If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
Well, wondering what is NLTK? the Natural Language Toolkit, or more commonly NLTK, is a suite of libraries and programs for symbolic and statistical natural language processing (NLP) for English written in the Python programming language. It was developed by Steven Bird and Edward Loper in the Department of Computer and Information Science at the University of Pennsylvania. It is necessary to convert the text to lower case as it is case sensitive. Tokenize sentences to get the tokens of the text i.e breaking the sentences into words.
Everyone despises CAPTCHAs (humans, since bots do not have emotions) -- Those annoying images containing hard to read the text, which you have to type in before you can access or do "something" online. CAPTCHAs (Completely Automated Public Turing tests to tell Computers and Humans Apart) were developed to prevent automatized programs from being mischievous (filling out online forms, accessing restricted files, accessing a website an incredible amount of times, and others) on the world wide web, by verifying that the end-user is "human" and not a bot. Nevertheless, several attacks on CAPTCHAs have been proposed in the past, but none has been as accurate and fast as the machine learning algorithm presented by a group of researchers from Lancaster University, Northwest University, and Peking University showed below. One of the first known people to break CAPTCHAs was Adrian Rosebrock, who, in his book "Deep Learning for Computer Vision with Python,"  Adrian goes through how he bypassed the CAPTCHA systems on the E-ZPass New York website using machine learning, where he used deep learning to train his model by downloading a large image dataset of CAPTCHA examples in order to break the CAPTCHA systems. The main difference between Adrian's solution and the solution from the research scientists from Lancaster, Northwest, and Peking, is that the researchers did not need to download a large dataset of images to break the CAPTCHAs system, au contraire, they used the concept of a generative adversarial network (GAN) to create synthesized CAPTCHAs, along with a small dataset of real CAPTCHAs to create an extremely fast and accurate CAPTCHA solver.
With the recent tweet on Neuralink, Elon Musk again hit the headlines this week where he stated that the company is going to update on the progress of this mysterious company in the coming month. In fact, the last major update came from this brain-machine interface company last year around the same time, where he spoke about the technology "threads," surpassing the traditional ones, which can be implanted in human brains to solve some of the brain disorders people are facing. He ultimately revealed his interest "to achieve a symbiosis with AI" by merging technology with human brains and not taking over. This raises a serious question -- can Elon Musk build cyborgs in the near future? SpaceX and Tesla CEO, Elon Musk has been known for bringing extraordinary ideas to life like electric cars, sending rockets to Mars, and creating solar cities, to name a few.
SHANGHAI, July 11 (Xinhua) -- Due to COVID-19, the World Artificial Intelligence Conference (WAIC) 2020 in Shanghai this week adopted a hybrid model where offline exhibitions and online displays took place simultaneously to showcase the latest artificial intelligence (AI) applications and frontier development. More than 500 AI experts and executives, including Nobel laureates and Turing Award winners, attended this year's WAIC held from Thursday to Saturday with the theme of "Intelligent Connectivity, Indivisible Community." Photo taken on July 3, 2020 shows the research center of the Chinese e-commerce giant Alibaba on the "AIsland" of Zhangjiang Science City in Pudong New Area, east China's Shanghai. AI has already demonstrated its potential to transform societies, economies and industries, but this is just the beginning, according to experts at the conference. WAIC plays a critical role in bringing people together to learn from one another and identify ways of collaborating to achieve more.
