Building Blocks of ML Algorithms

Machine learning is basically about the science of giving computers the ability to learn and it is being used daily in our lives through various significant applications such as self-driving cars, speech recognition, searches, and recommendations. And let us tell you a fact. Machine learning is one of the most significant tech trends. It seems that AL and ML algorithms are presently being used in as many kinds of software applications as possible.

The fundamental building blocks of machine learning algorithms, machine learning techniques are built to work and learn from data, create and test algorithms to create accurate models.

DATA + CREATE & TEST ALGORITHMS = Accurate Models 

Machine Learning is giving input to the ML algorithm which trains itself and then gives the desired output. It’s similar to training giving the test and get results. 

Following are basic Building Blocks of machine learning algorithm to work

Data

Data is everything and Everything is data. Machine Learning and AI is totally nothing without data. For the last few years, whole ML work is based upon a data-driven approach. when scientists began creating programs for computers to analyze large data and draw conclusions or learn from the results. In ML, data is used to train the algorithm. Data is used for both training the algorithm and also for testing purposes. Data is the most important part of Machine Learning, without data no model can be trained and it won’t give us the potential results.

Data annotation is the process of labeling the data recognizable to machines through computer vision or natural language processing (NLP) based AI or ML training available in various formats like text, videos, and images.

Model

The second most significant building block of Machine learning is Model because the trained Data sets is fed on the model, which is usually a particular algorithm. ML model refers to the model artifact that is created by the training process. The learning algorithm finds patterns in the training data sets that map the input data attributes to the target and it outputs an ML model that captures these patterns.

Objective Function

The third step of ML is when the model is trained on the data, It has to be compared and analyze how close it is to reality. This is when the objective function comes into the picture. The objective function is a measure of how close the output of the model is from the target.

Under objective function “objective” used in the sense of a goal. This function, taking data and model parameters as arguments, can be evaluated to return a number and check the process. 

Optimization Algorithm

The next step after objective function checks how far from the target the trained model is, we have to make all corrections in the algorithm to have maximum accuracy or optimization. The optimization algorithm uses the values of the objective function and varies the parameters of the model. This process is repeated until we have the values of the parameter for which the objective function is optimal. One of the most common optimization algorithms is gradient descent which is used extensively in the field of machine learning to find a local minimum.

Machine learning takes lots of practice to learn from mistakes and before it can become accurate and perfect into doing a task right. Like human beings Machines also need a lot of practice to reach perfection. Training data sets by humans help machine learning to become perfect after a lot of corrections and trials, it reaches the stage where it needs to be.

WHY MACHINE LEARNING NEEDS DATA ANNOTATION?

Machine learning needs proper datasets and model machines to learn much accurately to assist humans to achieve their goal and this is what machine learning is used for. Data annotation is done to create the training data sets for ML. Data annotation helps machines to learn certain patterns and correlate the results, and then use the data sets to recognize the similar patterns in the future to predict the results.
