can then build a machine learning model to predict whether employees who work near a toxic waste site are more likely to develop cancer. From “Creating a public repository for joining private data”.

Pei Chen, Soumajyoti Sarkar, Leonard Lausen, Balasubramaniam Srinivasan, Sheng Zha, Ruihong Huang, George Karypis

Table as hypergraph.png
An example of modeling a table as a hypergraph. Cells make up the nodes, and the cells in each row, each column, and the entire table form hyperedges. The table caption and the header names provide the names of the table and column hyperedges. The hypergraph keeps the four structural properties of tables — i.e., row/column permutations result in the same hypergraph. From “HYTREL: Hypergraph-enhanced tabular data representation learning”.
