| b9b6ccd | Amit Agarwal | 07 January 2016, 19:32:15 UTC | Made inclusion of quantized gradient aggregation header compile-time conditional.

| 0c9acd2 | Frank Seide | 06 January 2016, 03:42:08 UTC | added derived Reshape() variants ReshapeDimension(), FlattenDimensions(), and SplitDimension to BrainScript; undid accidental commit of a config file modified for a debug test | 06 January 2016, 03:42:08 UTC |
| e7c9ae7 | Frank Seide | 06 January 2016, 03:21:03 UTC | implemented new ReshapeNode (which works with arbitrary tensor dims, but cannot swap dimensions into time--use TransposeNode for that in the future); old ReshapeNode renamed to DeprecatedReshapeNode. Still available from BrainScript for now, while new implementation is invoked as NewReshape(). This will change soon; bug fix: a few Validate() functions did not check isFinalValidationPass and failed on temporary input; bug fix: upwards-compatible Save/Load in convolution nodes by spltting one size_t into two uint32_t got the order wrong; bug fix: convolution nodes should only create convolution engines in final validation | 06 January 2016, 03:21:03 UTC |

| cae4c56 | Frank Seide | 05 January 2016, 22:19:16 UTC | added a new name "ImageParameter" for LearnableParameter that expects 3 input dimensions which are interpreted as WHC and mapped to actual tensor dimensions according to the optional imageLayout parameter. Adapted the NDL of the Image/QuickE2E test | 05 January 2016, 22:19:16 UTC |
| 97e0459 | bmitra | 05 January 2016, 20:50:35 UTC | Add missing definition to NoGPU.cpp. | 05 January 2016, 20:50:35 UTC |
| d013344 | Frank Seide | 05 January 2016, 20:11:27 UTC | Past/FutureValue now takes a dimension tensor in BrainScript; removed cols/numImages parameter from InputValue and Past/FutureValue, since those always process data samples. Lots of little deletions in SimpleNetworkBuilder.cpp | 05 January 2016, 20:11:27 UTC |
| 84c50f7 | Amit | 05 January 2016, 19:15:58 UTC | Fix CPUONLY build | 05 January 2016, 19:15:58 UTC |

| cfd4a8e | Frank Seide | 02 January 2016, 04:38:31 UTC | Coup de grâce: the 3 basic elementwise arithmetic operation (plus, minus, element times) and the 6 main non-linearity nodes (all except softmax and GMM) have been replaced by the new tensor library. This makes the code significantly more compact and allows broadcasting along any dimension, e.g. for implementing the image bias | 02 January 2016, 04:38:31 UTC |
| 2d8b9e7 | Frank Seide | 02 January 2016, 03:20:35 UTC | bug fix in ConvolutionEngineTests.cpp: when testing CPU, use HWC layout | 02 January 2016, 03:20:35 UTC |

| b5a5c86 | Frank Seide | 02 January 2016, 00:47:20 UTC | made gcc happy | 02 January 2016, 00:47:20 UTC |
| e09548f | Frank Seide | 02 January 2016, 00:38:20 UTC | replaced 6 non-linearity nodes by a single base class and 6 macros, as those 6 nodes were now structurally identical and only differed in TensorView opcodes | 02 January 2016, 00:38:20 UTC |
| 351358e | Frank Seide | 02 January 2016, 00:14:01 UTC | implemented most non-linearity nodes using the tensor lib | 02 January 2016, 00:14:01 UTC |
| 5ff5d68 | Frank Seide | 01 January 2016, 23:05:19 UTC | added imageLayout parameter to Convolution, MaxPooling, and AveragePooling (only Convolution had it, and BrainScrip only); bug fix: LearnableParameter must also serialize m_sampleLayout | 01 January 2016, 23:05:19 UTC |
| 50218cd | Frank Seide | 01 January 2016, 21:18:49 UTC | Image/QuickE2E now implements both legacy and cudnn layouts, selected by a command-line overridable parameter 'useCuDnn' that defaults to cudnn; added printfs to cunn tests | 01 January 2016, 21:18:49 UTC |
| ec29314 | Frank Seide | 01 January 2016, 21:04:59 UTC | move ScaleNode, RowElementTimesNode, and ColumnElementTimesNode to EsotericNodes.h, to indicate that they are deprecated (which they will be once tensor lib is enabled generally); changed Image/QuickE2E test to use cudnn | 01 January 2016, 21:04:59 UTC |
| 1506c67 | Frank Seide | 01 January 2016, 20:45:08 UTC | made gcc happy; changed ConvolutionEngineTests.cpp to use CHW layout since it only runs with cuDNN | 01 January 2016, 20:45:08 UTC |
| 0c79c92 | Frank Seide | 01 January 2016, 20:25:24 UTC | cleanedup ConvolutionNode vs. image interpretation of TensorShape; TensorOp() optimization to use SGEMM disabled for 'double' in Debug builds, so we get our code path tested once in a while; fixed ConvolutionEngineTests.cpp w.r.t. Create(); removed unused InputIsImage() methods | 01 January 2016, 20:25:24 UTC |

