The world has been evolved with the introduction of data science and machine learning. These two correlated chapters have transformed our vision of seeing and analyzing data. They have set a benchmark for future technical developments and various domains where this technology can be used. To collect, purify, and analyze the data is quite a hectic task. Then comes one of the most essential and difficult tasks, .e., training the model with the data as per our requirements. 

The algorithms that we use for machine learning give us output with high accuracy. These algorithms and the knowledge and skills behind the development of machine learning have made them versatile. It is used in almost all the sectors of business, and development. Whether it would health care, education, defense, or anything else, machine learning models aid in the progress of every field.

With the growth of technology, the requirements in different sectors are gradually increasing. The demands of stakeholders are becoming technology-oriented. The traditional machine learning approach is quite time-consuming, difficult, and requires in-depth knowledge of the subject. It demands high technology experience in the field. Hence, it is not possible to develop machine learning models every time. 

Then from all the struggles faced by the technical minds, there emerged a new and enhanced version of machine learning and it was termed AutoML or Automated Machine Learning. This requires an important role of data scientists. From the raw data, that we have got by data pre-processing, we can easily make a machine learning model. This makes the work easier, efficient, highly productive, and proficient.

The most important thing – model training is now fast, accurate, and efficiently done! Isn’t it amazing! In a traditional machine learning model, all the steps needed to be followed in proper sequential order but using AutoMl things have become fast. All the bulky task, that required hands and minds of the various data scientist is ow automated. 

The tasks like data collecting, data labeling, feature extraction from data, and training the model, everything is now automated. We no more require the continuous help of specialized data scientists for this work. This has made it possible to do work for months in a few days! This is the essential point added by automated machine learning. Now, we can prepare many models for professional and scientific purposes in a short period. 

The field of automated machine learning has helped in getting accurate insight and predictions. This results in high accuracy in forecasting and error resolution of the model. This helps in developing problem-solving capability and aids in the process of development.

Importance of Automated Machine Learning

It is well-known that with the introduction of new technologies, there comes the involvement of a new approach. Machine learning involves various steps and in each step, there is a different requirement. It requires high computation, and efficiency. For this, one requires various skills like mathematics, logical reasoning, computer skills, programming knowledge, subject knowledge, debugging, deployment knowledge, and much more.

With all these skills, the probability of the deployment of the final model is not 100%. This is because the actual functioning of all the steps depends on how well the model is integrated. After all, the input of one step is the output for the other. The other thing is accuracy and errors. The manual calculations and estimations are prone to errors. 

Hence, to increase efficiency, accuracy, and reduce errors, it is better to use computerized automated models. This is the feature provided by AutoML. The high computational work of data scientists, i.e., to collect and process the data according to the usage of the model, is now automated. This reduces time and cost. It eliminates the risk of errors also. This automation has helped in increasing the scope of machine learning.

The automated machine learning models can be used in almost all the fields like health care, banking, marketing, education, transport, agriculture, defense, and much more. The current models used during this technology have increased the rate of customer satisfaction.

The DataRobot is the base of this foundation. The use of machine learning and deep learning has enabled various features and provided a broad list of operations that can enhance the development of further models. Hence, by automation, it becomes easy to develop and deploy the machine learning models. This builds the leading step towards a successful and developed nation.

It involves – Classification, Regression, and Forecasting

The automated machine learning approach is used when we want to design a model that requires performing recursive operations. In that case, the traditional machine learning model is time-consuming and utilizes maximum resources. To avoid such resource and time wastage, the automated ML is the best approach.

It helps in building solutions without the requirement of in-depth knowledge of the particular subject or heavy coding practices. Hence, it not only provides an efficient way of problem-solving but also helps in the management of various other factors. For this, different companies have different models like Microsoft comes with Azure which serves this purpose.

Classification

Then comes the role of supervised learning. To use automation in machine learning, it is necessary to train the model so that it can work as a data scientist at the initial stage. This is required as the main work of a data scientist is now to be done by the machine. For this, the model needs to learn and understand the pattern. It involves neural networks and deep learning.

It creates categories based on some common features or functions. Hence, the sub-divisions of the model are created which help in the proper distribution of the main task. This can be done using Python as its libraries are quite useful. Here, the output value is categorical.

Regression

In this, the relation between two quantities is calculated to determine their dependencies. Here, the relation between numerical quantities is found. Then the data is sorted accordingly. This helps in establishing the relationship between the variable whose value depends on the other, i.e., independent variable. 

Regression with automated learning has boosted the process of data segregation, data cleaning, and grouping of data. It is of high importance as the numeric data is mostly found in the data set.

Forecasting

Forecasting is required in every field, whether it would be related to sales forecasting, business growth, increase in Covid patients in the coming months, weather forecasting, satellite forecasting, or anything else. This is one of the common and essential things that the model should be able to do efficiently and accurately.

The automated machine learning gives rise to the time-series forecasting technique. This also uses past or historic values for better output. It collects various variables and then classifies them. Hence, classification is used. Then it draws relationships between different parameters or variables. 

Sometimes, this technique requires the grouping of the data set. It takes the grouped values as input and then draws the relation between them. 

Microsoft Azure uses these three techniques, i.e., Classification, Regression, and Forecasting to solve the machine learning problem and design an automated solution for the same. 

There is another example for AutoMl, i.e., Google autoML. They offer autoML models with their highly advanced algorithms. They have used neural networks and the model performed simple tasks and now they have added videos and NLP functioning also. In this way, the field is increasing day by day.

In Python, we have an AutoML library, that makes functioning very easy. This library supports all the necessary features and functions that are required for building an automated machine learning model. It should be noted that data cleaning, feature selection, and parameters are the main task that needs to be handled during model formation. 

These complex algorithms include various parameters and require meta-learning, genetic programming, multi-arm bandits, Bayesian optimization, and much more. They require high run-time and various parameters. These parameters should be precise and related to the function for which they are required. This helps in the proper functioning of the libraries.

There are a few drawbacks of automated machine learning also. The algorithms require specific technologies that are still under development. The solutions require high checking and the model should be developed with proper use of library functions. 

The other thing is the time required to train the AutoML model. This highly depends on the computational power of the designed model. But the main advantage is that we can run the model on local machines also using Google Colab.

The automated machine learning model requires various domain knowledge – neural networks, transfer learning, deep learning, Auto-Keras, Auto-Sklearn, the Tree-based Pipeline Optimization Tool (TPOT), and much more.

With all this, the automated machine learning has revolutionized the whole industry. This brings an increase in the scope of further development. In this way, there is a wide scope of this technology in the future!
