For +each cell, it had the option to go up, down, left or right (unless it came from +there). The input consists of these decisions, while the desired output is an +annotation of the snake from 0 (head) to 9 (tail). See the plots for an +example. + +As input features we use a 3x3 window around each pixel (and pad with background +where necessary). We code the five different input colors (for up, down, left, right, +background) using a one-hot encoding. This is a rather naive approach, not using any +information about the dataset (other than that it is a 2d grid). + +The task can not be solved using the simple DirectionalGridCRF - which can only +infer head and tail (which are also possible to infer just from the unary +features). If we add edge-features that contain the features of the nodes that are +connected by the edge, the CRF can solve the task. + +From an inference point of view, this task is very hard. QPBO move-making is +not able to solve it alone, so we use the relaxed AD3 inference for learning. + +PS: This example runs a bit (5 minutes on 12 cores, 20 minutes on one core for me). +But it does work as well as Decision Tree Fields ;) + + + + JL Meunier - January 2017 + + Developed for the EU project READ.

Because they do not form a valid 10-long snake, as 1 pixel has a wrong colour destroying the continuity of the snake. + +The original task remains but is more difficult: some non-blue pixels are now labelled 'background'.

See in next section. + + +## CRF Graph with Nodes of Different Nature +Pystruct CRF graphs assumes that the nodes of the graph all have the same nature. In consequence, all nodes share the same weights and the same set of possible labels. Similarly, all edges have the same nature and share the same edge weights. +This was a limitation with regards to our needs (for a Document Understanding task). So we propose a new CRF model called *NodeTypeEdgeFeatureGraphCRF*. + +*NodeTypeEdgeFeatureGraphCRF* supports multiple node of multiple nature, which we call **node types**. Each type has its own weights and own set of possible labels. Similarly, edges have different nature depending on the type of their sources and target-nodes. In a graph with N types, there are N^2 types of edges. + +*NodeTypeEdgeFeatureGraphCRF* generalizes *EdgeFeatureGraphCRF*, so edges have features.

This is still ad3 code, but working on a binarized graph. - -For learning I mostly used the __*OneSlackSSVM*__ learner, which requires to install **cvxopt** as well. - -### Python libraries: -> pip install install numpy scipy cvxopt pyqpbo scikit-learn nose pytest - -### For AD3: - * get it from https://github.com/andre-martins/AD3 - * install it: - -> python setup.py install - -### For Pystruct+: - * get the source code from https://github.com/jlmeunier/pystruct - * compile and install: - -> python setup.py install - -## Tests -To test your install, run the test of the new CRF model: -> python pystruct/tests/test_models/test_node_type_edge_feature_graph_crf.py - -(You should see a "OK" displayed at the end of the script execution.) - -## Example -Building on the [Snakes](https://pystruct.github.io/auto_examples/plot_snakes.html#sphx-glr-auto-examples-plot-snakes-py) example, there is now a new example called "HiddenSnakes". (Code in examples/plot_hidden_short_snakes_typed.py ) - -The idea is that some picture do not contain any snake despite 10 pixels have a Snake body colour. Why? Because they do not form a valid 10-long snake, as 1 pixel has a wrong colour destroying the continuity of the snake. - -The original task remains but is more difficult: some non-blue pixels are now labelled 'background'. An additional task consists in labeling the picture as Snake or NoSnake. - -This double task is solved by the use of an additional type of node that represents the picture itself, with 7 simplistic features. There are additional edges, from each pixel to the picture node. That's all. And it improves a lot from the results of the *EdgeFeatureGraphCRF*-based model. - -In addition, we injected some more domain knowledge to illustrate the use of the hard logic constraints. In this case we enforce *at most one pixel of label L per picture, for L in [1, 10]*. This gives an extra accuracy bonus. - -## Prediction with Hard-Logic Constraints - -You can now pass a __list of logical constraints__ to the predict method, with a *constraints=* named parameter. - - Each constraint is tuple like *( operator, nodes, labels, negated )* - where: - - *operator* is one of 'XOR' 'XOROUT' 'ATMOSTONE' 'OR' 'OROUT' 'ANDOUT' 'IMPLY' - - *nodes* is the list of the index of each node involved in this constraint - - *labels* is the list of node label. If the labels are the same for all nodes, you can pass it directly as a scalar value. - - *negated* is a list of boolean indicating if the corresponding argument must be negated. Again, if all values are the same, pass a single boolean value instead of a list. - -The operators whose name ends with 'OUT' impose that the operator applied on the all-but-last arguments yields the truth value of the last one. ->For instance XOROUT(a,b,c) <=> XOR(a,b) = c - -When used jointly with the new *NodeTypeEdgeFeatureGraphCRF* model, the structure of the constraints list slightly differs. See in next section. - - -## CRF Graph with Nodes of Different Nature -Pystruct CRF graphs assumes that the nodes of the graph all have the same nature. In consequence, all nodes share the same weights and the same set of possible labels. Similarly, all edges have the same nature and share the same edge weights. -This was a limitation with regards to our needs (for a Document Understanding task). So we propose a new CRF model called *NodeTypeEdgeFeatureGraphCRF*. - -*NodeTypeEdgeFeatureGraphCRF* supports multiple node of multiple nature, which we call **node types**. Each type has its own weights and own set of possible labels. Similarly, edges have different nature depending on the type of their sources and target-nodes. In a graph with N types, there are N^2 types of edges. - -*NodeTypeEdgeFeatureGraphCRF* generalizes *EdgeFeatureGraphCRF*, so edges have features. NOTE: I think that you can mimics the absence opf feature on edges (as in *GraphCRF* model) by specifying one feature per edge, whose value is 1 for all edges. - -**This extension has an impact on:** - * the constructor - * the structure of the label weights, if not uniform - * the structure of the Xs - * the values in Ys - * the structure of the optional constraint list at prediction - -### Class Constructor -You need now to define the number of node types and the number of features per type (of node, and of edge) when instantiating *NodeTypeEdgeFeatureGraphCRF*. - - def __init__(self - , n_types #how many node type? - , l_n_states #how many labels per node type? - , l_n_features #how many features per node type? - , a_n_edge_features #how many features per edge type?

