We have covered details about machine learning and its types to assist you more precisely in leveraging machine learning tools. Online machine learning tools and techniques, with model training basics, have also been covered comprehensively.

What is Machine Learning? 

Machine Learning (ML) is a sub-domain of AI that makes computers competent to learn from experiences like humans. It uses data, statistical methods, algorithms, and ML tools to analyze, develop models, and deduce accurate predictions (patterns, trends, etc.).

The core of AI lies in Machine Learning as it incorporates deep learning tools and neural networks to accelerate the ongoing advancements in Industry 4.0 and IoT.

 Machine Learning vs. Deep Learning: Know how they are similar and different 

ML works on various algorithms that use mathematical and logical programs to forecast outcomes from the data set. These ML algorithms operate in three segments –

  • Decision – Classifies labeled and unlabeled data to estimate the trend/pattern.
  • Error Evaluation – Runs an error function to assess the model accuracy
  • Model Optimization – Mitigates the differences to generate precise outcomes.

Here are some of the most common machine learning algorithm example for aspirants – 

  • Support Vector Machine (SVM)
  • K-Nearest Neighbors (KNN)
  • K-Means
  • Naive Bayes
  • Decision Tree
  • Linear Regression
  • Logistic Regression
  • Random Forest 
  • Dimensionality Reduction 
  • Gradient Boosting 
  • AdaBoost

Types of Machine Learning

Undoubtedly, ML becomes quite complicated when dealing with diverse data sets. 

Therefore, based on a particular goal, action, and result (in terms of data prediction), ML algorithms are classified into broadly four types –

1. Supervised Machine Learning

In Supervised Machine Learning, the data scientists train the model using labeled or known data sets. 

Here, the label or known data means the input data is already mapped with the correct output data. When the input data undergo a supervised machine learning algorithm, it maps the fed input with the correct output.

Based on this direct execution, the algorithm determines the patterns and trends in data, learns from past-record observations, and makes predictions.

The data scientist corrects these predictions by making suitable adjustments and further executes the cross-validation process. The loop continues until the model delivers the outcome with high precision.

Machine learning algorithm example includes SVM, KNN, Decision Trees, Naive Bayes, Neural Networks, Random Forest, Regression – Linear, Logistic, Polynomial, Forecasting, etc.

2. Unsupervised Machine Learning

It is just the opposite of supervised learning. In Unsupervised Machine Learning, the data scientists train the model using unlabeled or unknown data sets.

Here, the input data is not mapped with the correct output data. Instead, the input data undergo an unsupervised machine learning algorithm, which determines the fed input’s hidden patterns, trends, and insights (without supervision).

Further, the algorithm applies the clustering process to group the data sets based on their similarities and differences. And the dimension reduction process to reduce the number of attributes. 

After that, the model segments the data to study them in-depth. 

It includes Principal Component Analysis (PCA), Singular Value Decomposition (SVD), Partial Least Squares, Fuzzy means, Apriori, Hierarchical, Probabilistic, and K-Means Clustering.

3. Semi-supervised Machine Learning

Semi-supervised Machine Learning is simply the amalgamation of both Supervised and Unsupervised Machine Learning. The model uses the small labeled data sets with sizable unlabeled data sets to determine the unknown data sets and label them.

  • Classifies the data sets using Supervised ML algorithms. 
  • Extracts similar/distinct features using Unsupervised ML algorithms.

Further, the model utilizes the final data set as new input data to determine insights for making accurate predictions.

4. Reinforcement Machine Learning

Reinforcement Machine Learning is a trial-and-error-based behavioral ML process, more disciplined and feedback oriented. The data scientists train the model by reinforcing successful outcomes (set of final values, parameters, and actions). 

The main goal is to develop the best and optimal framework. Like Supervised ML, it also –

  • Learns from past-record experiences and observations
  • Examines all potential alternatives
  • Supervises and evaluates each prediction with high precision

Reinforcement ML includes three primary elements –

  1. Agent – Decision-maker
  2. Environment – Every single thing with which the agent interacts 
  3. Action – The process in execution by the agent and the deliverables.

1. Classify the problem in the first place – 

Study what type of data you have in the problem and classify it based on the  – 

  • Input Data – Whether the given data set is Supervised, Unsupervised, Semi-supervised, or Reinforcement Machine Learning Type.
  • Output Data – Whether the model’s deliverable is a regression (numbers), classification (feature extraction), or clustering (data grouping) type. 

2. Thoroughly study your data – 

For selecting the best machine learning tools, understand the data in depth, covering all aspects. It is the most underrated yet crucial prerequisite.

You must encompass the below 3-stage framework to dissect end-to-end –

  • Use statistical, numerical, and visualization methods to analyze the data.
  • From pre-processing to profiling and cleaning, entirely process the data.
  • Apply feature engineering to simplify data transformations. Also, enhance the performance and precision of the ML model. 

3. Discover the suitable ML algorithm – 

Abstract the key insights from the above two research points and choose the appropriate algorithm considering the following selection criterion –  

  • How long will it take to develop, train, test, and deploy the model?
  • How long will it take to deduce accurate predictions using the model?
  • How will it work on the precision of the model?
  • How will it evaluate the interpretability of the model?
  • Whether the model will be scalable enough to accommodate changes?

4. Apply ML algorithms and conduct A/B testing

Clearly define the evaluation criteria, create a Machine Learning Pipeline, and apply the algorithms to it. The ML Pipeline must monitor and compare the performance of every algorithm on the data sets. 

You can also A/B test the algorithm(s) on different dataset subgroups. To yield the optimum solution, execute this process periodically, significantly when new data adds to the model.

5. Conduct Hyperparameter Tuning or Optimization

Hyperparameter Tuning allows you to amplify the model’s performance. You can use it to reduce a predefined loss function and generate higher results with minimal errors. 

It is vital for controlling the ML model’s behavior. Therefore, conduct it regularly, or the model will generate less optimal results. 

Manual Search, Random Search, Grid Search, Bayesian Optimization, Tree-structured Parzen estimators (TPE), Halving Search (Grid and Randomized types), and HyperOpt-Sklearn are the top techniques.

Machine Learning Model Training

Machine Learning Model Training incorporates a comprehensive operation. In this, the ML algorithm learns from the proposed problem provided with the training data.

What is Model Training? 

Model training is an essential step in the development process for machine learning algorithms. Data scientists use various tools to find an algorithm’s best weights and biases to minimize its loss function over the prediction range. Loss functions are used to optimize machine learning algorithms. The types of loss functions used by data scientists can vary depending on the objectives they are trying to achieve and what kind or type of algorithm is being run.

The supervised and unsupervised learning techniques use mathematical representations to create relationships between data features and target labels. Being an essential step in machine learning, model training helps data scientists develop a working model that can be validated, tested, and deployed.
