The answer is a Scanning Electron Microscope
It is important to obtain and prepare proper samples when using SEM. The sample’s size, state, and shape are things that should be considered before the sample preparation. Some samples need to be coated. Most metals require no preparation since they can easily conduct electricity. Non-metals, however, needs to be coated with a thin layer of gold. Gold is the ideal non-metal and works most of the times.
Answer:
a. This is an instance of overfitting.
Explanation:
In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.
