 Step-by-step Deep Leaning Tutorials on Apache Spark using [BigDL](https://github.com/intel-analytics/BigDL/). The tutorials are inspired by [Apache Spark examples](http://spark.apache.org/examples.html), the [Theano Tutorials](https://github.com/Newmu/Theano-Tutorials) and the [Tensorflow tutorials](https://github.com/nlintz/TensorFlow-Tutorials).
 
+- Preface
+  - prologgue
+  - Organization of the tutorials
+  - advices and prerequisites for learners
+ 
+ - Introduction to Spark basics(topic 1-4)
+   - introduction to What Spark is, current usage and application(provided by useful links from Spark official site)
+   - environment setting and install instructions
+   - RDD
+   - DataFrame
+   - SparkSAL
+   - Structured Streaming
+ 
+ - Supervised Learning with BigDL(topic 6-8)
+   - install dependencies and set up the envrionment(imports)
+   - Introduction to Supervised Learning
+     - Linear Regression with BigDL(topic 6)
+       - About batch training
+       - Data Generation
+       - Hyperperameter setup
+       - model creation with Linear layer
+       - Loss function
+       - Optimizer
+       - Execute Training
+       - Prediction on training data
+       - Model evaluation on random test data
+     
+     - Binary classification with logistic regression
+       - similar to structure in "Linear Regression with BigDL" but we bring the introduction to 
+         "BigDL's train_summary and validation summary API" and "how to use them to visualize the learing curve" here
+     
+     - Multiclass classification with logistic regression(topic 8)
+       - introduction to MNIST dataset (topic 7)
+       - rest is same to the structure in "Linear Regression with BigDL"
+     
+     - Overfitting and Regularization with BigDL
+       - What is overfitting with example
+       - Use regulariztion to solve overfitting
+       - regularization in BigDL
+  
+  
+ - Nerual Networks with BigDL
+   - Introduction to neural networks
+   - install dependencies and imports
+   - mechanics of weight and gradient update
+     - Forward and backward(topic 5)
+   - Feedforward Neural Network(topic 9)
+   - RNN(topic 11)
+   - Bi-RNN(topic 13)
+   - LSTM(topic 12)
+   - CNN(topic 10 will include "batch normalization" here)
+     - batch normalization
+   - Auto-encoder(topic 14)
+       
+    *These neural network topics will have the same structure in "Binary classification with logistic regression"*
