What is program analysis?The process of automatically evaluating a computer program's performance in terms of a property like correctness, robustness, safety, and liveliness is known as program analysis.The two primary focuses of program analysis are program optimization and program correctness.In the former, emphasis is placed on ensuring that the program operates as intended, whereas in the latter, it is placed on improving program performance while consuming less resources.Static program analysis is performed before or after the program is run, dynamic program analysis is performed while the program is executing, or both can be done simultaneously.The four sorts of reasoning that make up the core of program analysis tools are:Concrete code-derived runs,Seeing runs in concreteUsing observations to extrapolate abstractions, andConducting experiments to pinpoint the causes of certain effects.Therefore, the amount of time a user spends on your website does not qualify as a dimension when you use analytics programs on it.

A machine learning model is trained to predict tumor in patients. The test dataset consists of 100 people. Calculate the Accuracy, Precision, Recall and F1-Scorebased on the given confusion matrix. What is the weakness and strength of this model?
Answer:
Explanation:
Confusion matrix:
Actual Negative Actual Positive
Predicted Negative 50 20
Predicted Positive 10 20
Accuracy = (50 + 20) / 100 = 0.7
Precision = 20 / (20 + 10) = 0.67
Recall = 20 / (20 + 20) = 0.5
F1-Score = 2 * (Precision * Recall) / (Precision + Recall) = 0.57
A model's strength is measured by its ability to accurately predict the positive class, which is measured by precision, and by its ability to find all the positive instances, which is measured by recall. A model's weakness is measured by its ability to accurately predict the negative class, which is measured by the true negative rate.
In this case, the model has a high accuracy of 0.7, however, it has a low precision of 0.67 and recall of 0.5, and a low F1-Score of 0.57. This means that the model is not very good at correctly identifying positive cases, and is also not very good at correctly identifying negative cases. This model is not a good model for this problem and it is needed to improve the model.

Explanation:
according to the map below, which of the following is the most likely location of the famc lignite mine?
The most likely location of the FAMC lignite mine according to the map is Latrobe Valley Basin.
Lignite has a higher volatile matter content than higher-ranking coals, making it easier to convert into gas and liquid petroleum products. Unfortunately, its high moisture content and susceptibility to spontaneous combustion make transportation and storage difficult. Water removal processes reduce the risk of spontaneous combustion to the same level as black coal, increase the calorific value of brown coal to a level comparable to or better than most black coals, and significantly reduce the emissions profile of 'densified' brown coal to a level comparable to or better than most black coals. However, removing the moisture raises the final cost of the lignite fuel.
When exposed to air, lignite degrades rapidly. This is referred to as slacking or slackening.
