Next K-mer Prediction

Abouts

The Next K-mer Prediction task is a zero-shot evaluation method introduced in the GENERator paper to assess the quality of pretrained models. It involves inputting a sequence segment into the model and having it predict the next K base pairs. The predicted sequence is then compared to the actual sequence to assess accuracy.

• Sequence: The input sequence has a maximum length of 96k base pairs (bp). You can control the number of input tokens by applying left truncation.
• Label: The next 128 bp immediately following the end of the input sequence.

Note: Prediction time may increase significantly for longer input sequences. It is strongly recommended to begin testing with a smaller number of input tokens to optimize performance.

How to use

from datasets import load_dataset

datasets = load_dataset("GenerTeam/next-kmer-prediction", "eukaryote") # or "bacteria" or "others"
