Launch of SpaceX Starship 3 rocket ..

This evening at 5.30 PM IST (12 noon GMT) SpaceX Starship3 is going for a launch, streaming live on X . Great news for the whole world, why ??

Jn its quest to start human settlements on Mars, SpaceX has great space fariing plans. As a first step, the biggest and most powerful launch rocket ever, this 121 m tall rocket, *first phase reusable booster* takes the rocket to 70 km altitude. The *second phase is also reusable*, making turning around and relaunching fast and cheap.

While Starship 1 and 2 (20 april 2023 and 18 November 2023) failed, SpaceX believes in failing fast and learning from each failure and improving. They are not sure that this flight 3 also will be successful, it can fail, but they are ready to learn from the failure and be ready for Starship 4 launch in a couple of months time.

Three major tasks are planned in this developmental flight of Starship 3 - firstly open and close the payload door, secondly shuffle fuel from one tank to another, focusing at future refuelling of one Starship by another in space to help long missions to Mars and beyond and thirdly, re-ignition of its engines for a controlled re-entry to earth atmosphere. Stage 2 after re-ignition is supposed to splash into the Indian Ocean, ISRO may be giving expert guidance in this sector of earth re-entry. 

The version 3 Raptor engines with 269 T thrust each, 33 of them, *8877 T total thrust, makes this possibly the most powerful launch rocket in the world*. 

In comparison ISRO most powerful rocket (?) GSLV3 first stage had 5.2 Meganewton thrust (530T thrust each) 2 nos. of solid rocket boosters, total 1060 T thrust.

Whether the Starship 3 fails or not, the learning is what SpaceX is interested .. *FAIL FAST and improve* ..🙏🙏🙂🙂

Avoiding hallucination in AI output ..

AI hallucinations are incorrect or misleading results that AI models generate. These errors can be caused by a variety of factors, including insufficient training data, incorrect assumptions made by the model, or biases in the data used to train the model.Hallucination is one of the man objections raised on the output from Generative AI and is indeed a scary matter to be reckoned. It ca change the context of discussion and evaluation.

Generative AI, while powerful, can sometimes produce hallucinations—nonsensical or inaccurate outputs that deviate from the intended purpose. To improve the quality of AI outputs and prevent hallucinations, the industry employs various technical methods. Here are key strategies that can be used to handle hallucination:

1. Rigorous Testing and Evaluation:
   • Testing AI models rigorously before deployment and evaluating them continuously are vital steps to prevent hallucinations and enhance overall performance
   • Ongoing evaluation allows for adjustments, retraining, and ensures that human oversight is available to filter and correct hallucinatory outputs
2. Improved Data Quality:
   • Providing generative AI models with well-structured, diverse, balanced, and augmented training datasets can significantly influence their behavior and minimize biases in outputs
   • High-quality training data helps AI models gain a better understanding of real scenarios, reducing the likelihood of generating hallucinatory content
3. Model Regularization:
   • Implementing model regularization techniques can help control hallucinations by penalizing unrealistic outputs and encouraging models to align with the training data distribution
   • This approach minimizes the generation of irrelevant or nonsensical content by ensuring that outputs are more aligned with the intended purpose.
4. Human-in-the-Loop Validation:
   • Incorporating human reviewers in the generative AI pipeline plays a crucial role in preventing hallucinations by providing human oversight and validation of AI-generated content
   • Human reviewers can identify inaccuracies, provide feedback, and make corrections to ensure that AI outputs are accurate, coherent, and aligned with expectations.
5. Continuous Monitoring and Validation:
   • Regular model evaluation and continuous monitoring of AI performance are essential to identify patterns of hallucinations and make necessary adjustments to the training process
   • By closely monitoring AI outputs, developers can address emerging issues promptly and ensure that the models generate reliable and trustworthy content.

By implementing these technical methods—such as rigorous testing, improved data quality, model regularization, human-in-the-loop validation, and continuous monitoring—generative AI industry aims to reduce hallucinations, enhance output quality, and ensure that AI systems generate accurate, coherent, and reliable content aligned with user expectations.

Avoiding bias in AI output ..

