Liquid refractive index sensing independent of opacity using an optofluidic sensor based on diffraction

Zhida Xu, Logan Liu

We have implemented a multi-functional optofluidic sensor that can monitor changes in the refractive index and pressure of biofluid simultaneously and can detect free-solution mole…

MinT: Managed Infrastructure for Training and Serving Millions of LLMs

Mind Lab, :, Song Cao +60

We present MindLab Toolkit (MinT), a managed infrastructure system for Low-Rank Adaptation (LoRA) post-training and online serving. MinT targets a setting where many trained polici…

Macaron-V1: Towards Open Continual Learning with Self-Improvement and Mixture-of-LoRA

Mind Lab, :, Vin Bo +74

Macaron-V1 is an open agent-model family for experiential intelligence: learning from experience in real environments and continuing to learn after deployment. It is organized arou…

On the Scaling of PEFT: Towards Million Personal Models of Trillion Parameters

Mind Lab, :, Vin Bo +64

Parameter-efficient fine-tuning (PEFT) is usually treated as a cheaper alternative to full fine-tuning. We study a broader role: small trainable adapters as persistent local state…

Surface plasmon enhanced broadband spectrophotometry on black silver substrates

Zhida Xu, Logan Liu

We demonstrate surface plasmon-induced enhancements in optical imaging and spectroscopy on silver coated silicon nanocones which we call black silver substrate. The black silver su…
