What is Machine learning Life cycle?
Machine learning has given computers the ability to learn on
their own without having to be explicitly programmed. However,
how does a machine learning system function? As a result, the
machine learning life cycle can be used to explain it. A
machine learning project's life cycle is a cyclic method for
developing an effective machine learning project. The life
cycle's primary goal is to find a solution to the problem or
There are seven important steps in the machine learning life cycle, which are listed below:
- Gathering Data
- Data preparation
- Data Wrangling
- Analyse Data
- Train the model
- Test the model
Understanding the problem and knowing the problem's purpose
are the most critical aspects of the entire process. As a
result, before beginning the life cycle, we must first
comprehend the problem, as a positive outcome is contingent on
a thorough comprehension of the situation.
To address an issue, we develop a machine learning system called a "model" in the complete life cycle process, and this model is built by providing "training." However, we need data to train a model, therefore the life cycle begins with data collection.
1. What is Gathering Data?
The first phase in the machine learning life cycle is data
collection. This step's purpose is to identify and collect all
We must first identify the numerous data sources, as data can be obtained from a variety of places, including files, databases, the internet, and mobile devices. One of the most crucial stages in the life cycle. The output's efficiency will be determined by the quantity and quality of the data collected. The more data there is, the more accurate the prediction will be.
The following tasks are included in this step:
- Identify various data sources
- Collect data
- Integrate the data obtained from different sources
We obtain a cohesive set of data, also known as a dataset, by completing the aforementioned task. It will be used in the following steps.
2. What is Data preparation?
We must prepare the data for further processing after it has
been collected. Data preparation entails putting our data in
an appropriate location and preparing it for use in machine
In this step, we combine all of the data and then randomize the order of the data. This step can be further broken down into two steps:
- Data exploration: It is utilized to figure out what kind of data we're dealing with. We must comprehend data's features, format, and quality. An effective outcome is the result of a greater knowledge of data. Correlations, general patterns, and outliers can all be found here.
- Pre-processing of data:The next step is to prepare the data for analysis.
3. What is Data Wrangling?
Cleaning and turning raw data into a usable format is referred
to as data wrangling. It is the process of cleaning the data,
picking the variable to utilize, and changing the data into a
suitable format for further analysis. It's one of the most
crucial parts of the entire procedure. To overcome the quality
concerns, data cleaning is required.
It is not required that the data we have gathered be of constant use to us; part of the data may be useless. Data acquired in real-world applications may have a variety of problems, including:
- Missing Values
- Duplicate data
- Invalid data
As a result, we clean the data using a variety of filtering
The aforesaid concerns must be identified and resolved because they can have a detrimental impact on the quality of the final product.
4. What is Data Analysis?
Now the cleaned and prepared data is passed on to the analysis
step. This step involves:
- Selection of analytical techniques
- Building models
- Review the result
The goal of this step is to create a machine learning model
that will study the data using a variety of analytical
approaches and then evaluate the results. It begins with the
identification of the problem type, followed by the selection
of machine learning techniques such as
classification, regression, cluster analysis,
and so on, followed by the construction of the model using
prepared data, and finally the evaluation of the model.
As a result, in this stage, we take the data and build the model using machine learning algorithms.
5. What is Train Model?
The following stage is to train the model, in which we
increase our model's performance in order to achieve a better
solution to the problem.
Datasets are used to train the model, which is then used to train the model using various machine learning techniques. A model must be trained in order for it to comprehend the numerous patterns, rules, and features.
6. What is Test Model?
We test our machine learning model once it has been trained on
a specific dataset. We check the correctness of our model in
this stage by feeding it a test dataset.
The percentage correctness of the model is determined by testing it against the project or problem's requirements.
7. What is Deployment?
The final phase in the machine learning life cycle is
deployment, which involves putting the model into action in a
We deploy the model in the real system if the above-prepared model produces an accurate output that meets our requirements at a reasonable pace. However, before launching the project, we'll see if it improves performance by utilizing accessible data. The deployment step is equivalent to completing a project's final report.
