What do we want to do?
• MiNiFi ingests camera images and
sensor data
• MiNiFi executes algorithms at the edge
• Run Trained Inception Classification to
recognize objects in image
• Apache NiFi stores images, metadata
and enriched data in Hadoop
• Apache NiFi ingests social data and
REST feeds
• Apache OpenNLP and Apache Tika for
textual data

Recommendations
• Model Training
• Install CPU Version on CPU YARN Nodes
• Install GPU Version on Nvidia (CUDA)
• Do training on GPU YARN Nodes where possible
• Model Applying
• Apply Model on All Nodes and Trigger with Apache NiFi
• What helps Hadoop and Spark will help TensorFlow.
• More RAM, More and Faster Cores, More Nodes.
• Try YARN 3.1 Containerized TensorFlow.

Aggregate all data from sensors, drones, logs, geo-location devices,
machines and social feeds
Collect: Bring Together
Mediate point-to-point and bi-directional data flows, delivering data
reliably to Apache HBase, Apache Hive, HDFS, Slack and Email.
Conduct: Mediate the Data Flow
Parse, filter, join, transform, fork, query, sort, dissect; enrich with weather,
location, sentiment analysis, image analysis, object detection, image
recognition, voice recognition with Apache Tika, Apache OpenNLP,
TensorFlow and Apache MXNet.
Curate: Gain Insights
