What is a data generating distribution?

The data generating distribution is the underlaying distribution of the training dataset. For instance, if the samples given are generated by a normal distribution the the normal distribution is the so called generating distribution.

What is a bias in machine learning?

Machine learning bias, also sometimes called algorithm bias or AI bias, is a phenomenon that occurs when an algorithm produces results that are systemically prejudiced due to erroneous assumptions in the machine learning process.

What is data preparation in machine learning?

Data preparation (also referred to as “data preprocessing”) is the process of transforming raw data so that data scientists and analysts can run it through machine learning algorithms to uncover insights or make predictions.

Which type of data is used in machine learning?

Most data can be categorized into 4 basic types from a Machine Learning perspective: numerical data, categorical data, time-series data, and text.

How do we generate data?

Generating Data. Researchers employ two ways of generating data: observational study and randomized experiment. In either, the researcher is studying one or more populations; a population is a collection of experimental units or subjects about which he wishes to infer a conclusion.

What is the difference between data collection and data generation?

In this text, I replace the term “data collection” with “data generation” to emphasize that the researcher arranges situations that produce rich and meaningful data for further analysis. Data generation comprises activities such as searching for, focusing on, noting, selecting, extracting, and capturing data.

What is data bias?

The common definition of data bias is that the available data is not representative of the population or phenomenon of study. Bias also denotes: Data does not include variables that properly capture the phenomenon we want to predict.

What does data preparation mean?

Data preparation is the process of collecting, cleaning, and consolidating data into one file or data table, primarily for use in analysis.

How do you prepare data before machine learning?

Preparing Your Dataset for Machine Learning: 10 Basic Techniques That Make Your Data Better

1. Articulate the problem early.
2. Establish data collection mechanisms.
3. Check your data quality.
4. Format data to make it consistent.
5. Reduce data.
6. Complete data cleaning.
7. Create new features out of existing ones.

What is machine learning ml Accenture?

What is Machine Learning? Machine Learning is a type of artificial intelligence that enables systems to learn patterns from data and subsequently improve future experience.

What is the importance of normal distribution in machine learning?

In Machine Learning, data satisfying Normal Distribution is beneficial for model building. It makes math easier. Models like LDA, Gaussian Naive Bayes, Logistic Regression, Linear Regression, etc., are explicitly calculated from the assumption that the distribution is a bivariate or multivariate normal.

What is normal distribution in data science?

A Data Scientist needs to know about Normal Distribution when they work with Linear Models (perform well if the data is normally distributed), Central Limit Theorem, and exploratory data analysis. As discovered by Carl Friedrich Gauss, Normal Distribution/Gaussian Distribution is a continuous probability distribution.

What is deep generative model in machine learning?

Deep Generative Models. A Generative Model is a powerful way of learning any kind of data distribution using unsupervised learning and it has achieved tremendous success in just few years. All types of generative models aim at learning the true data distribution of the training set so as to generate new data points with some variations.
