The Importance of Machine Learning for Data Scientists

14-Jan-2022

Big Data, Machine Learning (ML), and Artificial Intelligence (AI) are all well-established concepts that have been in relevance for a long time. However, the capacity to apply algorithms and numerical computations to massive data have only lately gained traction.

The same dynamics that have boosted the popularity of data mining are fueling increased interest in machine learning. Increased data volumes and variety, cheaper and more powerful computing processing and cost-effective data storage are a few examples. All this implies that models that can evaluate greater, more intricate data and provide faster, more accurate responses may be generated quickly and automatically - even on a gigantic scale. An organization's chances of recognizing profitable possibilities or avoiding unforeseen risks are improved by developing detailed models.

As it is, Data science encompasses a wide range of topics, including Machine Learning. Data Science is a broad term that encompasses a variety of subjects and techniques, such as statistics and artificial intelligence, that are used to analyze data and draw meaningful conclusions.

Let us explore the importance of machine learning in data science for data analysis and the extraction of important insights from data.

What is Machine Learning ?

Machine learning is a technique of data analysis that uses artificial intelligence to create analytical models. ML is a branch of AI that functions based on the integral conception of computers having the caliber of learning from data, identifying patterns, and making decisions without having the need for human input.

To get you started, below are a few examples of machine learning applications:

The much-hyped Google self-driving car applies machine learning at its most basic level.
Our daily life and machine learning application for instance online recommendations and offers from E-commerce or entertainment sites like Netflix
Business enhancement by observing consumer's feedback which entails the integration of machine learning with developing linguistic rules.

What is Machine Learning in Data Science?

To understand the importance of machine learning in data science, let us delve into the critical roles that Machine learning performs in Data science.

Data science entails going through a glut of data, and massive quantities of data are automatically analyzed by Machine Learning. Machine Learning effectively optimizes the data analysis process and gives real-time data-driven predictions without requiring human intervention. To make real-time predictions, a Data Model is constructed and trained automatically.

Let us consider the vital machine learning steps involved in Data Science;

Data Collection: Data collection is regarded as the first step in Machine Learning. Collecting relevant and trustworthy data is critical since the quality and quantity of data have a direct impact on the outcome of your Machine Learning Model. This dataset is also utilized to train your data model, as mentioned before.

Data Preparation: The first phase in the whole Data Preparation process is Data Cleaning. This is a crucial step in preparing the data for analysis. Data preparation guarantees that the dataset is free of errors and corruption. It also entails converting the data to a standardized format. The dataset is also divided into two portions, one for training your data model and the other for evaluating the Trained Model's performance.

Model's Training: This is where the "learning" begins. The output value is predicted using the Training dataset. In the first iteration, this output is bound to deviate from the required value. Practice, on the other hand, makes a Machine perfect. After making certain tweaks to the startup, the step is repeated. The Training data is utilized to increase your Model's prediction accuracy over time.

Model Evaluation: Now that you've finished training your model, it's time to assess how well it performed. The dataset that was set aside during the Data Preparation procedure is used in the evaluation process. This information was never utilized to train the model. As a result, testing your Data Model against a fresh dataset will give you a sense of how it will perform in real-world scenarios.

Prediction: Just because your Model has been trained and assessed doesn't mean it's perfect and ready to use. The parameters can be tweaked to improve the model even more. Machine Learning culminates in prediction. This is the point at which your Data Model is deployed and the Machine uses its learning to respond to your question.

To have a more in-depth comprehension of the relationship between Machine Learning and data science, it is imperative to learn more about machine learning key algorithms involved in data science. Let us explore them in brief:

Datasets are categorized into three problems wherein machine learning algorithms perform their tasks

Regression: Regression is utilized when the output variable is in continuous space. Curve-Fitting Techniques are probably something you've come across in mathematics. Does the phrase "y=mx+c" ring a bell? The same principles are used in the regression. Finding the equation of a curve that fits the data points is more like regression, and once you know the equation, you can anticipate the output values accordingly. Linear Regression, Perceptron, and Neural Networks are some well-known Regression Algorithms. Regression is important for financial forecastings, such as stock market forecasting and home price forecasting.

Classification: Classification is employed when the output variables are discrete values. It's a Classification challenge if you're trying to figure out which group your data belongs in. Classification algorithms examine current data to assist in predicting the Class or Category of new data. Finding curves that split data points into different Classes/Categories is more like classification. Classification is difficult when it comes to labeling an email as spam. Gmail, for example, will scan any email for the characteristics that characterize spam and begin putting it in your Spam Folder if 80 percent or more of the characteristics match. Support Vector Machines, Neural Networks, Naive Bayes, Logistic Regression, and the K Nearest Neighbour are some well-known Classification Algorithms.

Clustering: It's a Clustering challenge if you only wish to group data points with similar features without labeling. Similar data points should, in theory, be grouped together in the same Cluster depending on multiple definitions of similarity. Different Clusters should have as many points as feasible that are dissimilar. Clustering algorithms look for patterns in a dataset without assigning labels to them. K-Means Clustering and Agglomerative Clustering are two well-known clustering algorithms. Customers' purchasing habits are clustered using this algorithm. The Supervised Learning Model of Machine Learning includes regression and classification, while the Unsupervised Learning Model includes clustering.

Why Machine Learning is Important for Data Scientists

Machine learning and data science hence are two sides of the same coin. Without which data science operations are unachievable. In the coming future, process automation will replace the majority of human labor in manufacturing. To match human abilities, devices must be intelligent, and Machine Learning lies at the heart of AI. For accurate forecasts and estimations, Data Scientists must grasp Machine Learning. This can let machines create better decisions and take better actions in real-time without requiring human participation.

Machine learning is revolutionizing data mining and interpretation. More accurate automatic sets of generic algorithms have supplanted traditional statistical processes. As a result, Machine Learning skills form a pivotal aspect for data scientists.
