Hierarchical clustering is a type of ______________ technique.
Clustering
How are batch learning algorithms typically used?
To predict continuous values in batch mode
How is the line of best fit calculated using the least squares method?
By minimizing the sum of the squares of the errors between the data points and the line of best fit
How can the problem of producing suboptimal results if the clusters are not spherical be addressed in the k-means algorithm?
By using a hierarchical clustering approach
How does supervised learning differ from unsupervised learning?
Supervised learning involves labeled data, while unsupervised learning involves unlabeled data
How does the k-means algorithm determine which data points belong to which cluster?
By computing the distance between data points and the centroid of each cluster
How does the least squares method handle outliers in the data set?
It ignores them
How can the sensitivity to the initial placement of centroids be addressed in the k-means algorithm?
By using the k-means++ initialization method
Can the Naive Bayes classifier handle missing or incomplete data?
Yes, it can handle missing or incomplete data
Hierarchical clustering can be either
Agglomerative, divisive
Hierarchical clustering is a type of ______________ clustering.
Hierarchical
How is KNIME different from other data analysis tools?
t allows users to build custom data pipelines
How can users access the KNIME Marketplace?
All of the above
How does the Naive Bayes classifier calculate the probability of a data point belonging to a particular class?
By using the Bayes theorem
How is the Hebb rule used in the training of a neural network?
It is used to adjust the weights of the neural network based on the input and output
