Data representation
Encode sequences, structures, expression profiles, images and populations in forms appropriate to the biological question.
Subject
Purpose
Biological questions studied through algorithms, statistical models, simulation and large-scale molecular, cellular and population data.
Structure
Components → constraints → flows → control → failure
Computational biology becomes rigorous when model choice, data-generating process and biological interpretation remain connected rather than treating analysis as a detached pipeline.
Encode sequences, structures, expression profiles, images and populations in forms appropriate to the biological question.
Choose statistical, optimization or machine-learning methods whose assumptions match the structure and scale of the data.
Separate training performance from generalization and quantify uncertainty when data are sparse, biased or batch-structured.
Use computational experiments to explore mechanisms, parameter regimes and hypotheses that are difficult to isolate experimentally.
Translate computational output back into mechanisms, testable predictions and limits that domain experts can challenge.
prediction accuracy ≠ biological explanation
large dataset ≠ representative dataset
association ≠ mechanism
How does the data-generating process constrain what an algorithm can learn?
Which validation split matches the biological generalization being claimed?
What new experiment would distinguish a useful computational hypothesis from an attractive pattern?
Benchmarking, external validation and biological replication matter more than model complexity; batch effects, leakage and sampling bias must be actively tested.
