4.1. Image Classification Using One-Hidden-Layer ANN on Features Extracted from Image Data
- The number of neurons in the hidden layer must be established on a somehow empirical basis. The number of neurons in the hidden layers may be important in order to extract the meaningful features of the image.
- Every training session can produce different results because of the fact that the initial weights and biases of each neuron are set randomly. Training the network with the same number of neurons on the same input datasets can produce different results when tested with unlabeled data.
- The number of training epochs has to be well established in order to avoid overfitting. If overfitting occurs, the network will be less successful in classifying unlabeled data.
4.2. Image Classification Using One-Hidden-Layer ANN on Image Data
4.3. Image Classification with Autoencoders on Image Data
- What kind of image processing and classification method would be successful?
- What are the costs for such a system to be implemented?
