The catch with these free courses is that they don't include certificate of completion or graded assignments and exams. But you can still enroll at any time and start learning at your own pace. Find the best free online courses from Harvard University with edX.

Archetypal analysis (AA) was originally proposed in 1994 by Adele Cutler and Leo Breiman as a computational procedure to extract the distinct aspects called archetypes in observations with each observational record approximated as a mixture (i.e., convex combination) of these archetypes. AA thereby provides straightforward, interpretable, and explainable representations for feature extraction and dimensionality reduction, facilitating the understanding of the structure of high-dimensional data with wide applications throughout the sciences. However, AA also faces challenges, particularly as the associated optimization problem is non-convex. This survey provides researchers and data mining practitioners an overview of methodologies and opportunities that AA has to offer surveying the many applications of AA across disparate fields of science, as well as best practices for modeling data using AA and limitations. The survey concludes by explaining important future research directions concerning AA.

I've always had an interest in programming, because I've always had an interest in computers. I put together websites in HTML as a teenager (which, yes, were hosted on GeoCities) and have been occasionally dabbling in Python since. Yet none of my projects got very far and, apart from my early websites, I never made anything useful. My efforts all followed a familiar pattern: I'd fixate on a particular resource--like an O'Reilly book or an online course--and get started with great enthusiasm, but as I'd realize I was months or years away from creating anything remotely useful, I'd give up. That changed in late 2024 when my general frustration with WordPress, which I was using for my personal website, got the better of me. In a fit, I threw my website's content plus a screenshot of it into Claude 3.5 Sonnet and asked the AI to replicate my site with HTML, CSS, and JavaScript.

'The Big Weekend Show' co-hosts discuss Tinder user traffic peaking during'Dating Sunday.' A judge has dismissed kidnapping and conspiracy charges filed against five Massachusetts college students accused of luring a man to their campus in a "Catch a Predator"-style scheme using a dating app. A Worcester District Court judge dismissed the charges against Kelsey Brainard, Isabella Trudeau, Joaquin Smith, Kevin Carroll and Easton Randall on Tuesday. The decision came after lawyers for the teenage Assumption University students claimed prosecutors lacked probable cause and filed motions to dismiss last month. Information regarding the status of a sixth student, charged as a juvenile, was not immediately available.

For better or worse, AI tools have steadily become a reality of the academic landscape since ChatGPT launched in late 2022. Anthropic is studying what that looks like in real time. On Tuesday, shortly after launching Claude for Education, the company released data on which tasks university students use its AI chatbot Claude for and which majors use it the most. Using Clio, the company's data analysis tool, to maintain user privacy, Anthropic analyzed 574,740 anonymized conversations between Claude and users at the Free and Pro tiers with higher education email addresses. All conversations appeared to relate to coursework.

OpenAI is offering two months of free ChatGPT Plus to all college students, as CEO Sam Altman recently announced ahead of a much-anticipated update to the AI chatbot. The offer is available through May for U.S. and Canadian students only, and can be claimed on the ChatGPT student landing page. According to the site, Existing ChatGPT Plus subscribers and new students will be verified through a system called SheerID to confirm current enrollment. Make note: the subscription will automatically renew at the ChatGPT Plus monthly rate ( 20) if not cancelled before the two months are up. The paid version of ChatGPT includes extended limits on chatting, file uploads, and image generation, as well as advanced voice mode with video and screen sharing, limited Sora access, and new GPT‑4o and o3‑mini models.

Following the release of rival Anthropic's Claude for Education, OpenAI has announced that its 20 ChatGPT Plus tier will be free for college students until the end of May. The offer comes just in time for final exams and will provide features like OpenAI's most advanced LLM, GPT-4o and an all-new image generation tool. "We are offering a Plus discount for students on a limited-time basis in the US and Canada," the company wrote in a FAQ. "This is an experimental consumer program and we may or may not expand this to more schools and countries over time." On top of the aforementioned features, ChatGPT Plus will offer students benefits like priority access during peak usage times and higher message limits.

Stanley Zhong had a 4.42 grade point average, a nearly perfect SAT score, had bested adults in competitive coding competitions and started his own electronic signing service all while still in high school. When it came time to apply to colleges, Zhong's family wasn't overly concerned about his prospects even amid an increasingly competitive admissions environment. But, by the end of his senior year in Palo Alto in 2023, Zhong received rejection letters to 16 of the 18 colleges where he applied, including five University of California campuses that his father had figured would be safety schools. "It was surprise upon surprise upon surprise, and then it turned into frustration and, eventually, anger," his father, Nan Zhong, told The Times in a recent interview. "And I think both Stanley and I felt the same way, that something is really funky here."

Alex Shieh is a student at Brown University. He is making waves and facing charges for asking the school's non-faculty employees what they do all day. A sophomore at Brown University is facing the school's wrath after he sent a DOGE-like email to non-faculty employees asking them what they do all day to try to figure out why the elite school's tuition has gotten so expensive. "The inspiration for this is the rising cost of tuition," Alex Shieh told Fox News Digital in an interview. "Next year, it's set to be 93,064 to go to Brown," Shieh said of the Ivy League university.

Have I told you the story about Bill Gates and me in those early days of personal computing? To be clear: Bill Gates is older than I am. In 1975, as Bill was leaving Harvard to start Microsoft, I had just skipped my last year of high school and started college. I was the youngest student in engineering school that first year -- the same year Bill and I were using the same computer technology: the Altair 8800 and the Digital Equipment PDP-10. My high school computing experience -- like Bill's -- was formative.
