| Question | Answer |
|---|---|
| Feature net variant 1 is also known as the | McClelland and Rumelhart model |
| M and R model is known to be ___ | complex |
| the complex feature net goes in what directions? | Forward, back, and within the same level |
| T or F, higher level word detectors can influence lower level detectors | T |
| T or F, Feedback is not present everywhere in the brain | F |
| T or F, the complex feature net is only inhibitory | F |
| What is another name for variant 2 | Recognizing 3D models |
| what are geons? | shapes |
| what are objects | geons combined |
| What is the hiearchy of detectors | Object model-> Geon assembles-> Geon detectors-> Feature detectors |
| define the role of object model | recognition of a complete object |
| define geon assemblies | relations between geons |
| define feature detectors | curves and edges |
| Independent viewpoint | geon =identified object model activated= object recognition |
| Define Partial input | most objects can be recognized from few geons which doesn't prevent object recognition |
| where are object detectors located? | in the inferior temporal cortex |
| T or F, Viewpoint dependent could trigger independent cells | T |
