Unsupervised Learning

• The model is not provided with the correct results

during the training.

• Can be used to cluster the input data in classes on

the basis of their statistical properties only.

• Cluster significance and labeling.

• The labeling can be carried out even if the labels are

only available for a small number of objects

representative of the desired classes.

Supervised Learning

• Training data includes both the input and the

desired results.

• For some examples the correct results (targets) are

known and are given in input to the model during

the learning process.

• The construction of a proper training, validation and

test set (Bok) is crucial.

• These methods are usually fast and accurate.

• Have to be able to generalize: give the correct

results when new data are given in input without

knowing a priori the target.

What is the difference between the direct and indirect methods of determining generation time with a growth curve?

In the direct method, the cells are enumerated by determining colony-forming units on a Petri dish; in the indirect method, the cell numbers are approximated using a spectrophotometer.


What is the difference between qualtatative and qauntative?

Some methods provide data which are quantitative and some methods data which are qualitative. Quantitative methods are those which focus on numbers and frequencies rather than on meaning and experience. Quantitative methods (e.g. experiments, questionnaires and psychometric tests) provide information which is easy to analyse statistically and fairly reliable. Quantitative methods are associated with the scientific and experimental approach and are criticised for not providing an in depth description. Qualitative methods are ways of collecting data which are concerned with describing meaning, rather than with drawing statistical inferences. What qualitative methods (e.g. case studies and interviews) lose on reliability they gain in terms of validity. They provide a more in depth and rich description.


What are the Difference between Probabilistic sampling methods and non probabilistic sampling methods?

With a probabilistic method, each member of the population has the same probability of being selected for the sample. Equivalently, given a sample size, every sample of that size has the same probability of being the sample which is selected. With such a sample it is easier to find an unbiased estimate of common statistical measures. None of this is true for non-probabilistic sampling.


What is the difference between parameter and statics?

Parameters are variables used in functions or methods to pass information into them, allowing for dynamic input during execution. Statics, on the other hand, refer to variables or methods that belong to a class rather than instances of the class, meaning they retain their value across all instances and can be accessed without creating an object. In essence, parameters facilitate communication within functions, while statics provide shared data or behavior across class instances.


What is the the difference between formal and informal monitoring?

Formal monitoring involves structured and systematic methods of evaluation, often using established criteria and processes, such as performance reviews or compliance audits. It typically follows a predetermined schedule and is documented, ensuring accountability and consistency. In contrast, informal monitoring is more flexible and spontaneous, relying on casual observations and interactions, such as regular check-ins or conversations. This approach can foster open communication and quick adjustments but may lack the rigor and documentation of formal methods.

What are the key differences between supervised and unsupervised data mining techniques and how do they impact the outcomes of the analysis?

Supervised data mining techniques require labeled data for training, while unsupervised techniques do not. Supervised methods are used for prediction and classification tasks, while unsupervised methods are used for clustering and pattern recognition. The choice of technique impacts the accuracy and interpretability of the analysis results.


What are some of the current widespread Machine Learning algorithms?

Machine Learning can be supervised, unsupervised, semi-supervised, or reinforced. From the supervised algorithms, some of the common methods include Naive bayes classifiers and Support Vector Machines. Unsupervised learning includes k-means and hierarchical clustering.

What is unsupervised ror?

Unsupervised ROR (Rate of Return) typically refers to an analysis method in finance where returns on investments are evaluated without predefined labels or categories. In unsupervised learning, algorithms identify patterns and relationships in data without prior training on labeled datasets. This approach can help in clustering investment performance or identifying trends in financial data that may not be immediately apparent. It contrasts with supervised methods, which rely on historical data with known outcomes to train models.
