//
//c.RootUrl(req => GetRootUrlFromAppConfig());
// If schemes are not explicitly provided in a Swagger 2.0 document, then the scheme used to access
// the docs is taken as the default. If your API supports multiple schemes and you want to be explicit
// about them, you can use the "Schemes" option as shown below.
//
//c.Schemes(new[] { "http", "https" });
// Use "SingleApiVersion" to describe a single version API. Swagger 2.0 includes an "Info" object to
// hold additional metadata for an API. Version and title are required but you can also provide
// additional fields by chaining methods off SingleApiVersion.
//
c.SingleApiVersion("v1", "CNTKAzureTutorial01");
// If your API has multiple versions, use "MultipleApiVersions" instead of "SingleApiVersion".
// In this case, you must provide a lambda that tells Swashbuckle which actions should be
// included in the docs for a given API version. Like "SingleApiVersion", each call to "Version"
// returns an "Info" builder so you can provide additional metadata per API version.

//c.MultipleApiVersions(

// You can use "BasicAuth", "ApiKey" or "OAuth2" options to describe security schemes for the API.
// See https://github.com/swagger-api/swagger-spec/blob/master/versions/2.0.md for more details.
// NOTE: These only define the schemes and need to be coupled with a corresponding "security" property
// at the document or operation level to indicate which schemes are required for an operation. To do this,
// you'll need to implement a custom IDocumentFilter and/or IOperationFilter to set these properties
// according to your specific authorization implementation

//c.IgnoreObsoleteActions();
// Each operation be assigned one or more tags which are then used by consumers for various reasons.
// For example, the swagger-ui groups operations according to the first tag of each operation.
// By default, this will be controller name but you can use the "GroupActionsBy" option to
// override with any value.
//
//c.GroupActionsBy(apiDesc => apiDesc.HttpMethod.ToString());
// You can also specify a custom sort order for groups (as defined by "GroupActionsBy") to dictate
// the order in which operations are listed. For example, if the default grouping is in place
// (controller name) and you specify a descending alphabetic sort order, then actions from a
// ProductsController will be listed before those from a CustomersController. This is typically
// used to customize the order of groupings in the swagger-ui.
//
//c.OrderActionGroupsBy(new DescendingAlphabeticComparer());
// If you annotate Controllers and API Types with
// Xml comments (http://msdn.microsoft.com/en-us/library/b2s063f7(v=vs.110).aspx), you can incorporate
// those comments into the generated docs and UI. You can enable this by providing the path to one or
// more Xml comment files.
//
//c.IncludeXmlComments(GetXmlCommentsPath());
// Swashbuckle makes a best attempt at generating Swagger compliant JSON schemas for the various types
// exposed in your API. However, there may be occasions when more control of the output is needed.
// This is supported through the "MapType" and "SchemaFilter" options:
//
// Use the "MapType" option to override the Schema generation for a specific type.
// It should be noted that the resulting Schema will be placed "inline" for any applicable Operations.
// While Swagger 2.0 supports inline definitions for "all" Schema types, the swagger-ui tool does not.
// It expects "complex" Schemas to be defined separately and referenced. For this reason, you should only
// use the "MapType" option when the resulting Schema is a primitive or array type. If you need to alter a
// complex Schema, use a Schema filter.
//
//c.MapType<ProductType>(() => new Schema { type = "integer", format = "int32" });
// If you want to post-modify "complex" Schemas once they've been generated, across the board or for a
// specific type, you can wire up one or more Schema filters.
//
//c.SchemaFilter<ApplySchemaVendorExtensions>();
// In a Swagger 2.0 document, complex types are typically declared globally and referenced by unique
// Schema Id. By default, Swashbuckle does NOT use the full type name in Schema Ids. In most cases, this
// works well because it prevents the "implementation detail" of type namespaces from leaking into your
// Swagger docs and UI. However, if you have multiple types in your API with the same class name, you'll
// need to opt out of this behavior to avoid Schema Id conflicts.
//
//c.UseFullTypeNameInSchemaIds();
// Alternatively, you can provide your own custom strategy for inferring SchemaId's for
// describing "complex" types in your API.
//
//c.SchemaId(t => t.FullName.Contains('`') ? t.FullName.Substring(0, t.FullName.IndexOf('`')) : t.FullName);
// Set this flag to omit schema property descriptions for any type properties decorated with the
// Obsolete attribute
//c.IgnoreObsoleteProperties();
// In accordance with the built in JsonSerializer, Swashbuckle will, by default, describe enums as integers.
// You can change the serializer behavior by configuring the StringToEnumConverter globally or for a given
// enum type. Swashbuckle will honor this change out-of-the-box. However, if you use a different
// approach to serialize enums as strings, you can also force Swashbuckle to describe them as strings.
//
//c.DescribeAllEnumsAsStrings();
// Similar to Schema filters, Swashbuckle also supports Operation and Document filters:
//
// Post-modify Operation descriptions once they've been generated by wiring up one or more
// Operation filters.
//
//c.OperationFilter<AddDefaultResponse>();
//
// If you've defined an OAuth2 flow as described above, you could use a custom filter
// to inspect some attribute on each action and infer which (if any) OAuth2 scopes are required
// to execute the operation
//
//c.OperationFilter<AssignOAuth2SecurityRequirements>();
//
// Set filter to eliminate duplicate operation ids from being generated
// when there are multiple operations with the same verb in the API.
// ***
// If you would prefer to globally impact the Swagger operation id's rather
// than control them on a per-action method basis, uncomment the next line
// and the IncludeParameterNamesInOperationIdFilter class below.
// ***
//c.OperationFilter<IncludeParameterNamesInOperationIdFilter>();
//
// Post-modify the entire Swagger document by wiring up one or more Document filters.
// This gives full control to modify the final SwaggerDocument. You should have a good understanding of
// the Swagger 2.0 spec. - https://github.com/swagger-api/swagger-spec/blob/master/versions/2.0.md
// before using this option.
//
//c.DocumentFilter<ApplyDocumentVendorExtensions>();
// In contrast to WebApi, Swagger 2.0 does not include the query string component when mapping a URL
// to an action. As a result, Swashbuckle will raise an exception if it encounters multiple actions
// with the same path (sans query string) and HTTP method. You can workaround this by providing a
// custom strategy to pick a winner or merge the descriptions for the purposes of the Swagger docs
//
//c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
// Wrap the default SwaggerGenerator with additional behavior (e.g. caching) or provide an
// alternative implementation for ISwaggerProvider with the CustomProvider option.
//
//c.CustomProvider((defaultProvider) => new CachingSwaggerProvider(defaultProvider));
// ***** Uncomment the following to enable the swagger UI *****

