Summarize findings to stakeholders: Using ROC AUC score to evaluate model performance. Learn more. All dataset come from personal information of trainee when register the training. Data set introduction. This dataset contains a typical example of class imbalance, This problem is handled using SMOTE (Synthetic Minority Oversampling Technique). A more detailed and quantified exploration shows an inverse relationship between experience (in number of years) and perpetual job dissatisfaction that leads to job hunting. The whole data is divided into train and test. In our case, the correlation between company_size and company_type is 0.7 which means if one of them is present then the other one must be present highly probably. Most features are categorical (Nominal, Ordinal, Binary), some with high cardinality. It still not efficient because people want to change job is less than not. We used the RandomizedSearchCV function from the sklearn library to select the best parameters. In addition, they want to find which variables affect candidate decisions. to use Codespaces.

What is the total number of observations? Simple countplots and histogram plots of features can give us a general idea of how each feature is distributed. Then I decided the have a quick look at histograms showing what numeric values are given and info about them. though i have also tried Random Forest. Metric Evaluation : Training data has 14 features on 19158 observations and 2129 observations with 13 features in testing dataset. As seen above, there are 8 features with missing values. To predict candidates who will change job or not, we can't use simple statistic and need machine learning so company can categorized candidates who are looking and not looking for a job change. We can see from the plot there is a negative relationship between the two variables. This dataset consists of rows of data science employees who either are searching for a job change (target=1), or not (target=0).
