+# Neural-Guided Symbolic Regression with Asymptotic Constraints
+
+This directory contains reference code for paper
+"Neural-Guided Symbolic Regression with Asymptotic Constraints"
+
+https://arxiv.org/abs/1901.07714
+
+## Dataset
+
+`grammar/univariate_one_constant_grammar.txt` contains grammar production rules
+to generate univariate expressions.
+
+Folder `data` contains datasets of rational expressions used in the paper.
+Each CSV contains four columns:
+`expression_string`,
+`simplified_expression_string`,
+`leading_at_0`,
+`leading_at_inf`
+
+We define the complexity of an expression as
+
+M = |leading power at 0| + |leading power at inf|
+
+
+### `train.csv`
+
+28837 expressions with M <= 4. This dataset is used for training the neural
+network model and generation of empirical distribution for baseline models.
+`train.tfrecords` contains data in `train.csv`.
+
+### `eval.csv`
+
+4095 expressions with M <= 4. This dataset is used for validation in neural
+network training.
+`eval.tfrecords` contains data in `eval.csv`.
+
+### `holdout_m_leq_4.csv`
+
+2050 expressions with M <= 4.
+
+### `holdout_m_5.csv`
+
+1000 expressions with M = 5.
+
+### `holdout_m_6.csv`
+
+1200 expressions with M = 6.
+
+
+`holdout_m_leq_4.csv`, `holdout_m_5.csv` and `holdout_m_6.csv` are used to
+evaluate different symbolic regression methods.
+
+## Metrics
+
+The code to evaluate success, L1-distance, syntactic novelty and
+semantic novelty:
+
+`utils/expression_generalization_metrics.py`
+
+## Expression Generating Neural Network and Baseline Models
+
+The reference code to train the neural network is in folder `models`.
+
+Train neural network (NN):
+
+```
+python -m neural_guided_symbolic_regression.models.run_partial_sequence_model \
+--hparams=$(pwd)/neural_guided_symbolic_regression/models/config/neural_network.json \
+--is_chief \
+--model_dir=/tmp/neural_guided_symbolic_regression/example_run
+```
+
+Train neural network no condition (NNNC):
+
+```
+python -m neural_guided_symbolic_regression.models.run_partial_sequence_model \
+--hparams=$(pwd)/neural_guided_symbolic_regression/models/config/neural_network_no_condition.json \
+--is_chief \
+--model_dir=/tmp/neural_guided_symbolic_regression/example_run
+```
+
+The code to generate empirical distribution baseline models:
+
+`utils/generate_empirical_distribution_df.py`
+
+## Symbolic Regression Methods
+
+### Monte Carlo Tree Search
+
+(Neural-Guided) Monte Carlo Tree Search is implemented in folder `mcts`.
+`models/mcts.py` defines policy and reward for the symbolic regression tasks
+in the paper.
+
+### Evolutionary Algorithm
+
+Evolutionary algorithm is implemented in `models/evolutionary.py`.

+  Inspired from the encoding and decoding methods in

+  S -> S '+' T
+  S -> S '-' T
+  S -> S '*' T
+  S -> S '/' T
+  S -> T
+  T -> 'a'
+  T -> 'b'
+
+  Among all the 7 grammar production rules, the only allowed production rules
+  for current state 'a + T' are T -> 'a' and T -> 'b', because the next

+"""Monte Carlo Tree Search (MCTS) algorithm.
+
+This module defines the node and operations for MCTS.
+
+Introduction to Monte Carlo Tree Search:
+https://en.wikipedia.org/wiki/Monte_Carlo_tree_search
+
+Each trial of Monte Carlo tree search consists of four steps:
+
+* Selection: Start from root and select successive child nodes down to a leaf
+    node.
+* Expansion: Unless the selected leaf node is terminal state, expand the
+    selected node.
+* Simulation: Start from the current state in the node, recursively simulate to
+    the next state until terminal state. Get the reward score from the terminal
+    state. This step is sometimes also called rollout. It is worth to note that
+    another choice is to use a heuristic function or a neural network to
+    evaluate the reward score of a non-terminal state without rollout.
+    For example,
+
+    "Mastering the game of Go with deep neural networks and tree search",
+    Nature 2016
+    Used a mix of rollout and reward directly from neural network as the
+    simulation result.
+
+    "Mastering the game of Go without human knowledge", Nature 2017
+    Used a neural network alone to get the simulation result without rollout.
+
+* Backpropagation: Update the reward score from the leaf node started the
+    simulation to the parent node recursively.

+"""Library of expression generalization metrics.
+
+Metrics are evaluated per condition (i.e., a given set of symbolic properties
+and their values). We are interested in the following metrics:
+ * Success rate: If we generate, let's say 100, expressions, how many of
+   them satisfy the condition. In formula, it is number of expressions
+   satisfying the condition / number of expressions generated.
+ * Syntactic novelty rate: Among all expressions satisfying the condition, how
+   many of them haven't been seen in the training set. In formula, it is number
+   of unseen expressions satisfying the condition / number of expressions
+   satisfying the condition. Note that 'x' and '( x )' are syntactically
+   different. So if 'x' appears in generation, and '( x )' appears in train, 'x'
+   is still regarded as a syntactic novelty.
+ * Semantic novelty rate: Among all expressions satisfying the condition, how
+   many expressions having simplified expressions that haven't been seen in the
+   simplified expressions derived from the training set. In formula, it is
+   number of expressions with unseen simplified expressions satisfying the

+called partial information) to determine the next production rule.
+
+Each row of the dataframe contains a string of partial sequence indices (or tail
+of it), and the conditions of the complete sequence (such as leading power at
+zero and leading power at inf). These are placed as multi-indices of the
+dataframe. The columns of the dataframe are the probabilities of the next
+production rule.
+
+Here is an example of the first kind of dataframe:
+partial_sequence_indices  leading_at_0  leading_at_inf  0  1  2   ...
+        1_4_3_5                -1            -1         0  0  0.5 ...
+
+Here is an example of the second kind of dataframe with tail_length=2:
+tail_partial_sequence_indices  leading_at_0  leading_at_inf  0  1  2   ...
+            3_5                     -1            -1         0  0  0.5 ...
+
+How is the dataframe computed:
+For each given string of partial sequence indices (or tail of it) and
+conditions, find all the matches from the training set. This gives a number of
+next production rules. Compute the empirical distribution of these production
+rules. Note that for the tail partial sequence, the next production rule mask of
+the entire sequence is needed to ensure the validity of the proposed next
+production rule.