// Use the "InjectStylesheet" option to enrich the UI with one or more additional CSS stylesheets.
// The file must be included in your project as an "Embedded Resource", and then the resource's

//
//c.InjectStylesheet(containingAssembly, "Swashbuckle.Dummy.SwaggerExtensions.testStyles1.css");
// Use the "InjectJavaScript" option to invoke one or more custom JavaScripts after the swagger-ui

// "Logical Name" is passed to the method as shown above.
//
//c.InjectJavaScript(thisAssembly, "Swashbuckle.Dummy.SwaggerExtensions.testScript1.js");
// The swagger-ui renders boolean data types as a dropdown. By default, it provides "true" and "false"
// strings as the possible choices. You can use this option to change these to something else,
// for example 0 and 1.
//
//c.BooleanValues(new[] { "0", "1" });
// By default, swagger-ui will validate specs against swagger.io's online validator and display the result
// in a badge at the bottom of the page. Use these options to set a different validator URL or to disable the
// feature entirely.
//c.SetValidatorUrl("http://localhost/validator");
//c.DisableValidator();
// Use this option to control how the Operation listing is displayed.
// It can be set to "None" (default), "List" (shows operations for each resource),
// or "Full" (fully expanded: shows operations and their details).
//
//c.DocExpansion(DocExpansion.List);
// Use the CustomAsset option to provide your own version of assets used in the swagger-ui.
// It's typically used to instruct Swashbuckle to return your version instead of the default
// when a request is made for "index.html". As with all custom content, the file must be included
// in your project as an "Embedded Resource", and then the resource's "Logical Name" is passed to
// the method as shown below.

#EvalClients
The folder contains some examples using the CNTK evaluation library. Please note that only the 64-bit target is supported by CNTK evaluation library.
-CPPEvalClient: demonstrate the use of the C++ CNTK eval lib. Only the release configuration is supported.
-CSEvalClient: demonstrate the use of the C# CNTK eval lib.
-EvalClients.sln: the VS2013 solution file to build examples. It creates two binaries in the directory $(SolutionDir)..\..\x64\:
* CPPEvalClient.$(Configuration)\CPPEvalClient.exe: the C++ example executable. To run the example, please first include the directory containing CNTK dependent dlls, usually $(SolutionDir)..\..\cntk, in the PATH environment variable.
* CSEvalClient.$(Configuration)\CSEvalClient.exe: the C# example executable.

