Understanding K-Nearest Neighbors

#artificialintelligence

Machine learning (ML) algorithms are often categorized as either supervised or unsupervised, and this broadly refers to whether the dataset being used is labelled or not. Supervised ML algorithms apply what has been learned in the past to new data by using labelled examples to predict future outcomes. Essentially, the correct answer is known for these types of problems and the estimated model's performance is judged based on whether or not the predicted output is correct. In contrast, unsupervised ML algorithms refer to those developed when the information used to train the model is neither classified nor labelled. These algorithms work by attempting to make sense out of data by extracting features and patterns that can be found within the sample.


Stolen Bike Visual Analysis using Tableau

#artificialintelligence

The dataset used here is for the stolen bikes in the United Kingdom from 2014 and 2017. It contains the column names such as "Crime ID", "Crime Type", "Falls within"(i.e the police station jurisdiction), "Last outcome category"(i.e the status of the case), and "Location".


Professionalization of Artificial Intelligence (AI)

#artificialintelligence

As organizations invest more in their AI and data capabilities, employees understand the growing influence of these technologies on their companies and careers. But despite their best efforts, many of these employees will not have the right training and qualifications to work effectively with AI. It's important for organizations to establish education and training requirements for their AI practitioners. Data scientists have varying qualifications, and not all have sufficient training in mathematics or computer science for AI projects. Even an employee with a Ph.D. might have studied a narrow field that isn't relevant to a particular company's needs.


How to detect plagiarism in the text using Python

#artificialintelligence

In this tutorial, we're going to learn how to Make a Plagiarism Detector in Python using machine learning techniques such as word2vec and cosine similarity in just a few lines of code. Once finished our plagiarism detector will be capable of loading a student's assignment from files and then compute the similarity to determine if students copied each other. To be able to follow through this tutorial you need to have scikit-learn installed on your machine. We all know that computers can only understand 0s and 1s, and for us to perform some computation on textual data we need a way to convert the text into numbers. The process of converting the textual data into an array of numbers is generally known as word embedding.


Can AI Change The Game For Retail In 2020?

#artificialintelligence

Artificial Intelligence (AI) is considered as the most promising technological advancement in the world of business. AI in retail promises benefits such as enhanced planning, higher scalability, and automated processes along with reduced errors. AI technology continues to transform with new systems that are designed and optimized for specific industries. The retail industry still has a long way to get benefitted from the new tool, mostly because AI software becomes expensive to purchase, integrate, and maintain. Lately, there are very few retail establishments that can justify the expense of integrating an AI system.


The Exponential Growth of AI in Brain Care and Treatment

#artificialintelligence

Advances in computer science are helping to accelerate a broad spectrum of scientific research. The more complex the problem, the greater the potential for artificial intelligence (AI) machine learning to help identify patterns and make predictions. How widely is machine learning being used in treating diseases and disorders of the brain? A new study published earlier this month in the science journal APL Bioengineering examines the state-of-the-art uses of AI for brain disease, and shows there has been exponential growth in over a decade. The biological brain has been the inspiration for artificial neural networks, a type of artificial intelligence (AI) machine learning model.


How Machine Learning will Transform Cybersecurity - BoTree Technologies

#artificialintelligence

As digital technology progresses, there has been a growing number of cyberattacks in the last couple of years. By the first half of 2019, 4.1 billion records were exposed due to data breaches. That number is multiplying every day as more people and businesses move online. Cyberattacks are critical for every organization as they can bring the entire organization to a standstill. In such scenarios, security is a necessity for all organizations.


Machine Learning and Artificial Intelligence for Business Recovery after COVID 19

#artificialintelligence

Currently, the world is facing the most challenging time and going through economic turmoil. One of the important priorities of many companies is to recover quickly from the current scenario and be operational as quickly as possible. The coronavirus has impacted many companies and this economic hit is very fast throughout the world. Companies around the globe are looking for stabilizing their business and the recovery. According to the Organization for Economic Co-operation and Development of the reports released on 14th April, consumer expenditure has dropped more than 25% in Canada, France, and Germany in many majority economies, thus causing the slowdown between 20-25%. The Machine Learning (ML) and Artificial Intelligence (AI) can play a major role in the business recovery after and during the COVID 19 pandemic.


Top 10 Books You Must Read Before Starting With Machine Learning

#artificialintelligence

In this article, we are going to list the top 10 Machine Learning books that you should read before you start with it. As you know, Machine Learning is a combination of statistic techniques that help computers learn stuff done by humans. This way we are achieving some results with superhuman precision. Now, as we all know, in order to understand the basics of Machine Learning, it's nice to have some knowledge in different areas of "Mathematics". Before you start reading these top 10 books before starting with Machine Learning, we want to show you two other related articles that you will find very helpful.


Where to find Data for Machine Learning?

#artificialintelligence

Machine learning models learn their behaviour from data. So, finding the right data is a big part of the work to build machine learning into your products. Exactly how much data you need depends on what you're doing and your starting point. There are techniques like transfer learning to reduce the amount of data you need. Or, for some tasks, pre-trained models are available.
