What is ML?ML: Machine Learning |
What is Machine LearningML or Machine learning is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning (ML) is a type of artificial intelligence (AI) that allows software applications to become more accurate at predicting outcomes without being explicitly programmed to do so. Machine learning algorithms use historical data as input to predict new output values. |
| Machine Learning is the study of data-driven methods capable of mimicking, understanding and aiding human and biological information processing tasks. In this pursuit, many related issues arise such as how to compress data, interpret and process it. Often these methods are not necessarily directed to mimicking directly human processing but rather to enhance it, such as in predicting the stock market or retrieving information rapidly.
In this probability theory is key since inevitably our limited data and understanding of the problem forces us to address uncertainty. In the broadest sense, Machine Learning and related fields aim to ‘learn something useful’ about the environment within which the agent operates. Machine Learning is also closely allied with Artificial Intelligence, with Machine Learning placing more emphasis on using data to drive and adapt the model. In the early stages of Machine Learning and related areas, similar techniques were discovered in relatively isolated research communities. This can be unified treatment via graphical models, a marriage between graph and probability theory, facilitating the transference of Machine Learning concepts between different branches of the mathematical and computational sciences. |
Data ScienceData science uses scientific methods, processes, algorithms and systems to extract knowledge and insights from structured and unstructured data as one of the hottest professions in the market today |

Linear RegressionLinear Regression is a machine learning algorithm based on supervised learning. It performs a regression task. Regression models a target prediction value based on independent variables. It is mostly used for finding out the relationship between variables and forecasting. Different regression models differ based on – the kind of relationship between dependent and independent variables they are considering, and the number of independent variables getting used. |
| Exploratory Data Analysis: Performed initial investigations on data so as to discover patterns, to spot anomalies, to test hypothesis and to check assumptions with the help of summary statistics and graphical representations. |
| Data Visualization: Using data visualization, I summarized the data with graphs, pictures and maps, so that the human mind has an easier time processing and understanding the given data. Data visualization plays a significant role in the representation of both small and large data sets, but it is especially useful when we have large data sets, in which it is impossible to see all of our data, let alone process and understand it manually. |
| Training and Testing: In this project, datasets are split into two subsets. The first subset is known as the training data - it's a portion of our actual dataset that is fed into the machine learning model to discover and learn patterns. In this way, it trains our model. The other subset is known as the testing data. |
| Train and Evaluate Linear Regression: Simple linear regression is an approach for predicting a quantitative response using a single feature (or "predictor" or "input variable"). It takes the following form: y=β0+β1x |
| What is Machine Learning?
The term machine learning refers to the automated detection of meaningful patterns in data. In the past couple of decades it has become a common tool in almost any task that requires information extraction from large data sets. We are surrounded by a machine learning based technology: search engines learn how to bring us the best results (while placing profitable ads), anti-spam software learns to filter our email messages, and credit card transactions are secured by a software that learns how to detect frauds. Digital cameras learn to detect faces and intelligent personal assistance applications on smart-phones learn to recognize voice commands. Cars are equipped with accident prevention systems that are built using machine learning algorithms. Machine learning is also widely used in scientific applications such as bioinformatics, medicine, and astronomy. One common feature of all of these applications is that, in contrast to more traditional uses of computers, in these cases, due to the complexity of the patterns that need to be detected, a human programmer cannot provide an explicit, fine- detailed specification of how such tasks should be executed. Taking example from intelligent beings, many of our skills are acquired or refined through learning from our experience (rather than following explicit instructions given to us). Machine learning tools are concerned with endowing programs with the ability to “learn” and adapt |
Types of machine learningMachine learning and artificial intelligence are concepts to describe similar purposes under the data sciences. Machine learning definition a component included in the general concept of artificial intelligence. ML uses statistical methods to train algorithms and find patterns or insights that data, and use this to inform and take decisions. The main types of machine learning are:
SupervisedSupervised machine learning uses data to train algorithms and models that can be used to make predictions. The model predicts the outputs, based on the inputs and update this mapping adjusting the weights and bias until the final data is accurate. Some examples of use supervised machine learning are text classification, spam detection and recommendation systems based on the related behaviour of the user.
Unsupervised Unsupervised machine learning also uses algorithms to uncover hidden patterns in data classification and other tasks.
Reinforcement Reinforcement machine learning is another type of behavioral algorithm that learns in real time through the trial and error process. Can find better accuracy and can be trained for specific tasks.
