AMIGO: Agentic Multi-Image Grounding Oracle Benchmark
Min Wang, Ata Mahjoubfar
Agentic vision-language models increasingly act through extended interactions, but most evaluations still focus on single-image, single-turn correctness. We introduce \textbf{AMIGO…
FashionVQA: A Domain-Specific Visual Question Answering System
Min Wang, Ata Mahjoubfar, Anupama Joshi
Humans apprehend the world through various sensory modalities, yet language is their predominant communication channel. Machine learning systems need to draw on the same multimodal…
Designing an Efficient End-to-end Machine Learning Pipeline for Real-time Empty-shelf Detection
Dipendra Jha, Ata Mahjoubfar, Anupama Joshi
On-Shelf Availability (OSA) of products in retail stores is a critical business criterion in the fast moving consumer goods and retails sector. When a product is out-of-stock (OOS)…
Neuromorphic Computing for Content-based Image Retrieval
Te-Yuan Liu, Ata Mahjoubfar, Daniel Prusinski +1
Neuromorphic computing mimics the neural activity of the brain through emulating spiking neural networks. In numerous machine learning tasks, neuromorphic chips are expected to pro…
Deep Cytometry: Deep learning with Real-time Inference in Cell Sorting and Flow Cytometry
Yueqin Li, Ata Mahjoubfar, Claire Lifan Chen +3
Deep learning has achieved spectacular performance in image and speech recognition and synthesis. It outperforms other machine learning algorithms in problems where large amounts o…
Time Stretch Inspired Computational Imaging
Bahram Jalali, Madhuri Suthar, Mohamad Asghari +1
We show that dispersive propagation of light followed by phase detection has properties that can be exploited for extracting features from the waveforms. This discovery is spearhea…
The Temporal Gearbox
Bahram Jalali, Jacky C. K. Chan, Ata Mahjoubfar +2
We are inspired by mechanical gearboxes and demonstrate its analog counterpart in optics. We use nonlinear dispersion modes as "gears" to overcome the mismatch between the ultrahig…
Optical Hardware Accelerators using Nonlinear Dispersion Modes for Energy Efficient Computing
Bahram Jalali, Ata Mahjoubfar
This paper proposes a new class of hardware accelerators to alleviate bottlenecks in the acquisition, analytics, storage and computation of information carried by wideband streamin…
Differentially-Enhanced Sideband Imaging via Radio-frequency Encoding
A. M. Fard, A. Mahjoubfar, B. Jalali
We present a microscope paradigm that performs differential interference imaging with high sensitivity via optical amplification and radio-frequency (RF) heterodyne detection. This…
High-throughput Biological Cell Classification Featuring Real-time Optical Data Compression
Bahram Jalali, Ata Mahjoubfar, Claire L. Chen
High throughput real-time instruments are needed to acquire large data sets for detection and classification of rare events. Enabled by the photonic time stretch digitizer, a new c…
Reconstruction in Time-Bandwidth Compression Systems
Jacky Chan, Ata Mahjoubfar, Mohammad H. Asghari +1
Recently it has been shown that the intensity time-bandwidth product of optical signals can be engineered to match that of the data acquisition instrument. In particular, it is pos…