The index of the nodes in each type starts at 0. -* *l_edge_features* is a list of length *n_types*^2. It contains the features of the edges for each pair of types, in same order as in previous parameter. Each item is an array of shape (*n_typ_edges*, *n_typ_edge_features*). if *n_typ_edge_features* is 0, then *n_typ_edges* should be 0 as well for all instances of graph! If you want an edge without features, set *n_typ_edge_features* to 1 and pass 1.0 as feature for all edges (of that type). +The goal of PyStruct is to provide a well-documented tool for researchers as well as non-experts +to make use of structured prediction algorithms. +The design tries to stay as close as possible to the interface and conventions +of [scikit-learn](http://scikit-learn.org). -Each *Y* remains a vector array.

(Code in examples/plot_hidden_short_snakes_typed.py ) + +The idea is that some picture do not contain any snake despite 10 pixels have a Snake body colour. Why? Because they do not form a valid 10-long snake, as 1 pixel has a wrong colour destroying the continuity of the snake. + +The original task remains but is more difficult: some non-blue pixels are now labelled 'background'. An additional task consists in labeling the picture as Snake or NoSnake. + +This double task is solved by the use of an additional type of node that represents the picture itself, with 7 simplistic features. There are additional edges, from each pixel to the picture node. That's all. And it improves a lot from the results of the *EdgeFeatureGraphCRF*-based model. + +In addition, we injected some more domain knowledge to illustrate the use of the hard logic constraints. In this case we enforce *at most one pixel of label L per picture, for L in [1, 10]*. This gives an extra accuracy bonus. + +## Prediction with Hard-Logic Constraints + +You can now pass a __list of logical constraints__ to the predict method, with a *constraints=* named parameter. + + Each constraint is tuple like *( operator, nodes, labels, negated )* + where: + - *operator* is one of 'XOR' 'XOROUT' 'ATMOSTONE' 'OR' 'OROUT' 'ANDOUT' 'IMPLY' + - *nodes* is the list of the index of each node involved in this constraint + - *labels* is the list of node label. If the labels are the same for all nodes, you can pass it directly as a scalar value. + - *negated* is a list of boolean indicating if the corresponding argument must be negated. Again, if all values are the same, pass a single boolean value instead of a list. + +The operators whose name ends with 'OUT' impose that the operator applied on the all-but-last arguments yields the truth value of the last one. +>For instance XOROUT(a,b,c) <=> XOR(a,b) = c + +When used jointly with the new *NodeTypeEdgeFeatureGraphCRF* model, the structure of the constraints list slightly differs. See in next section. + + +## CRF Graph with Nodes of Different Nature +Pystruct CRF graphs assumes that the nodes of the graph all have the same nature. In consequence, all nodes share the same weights and the same set of possible labels. Similarly, all edges have the same nature and share the same edge weights. +This was a limitation with regards to our needs (for a Document Understanding task). So we propose a new CRF model called *NodeTypeEdgeFeatureGraphCRF*. + +*NodeTypeEdgeFeatureGraphCRF* supports multiple node of multiple nature, which we call **node types**. Each type has its own weights and own set of possible labels. Similarly, edges have different nature depending on the type of their sources and target-nodes. In a graph with N types, there are N^2 types of edges. + +*NodeTypeEdgeFeatureGraphCRF* generalizes *EdgeFeatureGraphCRF*, so edges have features. NOTE: I think that you can mimics the absence opf feature on edges (as in *GraphCRF* model) by specifying one feature per edge, whose value is 1 for all edges. + +**This extension has an impact on:** + * the constructor + * the structure of the label weights, if not uniform + * the structure of the Xs + * the values in Ys + * the structure of the optional constraint list at prediction + +### Class Constructor +You need now to define the number of node types and the number of features per type (of node, and of edge) when instantiating *NodeTypeEdgeFeatureGraphCRF*. + + def __init__(self + , n_types #how many node type? + , l_n_states #how many labels per node type? + , l_n_features #how many features per node type? + , a_n_edge_features #how many features per edge type?

