We explore a neural network approach to handwritten digit recognition. A theoretical explanation of feed-forward networks is presented. Several fully-connected, feed-forward neural nets of varying size are trained on images obtained from the NIST online database. Performance of the systems is analyzed and compared to that of Principal Component Analysis, which is also given a brief theoretical outline. The best-performing system was a 50-unit network, which had a recognition error of 6.95% on the test data. PCA achieved a best error rate of 14%
