Merge pull request #1977 from shelhamer/accum-grad Decouple the computational batch size and minibatch size by accumulating gradients

Merge pull request #2410 from sguada/datum_transform Datum transform

2015-05-27

zero-init param diffs and accumulate gradients (With layers whose backward accumulates gradients), this effectively decouples the computational batch from the SGD minibatch. Each iteration accumulates gradients over iter_size batches, then parameters are updated.

Merge pull request #1946 from nickcarlevaris/msra_init Add MSRAFiller, an Xavier-like filler designed for use with ReLUs

Added MSRAFiller, an Xavier-like filler designed for use with ReLUs ...instead of tanh. Based on paper: He et al, "Delving Deep into Rectifiers: Surpassing Human-Level Performance on ImageNet Classification," 2015. - add VarianceNorm option to FillerParameters which allows one to normalize by fan_in, fan_out or their average. - update XavierFiller to use the VarianceNorm option (default behavior unchanged). - add tests for MSRAFiller and XavierFiller.

shuffle data

2015-03-12

PReLU Layer and its tests described in Kaiming He et al, "Delving Deep into Rectifiers: Surpassing Human-Level Performance on ImageNet Classification", arxiv 2015. Belows are commit message histories that I had while developing. PReLULayer takes FillerParameter for init PReLU testing consistency with ReLU Fix : PReLU test concistency check PReLU tests in-place computation, and it failed in GPU Fix: PReLU in-place backward in GPU PReLULayer called an incorrect API for copying data (caffe_gpu_memcpy). First argment of `caffe_gpu_memcpy` should be size of memory region in byte. I modified to use `caffe_copy` function. Fix: style errors Fix: number of axes of input blob must be >= 2 Use 1D blob, zero-D blob. Rename: hw -> dim

2015-03-09

AccuracyLayer: add ignore_label param

Fixup AccuracyLayer like SoftmaxLossLayer in #1970 -- fixes #2063

2015-03-03

DummyDataLayer outputs blobs of arbitrary shape

SliceLayer: generalized Blob axes

SoftmaxLayer: generalized Blob axes

ConcatLayer: generalized Blob axes

InnerProductLayer can multiply along any axis

Blobs are ND arrays (for N not necessarily equals 4). vector<int> shape_ instead of (num, channels, height, width).

Add BlobShape message; use for Net input shapes

2015-02-20

Merge pull request #1910 from philkr/encoded add force_encoded_color flag to the data layer and warn about mixed encoding

added a force_encoded_color flag to the data layer. Printing a warning if images of different channel dimensions are encoded together

2015-02-17

give phase to Net and Layer Give the responsibility for phase to Net and Layer, making phase an immutable choice at instantiation and dropping it from the Caffe singleton.

[pycaffe] allow Layer to be extended from Python This is done by adding PythonLayer as a boost::python HeldType.

2015-02-14

Add gradient clipping -- limit L2 norm of parameter gradients

2015-02-06

fix for layer-type-str: loss_param and DECONVOLUTION type should have been included in V1LayerParameter, get upgraded

2015-02-05

start layer parameter field IDs at 100 (always want them printed at the end, and want to allow more fields to be added in the future, so reserve fields 10-99 for that purpose)

automagic upgrade for v1->v2

'layers' -> 'layer'

restore upgrade_proto

add message ParamSpec to replace param name, blobs_lr, weight_decay, ...

get rid of NetParameterPrettyPrint as layer is now after inputs (whoohoo)

Layer type is a string

add DeconvolutionLayer, using BaseConvolutionLayer

2014-12-31

add spatial normalization option to SoftmaxLossLayer With missing values (and batches of varying spatial dimension), normalizing each batch across instances can inappropriately give different instances different weights, so we give the option of simply normalizing by the batch size instead.
