Implement a linear classifier with Iris data. (https://archive.ics.uci.edu/ml/datasets/iris) Step 1: Use only the first 100 samples (only two classes) to make it binary class data. Step 2: Use hold-out method. Shuffle the samples and select the first 10 samples for test (90 samples are training data). Step 3: Repeat Step 2 for 100 times, then calculate accuracy on average.
