Machine Learning and its Role in Data Science

Imagine walking into your food delivery app and it just knows the delicacy you are in the mood to eat! Or YouTube suggests precisely what you’ve been searching for. Feel like this is magic? For everyone else, it may be. But for someone like you, interested in machine learning training in Pune, it isn’t. It is machine learning (ML) at work! Machine learning, popularly known as ML, may sound a little complicated. But don’t worry as we will explain it with some easy examples in this blog. Besides, since it is fundamental to data science, we will also understand its role. What is Machine Learning – Beginning from the Basics! In simple language, ML is a way of teaching computers how to learn from data without explicitly programming them for every task. So, instead of providing step-by-step instructions, you give the machine examples and allow it to find patterns. Imagine you are a teacher, teaching students about cars. Instead of saying a car has four wheels, four doors, one roof, etc., you show them multiple pictures of cars. Eventually, the children get it. This is precisely how ML works. It learns from examples. Types of machine learning include; Supervised Learning: The machine receives labeled data (for example, animals with names) and it learns to predict the labels. Unsupervised Learning: This involves only raw data (without labels) and the machine finds hidden patterns or groups. Reinforcement Learning: The machine tries, errs, and learns. What is Data Science – Let’s Also Understand This! Data science refers to deriving meaningful insights from structured and unstructured data.  It combines various fields like computer science, domain knowledge, and statistics to transform data into usable information. The process involves collecting data, cleaning it, analyzing it, visualizing it, and making informed predictions based on what the data says. For example, data science helps retail companies analyze consumer shopping habits, understand what they want, and make suggestions that align with their needs. While contributing to quicker decision-making, it also helps enhance and expedite sales. How Does ML Contribute to Data Science? Let’s not get into the technicalities as of now as you will do that during your machine learning training in Pune. We’ll stick to simple examples for an easier understanding. ML is a data scientist’s tool. Thus, if data science is the engine, ML turbocharges it, enabling data scientists to develop predictive models, uncover insights, and automate the overall decision-making process for companies. Another way of understanding it is thinking of data science as a journey of uncovering a treasure and valuable insights from a massive mountain of data. You must work like a detective, sifting across clues to solve the mystery. ML works as your tool. It serves as a smart engine that learns from the clues, helping you make forecasts and decisions. Let’s look at some simple, yet real-world examples to enhance your understanding. Spam Detection: Ever thought how your inbox categorizes your emails into spam and legitimate, relieving you from the tedious process of sorting them manually? The answer is ML algorithms, trained on vast amounts of emails, labeled as spam or not spam. Here, they learn to identify patterns, including sender addresses, specific keywords, or email structure – characteristics of a spam email. So, when you receive a new email, the algorithm analyzes it based on the patterns learned and decides an email’s category. Weather Forecasts: The mechanism of weather predictions is a little complicated. However, it involves ML at the backend. The algorithms receive data like historical weather data, including wind, temperature, speed, etc. They then learn the relationship between these factors and then make weather forecasts based on the data they have. Fraud Detection: Custodians of millions and billions of rupees, banks are also responsible for identifying and flagging suspicious transactions. This is possible with ML that discovers unusual patterns, for example, a sudden purchase in a foreign country, and flags it red. Why Does Data Science Love ML? It is because ML and its algorithms are capable of doing many things. Some include; Processing and learning from massive datasets – something beyond human abilities to do manually Uncovering subtle relationships and insights within data, otherwise difficult for the human eye to identify and process After training, ML models can predict based on new and unseen data or automate various decision-making processes They continuously improve with exposure to data, refining their understanding and improving accuracy over a period Prepared to Take Up Machine Learning Training in Pune? We hope the above helped you enhance your understanding of ML’s role in data science. Given the importance of data in the contemporary environment and the role ML plays in data science, a career as an ML professional can unlock several remunerative opportunities for you.

