How Is Applied Statistics Used In Artificial Intelligence?
Artificial Intelligence & Machine Learning
Artificial intelligence (AI) is the field of developing intelligent algorithms capable of doing tasks that would ordinarily need human intelligence. These include voice recognition, decision-making, and image classification.
One of the key components of AI is the ability to learn from data, which is where applied statistics comes into play. Applied statistics is the branch of statistics that involves the application of statistical methods to real-world problems.
This article goes in-depth into data collection, model selection, descriptive statistics, and why applied statistics will see a renaissance.
Data Collection And Preprocessing
Data collection and preprocessing are critical components of applied statistics in AI. Raw data is often unorganized and contains errors and inconsistencies, and preprocessing is required to clean, transform, and prepare the data for use in statistical models.
In AI, the data quality is directly related to the quality of the resulting model, and proper data preprocessing is essential for building accurate and reliable models.
Data collection is the process of gathering raw data from various sources. In AI, data collection is often performed using sensors, cameras, and other devices to capture and record data.
For example, a self-driving car may use cameras and lidar sensors to collect data about its surroundings, such as the location of other cars and the position of pedestrians. Other data sources may include databases, surveys, and social media feeds.
Once data has become collected, preprocessing becomes required to clean and transform it. So one can use it in statistical models. Data cleaning involves identifying and correcting data inconsistencies, such as missing or incorrect values, outliers, and duplicates.
Data transformation involves converting the data into a suitable format for analysis, such as scaling or normalizing the data or converting categorical variables into numeric variables.
Preprocessing may also involve feature engineering. Which is the process of selecting and creating features relevant to the problem becoming addressed. For example, in an image classification problem, one may select a color, texture, and shape to help distinguish between different classes of images. Feature engineering can be complex and time-consuming, but it is essential for building accurate and robust models.
Python, as a programming language, has an interesting intersection of data processing and collection with machine learning. Here is a fascinating article on how these practices intersect with each other.
Descriptive Statistics
Descriptive statistics is a branch of applied statistics that involves summarizing and visualizing data. In AI, descriptive statistics become used to gain insights into large and complex datasets. In addition, identify patterns and trends that one can use to inform decision-making.
One of the most common ways of summarizing data is through measures of central tendency, such as the mean, median, and mode. These metrics offer information about the typical or average value of a dataset. For example, in a dataset of the heights of a population, the mean height would provide information about the typical height of a person in that population.
Another important type of descriptive statistic is measures of variability, such as the range, variance, and standard deviation. These measures provide information about the spread or distribution of the data.
For example, a high standard deviation in a dataset of test scores indicates that the scores became widely spread out. In contrast, a low standard deviation indicates that the scores became tightly clustered around the mean.
Visualization is also an important tool in descriptive statistics. One can use graphs and charts to represent data in a way that is easy to understand and interpret. For example, a person can use a histogram to visualize the distribution of a dataset, while one can use a scatter plot to visualize the relationship between two variables.
In AI, descriptive statistics become used to gain insights into large and complex datasets and to identify patterns and trends that one can use to inform decision-making.
Beyond descriptive statistics, if you are someone getting into model selection; here is a simple guide to help you get started with a step-by-step guide to help you better understand the process.
