+<p>To train a model in SINGA, you need to prepare the datasets, and a job configuration which specifies the neural net structure, training algorithm (BP or CD), SGD update algorithm (e.g. Adagrad), number of training/test steps, etc.</p>
+<div class="section">
+<h3><a name="Data_preparation"></a>Data preparation</h3>
+<p>Before using SINGA, you need to write a program to convert the dataset into a format that SINGA can read. Please refer to the <a href="data.html#example---cifar-dataset">Data Preparation</a> to get details about preparing this CIFAR10 dataset.</p></div>

Sometimes the rectifier layer and normalization layer are omitted or swapped in one stage. For this example, there are 3 such stages.</p>

+            <h1>Data Preparation</h1>
+<hr />
+<p>SINGA uses input layers to load data. Users can store their data in any format (e.g., CSV or binary) and at any places (e.g., disk file or HDFS) as long as there are corresponding input layers that can read the data records and parse them.</p>
+<p>To make it easy for users, SINGA provides a [StoreInputLayer] to read data in the format of (string:key, string:value) tuples from a couple of sources. These sources are abstracted using a <a href="">Store</a> class which is a simple version of the DB abstraction in Caffe. The base Store class provides the following operations for reading and writing tuples,</p>
+
+<div class="source">
+<div class="source"><pre class="prettyprint">Open(string path, Mode mode); // open the store for kRead or kCreate or kAppend
+Close();
+
+Read(string* key, string* val); // read a tuple; return false if fail
+Write(string key, string val);  // write a tuple
+Flush();
+</pre></div></div>
+<p>Currently, two implementations are provided, namely</p>
+
+<ol style="list-style-type: decimal">
+  
+<li>
+<p>[KVFileStore] for storing tuples in <a href="">KVFile</a> (a binary file). The <i>create_data.cc</i> files in <i>examples/cifar10</i> and <i>examples/mnist</i> provide examples of storing records using KVFileStore.</p></li>
+  
+<li>
+<p>[TextFileStore] for storing tuples in plain text file (one line per tuple).</p></li>
+</ol>
+<p>The (key, value) tuple are parsed by subclasses of StoreInputLayer depending on the format of the tuple,</p>
+
+<ul>
+  
+<li>
+<p>[ProtoRecordInputLayer] parses the value field from one tuple into a [SingleLabelImageRecord], which is generated by Google Protobuf according to [common.proto]. It can be used to store features for images (e.g., using the pixel field) or other objects (using the data field). The key field is not used.</p></li>
+  
+<li>
+<p>[CSVRecordInputLayer] parses one tuple as a CSV line (separated by comma).</p></li>
+</ul>
+<div class="section">
+<h2><a name="Using_built-in_record_format"></a>Using built-in record format</h2>
+<p>SingleLabelImageRecord is a built-in record in SINGA for storing image features. It is used in the cifar10 and mnist examples.</p>
+
+<div class="source">
+<div class="source"><pre class="prettyprint">message SingleLabelImageRecord {
+  repeated int32 shape = 1;                // it obtains 3 (rgb channels), 32 (row), 32 (col)
+  optional int32 label = 2;                // label
+  optional bytes pixel = 3;                // pixels
+  repeated float data = 4 [packed = true]; // it is used for normalization
+</pre></div></div>
+<p>}</p>
+<p>The data preparation instructions for the <a class="externalLink" href="http://www.cs.toronto.edu/~kriz/cifar.html">CIFAR-10 image dataset</a> will be elaborated here. This dataset consists of 60,000 32x32 color images in 10 classes, with 6,000 images per class. There are 50,000 training images and 10,000 test images. Each image has a single label. This dataset is stored in binary files with specific format. SINGA comes with the <a class="externalLink" href="https://github.com/apache/incubator-singa/blob/master/examples/cifar10/create_data.cc">create_data.cc</a> to convert images in the binary files into <tt>SingleLabelImageRecord</tt>s and insert them into training and test stores.</p>
+
+<ol style="list-style-type: decimal">
+  
+<li>
+<p>Download raw data. The following command will download the dataset into <i>cifar-10-batches-bin</i> folder.</p>
+  
+<div class="source">
+<div class="source"><pre class="prettyprint"># in SINGA_ROOT/examples/cifar10
+$ cp Makefile.example Makefile   // an example makefile is provided
+$ make download
+</pre></div></div></li>
+  
+<li>
+<p>Fill one record for each image, and insert it to store.</p>
+  
+<div class="source">
+<div class="source"><pre class="prettyprint">KVFileStore store;
+store.Open(output_file_path, singa::io::kCreate);
+
+singa::SingleLabelImageRecord image;
+for (int image_id = 0; image_id &lt; 50000; image_id ++) {
+  // fill the record with image feature and label from downloaded binay files
+  string str;
+  image.SerializeToString(&amp;str);
+  store.Write(to_string(image_id), str);
+}
+store.Flush();
+store.Close();
+</pre></div></div>
+<p>The data store for testing data is created similarly. In addition, it computes average values (not shown here) of image pixels and insert the mean values into a SingleLabelImageRecord, which is then written into a another store.</p></li>
+  
+<li>
+<p>Compile and run the program. SINGA provides an example Makefile that contains instructions for compiling the source code and linking it with <i>libsinga.so</i>. Users just execute the following command.</p>
+  
+<div class="source">
+<div class="source"><pre class="prettyprint">$ make create
+</pre></div></div></li>
+</ol></div>
+<div class="section">
+<h2><a name="using_user-defined_record_format"></a>using user-defined record format</h2>
+<p>If users cannot use the SingleLabelImageRecord or CSV record for their data. They can define their own record format e.g., using Google Protobuf. A record can be written into a data store as long as it can be converted into byte string. Correspondingly, subclasses of StoreInputLayer are required to parse user-defined records.</p></div>

+<hr />
+<p>SINGA is designed for distributed training of large deep learning models with huge amount of training data. We also provide high-level descriptions of design behind SINGA&#x2019;s distributed architecture. </p>

+  
+<li>
+<p><a href="communication.html">System Communication</a></p></li>
+</ul>
+<p>SINGA supports different options for training a model in parallel, includeing data parallelism, model parallelism and hybrid parallelism.</p>
+
+<ul>
+  
+<li><a href="hybrid.html">Hybrid Parallelism</a></li>
+</ul>
+<p>SINGA is intergrated with Mesos, so that distributed training can be started as a Mesos framework. Currently, the Mesos cluster can be set up from SINGA containers, i.e. we provide Docker images that bundles Mesos and SINGA together. Refer to the guide below for instructions as how to start and use the cluster.</p>

+<li><a href="mesos.html">Distributed training on Mesos</a></li>
+</ul>
+<p>SINGA can run on top of distributed storage system to achieve scalability. The current version of SINGA supports HDFS.</p>
