Graphplan takes a least-commitment approach to planning, rather than sequentially choosing actions from an initial state, working forwards, or a goal state if working backwards. Satplan is an approach to planning where a planning problem is reduced to a Boolean satisfiability problem. A more flexible kind of problem-solving occurs when reasoning about what to do next occurs, rather than simply choosing one of the available actions. This kind of meta-level reasoning is used in Soar and in the BB1 blackboard architecture.
Symbolic regression is just messier and often depends on shady heuristics to work efficiently. Machine learning is an application of AI where statistical models perform specific tasks without using explicit instructions, relying instead on patterns and inference. Machine learning algorithms build mathematical models based on training data in order to make predictions. But neither the original, symbolic AI that dominated machine learning research until the late 1980s nor its younger cousin, deep learning, have been able to fully simulate the intelligence it’s capable of. The interpretation grammar defines the episode but is not observed directly and must be inferred implicitly. Set 1 has 14 input/output examples consistent with the grammar, used as Study examples for all MLC variants.
For scoring a particular human response y1, …, y7 by log-likelihood, MLC uses the same factorization as in equation (1). Performance was averaged over 200 passes through the dataset, each episode with different random query orderings as well as word and colour assignments. By feeding your data in .TXT or .CSV format into the program, you can immediately start searching for mathematical formulas that connect the variables.

Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages. Even though it is hard to generate symbolic models, they have some very desirable characteristics. For starters, a symbolic model is explicit, making it explainable and offering insight into the data. It is also simple, given that the optimization will actively try to keep the formulas as short as possible, which could potentially reduce the chances of overfitting the data. From a technical point of view, a symbolic model is very portable and can be easily implemented in any programming language, without the need for complex data structures.
In general, any number of additional single nesting levels can be introduced in the target terms relative to the source. By default, if no rule in a ruleset applied to source element s matches to s, s is copied unchanged to the result. Because rules are matched in the order of their listing in their ruleset, more specific rules should precede more general rules. A transitive partial order relation \(r1 \sqsubset r2\) can be defined on rules, which is true iff r1 is strictly more specific than r2. For example, if the LHS of r2 and r1 are equal, but r1 has stronger conditions than r2. The early pioneers of AI believed that “every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.” Therefore, symbolic AI took center stage and became the focus of research projects.
