Robust-first Computing Wiki

Implement a convolutional neural network (CNN) that will be able to classify an input image. It will use the layers based around a very basic CNN including: convolution layer, pooling layer, rectifier layer, and a fully-connected layer. This will have to start off static in the MFM, as passing data would be very difficult otherwise. This will require five elements that I will go into detail further down this page.

• Neuron:
  • Will contain the weights from the pre-trained network that it will be using to classify the image
  • Deal with all of the computations for the convolution, pooling, normalization, and fully-connection
  • Will update the neighboring pixels based on the output from the computation
• Pixel
  • Holds the gray-scale value for 7 pixels, then has space for a couple more bits for flags in the future
• Router
  • Will hold routing information based on which way for a packet to go based on where it is going
• Path
  • Will help with guiding the packets to the specified Neuron cluster
• Packet
  • Will hold information about 7 pixels, and will follow the path and routers to its destination to deliver the information

• Main Goal: Run a simple MNIST example with smaller training set of 0's, of image size 18×18(?)
  • First Step: Get a layout that will work for the CNN (X)
  • Second Step: Get 7 packets sent from one cluster of pixels to another cluster of pixels ( )
  • Third Step: Get pixel packets from all other clusters of pixels to one Neuron cluster, then run that specific convolution layer over all pixels from the image ( )
  • Fourth Step: Get the above goal to work with all clusters of Neurons ( )
  • Fifth Step: Implement the pooling step ( )
  • Sixth Step: Set-up the rectifier layer ( )
  • Seventh Step: Create the fully-connected outcome ( )
  • Eight Step: Classify the image ( )

Week 7 Update:

• Now understand the concept of CNN better through messing with tiny_dnn
• Found “final” design for blocks of CNN
• Will now work on communication between the blocks in the CNN
• Also will work on fixing a size for the CNN based around a smallish image
