Optimal Subsampling with Influence Functions
As the amount of data increases, the question arises as to how best to deal with the large datasets. While computational platforms such as Spark [28] and Ray [23] help process large datasets once a desired model is chosen, simply using smaller data can be a faster solution for exploratory data modeling, rapid prototyping, or other tasks where the accuracy obtainable from the full dataset is notneeded.

Out of the box, these models take as input a sequence of vectors in embedding space and output asequence ofvectors inthe same space. We treat the prediction of the model at the position corresponding toxi (that is absolute position 2i 1)asthepredictionof f(xi). A.2 Training Each training prompt is produced by sampling a random functionf from the function class we are training on, then sampling inputsxi from the isotropic Gaussian distributionN(0,Id) and constructing apromptas(x1,f(x1),...,xk,f(xk)). For the class of decision trees, the random functionf is represented by a decision tree of depth4 (with16leafnodes),with20dimensionalinputs. Minimum norm least squares is the optimal estimator for the linear regression problem.

However,inpractice, we did not find both effects inthe training. The last term in the loss function of COMET does not need the information from the dataset. This section contains the experiment details for cases tested in section 4. In section 4, there are 6 simple experiments performed todemonstrate the capability ofCOMET:(1) mass-spring, (2) 2D Case5: 2Dnonlinear spring.Weconsider acaseofamotion ofanobjectofmassm=1in2D where it is connected to the origin with a nonlinear spring with forceF = |r|2r where r is the position of the object in 2D coordinate. The constants of motion of this systems are the energy and the angular momentum,whichmakesnc=2. Case 6: Lotka-Volterraequation isanordinary differential equation modelling thepopulation of predatorandprey. The training loss in this case was composed of the reconstruction loss and the dynamics loss.