| 42ff20b | Frank Seide | 31 December 2015, 05:20:11 UTC | (comment) | 31 December 2015, 05:20:11 UTC |
| 9db7cce | Frank Seide | 31 December 2015, 05:19:03 UTC | towards passing the ImageLayoutKind into ConvolutionNode and friends; ConvolutionEngineFactory::Create() now chooses the layout based on the user-specified ImageLayoutKind. Something is borked, this version mixes up dimensions somewhere | 31 December 2015, 05:19:03 UTC |
| d11532c | Frank Seide | 31 December 2015, 03:55:06 UTC | (deleted some obsolete debug code) | 31 December 2015, 03:55:06 UTC |
| 9372b6a | Frank Seide | 31 December 2015, 03:51:28 UTC | bug fix: SetMaxTempMemSizeForCNN() was missing the 'double' case; added an optimization to unary TensorOp() to use cublasS/Dgemm() when we are reducing a matrix | 31 December 2015, 03:51:28 UTC |
| 329c77c | Frank Seide | 31 December 2015, 00:55:27 UTC | switched ReduceElemType to ElemType instead of double while reenabling PlusNode TensorView--desparate to get Image/QuickE2E to pass | 31 December 2015, 00:55:27 UTC |
| 9003f4c | Frank Seide | 31 December 2015, 00:40:49 UTC | disabled TensorView for PlusNode::BackpropTo(), as that causes a difference for Image/QuickE2E; GetTensorShape() now adds the column dimension as one more dimension | 31 December 2015, 00:40:49 UTC |
| 411e21f | Frank Seide | 31 December 2015, 00:00:02 UTC | switched inaccurate Sigmoid() and PlusNode::BackpropTo() back on; changed Image/QuickE2E to use BrainScript, in order to allow specifiyng tensor dimensions for the bias | 31 December 2015, 00:00:02 UTC |
| ac61d22 | Frank Seide | 30 December 2015, 22:51:52 UTC | switched to new Sigmoid(), PlusNode::BackpropTo() still not TensorView | 30 December 2015, 22:51:52 UTC |
| 6da94eb | Frank Seide | 30 December 2015, 22:40:53 UTC | re-disabled PlusNode::BackpropTo() once again | 30 December 2015, 22:40:53 UTC |
| ec4c08d | Frank Seide | 30 December 2015, 22:31:35 UTC | reenabled ENABLE_BROADCASTING_ELEMENTTIMES | 30 December 2015, 22:31:35 UTC |
| 50159b7 | Frank Seide | 30 December 2015, 22:30:30 UTC | switched TensorOp.h's Sigmoid() to the less accurate version from the .cuh file, to remove failure in SequenceTraining test. This is not good! Reenabled all TensorView | 30 December 2015, 22:30:30 UTC |
| 3f5e5b9 | Frank Seide | 30 December 2015, 22:15:00 UTC | disabled TensorView for PlusNode::BackpropTo() and SigmoidNode, now gives the same for Image/QuickE2E | 30 December 2015, 22:15:00 UTC |
| 710e2b5 | Frank Seide | 30 December 2015, 20:50:13 UTC | InputValue and LearnableParameter C++ objects now take their dimensions as a general tensor (but not yet on BS level); InputValue no longer accepts a column argument (ignored in NDL, forbidden in BS); bug fix in ConfigArray::AsVector() | 30 December 2015, 20:50:13 UTC |
| c6d908e | Frank Seide | 30 December 2015, 19:35:40 UTC | new optional NDL/BS parameter 'imageLayout' to say according to which of the two layouts (cudnn or CNTL legacy) we should interpret a W, H, C specification. Currently implemented for InputImage; InputValue no longer accepts a 'cols' parameter. Instead, it ignores it and uses 0 instead, since InputValues must always be minibatches | 30 December 2015, 19:35:40 UTC |
| d0b5c8d | Frank Seide | 30 December 2015, 18:57:08 UTC | bug fix: CeilDiv() overflowed for b == INT_MAX | 30 December 2015, 18:57:08 UTC |

| 44c1e54 | Frank Seide | 30 December 2015, 17:11:02 UTC | merged GPUMatrixCUDAKernels.cuh DEF_ELEMENT_PRIMITIVE macro with TensorOps.h OverloadUnaryMathFns, as both did the same thing; new #define ENABLE_BROADCASTING_ELEMENTTIMES to specifically select whether we want to replace ScaleNode etc with ElementTimesNode | 30 December 2015, 17:11:02 UTC |
| cd86e1f | Frank Seide | 30 December 2015, 06:11:57 UTC | (comments) | 30 December 2015, 06:11:57 UTC |

| ed35440 | Frank Seide | 30 December 2015, 05:29:17 UTC | added new tensor operations: And, Or, Xor, ElementwiseProductWithSigmoidDerivative (SigmoidDerivative is only ever used in this context), and Clip | 30 December 2015, 05:29:17 UTC |
| c4356c1 | Frank Seide | 30 December 2015, 04:50:54 UTC | reenabled all existing uses of TensorView; ScaleNode and Row/ColumnElementTimesNode now implemented as ElementTimesNode | 30 December 2015, 04:50:54 UTC |
