Large-scale pre-trained models have achieved remarkable success in various computer vision tasks. A standard approach to leverage these is fine-tune all model parameters for downstream tasks, which poses challenges terms of computational and storage costs. Recently, inspired by Natural Language Processing (NLP), parameter-efficient transfer learning has been successfully applied However, most existing techniques primarily focus on single-task adaptation, despite limited research multi-task...

Multi-Task Learning (MTL) is designed to train multiple correlated tasks simultaneously, thereby enhancing the performance of individual tasks. Typically, a multi-task network structure consists shared backbone and task-specific decoders. However, complexity decoders increases with number To tackle this challenge, we integrate decoder-free vision-language model CLIP, which exhibits robust zero-shot generalization capability. Recently, parameter-efficient transfer learning methods have been...

Large-scale pre-trained vision models (PVMs) have shown great potential for adaptability across various downstream tasks. However, with state-of-the-art PVMs growing to billions or even trillions of parameters, the standard full fine-tuning paradigm is becoming unsustainable due high computational and storage demands. In response, researchers are exploring parameter-efficient (PEFT), which seeks exceed performance minimal parameter modifications. This survey provides a comprehensive overview...

We use three years of data from the Supernova Legacy Survey (SNLS) to study general properties core-collapse and type Ia supernovae. This is first such using "rolling search" technique which guarantees well-sampled SNLS light curves good efficiency for supernovae brighter than $i^\prime\sim24$. Using host photometric redshifts, we measure supernova absolute magnitude distribution down luminosities $4.5 {\rm mag}$ fainter normal SNIa. spectroscopy light-curve fitting discriminate against...

Timmes, Brown & Truran found that metallicity variations could theoretically account for a 25% variation in the mass of 56Ni synthesized Type Ia supernovae (SNe Ia), and thus large fraction scatter observed SN luminosities. Higher-metallicity progenitors are more neutron-rich, producing stable burning products relative to radioactive 56Ni. We develop new method estimating bolometric luminosity yield SNe use it test theory with data from Supernova Legacy Survey. find average does drop high...

In real world, training data for person re-identification (Re-ID) is collected discretely with spatial and temporal variations, which requires a model to incrementally learn new knowledge without forgetting old knowledge. This problem called lifelong (LReID). Variations of illumination background images each task exhibit task-specific image style lead task-wise domain gap. addition missing from the tasks, gap key factor catastrophic in LReID, ignored existing approaches LReID.

Greedy-NMS inherently raises a dilemma, where lower NMS threshold will potentially lead to recall rate and higher introduces more false positives. This problem is severe in pedestrian detection because the instance density varies intensively. However, previous works on don't consider or vaguely factor of existent nearby pedestrians.

The evolution of Diffusion Models has dramatically improved image generation quality, making it increasingly difficult to differentiate between real and generated images. This development, while impressive, also raises significant privacy security concerns. In response this, we propose a novel Latent REconstruction error guided feature REfinement method (LaRE^2) for detecting the diffusion-generated We come up with Reconstruction Error (LaRE), first reconstruction-error based in latent space...

Currently in object detection, deep learning based detectors are gaining their momentum. However, the supervision involved widely-used anchor paradigm within detection pipeline is inadequate. Traditional opt for densely picking anchors to increase training samples faster convergence and better quality. dense scheme requires extra computational budget which renders it infeasible lightweight detectors.
