Select a dataset and provide batched data/label pairs.
|
||||
|
||||
1. In-memory datasets, stream from disk.
|
||||
2. Train/valid/test set marking.
|
||||
3. K-fold rotation.
|
||||
2. Conversion from source data type to batch data type.
|
||||
3. One-hot encoding.
|
||||
4. Shuffling.
|
||||
|
||||
Options:
|
||||
1. Read all data into memory (otherwise stream from disk -require async reading)
|
||||
2. data type conversion on-load vs on-batch.
|
||||
3. one-hot encoding on-load vs on-batch.
|
||||
4. shuffle
|
||||
a. from streaming input buffer.
|
||||
b. in memory
|
||||
c. on batch
|
||||
|
||||
|
||||
Source Driver:
|
||||
label() // string label of this source
|
||||
open(cfg) // open the source
|
||||
close() // close the source
|
||||
get_info() // get the source dim and type info
|
||||
read(N,dst_t,dataBuf,labelBuf);// read a block of N examples and cvt to type dst_t
|
||||
|
||||
Implementation:
|
||||
The only difference between streaming from disk and initial load to memory is that
|
||||
stream-from-disk fills a second copy of the in-memory data structure.
|
||||
|
||||
All set marking, both RVT and K-Fold, happen on the in-memory data structure after it is populated.
|
||||
|
||||
Shuffling happens on the in-memory data structure after it is populated.
|
||||
If there is no data conversion or one-hot conversion on batch output then shuffling moves elements in-memory otherwise
|
||||
the shuffle index vector is used as a lookup during the output step.
|
||||
|
||||
If K-Fold segmentation is used with a streaming dataset then the k-fold index must persist
|
||||
between fold selection passes.
