1In Dataiku DSS, where do you build and iterate on machine learning models before they affect the project's Flow?
A.The Lab
B.The Wiki
C.The Dashboard
D.The Catalog
Explanation: Machine learning models are created in the Lab, a workspace for drafting visual analyses, ML tasks, and code notebooks. Any work done in the Lab does not change datasets in the Flow until you explicitly deploy it, which keeps experimentation isolated from the production pipeline.
2Which two kinds of machine learning tasks are the core supervised and unsupervised options offered in a Dataiku visual analysis?
A.Regression and forecasting only
B.Prediction and clustering
C.Scoring and labeling
D.Encoding and rescaling
Explanation: A Dataiku ML Task is either a Prediction task, where you predict a single target variable (supervised learning), or a Clustering task, which groups records without a target (unsupervised learning). Both are created from the Lab as part of a visual analysis.
3A data scientist wants to predict apartment price, a numeric value, from features such as size and location. Which prediction type should they choose in Dataiku?
A.Multi-class classification
B.Two-class classification
C.Regression
D.Clustering
Explanation: Regression is used when the target variable is numeric, such as the price of an apartment. Dataiku automatically suggests the prediction type based on the target column, but it can be set explicitly in the target settings.
4When the target column has exactly two possible values, such as 'churned' and 'retained', which Dataiku prediction type applies?
A.Multi-class classification
B.Time series forecasting
C.Regression
D.Two-class classification
Explanation: Two-class (binary) classification is used when the target can take one of two categories, for example presence or absence of an outcome. Dataiku exposes threshold-dependent metrics and a probability threshold specifically for this prediction type.
5Dataiku documentation recommends NOT using multi-class classification when the target has roughly how many or more distinct classes?
A.About 5 classes
B.About 50 classes
C.About 10 classes
D.About 500 classes
Explanation: Dataiku notes that its visual ML cannot handle a very large number of classes and recommends avoiding multi-class classification beyond about 50 classes. With too many classes, per-class data becomes sparse and model quality degrades.
6Which AutoML prediction style in Dataiku trains a few simple models quickly to give you a fast first result?
A.Interpretable Models
B.High Performance
C.Quick Prototypes
D.Expert mode
Explanation: Quick Prototypes is the AutoML prediction style designed for speed; it trains a small set of models with sensible defaults so you can rapidly assess feasibility. It trades depth of optimization for a quick first iteration.
7A team needs the most accurate possible model and can accept long training times and lower interpretability. Which AutoML prediction style fits best?
A.Quick Prototypes
B.Interpretable Models
C.Trivial identity
D.High Performance
Explanation: The High Performance prediction style selects a variety of tree-based models and performs a very deep hyperparameter optimization search, generally producing the best predictive performance at the expense of interpretability and training time.
8In Dataiku's AutoML engine, what does the engine automatically perform in addition to selecting algorithms?
A.Features handling, scaling, missing-value handling, and hyperparameter optimization
B.Only deployment to a Kubernetes cluster
C.Only writing the project's documentation
D.Only exporting the model to ONNX
Explanation: The DSS automated machine learning engine analyzes the dataset and selects feature handling (including categorical and text processing), scaling, missing-value strategies, and runs hyperparameter optimization in addition to choosing algorithms. This minimizes manual setup while still allowing full customization.
9Which algorithm builds many decision trees on random subsets of data and features, then averages or votes across them?
A.K-Means
B.Logistic Regression
C.Random Forest
D.Ridge Regression
Explanation: A Random Forest is an ensemble of many decision trees, where each tree is grown on a random sample of the training set and considers a random subset of features at each split. Predictions are aggregated by averaging (regression) or voting (classification), which generally yields strong results at the cost of explainability.
10In Dataiku's in-memory Python engine, which gradient boosting algorithm includes an early-stopping mechanism that optimizes the actual number of trees?
A.Naive Bayes
B.Decision Tree
C.K-Nearest Neighbors
D.XGBoost
Explanation: XGBoost in Dataiku uses a built-in early-stopping mechanism, so the exact number of trees is optimized up to the configured maximum based on the cross-validation scheme. This prevents unnecessary trees from inflating training and prediction time.