Each of its elements contains an array of shape (*n_typ_edge, 2) defining the edges from nodes of type *i* to nodes of type *j*, with *i* and *j* in [0, *n_types*-1], *j* being the secondary index (inner loop). The index of the nodes in each type starts at 0. +* *l_edge_features* is a list of length *n_types*^2. It contains the features of the edges for each pair of types, in same order as in previous parameter. Each item is an array of shape (*n_typ_edges*, *n_typ_edge_features*). if *n_typ_edge_features* is 0, then *n_typ_edges* should be 0 as well for all instances of graph! If you want an edge without features, set *n_typ_edge_features* to 1 and pass 1.0 as feature for all edges (of that type). + +Each *Y* remains a vector array. While the label could start at 0 for all types, we have chosen not to do so. (Essentially,to make clear that types do not blend into each other, which is clear when you show a confusion matrix). So the labels of the first type start at 0, while labels of next type starts right after the value of the last label of previous type. +*NodeTypeEdgeFeatureGraphCRF* provides 2 convenience methods: +* *flattenY*( [ [2,0,0], [3,3,4] ] ) --> [ 2,0,0, 5,5,7] (assuming type 0 has 3 labels) +* *unflattenY*(Xs, [ 2,0,0, 5,5,7] ) --> [ [2,0,0], [3,3,4] ] (you'll also need to pass the Xs) + +### Constraints on Multitype Graphs +As for the Xs and Ys, the constraint must be partitioned by type. + + The constraints must be a list of tuples like: + +Either + + ( *operator*, *l_nodes*, *l_labels*, *l_negated* ) + with operator being one 'XOR' 'ATMOSTONE' 'OR' + +Or + + ( *operator*, *l_nodes*, *l_labels*, *l_negated* , (*type*, *node*, *label*, *negated*)) + with operator being one 'XOROUT' 'OROUT' 'ANDOUT' 'IMPLY' + +- *l_nodes* is a list of nodes per type.

+============================================== +Conditional Interactions on the Snakes Dataset +============================================== + +This is a variant of plot_snakes.py + +Snake are hidding, so we have 2 tasks: +- determining if a snake is in the picture, +- identifying its head to tail body. + +We use the NodeTypeEdgeFeatureGraphCRF class with 2 type of nodes. + +HERE WE GENERATE THE SNAKES AT RANDOM INSTEAD OF USING THE SNAKE DATASET + + +This example uses the snake dataset introduced in +Nowozin, Rother, Bagon, Sharp, Yao, Kohli: Decision Tree Fields ICCV 2011 + +This dataset is specifically designed to require the pairwise interaction terms +to be conditioned on the input, in other words to use non-trival edge-features. + +The task is as following: a "snake" of length ten wandered over a grid. For +each cell, it had the option to go up, down, left or right (unless it came from +there). The input consists of these decisions, while the desired output is an +annotation of the snake from 0 (head) to 9 (tail). See the plots for an +example. + +As input features we use a 3x3 window around each pixel (and pad with background +where necessary). We code the five different input colors (for up, down, left, right, +background) using a one-hot encoding. This is a rather naive approach, not using any +information about the dataset (other than that it is a 2d grid). + +The task can not be solved using the simple DirectionalGridCRF - which can only +infer head and tail (which are also possible to infer just from the unary +features). If we add edge-features that contain the features of the nodes that are +connected by the edge, the CRF can solve the task. + +From an inference point of view, this task is very hard. QPBO move-making is +not able to solve it alone, so we use the relaxed AD3 inference for learning. + +PS: This example runs a bit (5 minutes on 12 cores, 20 minutes on one core for me). +But it does work as well as Decision Tree Fields ;) + + + + JL Meunier - January 2017 + + Developed for the EU project READ.

