This article explores the intricacies of developing machine learning applications and emphasizes the structured approach necessary for success.
With a step-by-step approach, this article will showcase the “Types of Machine Learning Algorithms” based on their main classification. By means of this classification, it becomes easier to understand the utility of an algorithm along with its benefits and potential
Here we go, with our Machine Learning Algorithm Types-
Types of Machine Learning Algorithms
Machine learning algorithms fall into three main categories:
1. Supervised Machine Learning:
– Ideal for tasks such as categorical classification, activity monitoring, and predicting numerical values.
– Empowers businesses to make accurate predictions based on labeled historical data.
2. Unsupervised Machine Learning:
– Utilized for grouping or clustering, dimensionality reduction, and anomaly detection.
– Unleashes the potential to uncover hidden patterns within unlabeled data.
3. Reinforcement Machine Learning:
– Limited in machine learning business applications but holds promise for path optimization in the transit industry.
– Undergoing extensive research, reinforcement learning is poised to evolve and complement machine learning application development.
After a brief overview of the types of algorithms involved in machine learning, here is an elaborate take on how the actual development takes place. With a deeper dive into Developing Machine Applications in a step-by-step structured manner, this approach will empower the understanding in an organized style.
Developing Machine Learning Applications: A Structured Approach
1. Problem Framing:
Problem framing is the first step and involves framing a machine learning problem regarding what we want to predict, and the observation data required to make those predictions. Predictions are generally a label or a target answer; they may be a yes/no label (binary classification) or a category (multiclass classification), or a real number (regression)
– Just like any process in the world of developing a solution, the foundational step involves defining the machine learning problem, specifying what needs prediction, and identifying the observational data required.
– Predictions may range from binary or multiclass classification to regression
2. Collecting and Cleaning Data:
After framing the problem and identifying what kind of historical data the business has for prediction modeling, the next step is collecting the data. This can be from a historical database open datasets, or any other data sources. This step is crucial as the quality and quantity of data gathered will directly determine how good the predictive model will be. The data collected is then tabulated and called Training Data.
– Once the problem is framed, the subsequent step involves collecting historical data from databases, open datasets, or other sources.
– Accuracy of data plays a vital role in the process. This is why, ensuring the quality and quantity of data is crucial for effective machine learning application development.
3. Data Preparation:
Not all the collected data is valid for a machine learning application. Thus, the next step is to clean the irrelevant data, which may affect the accuracy of prediction or take additional computation without aiding in the result. The data is loaded into a suitable place and then prepared for use in machine learning training. Here, the information is put all together, and then the order is randomized as the order of data should not affect what is learned. This is also a good enough time to do any visualizations of the data, as that will help you see if there are any relevant relationships between the different variables, how you can take their advantage, and show you if there are any data imbalances present. Also, the data now has to be split into two parts. The first part used in training our model will be the majority of the dataset, and the second will be used to evaluate the trained model’s performance. The other forms of adjusting and manipulation like normalization, error correction, and more occur at this step.
– After collecting and cleaning data, the next step involves cleaning irrelevant data, randomizing the order, and visualizing relationships between variables
– Splitting data into training and evaluation sets for model training and performance evaluation.
4. Feature Engineering:
Sometimes raw data may not reveal all the facts about the targeted label. Feature engineering is a technique to create additional features by combining two or more existing elements with an arithmetic operation that is more relevant and sensible. For example: In a computer engine, it is common for RAM and CPU usage to reach 95%, but something is messy when RAM usage is at 5%, and CPU is at 93%. In this case, a ratio of RAM to CPU usage can be used as a new feature, which may provide a better prediction. If we are using deep learning, it will automatically build features itself; we do not need explicit feature engineering.
– Enhances the understanding of data by creating additional features through relevant arithmetic operations.
– Essential for extracting nuanced insights not apparent in raw data
5. Training a Model:
The data is first to split into training and evaluation sets to monitor how well a model generalizes to unseen data. This lets the algorithm read and learn the pattern and helps it map between the feature and the label. The learning can be linear or non-linear, depending on the activation function and algorithm. A few hyperparameters affect the teaching and training time, such as learning rate, regularization, batch size, number of passes (epoch), optimization algorithm, and more.
– Data is split into training and evaluation sets to enable the algorithm to learn patterns.
– Learning can be linear or non-linear, influenced by hyperparameters such as learning rate, regularization, and optimization algorithm.
6. Evaluating and Improving Model Accuracy:
Accuracy is a measure of how good or bad a model is doing on an unseen validation set. Depending on the application, the model can use different accuracy metrics. E.g., for classification, we may use precision and recall or F1 Score; for object detection, we may use IoU (interaction over union). If a model is not doing well, we may classify the problem in either of the classes:
a) Over-fitting – When a model is doing well on the training data but not on the validation data. Somehow the model is not generalizing well. The problem includes regularizing the algorithm, decreasing input features, eliminating the redundant element, and using resampling techniques like k-fold cross-validation.
b) Under-fitting – In the under-fitting scenario, a model does poorly on both training and validation datasets. The solution to this may include training with more data, evaluating different algorithms or architectures, using more passes, and experimenting with learning rates, or optimization algorithms.
– Accurate model evaluation is crucial, with metrics tailored to the specific application (e.g., precision, recall, F1 Score).
– Addressing over-fitting and under-fitting scenarios through regularization, feature reduction, or additional training.
7. Parameter Tuning:
Once the evaluation is over, any further improvement in your training can be possible by tuning the parameters. There were a few parameters that were implicitly assumed when the training was done. Another parameter included is the learning rate that defines how far the line is shifted during each step, based on the information from the previous training step. These values all play a role in the accuracy of the training model and how long the training will take.For more complex models, initial conditions play a significant role in determining the outcome of training. Differences can be seen depending on whether a model starts off training with values initialized to zeroes versus some distribution of values, leading to the question of which distribution is to be used. Since there are many considerations at this training phase, you must define what makes a model suitable. These parameters are referred to as Hyperparameters. The adjustment or tuning of these parameters depends on the dataset, model, and training process. Once you are done with these parameters and are satisfied, you can move on to the last step. After iterative training, the algorithm will learn a model to represent those labels from input data, and this model can be used to predict the unseen data. The model is then deployed for the prediction on real-world data to derive the results.
– Fine-tuning parameters post-evaluation for improved model performance.
– Hyperparameters play a pivotal role in determining the accuracy and efficiency of machine learning application development.
