Machine Learning & Data Science Dictionary – Part 3
Jupyter Notebook – It is a web-based computing platform used to create and share documents.
K-means – It is an unsupervised learning algorithm used to group data points to the nearest centroid through distance.
Keras – It is an open-source library developed by Google for implementing neural networks.
K-nearest Neighbours (KNN) – It is a supervised machine learning algorithm used for regression and classification tasks. It is used to predict the test data set by calculating the distance between the current training data points.
Kubernetes – It is an open-source platform for automating application deployment, scaling, and management.
Labelled dataset – It is the data that has a “label”, “class”, or “tag” associated with it.
Lasso Regression – It is the process of shrinking or regularizing to avoid overfitting to minimize prediction error.
Linear Regression – It is used to make predictions on continuous dependent variables with the use of independent variables.
Logistic Regression – It is used to predict the categorical dependent variable using independent variables to classify outputs, which can only be between 1 and 0.
Log Loss – It measures the performance of a classification model, where the output is a probability with values between 1 and 0.
Long Short Term Memory Networks – It is a type of Recurrent Neural Network which can learn and memorize long-term dependencies. It aims to remember past information for long periods.
Machine Learning – It is a field of study & process where models use historical data as an input to predict the outcomes.
Machine Learning Operations (MLOps) – It is a core function of Machine Learning engineering that focuses on taking ML models to production and maintaining and monitoring them.
Management information system (MIS) – It is a computer system consisting of hardware and software that serves as the backbone of the operations of an organization.
Maximum Likelihood Estimation – It is a probabilistic framework to get more accurate parameter estimates.
Mean – It is an average value of all the numbers in the data.
Mean Absolute Error – Also called L1 regularization, it computes the mean of errors between labelled and predicted data.
Mean Square Error Loss – It is known as L2 regularization and tells how close a regression line is to a set of data points.
Median – It is the middle value in an ordered list from smallest to largest.
Mode – It is a value that appears most frequently in input or output data sets.
Model selection – It is the process of selecting a model from a set of available model selections.
Monte Carlo Method – It is a mathematical technique used to estimate the possible outcomes of an uncertain event.
Multi-Class Classification – The classification problems with more than one class in the target variable.
Multilayer Perceptrons – It is a feedforward artificial neural network where inputs are fed into the Neural Network to generate outputs.
Multivariate Analysis – It is the process of comparing and analyzing the dependency of multiple variables over one another.
Naive Bayes – It is a process based on the Bayes Theorem by using a classifier which assumes the independence between attributes of data points.
NaN – It stands for ‘not a number’ and refers to a numeric value that is undefined or unrepresented. This is considered misrepresented or missing in a dataset.
Natural Language Processing – NLP is the ability of a computer to detect and understand human language through speech and text.
Neural Network – It is a network made up of neurons that contain three different layers: an input layer, an output layer, and hidden layers.
NoSQL – It stands for Not only SQL and is a database that provides storage and retrieval of data.
Nominal variable – It is a type of the variable used to categorize, label, or name particular attributes that need to be measured.
Normal distribution – It is a probability distribution function that represents the distribution of variables in a bell-shaped graph.
Normalization – It is a scaling technique used to shift and rescale data into the range [0, 1].
NumPy – It is a library used for Python with mathematical functions in processing linear algebra, multidimensional array objects, and matrix functions.
One Hot Encoding – It is a process where categorical variables are converted into a form for ML and deep learning algorithms to improve the predictions and accuracy of a model.
Ordinal variables – These are the variables that have discrete values with some form of order involved.
Outlier – It is the observation far away from the overall pattern in a sample.
Overfitting – It happens when a statistical model fits precisely against its training data. It is a modelling error when a function too closely includes a limited set of data points.
Pandas – It is an open-source Python library for data analysis & manipulation.
Parameters – These are measurable factors that define a system and the part of a model that is learned from past training data.
Precision – It is the measure of total actual positive cases and the quality of a positive prediction made by the model.
Predictive Modelling – The process of using a mathematical approach to predict outcomes or future events by analyzing patterns in a given set of data.
The Predictor Variable – It is the variable used to predict dependent variables.
Principal Component Analysis – It is a technique used to reduce the dimensionality of datasets by increasing model interpretability without minimizing information loss.
Probability distribution – It is a statistical function that describes all possible values and their occurrence.
P-value – It is the probability that the results from your sample data occurred by chance. Therefore a low p-value is good.
