Each `Instance` in a `Scenario` looks like this: | ||
<input> -> <reference1> | ||
<reference2> | ||
<reference3> [correct] | ||
<reference4> | ||
<instance_chain_of_thought> | ||
We can define a label (e.g., letter) for each reference: | ||
<global_prefix> | ||
<instructions> | ||
<input_prefix> | ||
<input> # train | ||
<input_suffix> | ||
A. <reference1> | ||
B. <reference2> | ||
C. <reference3> | ||
D. <reference4> | ||
<output_prefix> | ||
<chain_of_thought_prefix> | ||
<instance_chain_of_thought> | ||
<chain_of_thought_suffix> | ||
<output> | ||
<output_suffix> | ||
<input_prefix> | ||
<input> # test | ||
<input_suffix> | ||
A. <reference1> | ||
B. <reference2> | ||
C. <reference3> | ||
D. <reference4> | ||
<output_prefix> | ||
<chain_of_thought_prefix> | ||
<instance_chain_of_thought> | ||
<chain_of_thought_suffix> | ||
<output> | ||
<output_suffix> | ||
<global_suffix> | ||
In general, each example is: | ||
<input_prefix><input><input_suffix><reference_prefixes[index]><reference> \ | ||
<output_prefix><chain_of_thought_prefix><chain_of_thought><chain_of_thought_suffix><output><output_suffix> | ||
