Overview

Package onnx provides wrapper functionality around the onnx.proto3.pb.go The goal is to provide a stable(ish) api around the proto file since the proto file is generated based on onnx.proto.

Attributes

A named attribute containing either singular float, integer, string, graph, and tensor values, or repeated float, integer, string, graph, and tensor values. An AttributeProto MUST contain the name field, and *only one* of the following content fields, effectively enforcing a C/C++ union equivalent.

Graphs

A graph defines the computational logic of a model and is comprised of a parameterized list of nodes that form a directed acyclic graph based on their inputs and outputs. This is the equivalent of the "network" or "graph" in many deep learning frameworks.

Models

ModelProto is a top-level file/container format for bundling a ML model and associating its computation graph with metadata.

The semantics of the model are described by the associated GraphProto's.

Nodes

Computation graphs are made up of a DAG of nodes, which represent what is commonly called a "layer" or "pipeline stage" in machine learning frameworks.

For example, it can be a node of type "Conv" that takes in an image, a filter tensor and a bias tensor, and produces the convolved output.

	// This field describes a graph to compute the initial tensors

	// networks are randomly initialized. To achieve that, for each tensor,
	// the user can put a random number operator such as RandomNormal or
	// RandomUniform in TrainingInfoProto.initialization.node and assign its
	// random output to the specific tensor using "initialization_binding".
	// This graph can also set the initializers in "algorithm" in the same
	// TrainingInfoProto; a use case is resetting the number of training
	// iteration to zero.
	//
	// By default, this field is an empty graph and its evaluation does not
	// produce any output. Thus, no initializer would be changed by default.
	Initialization *GraphProto `protobuf:"bytes,1,opt,name=initialization,proto3" json:"initialization,omitempty"`
	// This field represents a training algorithm step. Given required inputs,
	// it computes outputs to update initializers in its own or inference graph's
	// initializer lists. In general, this field contains loss node, gradient node,
	// optimizer node, increment of iteration count.
	//
	// An execution of the training algorithm step is performed by executing the
	// graph obtained by combining the inference graph (namely "ModelProto.graph")
	// and the "algorithm" graph. That is, the actual the actual
	// input/initializer/output/node/value_info/sparse_initializer list of
	// the training graph is the concatenation of
	// "ModelProto.graph.input/initializer/output/node/value_info/sparse_initializer"
	// and "algorithm.input/initializer/output/node/value_info/sparse_initializer"
	// in that order. This combined graph must satisfy the normal ONNX conditions.
	// Now, let's provide a visualization of graph combination for clarity.
	// Let the inference graph (i.e., "ModelProto.graph") be
	//    tensor_a, tensor_b -> MatMul -> tensor_c -> Sigmoid -> tensor_d

	//    tensor_a, tensor_b -> MatMul -> tensor_c -> Sigmoid -> tensor_d -> Add -> tensor_e
	//
	// Notice that an input of a node in the "algorithm" graph may reference the
	// output of a node in the inference graph (but not the other way round). Also, inference
	// node cannot reference inputs of "algorithm". With these restrictions, inference graph
	// can always be run independently without training information.
	//
	// By default, this field is an empty graph and its evaluation does not
	// produce any output. Evaluating the default training step never
	// update any initializers.

	// x = x - r * g
	//
	// where "x" is the optimized tensor, "r" stands for learning rate, and "g" is
	// gradient of "x" with respect to a chosen loss. To avoid adding assignments
	// into the training graph, we split the update equation into
	//
	// y = x - r * g
	// x = y
	//
	// The user needs to save "y = x - r * g" into TrainingInfoProto.algorithm. To
	// tell that "y" should be assigned to "x", the field "update_binding" may

	//
	// The initializers appears as keys in "update_binding" are considered
	// mutable variables. This implies some behaviors
	// as described below.
	//
	//  1. We have only unique keys in all "update_binding"s so that two
	//     variables may not have the same name. This ensures that one
	//     variable is assigned up to once.
	//  2. The keys must appear in names of "ModelProto.graph.initializer" or
	//     "TrainingInfoProto.algorithm.initializer".
	//  3. The values must be output names of "algorithm" or "ModelProto.graph.output".
	//  4. Mutable variables are initialized to the value specified by the
	//     corresponding initializer, and then potentially updated by
	//     "initializer_binding"s and "update_binding"s in "TrainingInfoProto"s.
	//
	// This field usually contains names of trainable tensors
	// (in ModelProto.graph), optimizer states such as momentums in advanced
	// stochastic gradient methods (in TrainingInfoProto.graph),
	// and number of training iterations (in TrainingInfoProto.graph).
	//
	// By default, this field is empty and no initializer would be changed

Training information TrainingInfoProto stores information for training a model. In particular, this defines two functionalities: an initialization-step and a training-algorithm-step. Initialization resets the model back to its original state as if no training has been performed. Training algorithm improves the model based on input data.

The semantics of the initialization-step is that the initializers in ModelProto.graph and in TrainingInfoProto.algorithm are first initialized as specified by the initializers in the graph, and then updated by the "initialization_binding" in every instance in ModelProto.training_info.

The field "algorithm" defines a computation graph which represents a training algorithm's step. After the execution of a TrainingInfoProto.algorithm, the initializers specified by "update_binding" may be immediately updated. If the targeted training algorithm contains consecutive update steps (such as block coordinate descent methods), the user needs to create a TrainingInfoProto for each step.
