Inductive Bias
Assumptions about data structure built into a machine learning model at design time, guiding the model to preferentially search for specific types of solutions in function space. Directly related to generalization error bounds, correct symmetry constraints serve as essentially free regularization.

This theoretical study warns against the current trend in MLIP model design of pursuing larger, more flexible, and less physically constrained models: relaxing inductive bias can improve fitting accuracy and computational efficiency but may sacrifice sampling reliability.
To ensure the sampling reliability of MLIPs, one cannot rely solely on pointwise matching of energies and forces, but needs to introduce appropriate inductive bias or constraints to guarantee the correctness of the global distribution.
The physics-driven positional encoding introduced by STCNet provides an inductive bias that ensures the reconstruction result does not contradict the geometric relationship of the X-ray projections, and the temporal encoding constrains the motion between phases to conform to respiratory dynamics.
'Shifting model capacity from scene appearance to object dynamics' is a reallocation of the supervision signal and can be understood as an injection of inductive bias, but it cannot create information that does not exist in the data out of thin air.
Inductive bias refers to assumptions about the structure of the target problem that are pre-embedded during the model design stage, which can narrow the hypothesis space and improve sample efficiency.
Human learning of new skills relies on prior knowledge transfer, causal reasoning, and highly compressed conceptual representations, a capability referred to in cognitive science as inductive bias.
