Using Deep Autoregressive Models as Causal Inference Engines

no code implementations27 Sep 2024 Daniel Jiwoong Im, Kevin Zhang, Nakul Verma, Kyunghyun Cho

We propose an autoregressive (AR) CI framework capable of handling complex confounders and sequential actions common in modern applications.

Contrastive Loss is All You Need to Recover Analogies as Parallel Lines

1 code implementation14 Jun 2023 Narutatsu Ri, Fei-Tzin Lee, Nakul Verma

While static word embedding models are known to represent linguistic analogies as parallel lines in high-dimensional space, the underlying mechanism as to why they result in such geometric structures remains obscure.

Improving Model Training via Self-learned Label Representations

1 code implementation9 Sep 2022 Xiao Yu, Nakul Verma

In this work, we demonstrate that more sophisticated label representations are better for classification than the usual one-hot encoding.

An analysis of document graph construction methods for AMR summarization

no code implementations27 Nov 2021 Fei-Tzin Lee, Chris Kedzie, Nakul Verma, Kathleen McKeown

Prior work in AMR-based summarization has automatically merged the individual sentence graphs into a document graph, but the method of merging and its effects on summary content selection have not been independently evaluated.

Solving Probability and Statistics Problems by Program Synthesis

no code implementations16 Nov 2021 Leonard Tang, Elizabeth Ke, Nikhil Singh, Nakul Verma, Iddo Drori

Our work is the first to introduce a new dataset of university-level probability and statistics problems and solve these problems in a scalable fashion using the program synthesis capabilities of large language models.

Solving Linear Algebra by Program Synthesis

no code implementations16 Nov 2021 Iddo Drori, Nakul Verma

We solve MIT's Linear Algebra 18. 06 course and Columbia University's Computational Linear Algebra COMS3251 courses with perfect accuracy by interactive program synthesis.

Automated Symbolic Law Discovery: A Computer Vision Approach

no code implementations AAAI 2021 Hengrui Xing, Ansaf Salleb-Aouissi, Nakul Verma

This is not a trivial problem as it involves searching for a complex mathematical relationship over a large set of explanatory variables and operators that can be combined in an infinite number of ways.

Meta-Learning to Cluster

no code implementations30 Oct 2019 Yibo Jiang, Nakul Verma

By providing multiple types of training datasets as inputs, our model has the ability to generalize well on unseen datasets (new clustering tasks).

Model-Agnostic Meta-Learning using Runge-Kutta Methods

no code implementations16 Oct 2019 Daniel Jiwoong Im, Yibo Jiang, Nakul Verma

By leveraging this refined control, we demonstrate that there are multiple principled ways to update MAML and show that the classic MAML optimization is simply a special case of second-order Runge-Kutta method that mainly focuses on fast-adaptation.

Metric Learning on Manifolds

no code implementations5 Feb 2019 Max Aalto, Nakul Verma

Recent literature has shown that symbolic data, such as text and graphs, is often better represented by points on a curved manifold, rather than in Euclidean space.

Noise-tolerant fair classification

1 code implementation NeurIPS 2019 Alexandre Louis Lamy, Ziyuan Zhong, Aditya Krishna Menon, Nakul Verma

We finally show that our procedure is empirically effective on two case-studies involving sensitive feature censoring.

Stochastic Neighbor Embedding under f-divergences

no code implementations3 Nov 2018 Daniel Jiwoong Im, Nakul Verma, Kristin Branson

A common concern with $t$-SNE criterion is that it is optimized using gradient descent, and can become stuck in poor local minima.

Sample complexity of learning Mahalanobis distance metrics

no code implementations NeurIPS 2015 Nakul Verma, Kristin Branson

Metric learning seeks a transformation of the feature space that enhances prediction quality for the given task at hand.

Learning the structure of manifolds using random projections

no code implementations NeurIPS 2007 Yoav Freund, Sanjoy Dasgupta, Mayank Kabra, Nakul Verma

We present a simple variant of the k-d tree which automatically adapts to intrinsic low dimensional structure in data.
