eccDNA Copy-Number Level Prediction (Threshold = 4.5)

This dataset supports the eccDNA copy-number prediction task,
where the model learns to infer relative copy-number levels directly from eccDNA sequences.

Each entry contains:

• sequence: DNA string (A/T/C/G)
• label: copy-number stratum (e.g., 0 = low, 1 = high)

Task Description

Predicting eccDNA copy-number levels is biologically meaningful,
as eccDNA abundance reflects amplification intensity and oncogenic potential.

This dataset is derived from eccDNAdb and contains balanced examples
across multiple copy-number thresholds (e.g., >10 and >4.5).
