1. package dsl

   

   Domain specific language for generating Bundle.ML models.

   Domain specific language for generating Bundle.ML models.

   DSL provides objects for generating various Bundle.ML objects.

   ml.combust.bundle.dsl.Bundle - Stores the name, version, serialization format, list of attributes, and list of root nodes in the bundle graph.

   ml.combust.bundle.dsl.Node - A node for transforming data in the model graph. Nodes have a unique name within a Bundle.ML graph and are responsible for piping inputs to a model and outputs from a model to the rest of the graph via sockets. Sockets map a field name in the graph to a specific port in a model.

   A model can have input ports and output ports. An example would be a StringIndexer node named "my_string_indexer" that indexes the input field "my_string_label" to the output field "my_double_label". There are two sockets for this node, one that maps the "my_string_label" field to the "input" port of the model and another socket that maps the "output" port of the model to the "my_double_label" field.

   ml.combust.bundle.dsl.Model - A model operation that transforms data within the graph. Models have an op name that define the type of model. For instance, the op name could be "string_indexer", "linear_regression", or "random_forest_regression". In addition to the op name of the model, all of the required attributes, such as coefficients and intercepts ,for executing the model are stored here.

   ml.combust.bundle.dsl.Attribute - Attributes are used to store values for ml.combust.bundle.dsl.Models and ml.combust.bundle.dsl.Bundles. They contain a name, a ml.bundle.DataType.DataType and a ml.combust.bundle.dsl.Value.

   ml.combust.bundle.dsl.Value - Values store concrete data for an ml.combust.bundle.dsl.Attribute. You can store basic data like strings, doubles, longs and booleans, tensors of any dimension, custom data types, and lists of any depth and data type.

   ml.combust.bundle.dsl.AttributeList - Stores a set of ml.combust.bundle.dsl.Attributes.

   ml.combust.bundle.dsl.Shape - Stores the map of graph input/output fields to model inputs and outputs.

2. package json

   

   Provides traits and objects for handling Bundle.ML JSON data with Spray JSON.

   Provides traits and objects for handling Bundle.ML JSON data with Spray JSON.

   Overview

   ml.combust.bundle.json.JsonSupport provides all spray.json.JsonFormat formats. Either import or mixin the formats into scope in order to use them.

   scala> import ml.bundle.json.JsonSupport._
          import spray.json._
          import ml.bundle._
          val tt = TensorType.TensorType(BasicType.BasicType.DOUBLE, Seq(-1))
          val underlying = DataType.DataType.Underlying.Tensor(tt)
          val dataType = DataType.DataType(underlying)
   scala> val jsonString = dataType.toJson.prettyPrint
   jsonString: String =
   {
     "type": "tensor",
     "tensor": {
     "base": "double",
     "dimensions": [-1]
     }
   }
