**By:**TDG Network**Updated on:**January 19, 2024, 11:02 pm IST

AI, machine learning, deep learning, GPT, and generative AI are some major buzzwords that have been trending all over the Internet for nearly a decade. Artificial intelligence is the epitome of modern technology, given its wildfire-like spread across every economic sector. According to a simulation by reputed consultancy firm McKinsey, by the year 2030, 70 percent of companies across the primary, secondary, & tertiary sectors will be adopting at least one form of AI technology or the other. The adoption rate is expected to be relatively rapid, and according to a stimulation conducted by McKinsey, the technology is expected to deliver an additional economic output of about $13 trillion.

So, what makes AI so incredibly effective? What makes the technology so versatile and easily adaptable across many different industries? If you are an aspiring machine learning engineer, you must know that mathematics and statistics are two central pillars of AI and machine learning. In this article, experts of Homework Helper.com, USA’s statistics homework help service, offer some crack insights on the most important statistical techniques powering AI models & systems all over.

**How Statistics Helps AI Process & Predict Things?**

Statistical models and techniques allow AI systems to carry out different operations without being explicitly programmed. AI models use stat techniques to learn by poring vast data volumes and making predictions, analyses, judgments, etc. The nature, quality, and quantity of data determine the accuracy of predictions, while specific parameters called hyperparameters determine the art of learning the machine learning model.

Statistics defines the theoretical frameworks upon which machine learning algorithms are based. The science of statistics involves careful analysis, interpretation, and organization of data. The field offers many tools and techniques for identifying and understanding patterns & trends in vast data sets. This makes it possible for AI models to understand and summarize any kind and quantity of data, no matter how complicated and extensive the underlying phenomenon generating it. Work hard, and if need be, get some expert statistics homework help from reputed statistics homework help services.

Let’s look at the key statistical concepts used in machine learning.

**Inferential Statistics & Probability-Based ML Algorithms**

As you may already know, inferential statistics makes inferences and predictions about large data populations from smaller samples & subsets.

**Linear Regression****🡪**This supervised learning algorithm establishes the relationship between dependent and independent variables. The technique uses hypothesis tests and estimates the linear relationship/equation coefficients between the dependent and independent variables to make predictions and extract valuable insights from a dataset.

**Logistic Regression****🡪**Similar to linear regression, logistic regression is primarily used to determine a decision-making rule for accurately classifying a mixed dataset. The technique estimates the probability of data belonging to a particular category based on the values of independent variables.

**Decision Trees****🡪**This a particularly versatile machine learning algorithm that slits a dataset according to specific features. The result of the split is a tree-like structure that is then used by a classification or regression algorithm.**Random Forest****🡪**The random forest algorithm is an enhanced version of the decision tree algorithm. The technique uses sampling to select random features of a dataset for building trees. The different trees’ predictions are then accrued to deliver an accurate, final prediction.**Support Vector Machine****🡪**This is a powerful algorithm frequently used for classification and regression. The primary principle of this method involves creating a boundary called the hyperplane for demarcating the different kinds of data in a group.**K-nearest Neighbors****🡪**The K-nearest neighbors algorithm is yet another simple but effective process used for data regression and classification in machine learning. It is also used in data clustering as it uses distance measures for determining the similarity/dissimilarity between points in a data set.

**Descriptive Statistical Techniques in ML**

Descriptive statistical techniques allow for effective and intuitive visualization of data. Some of the most utilized descriptive techniques are 🡪

**Measures of Central Tendency****🡪**Mean, median, and mode allow users to identify the central representative values in a dataset. They help impute missing values and identify potential outliers in a dataset.

**Variance & Standard Deviation****🡪**These two methods enable users to determine the spread/dispersion of data around a central representative value. Both variance and standard deviation are effective indicators of variability in machine learning training/testing/input data and output.

**Measures of Spread****🡪**Measures of spread such as range, interquartile range, and percentile inform users of the overall distribution of data values. They are also especially useful in detecting outliers, which can substantially affect model training and output.

Well, those were some of the most heavily utilized statistical techniques by machine learning systems. And that’s all the space for this article. Hope it was an informative read for one & all. Mastering machine learning is not easy and requires complete mastery of both descriptive & inferential statistics.
