Knowledge-based in silico models and dataset for the comparative evaluation of mammography AI for a range of breast characteristics, lesion conspicuities and doses

1 code implementation NeurIPS 2023 Elena Sizikova, Niloufar Saharkhiz, Diksha Sharma, Miguel Lago, Berkman Sahiner, Jana G. Delfino, Aldo Badano

To generate evidence regarding the safety and efficacy of artificial intelligence (AI) enabled medical devices, AI models need to be evaluated on a diverse population of patient cases, some of which may not be readily available.

ViTASD: Robust Vision Transformer Baselines for Autism Spectrum Disorder Facial Diagnosis

1 code implementation30 Oct 2022 Xu Cao, Wenqian Ye, Elena Sizikova, Xue Bai, Megan Coffee, Hongwu Zeng, Jianguo Cao

Research progress in the field of ASD facial analysis in pediatric patients has been hindered due to a lack of well-established baselines.

Improving Computed Tomography (CT) Reconstruction via 3D Shape Induction

1 code implementation23 Aug 2022 Elena Sizikova, Xu Cao, Ashia Lewis, Kenny Moise, Megan Coffee

Chest computed tomography (CT) imaging adds valuable insight in the diagnosis and management of pulmonary infectious diseases, like tuberculosis (TB).

SATBench: Benchmarking the speed-accuracy tradeoff in object recognition by humans and dynamic neural networks

1 code implementation16 Jun 2022 Ajay Subramanian, Sara Price, Omkar Kumbhar, Elena Sizikova, Najib J. Majaj, Denis G. Pelli

Using FLOPs as an analog for reaction time, we compare networks with humans on curve-fit error, category-wise correlation, and curve steepness, and conclude that cascaded dynamic neural networks are a promising model of human reaction time in object recognition tasks.

Semi-supervised Nonnegative Matrix Factorization for Document Classification

no code implementations28 Feb 2022 Jamie Haddock, Lara Kassab, Sixian Li, Alona Kryshchenko, Rachel Grotheer, Elena Sizikova, Chuntian Wang, Thomas Merkh, RWMA Madushani, Miju Ahn, Deanna Needell, Kathryn Leonard

We propose new semi-supervised nonnegative matrix factorization (SSNMF) models for document classification and provide motivation for these models as maximum likelihood estimators.

Large-Scale Unsupervised Object Discovery

1 code implementation NeurIPS 2021 Huy V. Vo, Elena Sizikova, Cordelia Schmid, Patrick Pérez, Jean Ponce

Extensive experiments on COCO and OpenImages show that, in the single-object discovery setting where a single prominent object is sought in each image, the proposed LOD (Large-scale Object Discovery) approach is on par with, or better than the state of the art for medium-scale datasets (up to 120K images), and over 37% better than the only other algorithms capable of scaling up to 1. 7M images.

Anytime Prediction as a Model of Human Reaction Time

no code implementations25 Nov 2020 Omkar Kumbhar, Elena Sizikova, Najib Majaj, Denis G. Pelli

We conclude that Anytime classification (i. e. early exits) is a promising model for human reaction time in recognition tasks.

Learning to Infer Semantic Parameters for 3D Shape Editing

no code implementations9 Nov 2020 Fangyin Wei, Elena Sizikova, Avneesh Sud, Szymon Rusinkiewicz, Thomas Funkhouser

Many applications in 3D shape design and augmentation require the ability to make specific edits to an object's semantic parameters (e. g., the pose of a person's arm or the length of an airplane's wing) while preserving as much existing details as possible.

Semi-supervised NMF Models for Topic Modeling in Learning Tasks

1 code implementation15 Oct 2020 Jamie Haddock, Lara Kassab, Sixian Li, Alona Kryshchenko, Rachel Grotheer, Elena Sizikova, Chuntian Wang, Thomas Merkh, R. W. M. A. Madushani, Miju Ahn, Deanna Needell, Kathryn Leonard

We propose several new models for semi-supervised nonnegative matrix factorization (SSNMF) and provide motivation for SSNMF models as maximum likelihood estimators given specific distributions of uncertainty.

Using Human Psychophysics to Evaluate Generalization in Scene Text Recognition Models

no code implementations30 Jun 2020 Sahar Siddiqui, Elena Sizikova, Gemma Roig, Najib J. Majaj, Denis G. Pelli

Relative to the attention-based (Attn) model, we discover that the connectionist temporal classification (CTC) model is more robust to noise and occlusion, and better at generalizing to different word lengths.
