The rising area of data-centric engineering, which aspires to improve current engineering practice by applying state-of-the-art statistics, Machine Learning, and AI technologies, has posed various new theoretical and methodological issues. This research group collaborates with practitioners and theoreticians to build statistical Machine Learning methods to meet the ever-increasing demands of engineering sciences.

What is Statistical Machine Learning?

Statistics is a collection of methods that may be used to solve key data queries.

You may turn basic observations into information that you can comprehend and share using descriptive statistical approaches. Inferential statistical approaches can be used to make inferences from small samples of data to entire domains.

You must be familiar with statistical approaches as a Machine Learning practitioner.

Raw observations include data, but they are neither information nor knowledge in and of themselves.

Statistics and Machine Learning

In this session, you’ll study the five reasons why Machine Learning practitioners should improve their statistical knowledge.

1. Statistics in Data Preparation

In order to prepare training and testing data for your Machine Learning model, you’ll need to use statistical approaches.

This includes techniques for:

  • Detecting outliers
  • Imputation of missing values
  • Sampling of data
  • Data scalability
  • Encoding that can be changed.

To assist you in understanding the approaches to use while doing these activities, you’ll need a basic grasp of data distributions, descriptive statistics, and data visualization.

2. Statistics in Model Evaluation

When evaluating the competence of a Machine Learning model on data that was not observed during training, statistical approaches are necessary.

This includes techniques for:

  • Sampling of Data.
  • Resampling of Data.
  • Experimental design.

Machine Learning practitioners typically understand resampling techniques like k-fold cross-validation, but not the logic for why this method is essential.

3. Statistics in Model Selection

When choosing a final model or model configuration for a predictive modeling challenge, statistical methodologies are necessary.

These include techniques for:

  • Examining the data to see whether there is a major difference between them.
  • Measuring the magnitude of the difference between the two outcomes.
  • In this instance, statistical hypothesis testing may be performed.

4. Statistics in Model Presentation

For presenting the skill of a final model to stakeholders, statistical methodologies are essential.

This includes techniques for:

  • Summarizing the model’s average predicted performance.
  • Calculating the predicted variability of the model’s competence in practice.
  • This might include confidence intervals and other estimating data.

5. Statistics in Prediction

When producing a forecast with a finished model on new data, statistical procedures are necessary.

This includes techniques for:

  • Calculating the prediction’s projected variability.
  • Estimation statistics, such as prediction intervals, may be included.

Why is Statistics Important to Machine Learning?

Statistical approaches are necessary to operate successfully via a Machine Learning predictive modeling project, it is fair to declare.

Machine Learning is 90% based on statistical concepts. The heart of the study is statistical ideas and statistical reasoning. If you truly want to grasp things like overfitting, cross-validation, and its applications, learnability constraints, adaptive algorithms, and why LASSO is a good idea (if at all), the SML software can assist.

The SML program allows you to solidify your knowledge of probability theory and statistics. The distinction between Machine Learning and statistics is now blurrier than it has ever been. Statisticians publish in Machine Learning publications and present at Machine Learning conferences, and the reverse is also true. After all, both approaches are attempting to find better ways to develop better models, which would result in more accurate forecasts. 

In reality, the need for rigorous algorithm analysis is more than ever, and for a good reason: a strong grasp of algorithms is required to provide a firm foundation for the tower of results that will be erected on top of it not to collapse. Although empirical data is valuable, it can never give the entire picture.

Here are 10 scenarios in which statistical approaches are employed in a Machine Learning project.

Problem Framing: Exploratory data analysis and data mining are required.

Data Understanding: Use of summary statistics and data visualization is required.

Data Cleaning: Outlier identification, imputation, and other techniques are required.

Data Selection: Data sampling and feature selection strategies are required.

Data Preparation: Data transformations, scaling, encoding, and other techniques are required.

Model Evaluation: Experimentation and resampling approaches are required.

Model Configuration: The use of statistical hypothesis testing and estimated statistics is required.

Model Selection: The use of statistical hypothesis testing and estimate statistics is required.

Model Presentation: The use of estimated statistics such as confidence intervals is required.

Model Predictions: The use of estimated statistics such as prediction intervals is required.

Machine Learning Engineer Salary in USA and India

Glassdoor informs the national average income for a Machine Learning Engineer in the United States is $1, 31,001. In India, the average income for a Machine Learning Engineer is ₹8,97,850 per year(Glassdoor).

The average Machine Learning engineer’s income in the United States is $112,837 per year. Their salaries begin at $76,000 per year and rise to $154,000 per year. The bonus for this position may be up to $24,000, and the profit share could be up to $41,000. While firms all over the world are seeking AI and ML expertise, the market supply is rather short. As a result, this function draws such a high price.

Conclusion

Machine Learning is an interdisciplinary field that employs statistics, probability, and algorithms to extract information from data and provide insights that may be utilized to create intelligent systems.