About the Dataiku ML Practitioner Exam

The Dataiku ML Practitioner certification validates the ability to create, evaluate, and tune machine learning models using Dataiku's visual ML tool, deploy a model from the Lab to the Flow, and apply it to score new data. It covers visual machine learning and AutoML (prediction versus clustering, model design, algorithms, hyperparameter tuning), feature handling and preprocessing (rescaling, encoding, missing-value imputation), model evaluation (confusion matrix, precision/recall, ROC/AUC, regression metrics), deployment basics (Saved Models, scoring recipe, API endpoints), and interactive statistics for exploratory data analysis. Candidates must first hold the Dataiku Core Designer certification, which establishes core concepts such as datasets, the Flow, and visual recipes. The free assessment is delivered online through the Dataiku Academy and includes both a multiple-choice exam and a hands-on project.

Dataiku ML Practitioner Exam Content Outline

25%

Visual machine learning and AutoML

Build prediction and clustering ML tasks in the Lab, choose the prediction type (regression, two-class, multi-class), pick AutoML styles such as Quick Prototypes, Interpretable Models, and High Performance, select algorithms including Random Forest, XGBoost, and logistic regression, and run hyperparameter optimization with cross-validation while keeping the test set pristine.

18%

Feature handling and preprocessing

Configure rescaling (Standard and Min-max), categorical encoding (dummy/one-hot, target/impact, frequency, ordinal), missing-value strategies (mean, median, constant, drop rows, or a 'missing' category), datetime cyclical encoding, text handling such as TF-IDF, and semi-automatic feature generation.

22%

Model evaluation and scoring

Read confusion matrices and compute precision, recall, F1, accuracy, and threshold-independent ROC/AUC for classification, plus RMSE and R-squared for regression; compare models on the same test set; diagnose overfitting; and interpret variable importance, partial dependence, and subpopulation analysis.

15%

Data exploration and interactive statistics

Use Statistics worksheets and cards for univariate, bivariate, and multivariate analysis, including histograms, box plots, scatter and mosaic plots, correlation matrices, PCA, distribution fitting, and hypothesis tests such as chi-square and Shapiro-Wilk at a default alpha of 0.05.

12%

Model deployment basics

Deploy a model from the Lab to the Flow as a Saved Model, score new data with the scoring recipe (predicted class plus probabilities), evaluate with the Evaluate recipe and Model Evaluation Store for drift monitoring, manage model versions, and expose prediction endpoints through the API Designer and API Deployer.

8%

Core Designer concepts (prerequisite)

Apply foundational Dataiku concepts carried over from Core Designer: projects, datasets and connections, the Flow pipeline, visual recipes such as Prepare, building datasets, and the separation between the experimental Lab and the production Flow.

Dataiku ML Practitioner Study Tips from Top Performers

1Build real models in the Lab: create a prediction ML task, try Quick Prototypes versus High Performance AutoML styles, and deploy the best model to the Flow as a Saved Model.
2Master feature handling: know when to use Standard versus Min-max rescaling, dummy versus target/impact versus frequency encoding, and which missing-value strategy fits numerical versus categorical features.
3Be fluent in evaluation metrics: distinguish precision, recall, F1, accuracy, and threshold-independent ROC/AUC for classification, and RMSE and R-squared for regression, and understand why accuracy misleads on imbalanced data.
4Practice the scoring workflow end to end: deploy a model, run the scoring recipe on new data, and use the Evaluate recipe and Model Evaluation Store to monitor performance and data drift over time.
5Use interactive statistics worksheets for EDA: univariate and bivariate cards, correlation matrices, PCA, and hypothesis tests with the default alpha of 0.05, knowing you reject the null when p is less than or equal to alpha.
6Review prerequisite Core Designer concepts: datasets, the Flow, visual recipes such as Prepare, and the rule that Lab work does not affect the Flow until you deploy it.