(Code in examples/plot_hidden_short_snakes_typed.py ) + +The idea is that some picture do not contain any snake despite 10 pixels have a Snake body colour. Why? Because they do not form a valid 10-long snake, as 1 pixel has a wrong colour destroying the continuity of the snake. + +The original task remains but is more difficult: some non-blue pixels are now labelled 'background'. An additional task consists in labeling the picture as Snake or NoSnake. + +This double task is solved by the use of an additional type of node that represents the picture itself, with 7 simplistic features. There are additional edges, from each pixel to the picture node. That's all. And it improves a lot from the results of the *EdgeFeatureGraphCRF*-based model. + +In addition, we injected some more domain knowledge to illustrate the use of the hard logic constraints. In this case we enforce *at most one pixel of label L per picture, for L in [1, 10]*.

See in next section. + + +## CRF Graph with Nodes of Different Nature +Pystruct CRF graphs assumes that the nodes of the graph all have the same nature. In consequence, all nodes share the same weights and the same set of possible labels. Similarly, all edges have the same nature and share the same edge weights. +This was a limitation with regards to our needs (for a Document Understanding task). So we propose a new CRF model called *NodeTypeEdgeFeatureGraphCRF*. + +*NodeTypeEdgeFeatureGraphCRF* supports multiple node of multiple nature, which we call **node types**. Each type has its own weights and own set of possible labels. Similarly, edges have different nature depending on the type of their sources and target-nodes. In a graph with N types, there are N^2 types of edges. + +*NodeTypeEdgeFeatureGraphCRF* generalizes *EdgeFeatureGraphCRF*, so edges have features. NOTE: I think that you can mimics the absence opf feature on edges (as in *GraphCRF* model) by specifying one feature per edge, whose value is 1 for all edges. + +**This extension has an impact on:** + * the constructor + * the structure of the label weights, if not uniform + * the structure of the Xs + * the values in Ys + * the structure of the optional constraint list at prediction + +### Class Constructor +You need now to define the number of node types and the number of features per type (of node, and of edge) when instantiating *NodeTypeEdgeFeatureGraphCRF*. + + def __init__(self + , n_types #how many node type? + , l_n_states #how many labels per node type? + , l_n_features #how many features per node type? + , a_n_edge_features #how many features per edge type?

Each of its elements contains an array of shape (*n_typ_edge, 2) defining the edges from nodes of type *i* to nodes of type *j*, with *i* and *j* in [0, *n_types*-1], *j* being the secondary index (inner loop). The index of the nodes in each type starts at 0. +* *l_edge_features* is a list of length *n_types*^2. It contains the features of the edges for each pair of types, in same order as in previous parameter. Each item is an array of shape (*n_typ_edges*, *n_typ_edge_features*). if *n_typ_edge_features* is 0, then *n_typ_edges* should be 0 as well for all instances of graph! If you want an edge without features, set *n_typ_edge_features* to 1 and pass 1.0 as feature for all edges (of that type). + +Each *Y* remains a vector array. While the label could start at 0 for all types, we have chosen not to do so. (Essentially,to make clear that types do not blend into each other, which is clear when you show a confusion matrix). So the labels of the first type start at 0, while labels of next type starts right after the value of the last label of previous type. +*NodeTypeEdgeFeatureGraphCRF* provides 2 convenience methods: +* *flattenY*( [ [2,0,0], [3,3,4] ] ) --> [ 2,0,0, 5,5,7] (assuming type 0 has 3 labels) +* *unflattenY*(Xs, [ 2,0,0, 5,5,7] ) --> [ [2,0,0], [3,3,4] ] (you'll also need to pass the Xs) + +### Constraints on Multitype Graphs +As for the Xs and Ys, the constraint must be partitioned by type. + + The constraints must be a list of tuples like: + +Either + + ( *operator*, *l_nodes*, *l_labels*, *l_negated* ) + with operator being one 'XOR' 'ATMOSTONE' 'OR' + +Or + + ( *operator*, *l_nodes*, *l_labels*, *l_negated* , (*type*, *node*, *label*, *negated*)) + with operator being one 'XOROUT' 'OROUT' 'ANDOUT' 'IMPLY' + +- *l_nodes* is a list of nodes per type.
