You are training a classification model with logistic regression.
which of the following statements are true? check all that apply.
•adding a new feature to the model always results in equal or better performanceon examples not in the training set.
•adding many new features to the model makes it more likely to overfit the trainingset.
•introducing regularization to the model always results in equal or better perfor-mance on examples not in the training set.
•introducing regularization to the model always results in equal or better perfor-mance on the training set.

The correct answers are A) Adding a new feature to the model always results in equal or better performance on examples, not in the training set and B) Adding many new features to the model makes it more likely to overfit the training set.

You are training a classification model with logistic regression.

The following statements are true: Adding a new feature to the model always results in equal or better performance on examples, not in the training set and Adding many new features to the model makes it more likely to overfit the training set.

When we are talking about statistical terms, logistic regression is the analysis used when the dependent variable is binary. This allows the researcher to explain and describe this variable and the interval. This logistic regression can be applied in medical research, engineering or social investigation.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
