Data preparation in machine learning is cleaning, manipulating, and structuring raw data so that it may be used by machine learning algorithms. The method covers tasks such as dealing with missing values, scalin
Autoencodersareneural networksdesigned for dimensionality reduction. They work by encoding input data into a compressed, lower-dimensional representation and then reconstructing the original data from this representation. Autoencoders can capture more complex, nonlinear relationships in data, often surpassing...
Featuring engineering looks a little different for categorical variables — for example, one transformation involves encoding categorical variables as numbers so that they can be understood by the machine learning algorithm. Dummy-encoding (vectorization) creates a vector of 0/1 flags of length equal ...
In many ways, the problem of machine learning is a version of thegeneral problem of adaptive evolution, as encounteredfor example in biology. In biology we typically imagine that we want to adaptively optimize some overall “fitness” of a system; in machine learning we typi...
A schema or an ontology is frequently used in knowledge graphs to specify the graph's structure and semantics. Usually based on a taxonomy, an ontology offers a formal representation of the items and their relationships. It aids in encoding the data's meaning for programmatic usage. Reasonings...
Transformer models in classification While typically used for NLP tasks, transformer models have also been applied to classification problems. Transformer models such as GPT and Claude use self-attention mechanisms to focus on the most relevant parts of an input dataset.Positional encodingis used to ...
