coefficients about symbolicmathematics HOT 4 CLOSED

Coefficient tokens will be 'a0', 'a1', ... They are defined in line 43 and 283 of file src/envs/char_sp.py

To use them you need to set parameter n_coefficients to the number you want (1 if you are going to use a0, 2 if you want a0 and a1...), and adjust the second number in leaf_probs (e.g. 0.6,0.2,0.2,0 for 20% of terminal symbols to be coefficients). This should work so long you use less than 10 coefficients (or 8 for differential equations, since we use a8 and a9 as placeholders for integration constants in our generation routine)

You will need to generate new training data using these coefficients, since the model has never seen them at training time (you might try without, but I doubt it works). But it is possible that retraining a pre-trained model on a relatively small additional sample of data featuring the coefficents (aka few shots learning) might work.

Thanks for answering this is really helpful !

The make sense, The last question is how should I declare them ?

Do I need to use the same syntax I used for x, or f that is for instance "a0 = env.local_dict['a0']" or something else ?

Thanks by advance,

Best,

Arthur

I would expect so: for Sympy, a0 is a variable, just like x, and so it should be addressed exactly the same.

Nice, thanks for answering :)