`cntk configFile=Config/01_OneHidden_ndl_deprecated.cntk currentDirectory=Data`
The output folder will be created inside Image/MNIST/.
@ -61,22 +61,22 @@ There are four config files and the corresponding network description files in t
1. 01_OneHidden.ndl is a simple, one hidden layer network that produces 2.3% of error.
To run the sample, navigate to the Data folder and run the following command:
`cntk configFile=../Config/01_OneHidden.cntk`
`cntk configFile=../Config/01_OneHidden_ndl_deprecated.cntk`
2. 02_Convolution.ndl is more interesting, convolutional network which has 2 convolutional and 2 max pooling layers.
The network produces 0.87% of error after training for about 2 minutes on GPU.
To run the sample, navigate to the Data folder and run the following command:
`cntk configFile=../Config/02_Convolution.cntk`
`cntk configFile=../Config/02_Convolution_ndl_deprecated.cntk`
3. 03_ConvBatchNorm.ndl is almost identical to 02_Convolution.ndl
except that it uses batch normalization for the convolutional and fully connected layers.
As a result, it achieves around 0.8% of error after training for just 2 epochs (and less than 30 seconds).
To run the sample, navigate to the Data folder and run the following command:
`cntk configFile=../Config/03_ConvBatchNorm.cntk`
`cntk configFile=../Config/03_ConvBatchNorm_ndl_deprecated.cntk`
4. 04_DeConv.ndl illustrates the usage of Deconvolution and Unpooling. It is a network with one Convolution, one Pooling, one Unpooling and one Deconvolution layer. In fact it is an auto-encoder network where Rectified Linear Unit (ReLU) or Sigmoid layer is now replaced with Convolutional ReLU (for encoding) and Deconvolutional ReLU (for decoding) layers. The network goal is to reconstruct the original signal, with Mean Squared Error (MSE) used to minimize the reconstruction error. Generally such networks are used in semantic segmentation.
To run the sample, navigate to the Data folder and run the following command:
`cntk configFile=../Config/04_DeConv.cntk`
`cntk configFile=../Config/04_DeConv_ndl_deprecated.cntk`
For more details, refer to .ndl and the corresponding .cntk files.

### Getting the data

CIFAR-10 dataset is not included in CNTK distribution but can be easily downloaded and converted by running the following commands from this folder:
`python CIFAR_convert.py [-f <format: cudnn|legacy>]`
The script will download all required files and convert them to CNTK-supported format.
In case you don't have a Python installed, there are 2 options:
1. Download and install latest version of Python 2.7 from: https://www.python.org/downloads/
Then install numpy package by following instruction from: http://www.scipy.org/install.html#individual-packages
2. Alternatively install Python Anaconda distribution which contains most of the popular Python packages including numpy:
http://continuum.io/downloads
`-f` parameter is optional and specifies output format of the datasets. `cudnn` option (default) saves dataset in a spatial-major format used by cuDNN, while `legacy` - in CNTK legacy format. Use `cudnn` if CNTK is compiled with cuDNN and `legacy` otherwise.
ResNet samples require converting CIFAR-10 dataset to actual images. This can be performed by running the following command:
```
python CifarDownload.py [-f <format: cudnn|legacy>]
python CifarConverter.py <path to CIFAR-10 dataset>
```
The script takes a full path to the original CIFAR-10 dataset (in Python pickle format). The script will create `data` folder inside of provided path where it will store both train and test images (in `train` and `test` folders). It will also create appropriate mapping files for the CNTK ImageReader as well as mean file.
The scripts will download all required files and convert them to CNTK-supported format.

