46c887b77e genericvector: Fix minimum size 
Commit 907de5995f tried to improve
GenericVector, but missed a case where vectors with less than
kDefaultVectorSize were allocated. This resulted in additional
alloc / free operations.

Commit a28b2a033d (before memory optimization)
oem 0: total heap usage: 739,238 allocs, 739,237 frees, 161,699,214 bytes allocated
oem 1: total heap usage: 690,182 allocs, 690,175 frees, 144,470,400 bytes allocated
oem 2: total heap usage: 728,213 allocs, 728,206 frees, 182,885,824 bytes allocated

Commit fd3f8f9b2d without genericvector change
oem 0: total heap usage: 738,980 allocs, 738,979 frees, 161,697,150 bytes allocated
oem 1: total heap usage: 690,182 allocs, 690,175 frees, 144,470,400 bytes allocated
oem 2: total heap usage: 728,213 allocs, 728,206 frees, 182,885,824 bytes allocated
=> Improvements for oem 0, no change for oem 1 and oem 2.

Commit fd3f8f9b2d
oem 0: total heap usage: 772,648 allocs, 772,647 frees, 160,083,901 bytes allocated
oem 1: total heap usage: 748,591 allocs, 748,584 frees, 143,581,672 bytes allocated
oem 2: total heap usage: 764,796 allocs, 764,789 frees, 181,212,197 bytes allocated
=> Less bytes allocated, but more allocs / frees = bad for performance.

Commit fd3f8f9b2d with this patch
oem 0: total heap usage: 677,537 allocs, 677,536 frees, 160,444,634 bytes allocated
oem 1: total heap usage: 653,812 allocs, 653,805 frees, 143,423,008 bytes allocated
oem 2: total heap usage: 670,029 allocs, 670,022 frees, 181,517,760 bytes allocated
=> Improvements for all three cases.

It must also include man_MANS – otherwise make tries to build the
man pages also in non maintainer mode without having a rule for that.

This fixes commit 2794410c9b.

83588bc7a1 Classify: Avoid unneeded new / delete operations 
Both class variables BaselineCutoffs and CharNormCutoffs were pointers
to fixed size arrays which were allocated in the constructor and
deallocated in the destructor. These two extra allocations and two
extra deallocations can be avoided.

1cc511188d Added extra Init that takes a memory buffer or a filereader function pointer to enable read of traineddata from memory or foreign file systems. Updated existing readers to use TFile API instead of FILE. This does not yet add big-endian capability to LSTM, but it is very easy from here. 2017-04-27 15:48:23 -07:00
