Could AI-powered image recognition be a game changer for Japans scallop farming industry? Responsible Seafood Advocate
In two-stage object detection, one branch of object detectors is based on multi-stage models. Deriving from the work of R-CNN, one model is used to extract regions of objects, and a second model is used to classify and further refine the localization of the object. The R-CNN (Girshick et al., 2014) series, R-FCN (Dai et al., 2016), Mask R-CNN (He et al., 2017), and other algorithms are examples. The innovative development of online course-supportive big data platforms and related data processing technologies has become a new research focus.
Thus, these parameters offer a means for mitigating bias from an AI standpoint. As such, our goal was not to elucidate all of the features enabling AI-based race prediction, but instead focus on those that could lead to straightforward AI strategies for reducing AI diagnostic performance bias. To this end, our analysis is not intended to advocate for the removal of the ability to predict race from medical images, rather to better understand potential technical dataset factors that influence this behavior and improve AI diagnostic fairness. Firstly, the actions in sports images are complex and diverse, making it difficult to capture complete information from a single frame.
It has gained popularity in natural language processing tasks, such as machine translation and language modeling. Google’s BERT model is an example of the Transformer architecture, achieving outstanding results in many NLP tasks30. The Transformer model has many advantages, such as parallel computing and capturing long-distance dependencies, but it can also be complex and sensitive to sequence length variations. Researchers have begun exploring the application of Transformer-based methods in 2D image segmentation tasks. In aerial images, Bi et al. employed ViT for object classification33, and some studies have applied it to forest fire segmentation34. In tunnel construction, Transformer has been used for similar tasks, such as crack detection35,36,37,38, electronic detonator misfire detection39, automatic low-resolution borehole image stitching, and improving GPR surveys in tunnel construction40,41.
Next, images are tessellated into small patches and normalized to remove color variations. The normalized patches are fed to a deep-learning model to derive patch-level representations. Finally, a model based on multiple instance learning (VarMIL) was utilized to predict the patient subtype. The effects of view position were quantified in a similar fashion by comparing the average racial identity prediction scores for each view position compared to the average scores across all views. Figure 3 additionally compares these values to differences in the empirical frequencies of the view positions across patient race.
Our study’s objective is to create an AI tool for effortless detection of authentic handloom items amidst a sea of fakes.

During this stage, the classification models start categorizing new, real-time data, enabling successful data classification at scale. This step forms the basis for training the AI model and involves collecting a comprehensive and representative dataset that reflects the real-world scenarios the model will encounter. The quality and quantity of the data directly impact the model’s ability to learn and make accurate predictions. AI data classification can be used for a wide range of applications using a number of different tools. Implementing this process requires a thorough understanding of the steps involved and the classification types, as well as familiarity with various AI-training methods.
The models listed in the table are arranged in descending order of their Dice coefficient performance. The best-performing model is Transformer + UNet, with a Dice score of 95.43%, mIoU of 91.29%, MPa of 95.57%, mRecall of 95.57%, and mPrecision of 95.31%. This model combines the architectures of Transformer and UNet, enabling it to effectively capture spatial and contextual information. The ai based image recognition “PAN” model is the second-best performer with a score of 86.01%, and “DeeplabV3” is the third-best performer with a score of 82.78%. Traditional methods primarily rely on on-site sampling and laboratory testing, such as uniaxial compressive strength (UCS) tests and velocity tests. While these methods provide relatively accurate rock strength data, they are complex and time-consuming1,2,3.
To test the impact of solely FFT-Enhancer on the output, we trained both the baseline and adversarial networks with and without this module. It’s important to note that while the FFT-Enhancer can enhance images, it’s not always perfect, and there may be instances of noise artifacts in the output image. To assess its impact on the model, we experimented with different probabilities of applying the FFT-Enhancer during training for both AIDA and Base-FFT. Optimal results were achieved with probabilities ranging from 40% to 60% across all datasets. Decreasing the probability below 40% led to a drop in the models’ balanced accuracy, as insufficient staining information from the target domain was utilized during training. Conversely, applying the FFT-Enhancer more than 60% resulted in noise artifacts that hindered the network’s performance.

Indeed, we do find that AI models trained to predict pathological findings exhibit different score distributions for different views (Supplementary Fig. You can foun additiona information about ai customer service and artificial intelligence and NLP. 4). This observation can help explain why choosing score thresholds per view can help mitigate the underdiagnosis bias. We note, however, that this strategy did not completely eliminate the performance bias, leaving room for improvement in future work. Furthermore, it is important to consider both sensitivity and specificity when calibrating score distributions and assessing overall performance and fairness42,46,47,48. Calibration and the generalization of fairness metrics across datasets is indeed an unsolved, general challenge in AI regardless of how thresholds are chosen49 (see also Supplementary Fig. 5). Our results above suggest that technical factors related to image acquisition and processing can influence the subgroup behavior of AI models trained on popular chest X-ray datasets.
While we focused on studying differences in technical factors from an AI perspective, understanding how these differences arise to begin with is a critical area of research. The differences in view position utilization rates observed here are qualitatively similar to recent findings of different utilization rates of thoracic imaging by patient race21,22,23,53. As different views and machine types (e.g., fixed or portable) may be used for different procedures and patient conditions, it is important to understand if the observed differences underlie larger disparities.

On the contrary, eccentricity is an image metric that can qualitatively evaluate the shape of each organoid, regardless of its size (Supplementary Table S3). Passaged colon organoids without dissociation were differentially filtered using cell strainers sized 40 μm, 70 μm, and 100 μm. One day after the organoids were seeded in a 24-well plate, 19 images were acquired (Supplementary Table S2). Representative images of organoids in three size ranges, along with the output images, are shown (Fig. 4a). Original images were first processed using OrgaExtractor, followed by the selection of actual organoids. Organoids that were neither cut at the edges nor smaller than 40 μm in size were selected as actual organoids.
