  • Global accuracy
    Global accuracy Model accuracy refers to the degree to which a machine learning model correctly predicts the target outcome based on the input data. It is a common classification performance metric used to evaluate the effectiveness of a machine learning model. Model accuracy is typically expressed as a percentage, with 100% accuracy meaning that the model has correctly predicted the target outcome for all examples in the evaluation dataset.

  • Advanced Statistics
    Machine Learning Evaluation Metrics There are many metrics used to evaluate machine learning models, each with their own pros and cons. We can broadly group metrics as classification and regression metrics. Classification Metrics Classification metrics are used to evaluate the performance of machine learning models that are used for predicting discrete values. Before proceeding to explain some frequently-used classification metrics, it is crucial to understand the confusion matrix showPopular
  • Feature importance
    Feature importance NextBrain demonstrates the Sankey diagram for each model. A Sankey diagram is a visual representation of the flow of predictions in a model, showing the relative importance of each feature in the dataset towards the final prediction. The width of each arrow corresponds to the amount of information or resources that is flowing through that particular channel. The colors used in a Sankey diagram indicate which flow separation is most likely. Darker colors are used to indicatePopular
  • Visual Explainability
    Visual Explainability Machine learning methods use statistical learning to identify boundaries. One example of a machine learning method is a decision tree. A decision tree uses if-then statements to define patterns in data. In machine learning, these statements are called forks, and they split the data into two branches based on some value. That value between the branches is called a split point. A split point is the decision tree's version of a boundary. Every fork is adding information aboSome readers
  • Confusion Matrix
    Confusion Matrix A confusion matrix is a table that is used to define the performance of a classification model on a set of test data for which the true values are known. A confusion matrix is a table with four different combinations of predicted and actual values, typically referred to as True Positives (TP), False Positives (FP), True Negatives (TN) and False Negatives (FN). True Positives (TP) are the cases in which the model correctly predicted the positive class. False Positives (FP) arSome readers

  • Column importance
    Column importance Column importance in machine learning refers to the ability to determine which features of the data are most important in predicting the target variable. It is a way to understand the relationship between the input features and the target variable, and to identify which features have the most impact on the model's predictions. We can see a sample feature importance plot below. A Sample Column ImportancSome readers
  • Variable Correlation
    Variable Correlation Correlation between two features refers to the relationship between two variables in a dataset. By plotting one variable agains another on a graph, which will be colored with respect to the target variable, you can distinguish the relationship between two features more distinctively. For instance, we can observe there is a strong positive correlation between Spent and Clicks features for a particular ROAS range on the variable correlation graph below. We can see that forSome readers
  • Pearson Matrix
    The Pearson correlation matrix is a square matrix that provides the pairwise Pearson correlation coefficients between all the variables in a dataset. Pearson correlation measures the linear association between two variables, where a value of 1 indicates a perfect positive linear relationship, a value of -1 indicates a perfect negative linear relationship, and a value of 0 indicates no linear relationship. For example, consider a dataset that contains information about marketing and sales. The PFew readers
  • Model Training History
    NextBrain.ai provides you the steps taken when training model, such as the number of columns and rows that are removed and the training/test set ratio. These information can inform you better about both your data and model. NextBrain will save you the hassle of optimizing your data to best fit to the model, and will take care of nuances that can yield better metric results.

  • Interpreting Data Distribution
    Data distribution When building machine learning models, it's essential to understand the distribution of the data you're working with. Understanding data distribution can help you choose appropriate algorithms and model parameters, identify potential biases, and evaluate model performance. In this article, we'll discuss the basics of data distribution and how to interpret it for machine learning models. What is Data Distribution?

  • Predict
    Predict Prediction in machine learning refers to the process of using a trained model to make predictions on new, unseen data. Given a set of input features, the model generates a prediction for the target variable based on the relationships it learned during the training process. The data type of the features can vary, but it's important to ensure that the data is in a format that can be processed by the model. Some common data types for features include: Numeric: Numeric data can be coFew readers