Bias in AI output refers to the presence of systematic prejudices or inaccuracies in the results generated by artificial intelligence algorithms. This bias can stem from various sources within the AI development process, leading to unfair, discriminatory, or skewed outcomes.

There are several types of bias that can manifest in AI output:

• Selection Bias: Arises when training data is not representative of the reality it aims to model, leading to unrepresentative datasets and biased outputs
• Confirmation Bias: Occurs when AI systems rely excessively on pre-existing beliefs or trends in data, reinforcing existing biases and hindering the identification of new patterns
• Measurement Bias: Arises when collected data systematically differs from the actual variables of interest, impacting the accuracy and reliability of AI predictions
• Stereotyping Bias: Reinforces harmful stereotypes, such as inaccuracies in facial recognition systems or language translation tools

Companies are motivated to tackle the challenge of bias in AI not only to achieve fairness, but also to ensure better results. If the public end user gets the feeling that a particular AI system is biased it can lead to endless litigation and court cases. In the real world, it is difficult to eliminate systemic racial and gender bias, likewise eliminating bias in AI is no easy task. This bias can be a major concern in AI systems when organisations provide AI resources to their customers. 

To ensure that any AI does not have any bias, several measures can be wilfully and consciously implemented:

1. Transparency: Ensure that the said AI should maintain transparency in its operations, algorithms, and decision-making processes. By providing clear information on how the AI functions and how results are generated, users can better understand the system's workings
   
   
2. Diverse Data Sources: Utilizing a wide range of data sources helps mitigate bias by offering a more comprehensive view of information. When diverse perspectives and sources are incorporated, the AI can reduce the risk of bias in its responses
   
   
3. Regular Audits: The organisation needs to conduct regular audits and evaluations of the AI system that can help identify and address any biases that may exist. Continuously monitoring and reviewing the AI's performance, are the only ways by which biases can be detected and rectified promptly
   
   
4. Ethical Guidelines: Adhering to ethical guidelines and standards in AI development is crucial for ensuring fairness and impartiality. Following ethical principles and guidelines in the training of the AI system, AI can uphold integrity and minimize bias in its operations
   
   
5. User Feedback: Encouraging user feedback and actively seeking input from users can help identify potential biases or issues within the system. When the interaction with the end user is strong by incorporating user feedback into the development process, any AI can address concerns and improve its performance. 

Continuous Improvement or the Japanese term, Kaizen is the key to giving better output from an AI system. Organisations focusing on providing AI services or Intelligence-as-a-Service (I-a-a-S) need to be super vigilant and careful that such inaccuracies and biases do not creep into their training data. 

In the next couple of years we can expect AI systems to be super powerful and would have permeated many core areas of human existence, enterprise, services and development particularly the environmental, educational, energy, utilities, biotech and healthcare systems. With proper training data from authorised sources and correction to remove any bias in the training data, right at the source, we can ensure the AI system does not  output erroneous and biased results.

SpaceX phenomenal growth..

SpaceX has shown remarkable growth over the years. In 2012, its value doubled to $4.8 billion all the way to the present $180 billion.

By 2023, SpaceX aimed for 100 launches and exceeded expectations with 105-110 launches.

The company's Falcon family achieved a world record with 96 launches in 2023, surpassing their previous yearly record of 61 launches.

Notably, SpaceX completed 100 launches within a year between December 2022 and December 2023. This growth is evident in their consistent improvement and increased launch cadence, marking significant milestones in the space industry.

In 22 years after establishment of SpaceX in 2002 by Elon Musk, see the quantum of outstanding space missions, one partly successful lunar mission, establishing the satellite network Starlink for providing excellent Internet bandwidth both across the oceans and land, are mind boggling to come out of the hard work, ingenuity and imagination of an individual. 

Presently Internet access is continuously available only over land and expensive. Starlink now with only 5000 satellites and another 40,000 plus ready for launch will help reduce costs and improve global Internet access. Future Mars related exploration will be  from a SpaceX lunar base, all these actions are out of this world and set to benefit humanity beyond what human mind can even conceive. Future SpaceX growth is bound to be  synonymous with human development.. 👌👌🙏
