(GMT+8) * 11/09為超過 Kaggle simple baseline 的加分截止期限 * 在做 P4及P5時，請大家先看過這個關於 <a href="https://blog.keras.io/how-convolutional-neural-networks-see-the-world.html" target="_blank">visualization 的 tutorial</a> <hr> In this assignment, you will practice using Deep Learning libraries to experience the power of Neural Net. The requirements of this assignment are as follows: ## <a href="" target="_blank">P1: Build Convolution Neural Network (1%)</a> *[Accuracy]* Build CNN model, and tune it to the best formance as possible as you can. Record your model structure and training procedure. ## <a href="" target="_blank">P2: Build Deep Neural Network (1%)</a> *[Accuracy]* Using the same number of parameters as above CNN, build a DNN model to do this task. Record your model structure and training procedure. Explain what you observed. ## <a href="" target="_blank">P3: Analyze the Model by Confusion Matrix (1%)</a> *[Analysis]* Observe the prediction of your validation data( 10% ~ 20% of training data is OK ). Plot the prediction into confusion matrix and describe what you observed. ## <a href="" target="_blank">P4: Analyze the Model by Plotting the Saliency Map (1%)</a> *[Analysis]* Plot the saliency map of original image to see which part is important when classifying ## <a href="" target="_blank">P5: Analyze the Model by Visualizing Filters (1%)</a> *[Analysis]* Use Gradient Ascent method mentioned in class to find the image that activates the selected filter the most and plot them.
