Alteration-free and Model-agnostic Origin Attribution of Generated Images
Recently, there has been a growing attention in image generation models.
However, concerns have emerged regarding potential misuse and intellectual
property (IP) infringement associated with these models. Therefore, it is
necessary to analyze the origin of images by inferring if a specific image was
generated by a particular model, i.e., origin attribution. Existing methods are
limited in their applicability to specific types of generative models and
require additional steps during training or generation. This restricts their
use with pre-trained models that lack these specific operations and may
compromise the quality of image generation. To overcome this problem, we first
develop an alteration-free and model-agnostic origin attribution method via
input reverse-engineering on image generation models, i.e., inverting the input
of a particular model for a specific image. Given a particular model, we first
analyze the differences in the hardness of reverse-engineering tasks for the
generated images of the given model and other images. Based on our analysis, we
propose a method that utilizes the reconstruction loss of reverse-engineering
to infer the origin. Our proposed method effectively distinguishes between
generated images from a specific generative model and other images, including
those generated by different models and real images
How to Detect Unauthorized Data Usages in Text-to-image Diffusion Models
Recent text-to-image diffusion models have shown surprising performance in
generating high-quality images. However, concerns have arisen regarding the
unauthorized usage of data during the training process. One example is when a
model trainer collects a set of images created by a particular artist and
attempts to train a model capable of generating similar images without
obtaining permission from the artist. To address this issue, it becomes crucial
to detect unauthorized data usage. In this paper, we propose a method for
detecting such unauthorized data usage by planting injected memorization into
the text-to-image diffusion models trained on the protected dataset.
Specifically, we modify the protected image dataset by adding unique contents
on the images such as stealthy image wrapping functions that are imperceptible
to human vision but can be captured and memorized by diffusion models. By
analyzing whether the model has memorization for the injected content (i.e.,
whether the generated images are processed by the chosen post-processing
function), we can detect models that had illegally utilized the unauthorized
data. Our experiments conducted on Stable Diffusion and LoRA model demonstrate
the effectiveness of the proposed method in detecting unauthorized data usages
Pregnancy Outcomes in Double Stimulation versus Two Consecutive Mild Stimulations for IVF in Poor Ovarian Responders
To compare pregnancy outcomes between double stimulation (DouStim) and two consecutive mild stimulations in poor ovarian responders, this study retrospectively analyzed 281 patients diagnosed as having poor ovarian response (POR) who underwent oocytes retrieval for in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) from January 2018 to December 2020. They were divided into two groups: the DouStim group (n = 89) and the two consecutive mild stimulations group (n = 192). The results illustrated that there were no significant differences in the number of oocytes and 2PNs between the two groups. The number of frozen embryos [1 (0, 2) versus 1(0, 2)] was significantly lower and the proportion of patients without frozen embryos (39.3% versus 26.0%) was significantly higher in the DouStim group than in the two consecutive mild stimulations group (p p > 0.05). The intra-subgroup comparison showed that in young POR patients under 35 years old, there were no significant differences in clinical indicators and pregnancy outcomes (p > 0.05). In elderly POR patients aged 35 years and above, the number of frozen embryos [1 (0, 1.5) versus 1 (0.25, 2)] (p p > 0.05). In conclusion, the DouStim protocol is inferior to the two consecutive mild stimulations protocol in terms of the number of frozen embryos, which mainly occurs in elderly patients, but there is no difference in pregnancy outcomes between the two protocols
CEPC Technical Design Report -- Accelerator
International audienceThe Circular Electron Positron Collider (CEPC) is a large scientific project initiated and hosted by China, fostered through extensive collaboration with international partners. The complex comprises four accelerators: a 30 GeV Linac, a 1.1 GeV Damping Ring, a Booster capable of achieving energies up to 180 GeV, and a Collider operating at varying energy modes (Z, W, H, and ttbar). The Linac and Damping Ring are situated on the surface, while the Booster and Collider are housed in a 100 km circumference underground tunnel, strategically accommodating future expansion with provisions for a Super Proton Proton Collider (SPPC). The CEPC primarily serves as a Higgs factory. In its baseline design with synchrotron radiation (SR) power of 30 MW per beam, it can achieve a luminosity of 5e34 /cm^2/s^1, resulting in an integrated luminosity of 13 /ab for two interaction points over a decade, producing 2.6 million Higgs bosons. Increasing the SR power to 50 MW per beam expands the CEPC's capability to generate 4.3 million Higgs bosons, facilitating precise measurements of Higgs coupling at sub-percent levels, exceeding the precision expected from the HL-LHC by an order of magnitude. This Technical Design Report (TDR) follows the Preliminary Conceptual Design Report (Pre-CDR, 2015) and the Conceptual Design Report (CDR, 2018), comprehensively detailing the machine's layout and performance, physical design and analysis, technical systems design, R&D and prototyping efforts, and associated civil engineering aspects. Additionally, it includes a cost estimate and a preliminary construction timeline, establishing a framework for forthcoming engineering design phase and site selection procedures. Construction is anticipated to begin around 2027-2028, pending government approval, with an estimated duration of 8 years. The commencement of experiments could potentially initiate in the mid-2030s
