darr1 <- RandomUnifArray(c(2,3,4))
darr2 <- RandomUnifArray(c(2,3,4))There are several settings in DelayedTensor.
First, the sparsity of the intermediate DelayedArray objects
calculated inside DelayedTensor is set by setSparse.
Note that the sparse mode is experimental.
Whether it contributes to higher speed and lower memory is quite dependent on the sparsity of the DelayedArray, and the current implementation does not recognize the block size, which may cause out-of-memory errors, when the data is extremely huge.
Here, we specify as.sparse as FALSE
(this is also the default value for now).
DelayedTensor::setSparse(as.sparse=FALSE)Next, the verbose message is suppressed by setVerbose.
This is useful when we want to monitor the calculation process.
Here we specify as.verbose as FALSE
(this is also the default value for now).
DelayedTensor::setVerbose(as.verbose=FALSE)The block size of block processing is specified by setAutoBlockSize.
When the sparse mode is off, all the functions of DelayedTensor
are performed as block processing,
in which each block vector/matrix/tensor is expanded to memory space
from on-disk file incrementally so as not to exceed the specified size.
Here, we specify the block size as 1E+8.
setAutoBlockSize(size=1E+8)## automatic block size set to 1e+08 bytes (was 1e+08)Finally, the temporal directory to store the intermediate HDF5 files during running DelayedTensor is specified by setHDF5DumpDir.
Note that in many systems the /var directory has the storage limitation, so if there is no enough space, user should specify the other directory.
# tmpdir <- paste(sample(c(letters,1:9), 10), collapse="")
# dir.create(tmpdir, recursive=TRUE))
tmpdir <- tempdir()
setHDF5DumpDir(tmpdir)These specified values are also extracted by each getter function.

2.1 Unfold/Fold Operations
Unfold (a.k.a. matricizing) operations are used to reshape a tensor into a matrix.
Figure 1: Unfold/Fold Operasions
In unfold, row_idx and col_idx are specified to set which modes are used
as the row/column.

There are some tensor specific product such as Hadamard product, Kronecker product, and Khatri-Rao product.
2.7.1 Hadamard Product
Suppose a tensor \(A \in \Re ^{I \times J}\) and a tensor \(B \in \Re ^{I \times J}\).
Hadamard product is defined as the element-wise product of \(A\) and \(B\).
Figure 7: Hadamard Product
Hadamard product can be extended to higher-order tensors.
\[ A \circ B = \begin{bmatrix} a_{11}b_{11} & a_{12}b_{12} & \cdots & a_{1J}b_{1J} \\ a_{21}b_{21} & a_{22}b_{22} & \cdots & a_{2J}b_{2J} \\ \vdots & \vdots & \ddots & \vdots \\ a_{I1}b_{I1} & a_{I2}b_{I2} & \cdots & a_{IJ}b_{IJ} \\ \end{bmatrix} \]
hadamard calculates Hadamard product of two DelayedArray
objects.
prod_h <- DelayedTensor::hadamard(darr1, darr2)
dim(prod_h)## [1] 2 3 4hadamard_list calculates Hadamard product of multiple
DelayedArray objects.
prod_hl <- DelayedTensor::hadamard_list(list(darr1, darr2))
dim(prod_hl)## [1] 2 3 42.7.2 Kronecker Product
Suppose a tensor \(A \in \Re ^{I \times J}\) and a tensor \(B \in \Re ^{K \times L}\).
Kronecker product is defined as all the possible combination of element-wise product and the dimensions of output tensor are \({IK \times JL}\).
Figure 8: Kronecker Product
Kronecker product can be extended to higher-order tensors.
\[ A \otimes B = \begin{bmatrix} a_{11}B & a_{12}B & \cdots & a_{1J}B \\ a_{21}B & a_{22}B & \cdots & a_{2J}B \\ \vdots & \vdots & \ddots & \vdots \\ a_{I1}B & a_{I2}B & \cdots & a_{IJ}B \\ \end{bmatrix} \]
kronecker calculates Kronecker product of two DelayedArray
objects.
prod_kron <- DelayedTensor::kronecker(darr1, darr2)
dim(prod_kron)## [1] 4 9 16kronecker_list calculates Kronecker product of multiple
DelayedArray objects.
prod_kronl <- DelayedTensor::kronecker_list(list(darr1, darr2))
dim(prod_kronl)## [1] 4 9 162.7.3 Khatri-Rao Product
Suppose a tensor \(A \in \Re ^{I \times J}\) and a tensor \(B \in \Re ^{K \times J}\).
Khatri-Rao product is defined as the column-wise Kronecker product and the dimensions of output tensor is \({IK \times J}\).
\[ A \odot B = \begin{bmatrix} a_{1} \otimes a_{1} & a_{2} \otimes a_{2} & \cdots & a_{J} \otimes a_{J} \\ \end{bmatrix} \]

Khatri-Rao product can only be used for 2D tensors (matrices).

objects.
