Hidden Markov Models (HMM)

One of these best practices is regularization, which helps with overfitting by shrinking parameters (e.g., weights) until they make less impact on predictions. As we’ve explored, no-code AI allows anyone to create and deploy machine learning models on their own, without needing programming skills. However, to become truly AI-driven, getting AI to work for you is not a one-time upgrade. It is a journey that will require an understanding of data management and the use of machine learning.

These ML algorithms which we will use are listed below and detailed in the following section. The R Statistical Programming Language is an open-source tool for statistics and programming which was developed as an extension of the S language. R is supported by a large community of active users and hosts several excellent packages for ML which are both flexible and easy to use. R is a computationally efficient language which is readily comprehensible without special training in computer science. The R language is similar to many other statistical programming languages, including MATLAB, SAS, … Read More

Hidden Markov Models for Speech Recognition

Data mining applies methods from many different areas to identify previously unknown patterns from data. This can include statistical algorithms, machine learning, text analytics, time series analysis and other areas of analytics. Data mining also includes the study and practice of data storage and data manipulation. Natural language processing is a field of machine learning in which machines learn to understand natural language as spoken and written by humans, instead of the data and numbers normally used to program computers. This allows machines to recognize language, understand it, and respond to it, as well as create new text and translate between languages. Natural language processing enables familiar technology like chatbots and digital assistants like Siri or Alexa.

Machine learning

Through the use of feature expansion, you will extend the capabilities of linear classifiers to find non-linear classification boundaries. Finally, you will employ kernel machines to train algorithms that can learn in infinite dimensional feature spaces. In a broad sense, artificial intelligence attempts to simulate human thinking and behavior. Machine learning specifically relates to systems that learn about conditions through data without a human interface and then apply the data to decision-making and other events, such as automation. A Random Forest model incorporates … Read More

Gaussian Mixture Models (GMM)

In the business world, decision trees are often used to develop insights and predictions about downsizing or expanding, changing a pricing model or succession planning. The performance of a machine learning model is primarily dependent on the predictive accuracy of its training dataset with respect to the outcome of interest. If you were able to know everything about a system (quantum physics aside) you would be able to perfectly predict its future state. In reality most datasets contain a small subset of information about a system – but that is often more than enough to build a valuable ML model. That said, adding in additional data can often help improve predictive performance.

Machine learning

Popular techniques include self-organizing maps, nearest-neighbor mapping, k-means clustering and singular value decomposition. These algorithms are also used to segment text topics, recommend items and identify data outliers. Analyzing data to identify patterns and trends is key to the transportation industry, which relies on making routes more efficient and predicting potential problems to increase profitability. The data analysis and modeling aspects of machine learning are important tools to delivery companies, public transportation and other transportation organizations. When choosing between machine learning and deep learning, consider whether you have … Read More

Credit Scoring Models with Machine Learning

Reinforcement machine learning is a machine learning model that is similar to supervised learning, but the algorithm isn’t trained using sample data. A sequence of successful outcomes will be reinforced to develop the best recommendation or policy for a given problem. Deep learning and neural networks are credited with accelerating progress in areas such as computer vision, natural language processing, and speech recognition.

Machine learning

Frank Rosenblatt creates the first neural network for computers, known as the perceptron. This invention enables computers to reproduce human ways of thinking, forming original ideas on their own. Alan Turing jumpstarts the debate around whether computers possess artificial intelligence in what is known today as the Turing Test. The test consists of three terminals — a computer-operated one and two human-operated ones. The goal is for the computer to trick a human interviewer into thinking it is also human by mimicking human responses to questions.

Gaussian Mixture Models (GMM)

Fueled by the massive amount of research by companies, universities and governments around the globe, machine learning is a rapidly moving target. Breakthroughs in AI and ML seem to happen daily, rendering accepted practices obsolete almost as soon as they’re accepted. One thing that can be said with certainty about the future of machine learning is that it will continue to play a central role in the 21st century, transforming how work gets done and the way we live. Actions include cleaning and labeling the data; replacing incorrect or missing data; enhancing and augmenting data; reducing noise and removing ambiguity; anonymizing personal data; and splitting the data into training, test and validation sets. While a lot of public perception of artificial intelligence centers around job losses, this concern should probably be reframed. With every disruptive, new technology, we see that the market demand for specific job roles shifts.

Machine learning

Supervised learning algorithms can be further subdivided into regression and classification. In supervised tasks, we present the computer with a collection of labeled data points called a training set (for example a set of readouts from a system of train terminals and markers where they had delays in the last three months). … Read More
