Quick Navigation
FEATURE SELECTION#1
The process of selecting a subset of relevant features for model building, improving accuracy and reducing overfitting.
CUSTOMER CHURN#2
The loss of customers over time, often measured as a percentage of total customers, critical for business strategy.
RECURSIVE FEATURE ELIMINATION (RFE)#3
A feature selection technique that recursively removes the least important features based on model performance.
LASSO#4
A regression analysis method that performs both variable selection and regularization to enhance prediction accuracy.
MODEL PERFORMANCE#5
A measure of how well a machine learning model predicts outcomes, often evaluated using metrics like accuracy and F1 score.
PREDICTIVE MODELING#6
The process of creating a model that forecasts future outcomes based on historical data.
SCIKIT-LEARN#7
A popular Python library for machine learning that provides simple and efficient tools for data mining and analysis.
CROSS-VALIDATION#8
A technique for assessing how the results of a statistical analysis will generalize to an independent dataset.
DATA VISUALIZATION#9
The graphical representation of information and data, making complex data more accessible and understandable.
FEATURE IMPORTANCE#10
A technique that ranks features based on their contribution to the model's predictive power.
HYPERPARAMETER TUNING#11
The process of optimizing the parameters of a machine learning model to improve performance.
DATA STORYTELLING#12
The practice of using data to tell a compelling story, making insights more relatable and actionable.
MODEL EVALUATION METRICS#13
Quantitative measures used to assess the performance of a machine learning model, such as precision and recall.
OVERFITTING#14
A modeling error that occurs when a model learns the training data too well, failing to generalize to new data.
UNDERFITTING#15
A modeling error that occurs when a model is too simple to capture the underlying trend of the data.
VARIABLE SELECTION#16
The process of selecting a subset of relevant features from a larger dataset to improve model performance.
DATA PREPROCESSING#17
The steps taken to clean and prepare raw data for analysis, ensuring accuracy and consistency.
TRAINING SET#18
A subset of data used to train a machine learning model, allowing it to learn patterns and relationships.
TESTING SET#19
A separate subset of data used to evaluate the performance of a trained machine learning model.
BUSINESS STRATEGY#20
A plan of action designed to achieve specific business goals, often informed by data analysis.
RETAINED CUSTOMERS#21
Customers who continue to engage with a business, crucial for sustaining revenue and growth.
INSIGHT COMMUNICATION#22
The process of conveying analytical findings effectively to stakeholders, ensuring understanding and action.
ANALYTICAL REPORTING#23