Machine learning and data analytics are two such transformative technologies. They are helping businesses use data better and drive more favorable outcomes. For example, machine learning involves analyzing and interpreting to drive more meaningful insights from a dataset. On the other hand, data analytics help process substantial datasets efficiently. Of course, both these technologies excel as individual contributors. However, blending them can drive more value for businesses. How? While businesses should know this, it can also benefit you as someone looking to join machine learning classes in Pune or pursue data analysis courses in Pune. It will help enhance your knowledge and understanding of the role these technologies play when combined. What is Machine Learning? Data is critical to every business. It is a priceless asset businesses rely upon to make decisions, understand the macro and micro environment, comprehend their customers better, and more. Now what does machine learning do here? It is a subset of AI that helps businesses analyze massive datasets, calculate risk factors, and predict outcomes. It uses historical data to make forecasts and derive output values. No wonder, millions of companies worldwide use ML for diverse applications and benefit from it significantly.  What Do You Mean by Data Analytics? On the other hand, data analytics involves examining large datasets to unearth various patterns, trends, and insights. It involves applying statistical and data mining techniques, along with ML algorithms to extract valuable information from the data. Consequently, data analytics helps companies identify opportunities, mitigate risks, make informed decisions, and optimize their business processes.  The Role of Machine Learning in Data Analytics Data analytics and data science involve analyzing raw data and drawing meaningful insights. However, ML’s role extends to enabling companies to use advanced algorithms to automate data analysis and make real-time forecasts without human intervention. However, discover more about data analytics and ML collaboration and precisely, the role of ML in data analytics. 5 Stages Explaining ML’s Role in Data Analytics ML and data analytics collaborate in a very organized manner that helps businesses reach a particular outcome. The steps include the following. Step 1: Data Collection Machine learning helps collect and analyze structured, unstructured, and semi-structured data from various databases in various forms. Step 2: Cleanse and Prepare Data Data preparation involves ML helping businesses analyze the data and prepare features associated with the business problem. Once it does that, the next step involves cleansing it to free it from inconsistencies and elements that may ruin the data’s quality and erode the decision-maker’s understanding of it. Step 3: Model Training Model training relies on the quality of the training data and the ML algorithm you choose, which you do per user needs. In addition, you should consider model algorithm performance, complexity, interpretability, etc., for higher model accuracy. Once you choose the correct ML algorithm, you divide your training sets into training and testing to determine the ML model’s variance and bias. The outcome of model training is a working model you can validate, test, and deploy. Step 4: Model Evaluation and Retrain Once you finish training your model, you can evaluate it via different metrics. To do so, choose a metric that relies on the model type and implementation plan. Although you can train and assess your model, you shouldn’t expect it to solve your problems. You can improve it further by fine-tuning the parameters to achieve better accuracy. Step 5: Prediction This is the final stage and the purpose of all of the above. However, when you talk about model prediction, you should also look at prediction errors. Understanding these errors will help you develop more accurate models. Besides, you can minimize prediction errors by balancing bias and variance. The above can help businesses use data better and make more informed and favorable decisions. Applications of ML and Data Analytics in Different Industries Let’s look at a few industries where ML and data analytics collaborate to foster the industry’s growth. Retail Retail is one of the largest data-driven businesses in the world. That’s because every retailer generates zillions of bytes of data every day, concerning customer preferences, sales, purchases, orders, etc., in a structured, semi-structured and unstructured form. Of course, it is practically impossible to glean insights from such massive volumes of data. Together ML and data analytics play a role here. While data analytics collects, cleanses and processes the data, ML helps retailers derive useful insights related to trends, buying patterns, seasonal sales variations, demand spikes, and more. All these insights can form the basis of planning, prediction and decision-making and serving customers better. Healthcare Even when it comes to healthcare, service providers who deal with thousands of patients every day and generate extensive volumes of data. These include patient information, prescriptions, appointment information, follow up information, diagnostic reports, surgical requirements, patient history, administrative data, billing and invoicing, insurance claims and so much more.  Data analytics and ML can prove useful in each of these areas. For instance, when it comes to diagnostic data, while data analytics can work on the data part and make it usable with its abilities, ML can further analyze the diagnostic reports, and identify anomalies or malign cells. These ML reports can support doctor reviews and enable more informed decision-making. Oil and Gas The oil and gas industry isn’t an exception to the collaborative use of ML and data analytics.
