Which of the following is a method of experimentally evaluating the effectiveness of classifiers:

Stratified cross validation

Specificity

Random boosting

Hold-out

Random Forest:

Generates models that have the same weight

Uses return draws to create datasets for which models are generated

Uses a random subset of attributes from which the next decision node is determined

Generates a sequence of models better and better adapted to "difficult" examples

In the dataset (ExampleSet in RapidMiner), an attribute with role:

"Outlier" is required to run an anomaly detection algorithm such as LOF (Local Outlier Factor)

"Regular" requires discretization before running the clustering algorithm

"Label" is required to evaluate the quality of the classifier on the test set

"Label" is required to build a decision tree model

Indicate the true sentences related to eXplainable Artificial Inteligence (XAI).

Explainable artificial intelligence is needed because scientists do not understand how advanced machine learning methods work.

Explainable artificial intelligence methods are those machine learning models that are interpretable.

Methods of explainable artificial intelligence can be independent of the machine learning model used.

The decision tree is not an interpretable model, so it is necessary to apply methods of explainable artificial intelligence to understand on what basis the decision is determined by it

Hierarchical agglomerative clustering algorithm:

Minimises the average distance of objects from group centres

Determines the division into groups, starting with one group containing all objects, which is subdivided until each object belongs to a separate group

Derives a dendrogram illustrating the clustering process

Can correctly identify interlocking concave groups

The effect of the k-means clustering algorithm is:

Fuzzy partition matrix

Dendrogram

Matrix of cluster prototypes

Partitioning into clusters and a collection of objects defined as noise

Boosting:

Generates models that have the same weight

Generates a sequence of models better and better adapted to “difficult” examples

Uses a meta-model to combine the decisions of the ensemble models

Generates a homogeneous ensemble of models

Stacking:

Uses a meta-model to combine the decisions of the ensemble models

Generates a sequence of models where the next model fits to the error made by the previous model

Generates a sequence of models better and better adapted to “difficult” examples

Generates a homogeneous ensemble of models

The effect of the DBSCAN clustering algorithm:

Matrix of cluster prototypes

Fuzzy partition matrix

Dendrogram

Partitioning into clusters and a collection of objects defined as noise

Bagging:

Generates models that have the same weight

Uses return draws to create datasets for which models are generated

Works well for models that strongly fit the data (overfitting)

Generates a sequence of models better and better adapted to “difficult” examples

The effect of the hierarchical agglomerative clustering algorithm is:

Fuzzy partition matrix

Dendrogram

Matrix of cluster prototypes

Partitioning into clusters and a collection of objects defined as noise

DBSCAN clustering algorithm:

Maximises the average distance of objects from group centres

Should be executed several times for different initial conditions, as it may get “stuck” in a local minimum

Derives a dendrogram illustrating the clustering process

can correctly identify interlocking concave groups

K-means clustering algorithm:

Maximises the average distance of objects from group centres

Should be executed several times for different initial conditions, as it may get “stuck” in a local minimum

Requires specifying the number of groups to be identified

can correctly identify interlocking concave groups

Please indicate the true sentences regarding the quality assessment of classifiers

Leave-one-out is a measure of classifiers quality

Cross-validation is a method of experimentally evaluating the performance of classifiers

Accuracy is a measure of quality of classifiers

AUC is a method of experimental evaluation of classifier performance

Tick correct answers

Noninterpretable fuzzy rule base deteriorates the generalization ability of the fuzzy system

The curse of dimensionality is a disadvantage of the grid partition of the input domain

We join descriptors in premises with a T-norm

The grid partition is the most common technique for the input domain partition

Please indicate the true sentences about automatic learning

AML uses hyperparameter optimalization to generate models

AML uses meta-learning to determine the features that will best represent the data that is being analyzed

AML involves generating a predictive model without the need to indicate a value of the decision attribute

AML uses meta-learning to select the best ml methods for the data being analyzed

Evaluate whether it is true or false (Gausser-Müller kernel regression function estimator)

It is possible that estimator value could be interminate

The smoothing parameter value does not influence the final result significantly

Weighted average may be considered as the method interpretation (kernel function values are weights)

The method estimates values only for such arguments that are members of the training set

Tick correct sentences

In neuro-fuzzy systems we can only use differentiable descriptors

It is possible to use a fuzzy set with an infinite support and an empty core in (neuro-) fuzzy systems

It is possible to model relations "greater than", "less than", eg. The temperature is less than...
