LLM Hallucinations: Causes

A person experiencing LLM hallucinations may have certain underlying conditions that trigger the intense visual or auditory perceptions. These experiences could lead to delusions, paranoia, or confusion. There is no one specific cause of LLM hallucinations as it varies based on individual circumstances, but some common triggers include excessive alcohol and drug use, sleep deprivation, and mental illnesses such as schizophrenia or bipolar disorder.

It is crucial to identify the root cause of LLM hallucinations to prevent them from occurring. Substance abuse treatment and medication may be necessary for those with mental illnesses. Environmental changes such as reducing stress levels and getting enough sleep could potentially reduce LLM hallucinations in individuals who suffer from them.

Individuals with underlying medical conditions or a history of substance abuse have a higher likelihood of developing LLM hallucinations compared to others. It’s important to approach these experiences non-judgmentally and seek professional advice if necessary.

Laion in Open Letter to European Parliament Urges Call to Protect Open-Source AI in Europe

A company named Laion penned an open letter, encouraging the European Parliament to safeguard open-source AI in Europe. It emphasized how free access and transparency of machine learning frameworks are essential tools for academic research and innovation. Such actions can pave the way for a more competitive market and a productive industry. Protecting this area from corporate control could help prevent unfair competition and discriminatory algorithms, which might lead to unethical decisions.

Open-source AI is built around shared software libraries publicly accessible by anyone, leading to more healthy competition among businesses or researchers’ creations. Several sources pointed out that technology companies create deep learning models whose codes they keep secret to preserve their competitive edge. In contrast, developers who use open source software are primarily focused on contributing value through ideas rather than protecting businesses.

In times when public data privacy is increasingly at risk, safeguarding citizen’s human rights should be a top priority alongside innovation in AI. Any restrictions or monopolization of AI could harm the scientific community’s efforts seeking ethical applications of machines in sectors such as healthcare, finance, agriculture, tourism and so on.

Finding Real Partnerships: How Utility Companies Are Evaluating AI Vendors

Utility companies are evaluating AI vendors to find genuine partners. Companies seek vendors with comparable values and a solid understanding of business objectives. Vendors, who can address pain points through their technology, such as reducing costs, not adding additional operational burden or risks, yet providing an effective solution, are highly preferred. Vendors must be able to demonstrate strong knowledge from technical capabilities to regulatory compliance.

Utility companies also understand the importance of agility and responsiveness in meeting their business needs and expect their vendors to have these same qualities. Vendors who do not meet these expectations may negatively impact the company’s bottom line.

In addition, transparency in vendor relationships is key for many utility companies. Open communication between the two parties is essential to achieving shared goals while minimizing misunderstandings or conflicts that could lead to unproductive relationships.

One example of an important factor for a successful vendor relationship was demonstrated by Pacific Gas & Electric (PG&E). PG&E worked with Fathym on a smart grid project where they required open-source solutions rather than an off-the-shelf proprietary option. Fathym provided just that, reducing implementation time while also respecting the customer’s innovation threshold and development environment requirements – ultimately creating a partner-level relationship with PG&E.
