MIT researchers found a way to remove data that makes AI models biased, making them fairer without losing accuracy.
The method fixes "worst-group error," where AI struggles with underrepresented groups, by removing harmful data.
It removes fewer data points than other methods but still improves accuracy and fairness.
The technique works with unlabeled data, making it easier to find hidden biases.
This method is simple, flexible, and easy to use with different AI systems.

Note: Time crystals are a new phase of matter that oscillates without energy input, providing stability in quantum systems. This innovation demonstrates their potential to improve error tolerance and scalability in quantum computing.
By leveraging principles of superposition and entanglement, quantum computers can process vast amounts of data in parallel, potentially revolutionizing areas such as climate modeling, drug discovery, and financial modeling by significantly reducing computation times.
Quantum systems are prone to errors due to environmental noise, quantum decoherence, and the instability of qubits. Time crystals provide a more stable environment by maintaining coherence over extended periods, reducing error rates.
In a quantum computer, time crystals can serve as stable and reliable clocking mechanisms or error-resistant components, thanks to their unique ability to cycle in fixed states without external energy input.
Qubits encode information as quantum states, which allow simultaneous exploration of multiple solutions. This makes solving problems like prime factorization or optimization tasks exponentially faster than classical methods.
Frank Wilczek theorized time crystals as a new phase of matter that defies traditional thermodynamic equilibrium. Although initially dismissed as unfeasible, advancements in quantum technology have since demonstrated their existence and utility.

Note: Germany’s economy has slowed with little growth and is expected to contract for the year. Bosch plans to cut 5,500 jobs due to high energy prices, bureaucracy, and aging infrastructure.
Comment: The economic crisis has led to political instability, with a snap election looming.
The political paralysis in Germany has been exacerbated by the collapse of the ruling coalition, leaving voters uncertain about the country’s future direction. The economy, struggling with stagnation and inflation, has become the central issue in the upcoming election, with citizens concerned about their financial stability.
The economy recorded only 0.1% growth from July to September and is expected to contract for the year. High energy prices and other factors contributed.
Bosch, Germany’s largest auto supplier, is cutting jobs due to economic challenges.
The political paralysis under the previous government exacerbated the economic situation.
Economists predict that growth will not return in 2025 unless significant changes are made to the economy.

“UPOP is a great opportunity for MIT sophomores to develop important skills that will complement what they are learning in the classroom and can help them to effectively communicate and demonstrate their value in a professional setting,” says Kendel Jester, assistant director for early career engagement in MIT Career Advising and Professional Development (CAPD).
UPOP uses experiential learning to bolster students’ professional development and teaches them effective communication, teamwork, and problem-solving skills in an interactive environment.
“UPOP helps sophomores figure out what they want to do after graduation by connecting them with professionals in a variety of careers,” says Marianne Olsen, an MIT/UPOP alumna whose company, Chartwell, is part of the employer network.
UPOP’s mission puts students’ career readiness needs as a No. 1 priority, and the program is constantly evolving to meet those needs.
“Considering all the networking practice and professional skills that you get to learn from experienced mentors, TTW is definitely worth your time,” says Ahmed. “You get an opportunity to learn more about different fields of work from experts. You also get the chance to learn about the communication and emotional intelligence skills that are necessary to be successful at your job, which we may not get the chance to practice in our academic/technical classes.”
