Ayaan Haque

Hi! I'm Ayaan Haque, a 19 y/o research scientist at Luma AI. I'm also a student at UC Berkeley studying EECS, where I'm advised by Angjoo Kanazawa. I'm currently interested in training generative models. Recently, I worked on Genie, Luma's text to 3D foundation model which can generate high-fidelty 3D objects in seconds.

In the past, I've worked on self-supervised and unsupervised representation learning. I've previously interned at Samsung SDSA, and got my research career jumpstarted back in high school with Wang Group at Stanford. At Berkeley, I'm a part of Machine Learning @ Berkeley and the Nerfstudio team.

In a past life, I was a builder and hacker (I'm a MLH Top-50 Hacker!), and now I'm exploring deep-tech startups. Other than that, I enjoy writing, watching/playing sports, eating out with friends, and just having a good time. My ongoing goal and dream:

Research

Since I've worked on a wide variety of topics (and am still exploring new topics), I've split my publications into currently relevant works and previous works. Only relevant works are listed below. For a full list (and chronological list) of my papers, visit my Google Scholar.

Instruct-NeRF2NeRF: Editing 3D Scenes with Instructions
Ayaan Haque, Matthew Tancik, Alexei A. Efros, Aleksander Holynski, Angjoo Kanazawa
UC Berkeley
ICCV, 2023 (Oral Presentation)
Project Page / ArXiv / Oral / Code

We propose a method for editing NeRF scenes with text-instructions. Given a NeRF of a scene and the collection of images used to reconstruct it, our method uses an image-conditioned diffusion model (InstructPix2Pix) to iteratively edit the input images while optimizing the underlying scene, resulting in an optimized 3D scene that respects the edit instruction.

Self-Supervised Contrastive Representation Learning for 3D Mesh Segmentation
Ayaan Haque, Hankyu Moon, Heng Hao, Sima Didari, Jae Oh Woo, Patrick Bangert
Samsung SDS Research America
AAAI, 2023
ArXiv / Poster

We introduce self-supervised MeshCNN, or SSL-MeshCNN, a novel mesh-specialized contrastive learning method to perform downstream segmentation with limited-labeled data. We create an augmentation policy tailored for meshes, enabling the network to learn efficient visual representations through contrastive pre-training.

Deep Learning for Suicide and Depression Identification with Unsupervised Label Correction
Ayaan Haque*1, Viraaj Reddi*1, Tyler Giallanza2
Saratoga High School1, Princeton University2
ICANN, 2021
Project Page / ArXiv / Teaser Video / Poster / Code / Blog

We propose SDCNL to address the unexplored problem of classifying between depression and more severe suicidal tendencies using web-scraped data. Our method introduces a novel label correction method to remove inherent noise in web-scraped data using unsupervised learning combined with a deep-learning classifier based on pre-trained transformers.

MultiMix: Sparingly Supervised, Extreme Multitask Learning From Medical Images
Ayaan Haque*1, Abdullah-Al-Zubaer Imran*2,3, Adam Wang2, Demetri Terzopoulos3,4
Saratoga High School1, Stanford University2, University of California, Los Angeles3, VoxelCloud Inc.4
IEEE ISBI, 2021
Project Page / ArXiv / Poster / Presentation / Code / Blog

We introduce MultiMix, a joint semi-supervised classification and segmentation model employing a confidence-based augmentation strategy for semi-supervised classification along with a novel saliency bridge module that guides segmentation and provides explainability for the joint tasks.

EC-GAN: Low-Sample Classification using Semi-Supervised Algorithms and GANs
Ayaan Haque
Saratoga High School
AAAI, 2021 (Best Student Abstract Finalist, Oral Presentation)
Project Page / ArXiv / Oral / Poster / Presentation / Code / Blog

We propose EC-GAN, which combines a Generative Adversarial Network with a classifier to leverage artifical GAN generations to increase the size of restricted, fully-supervised datasets using semi-supervised algorithms. Mentored by Microsoft Postdoc and Princeton University PhD Jordan T. Ash.

Previous Research
Noise2Quality: Non-Reference, Pixel-Wise Assessment of Low Dose CT Image Quality
Ayaan Haque1, 2, Adam Wang2, Abdullah-Al-Zubaer Imran2
Saratoga High School1, Stanford University2
SPIE Medical Imaging (SPIE), 2022
Project Page / Paper / Presentation / Poster / Code

We propose Noise2Quality (N2Q), a novel, self-supervised IQA model which predicts SSIM Image Quality maps from low-dose CT. We propose a self-supervised regularization task of dose-level estimation creating a multi-tasking framework to improve performance.

Window Level is a Strong Denoising Surrogate
Ayaan Haque1, 2, Adam Wang2, Abdullah-Al-Zubaer Imran2
Saratoga High School1, Stanford University2
MICCAI MLMI, 2021
Project Page / ArXiv / Poster / Code / Blog

We introduce SSWL-IDN, a novel self-supervised CT denoising window-level prediction surrogate task. Our method is task-relevant and related to the downstream task, yielding improved performance over recent methods.

Generalized Multi-Task Learning from Substantially Unlabeled Multi-Source Medical Image Data
Ayaan Haque1, 2, Abdullah-Al-Zubaer Imran2,3, Adam Wang2, Demetri Terzopoulos3,4
Saratoga High School1, Stanford University2, University of California, Los Angeles3, VoxelCloud Inc.4
MELBA, 2021
Project Page / Journal Page / Paper / Code

We expand upon MultiMix (in ISBI 2021). Our extended manuscript contains a detailed explanation of the methods, saliency map visualizations from multiple datasets, and quantitative (performance metrics tables) and qualitative (mask predictions, Bland Altman plots, ROC curves, consistency plots).

Drishti Smartphone Retinal Camera System
CAD Files and Implementation Drishti's Retinal Camera System Prototype
June 2021 - Sep 2021
Github (CAD Files) / Assembly Guide / Instructional Guide / Documentation / Technical Blog / Drishti Website

This mobile, on-the-go system is designed for clinics in Bangladesh to screen patients for Diabetic Retinopathy (DR) using a smartphone camera with a retinal attachment. The purpose of this rig is to allow precise positioning of the smartphone to any patient's left and right eye such that the images can be efficiently fed into Drishti's AI algorithms for DR diagnosis. The system is completely adjustable for all head sizes. It is made of readily available components that can be purchased at many local hardware stores, and is designed for low-cost fabrication. All assembly tools are common household tools or easily purchasable/rentable from a local hardware store. The 3D-printed components can be printed on low-end machines and with cheap PLA filament. We designed this system to be completely collapsable, such that it can fit into a standard size backpack.
