wenmin-wu/ds-skills

Skill Claude CodeCodex

Selects the top-N most informative tiles from a gigapixel whole slide image by ranking on pixel intensity sum, keeping tiles with the most tissue content.

not rated 60 +1 4mo ago A 39 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Pre-shard TFRecords into N files each balanced along 3 axes (patient, target, image-count), then KFold over file indices for leak-free triple-stratified folds.

Skill Claude CodeCodex

Extract volumetric features from 3D segmentation masks including scan/tumor pixel ratios, tumor percentage, and tumor centroid coordinates.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Tversky loss with independent alpha/beta constants to separately penalize false positives and false negatives in imbalanced segmentation.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Train segmentation with BCE loss first for stable convergence, then fine-tune with Lovasz-hinge on raw logits for IoU-optimal predictions.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Chain a study-level classifier with an image-level detector, merging class probabilities and bounding boxes into a unified prediction.

not rated 60 +1 4mo ago A 31 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Use a lightweight slice-classifier to find the Z-range containing an organ in a CT volume, then crop and trilinear-resample that sub-volume into a fixed shape for a heavier 3D classifier — replaces "use the whole volume" with "use only the relevant slab" at a fraction of the FLOPs.

Skill Claude CodeCodex

Efficiently sample N evenly-spaced frames from a video using OpenCV grab/retrieve pattern with optional resize for batch face detection or classification.

not rated 60 +1 4mo ago A 36 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Extracts calibrated yes/no probabilities from a VQA model by masking all logits except yes/no token variants and renormalizing via softmax.
