Examples with ConstantTensor com.yahoo.tensor.functions.ConstantTensor used on opensource projects

Example 1 with ConstantTensor

use of com.yahoo.tensor.functions.ConstantTensor in project vespa by vespa-engine.

the class TensorFunctionBenchmark method dotProduct.

private double dotProduct(Tensor tensor, List<Tensor> tensors) {
    double largest = Double.MIN_VALUE;
    TensorFunction dotProductFunction = new Reduce(new Join(new ConstantTensor(tensor), new VariableTensor("argument"), (a, b) -> a * b), Reduce.Aggregator.sum).toPrimitive();
    MapEvaluationContext context = new MapEvaluationContext();
    for (Tensor tensorElement : tensors) {
        // tensors.size() = 1 for larger tensor
        context.put("argument", tensorElement);
        double dotProduct = dotProductFunction.evaluate(context).asDouble();
        if (dotProduct > largest) {
            largest = dotProduct;
        }
    }
    return largest;
}

Example 2 with ConstantTensor

use of com.yahoo.tensor.functions.ConstantTensor in project vespa by vespa-engine.

the class TensorTestCase method dotProduct.

private double dotProduct(Tensor tensor, List<Tensor> tensors) {
    double sum = 0;
    TensorFunction dotProductFunction = new Reduce(new Join(new ConstantTensor(tensor), new VariableTensor("argument"), (a, b) -> a * b), Reduce.Aggregator.sum).toPrimitive();
    MapEvaluationContext context = new MapEvaluationContext();
    for (Tensor tensorElement : tensors) {
        // tensors.size() = 1 for larger tensor
        context.put("argument", tensorElement);
        // System.out.println("Dot product of " + tensor + " and " + tensorElement + ": " + dotProductFunction.evaluate(context).asDouble());
        sum += dotProductFunction.evaluate(context).asDouble();
    }
    return sum;
