Simple Contrastive Splice Site Prediction

Kevin Brar

Reader's Note

  • Paper's name in repo is SimCSP.pdf

EXPERIMENTS:

  • 1: relationship between f1/sccs in pretrain and fine-tune and its affects on F1 score
    • uses the last layer's [CLS] token
    • uses SpliceBERT-human, evaluated using f1/sccs on spliceator and NMI on hg19
    • could be improved by using SpliceBERT and NMI on spliceator
  • 2 - hyperparameter search over pre-train w/ SCCS validation
  • 3: experiment with chopping off 1 layers transformer and doing CL + fine-tune on that
  • 4: experiment with chopping off 2 transformer layers and doing CL + fine-tune on that
  • 5: freeze the transformer layers and only fine-tune the classifier
    • this will tell you if the internal representation is being improved

METRICS:

  • SCCS : spearman correlation w/ cosine similarity
  • NMI : normalized mutual information
  • F1 : linear combination of precision and recall

EXPERIMENTAL PIPELINE:

  • pretrain.sh
  • finetune.sh
