Stream Data Mining • Challenge
Velocity is most salient property of
telecommunication data
Example: data in datacenter flows
in several TBs per second
To predict data flow in SDN
• Solution
• Stream Data Platform: StreamSmart
• Processing one million events in one second on single machine
• Twice as fast as Storm
• Technology
• Auto load balancing
• Distributed auto recovery
• Shared ring buffer
• Light-weight distributed computation

Graph Data Mining
• Challenge • Graph data is everywhere
• Scale is large
• Predict data flow in of network
• Solution
• Graph data mining platform:
VENUS
• PageRank on Twitter graph,
almost one times faster than
GraphChi on single machine
• Vertex-centric streamlined
processing

Telco Big Data • Challenge
Volume is extremely large
Consisting of BSS data and OSS data
• Solution
• Example: churn prediction
• Retaining customers is key for telco companies
• Prediction rate = 90% for top 10K users
• Increased retention rate from 15% to 35%
• Extracting useful features from both OSS and BSS data

Intelligent Banking • Case study:
Commercial Bank A
Traditionally, less than one hundred features
Currently, thousands even millions of features developed by Huawei’s tool
Increased by a factor of six the success rate of targeted advertisements.
• Challenge
• Data sparse, scale is large
• Solution • Automatic feature engineering
