On the colour bimodality of globular cluster systems # 세줄 요약 # We study optical/near-infrared (NIR) colour distributions of the GC systems in 14 E/S0 galaxies. We find that double-peaked colour distributions are more commonly seen in optical than in optical/NIR colours A bimodal optical colour distribution is not necessarily an indication of an underlying bimodal metallicity distribution. # 상세 리뷰 # 1.

Campanella et al., 2019, Clinical-grade computational pathology using weakly supervised deep learning on whole slide images. # 세줄 요약 # The development of decision support systems for pathology and their deployment in clinical practice have been hindered by the need for large manually annotated datasets. We present a multiple instance learning-based deep learning system that uses only reported diagnoses as labels for training. Tests on prostate cancer, basal cell carcinoma and breast cancer metastases to axillary lymph.. 2021. 10. 4. Zhang et al., 2019, An investigation of CNN models for differentiating malignant from benign lesions using small pathologically proven datasets # 세줄 요약 # Cancer has been one of the most threatening diseases, so our major goal is to identify malignant from benign lesions at radiology or CT imaging in the early stages, But it is difficult to collect such a large volume of images with pathological information. This paper explores two CNN models by focusing extensively on the expansion of training samples from two small pathologically prove.. 2021. 9. 27. Medina et al., 2020. Deep learning method for segmentation of rotator cuff muscles on MR images # 세줄 요약 # To develop and validate a deep convolutional neural network (CNN) method capable of (1) selecting a specific shoulder sagittal MR image (Y-view) and (2) automatically segmenting rotator cuff (RC) muscles on a Y-view. For model A, we manually selected shoulder sagittal T1 Y-view from 258 cases as ground truth to train a classification, For model B, we manually segmented subscapularis, s.. 2021. 9. 19. Cohen & Blakeslee & Ryzhov, 1998, The Ages and Abundances of a Large Sample of M87 Globular Clusters # 세줄 요약 # Combining the new (20 GCs; this paper) and existing data (150 GCs; Cohen & Ryzhov, 1997) for the galactic GCs (Globular clusters) and comparing the (U-R) colors and the line indices gave qualitative indications for the ages and abundances of M87 GC system. We find that the M87 GCs span a wide range in metallicity, from very metal-poor to somewhat above solar metallicity. The behavior o.. 2021. 8. 28. Depthwise Separable convolution이 기존의 convolution 보다 연산량이 적은 이유 # 세줄 요약 # Depthwise separable convolution 은 각 채널별로 나누어 각각의 feature map에 대해 1-channel convolution을 연산하는 depthwise 단계와 채널별로 구해진 feature map을 1x1 kernal convolution으로 하나의 channel로 합성시키는 separable 단계로 이루어져 있다. 일반적인 convolution의 연산량은 다음의 식으로 계산한다: (kernel size)^2 * (input channel number) * (input_size)^2 * (output channel number) * (output size)^2 Depthwise separable convolution의 경우 depthwise 단계에서 in.. 2021. 8. 25. Pota et al., 2015, A SLUGGS and Gemini/GMOS combined study of the elliptical galaxyM60: wide-field photometry and kinematics of the globular cluster system # 세줄 요약 # We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster. We confirm significant GC colour bimodality and find that the red GCs are more centrally concentrated, while the blue GCs are more spatially extended. We find that formation via a major merger between two gas-poor galaxies, followe.. 2021. 8. 23. 리눅스 터미널에서 텐서플로가 GPU를 잡고 있는지 확인하는 방법 # 세줄요약 # NVIDIA GPU driver와 CUDA가 설치되어있는지 확인 한다.

Shim et al., 2020, Automated rotator cuff tear classification using 3D convolutional neural network # 세줄 요약 # Rotator cuff tear (RCT) is one of the most common shoulder injuries. When diagnosing RCT, skilled orthopedists visually interpret magnetic resonance imaging (MRI) scan data. MRI data from 2,124 patients were used to train and test the VRN-based 3D CNN to classify RCT into five classes (None, Partial, Small, Medium, Large-to-Massive). The VRN-based 3D CNN outperformed orthopedists speci.. 2021. 8. 8. 이전 1 ··· 5 6 7 8 9 10 11 ··· 15 다음
