wenmin-wu/ds-skills

Skill Claude CodeCodex

Removes predicted segmentation masks below a per-class minimum pixel area threshold to eliminate small false positive regions at inference time.

not rated 60 +1 4mo ago A 30 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Uses PyTorch AMP autocast and GradScaler for FP16 training, halving memory usage and speeding up training on modern GPUs.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Combines mixup augmentation (linear interpolation of image pairs and their labels) with label smoothing in a single training pipeline for regularization.

not rated 60 +1 4mo ago A 35 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Route each DICOM series to a per-modality window-center / window-width pair (CT/CTA/MRA/MRI) before normalization, so the same model can ingest mixed modalities without one modality's intensity range washing out the others.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Merges overlapping same-class bounding boxes from multiple annotators into a consensus box using IoU-based matching and intersection.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Combine EfficientNetB0..B6 into one Keras model with a shared image input and one sigmoid head per backbone, training all N models in a single fit() call on TPU.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Generate count-regression training patches at a geometric pyramid of image scales (0.9^k) so one CNN handles within- and between-image object-size variation without explicit anchors.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Stacks uniformly sampled slices from multiple MRI series (e.g., Sagittal T1, T2, Axial) into a single multi-channel tensor for one-pass inference.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Computes per-class ROC-AUC then macro-averages for multi-label classification evaluation and model selection.

wenmin-wu/ds-skills

Skill Claude CodeCodex

For multi-label classification, compute the per-class binary correlation matrix restricted to multi-label rows and the conditional class counts given a rare anchor class — reveals label groupings the model can exploit (shared classifier heads, hierarchical loss weighting, post-hoc consistency rules).

wenmin-wu/ds-skills

Skill Claude CodeCodex

Oversample multi-label images by giving each image a duplication multiplier equal to the max per-class multiplier among its labels, so every rare class gets repetition without exploding common-class counts — the standard fix for long-tail multi-label distributions where SMOTE / per-row oversampling doesn't apply.

wenmin-wu/ds-skills

Skill Claude CodeCodex

Combine match predictions from image embeddings, text similarity, and perceptual hash via set union for maximum recall.

not rated 60 +1 4mo ago A 31 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Auto-detect whether a generated data series is numeric or categorical by measuring the fraction of digit characters in the concatenated values.

not rated 60 +1 4mo ago A 33 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Assign an unknown/novel class when all nearest-neighbor distances exceed a tuned cutoff threshold for open-set recognition.

not rated 60 +1 4mo ago A 29 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Uses Nelder-Mead optimization to find per-class decision thresholds that maximize Quadratic Weighted Kappa for regression-to-ordinal conversion.

not rated 60 +1 4mo ago A 35 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Encodes ordinal classes as cumulative binary labels (class N activates labels 0..N), enabling sigmoid + BCE training for ordinal regression.

not rated 60 +1 4mo ago A 37 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Uses packpaddedsequence to exclude padding tokens from cross-entropy loss in variable-length sequence generation.

not rated 60 +1 4mo ago A 28 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Compute Euclidean distance between entity pairs from tracking data and filter out pairs beyond a threshold to reduce inference candidates.

not rated 60 +1 4mo ago A 30 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Double left-join on tracking data to create pairwise features (positions, velocities, distance) for both entities in an interaction pair.

not rated 60 +1 4mo ago A 36 tokens

wenmin-wu/ds-skills

Skill Claude CodeCodex

Tile a large aerial image into fixed-size patches, accumulate per-class point-annotation counts into a grid tensor aligned with the tiles, and train a small CNN to regress per-class object counts per patch under MSE.
