Machine learning (ML) and data science have distinct functions and goals. Machine learning is a set of methodologies that enables computer technology to learn from data, whereas data science is a strategy to extract insights from data.
However, there is a similarity between data science and machine learning. Both the fields employ arithmetic, statistics, and algorithms to derive value from data. If you want to pursue a career in data science or machine learning, then a certificate program in data science and machine learning will help you get a headstart in your career.
What is data science?
Data science deals with data to gain essential business insights. It is a multidisciplinary way of analysing vast volumes of data. The demand for data scientists has increased in today’s market.
What is machine learning?
Software programmes can predict outcomes more correctly with machine learning, a subset of artificial intelligence, without needing explicit instructions. ML algorithms come up with new output values through the previous data. Machine learning is vital because it helps create new things and provides businesses with a picture of trends in consumer behaviour. For many companies, machine learning has emerged as a necessary vital differentiation. An IIT Roorkee machine learning certification course will be perfect for you if you want to pursue a career in the field.
Role of machine learning in data science
Machine learning is implemented in data science in the following steps:
Step 1: Data collection
Data collection is the first step in machine learning. Notably, machine learning assists in gathering and analysing any kind of data (structured, unstructured or semi-structured) from any database throughout systems following the business challenge.
Step 2: Data preparation and cleansing
Data preparation uses various ML techniques for assessing the data and making features according to the business requirements. When defined correctly, ML systems comprehend the elements and connections between them.
Data in the real world is dirty and polluted with inconsistencies, partial information, noise, and missing values. Thus, you will have to clean the data after data preparation is finished.
Machine learning allows us to quickly and automatically identify missing data, do data imputation, encode category columns, and eliminate outliers, duplicate rows, and null values.
Step 3: Model training
The machine learning method's selection and the training data's calibre are essential components of model construction. The requirements of the end user are used to select ML algorithms.
You should also consider the model method's complexity, performance, interpretability, computer resource requirements, and speed if you want your models to be more accurate.
After selecting the best machine-learning technique, the training data set is divided into two halves for training and testing. This is done to determine the bias and variance of the ML model.
The model training procedure will produce a functional model that can be further evaluated, validated, and deployed.
Step 4: Model prediction
Understanding prediction mistakes is essential when discussing model prediction (bias and variance).
Having a solid understanding of these issues would make it simpler to construct accurate models and prevent the flaws of overfitting and underfitting the model.
To further reduce prediction errors, a good data science project should find the right balance between bias and variance.
