1 | What are "Coarse Procedures"? |
2 | ----------------------------- |
3 | |
4 | A "coarse procedure" is some rough, often handwritten code that solves a subset of a difficult or open-ended task. |
5 | |
6 | Example: |
7 | |
8 | static String containsGazelle(String s) {
|
9 | int dist = levenSubstringIC_limited(s, "gazelle", 2); |
10 | ret dist == 0 ? "yes" : dist == 1 ? "maybe" : "no"; |
11 | } |
12 | |
13 | This function detects whether the word "gazelle" or a slight misspelling occurs in a line. |
14 | |
15 | For "hello gazelle", the function returns "yes". For "hello gazele", it returns "maybe"... and so on. It uses a variation of the Levenshtein distance algorithm. |
16 | |
17 | This is of course not the final function that we actually want, which will be much smarter and adapt to more cases. |
18 | |
19 | However, the coarse function is very useful anyway. |
20 | |
21 | -We can use it right away |
22 | -It is cheap to run |
23 | -It is predictable, reliable and easy to understand |
24 | -It will do what we want if the input is sufficiently well-formed |
25 | -It gets an intention across |
26 | -It can serve as a basis for an optimization algorithm that generates better code in its place |
27 | ...and more. |
28 | |
29 | We can bootstrap an AI system with a bunch of coarse procedures and then proceed to optimize it, be it manually or automatically. |