The network produces 20.5% of error after training for about 3 minutes on GPU.
To run the sample, navigate to the sample folder and run the following command:
```
cntk configFile=01_Conv.cntk
cntk configFile=01_Conv_ndl_deprecated.cntk
```
2. 02_BatchNormConv.ndl is a convolutional network which uses batch normalization technique (http://arxiv.org/abs/1502.03167).
To run the sample, navigate to the sample folder and run the following command:
```
cntk configFile=02_BatchNormConv.cntk
cntk configFile=02_BatchNormConv_ndl_deprecated.cntk
```
3. 03_ResNet.ndl and 04_ResNet_56.ndl are very deep convolutional networks that use ResNet architecture and have 20 and 56 layers respectively (http://arxiv.org/abs/1512.03385).
With 03_ResNet.cntk you should get around 8.2% of error after training for about 50 minutes. 04_ResNet_56.cntk should produce around 6.4% of error after training for about 3 hours (see log files in the Output directory).

4. 05_ConvLocal.cntk uses locally-connected convolution layers (see `conv_local3` and `conv_local4` in `05_ConvLocal.cntk`) and resembles a network described here: https://code.google.com/p/cuda-convnet/source/browse/trunk/example-layers/layers-conv-local-11pct.cfg

5. 06_RegressionSimple.cntk shows how to train a regression model on image data. It uses a very simple network and a composite reader using both the ImageReader and CNTKTextFormatReader and defines a the RMSE (root mean square error) as the loss function. The value that the network learns to predict are simply the average rgb values of an image normalized to [0, 1]. To generate the ground truth labels for regression you need to run the CifarConverter.py script (since this example was added later you might need to rerun it to generate the regression files). See also here: https://github.com/Microsoft/CNTK/wiki/Train-a-regression-model-on-images
For more details, refer to .ndl and corresponding .cntk files.

# CNTK
## Latest news
*2016-08-10.* CNTK now supports **Gated Recurrent Units (GRU)**. Read more in the [corresponding article](https://github.com/Microsoft/CNTK/wiki/GRUs-on-CNTK-with-BrainScript).
*2016-08-31.* V 1.7 Binary release
Highlights of this Release:
* Improvements in BrainScript (New library of predefined common layer types, Support of cuDNN5 RNN and Common random-initialization types, improved handling of GRUs)
* Support of NVIDIA cuDNN 5.1
* Improvements in Readers and Deserializers
* Additions to Evaluator Library (Eval Client Sample, Strong Name for EvalWrapper)
* New in Unit Tests (Linux support, Randomization engines)
* Python API Preview (since V.1.5)
* Multiple bug fixes
See more in the [Release Notes](https://github.com/Microsoft/CNTK/wiki/CNTK_1_7_Release_Notes)
Get the Release from the [CNTK Releases page](https://github.com/Microsoft/CNTK/releases)
*2016-08-29.* Two new Tutorials are available:
[Image recognition](https://github.com/Microsoft/CNTK/wiki/Hands-On-Labs-Image-Recognition) (CIFAR-10) and [Language understanding](https://github.com/Microsoft/CNTK/wiki/Hands-On-Labs-Image-Recognition) (ATIS).
*2016-08-10.* We have significantly simplified handling of **Gated Recurrent Units (GRU)**. Read more in the [corresponding article](https://github.com/Microsoft/CNTK/wiki/GRUs-on-CNTK-with-BrainScript).
*2016-07-15.* V 1.6 Binary release
CNTK v.1.6 binaries are on the [CNTK Releases page](https://github.com/Microsoft/CNTK/releases)
*2016-07-12.* We have further expanded Licensing options for CNTK 1bit-SGD and related components. See the details at the [Wiki page](https://github.com/microsoft/cntk/wiki/CNTK-1bit-SGD-License). These new options are an extension of the new CNTK 1bit-SGD License that we have announced on Jun 23, 2016.
*2016-07-05.* CNTK now supports *Deconvolution* and *Unpooling*. See the usage example in the Network number 4 in [MNIST Sample](https://github.com/Microsoft/CNTK/blob/master/Examples/Image/MNIST/README.md).
*2016-06-23.* New License Terms for CNTK 1bit-SGD and related components.
Effective immediately the License Terms for CNTK 1bit-SGD and related components have changed. The new Terms provide more flexibility and enable new usage scenarios, especially in commercial environments. Read the new Terms at the [standard location](https://cntk1bitsgd.codeplex.com/license). Please note, that while the new Terms are significantly more flexible comparing to the previous ones, they are still **more restrictive** than the main CNTK License. Consequently everything described in [Enabling 1bit-SGD](https://github.com/Microsoft/CNTK/wiki/Enabling-1bit-SGD) section of the Wiki remains valid.
See [all news](https://github.com/Microsoft/CNTK/wiki/News).
