Report Description: Basic Test

Serialization

This run will demonstrate the layer’s JSON serialization, and verify deserialization integrity.

Raw Json

Code from SerializationTest.java:84 executed in 0.00 seconds:

    final JsonObject json = layer.getJson();
    final NNLayer echo = NNLayer.fromJson(json);
    if (echo == null) throw new AssertionError("Failed to deserialize");
    if (layer == echo) throw new AssertionError("Serialization did not copy");
    if (!layer.equals(echo)) throw new AssertionError("Serialization not equal");
    return new GsonBuilder().setPrettyPrinting().create().toJson(json);

Returns:

    {
      "class": "com.simiacryptus.mindseye.layers.java.AvgImageBandLayer",
      "id": "e3e08b74-dd4d-41d9-a529-c223055c47b8",
      "isFrozen": false,
      "name": "AvgImageBandLayer/e3e08b74-dd4d-41d9-a529-c223055c47b8"
    }

Wrote Model to AvgImageBandLayer_Basic.json; 209 characters

Example Input/Output Pair

Display input/output pairs from random executions:

Code from ReferenceIO.java:69 executed in 0.00 seconds:

    final SimpleEval eval = SimpleEval.run(layer, inputPrototype);
    return String.format("--------------------\nInput: \n[%s]\n--------------------\nOutput: \n%s\n--------------------\nDerivative: \n%s",
                         Arrays.stream(inputPrototype).map(t -> t.prettyPrint()).reduce((a, b) -> a + ",\n" + b).get(),
                         eval.getOutput().prettyPrint(),
                         Arrays.stream(eval.getDerivative()).map(t -> t.prettyPrint()).reduce((a, b) -> a + ",\n" + b).get());

Returns:

    Input: 
    [[
    	[ [ -0.184, 0.34, -0.268 ], [ -0.656, 1.852, 1.72 ] ],

    ]]

    Output:

    ]

Batch Execution

Most layers, including this one, should behave the same no matter how the items are split between batches. We verify this:

Code from BatchingTester.java:113 executed in 0.00 seconds:

    return test(reference, inputPrototype);

Returns:
