• Introduction A unit-based computation graph library. Each unit has its own inputs, outputs and corresponding operations. By running a unit, it does the following:

 +------+--------------------+
 | unit |                    |
 +------+                    |
 |<INPUT> => [OP] => <OUTPUT>|
 +---------------------------+

A unit can shared data via inputs or outputs

 +------+--------------------+
 | unit1|                    |
 +------+                    |
 |<INPUT> => [OP] => <OUTPUT>|
 +----------------------\  /-+
                         ||
 +------+----------------\/--+
 | unit2|                    |
 +------+                    |
 |<OUTPUT> <= [OP] <= <INPUT>|
 +---------------------------+

• Example

A formula

y = (a + b) * (-c)

Represent the computation with units, it looks like this

+------+    
|input0|--+                
+------+  |  +--------+    
          +->|unit_add|----+
+------+  |  +--------+    |
|input1|--+                |  +--------+  +------+
+------+                   +->|unit_mul|->|output|
                           |  +--------+  +------+
+------+    +-----------+  |
|input2|--->|unit_negate|--+
+------+    +-----------+

The graph accept stream data, each input changed, the output would be updated.
