<\/a>What is Artificial Neural Network (ANN)?<\/strong><\/span><\/h2>\n

Artificial neural networks are Computer algorithms that are designed to mimic the human brain\u2019s ability to perform tasks. Hopfield pioneered the work on Artificial neural network (Hopfield Network<\/span>), which was further built upon by Hinton (Boltzmann Machine<\/span>). The two models of Artificial Neural Networks are mentioned below-<\/span><\/p>\n\n\n\n\n
Hopfield Network <\/strong>(Developed by Hopfield)<\/td>\nHopfield network is a form of ANN<\/span> that resembles a human brain’s nerve cells<\/span>. In this network, each neuron is connected to all others. It allowed computers to \u2018learn<\/span>\u2019 and \u2018remember<\/span>\u2019 by processing information through the entire network, not just individual parts.
\nThis leap allowed machines to recognize patterns, and serves as a precursor to modern facial recognition<\/span> and image enhancement technologies<\/span>.<\/td>\n<\/tr>\n
Boltzmann Machine<\/strong>
\n(Developed by Hinton)<\/td>\n		Boltzmann machine<\/span> is another significant ANN model which function by minimizing an energy function, which is a concept rooted in physics. These models performed far more complex and cognitive tasks<\/span> such as data classification<\/span>, pattern generation<\/span> and voice and picture recognition<\/span>.
\nHinton also developed<\/span> backpropagation,<\/span> which allowed neural networks to learn from mistakes and improve through training on large data sets. This has given rise to deep learning<\/span> (a system with multiple layers of networks that continually refine their accuracy).<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

ANN models have led to development and advancement in the field of Artificial Intelligence, Machine Learning, Deep Learning and Artificial Generative Intelligence.<\/p>\n

Artificial Intelligence is being applied in numerous fields<\/span>, including astronomy<\/span>, where it helps scientists analyse massive data sets to discover new information<\/span>. Machine learning focuses efforts on data with the highest potential for groundbreaking discoveries<\/span>. Deep learning is now central to technologies such as voice recognition<\/span>, image identification<\/span>, translation<\/span>, and self-driving cars<\/span>. The field of AI has further advanced to Generative AI, where AI is generating content.<\/p>\n

Relation between AI, Machine Learning, Deep Learning & Generative AI<\/span>
\n<\/strong><\/p>\n\n\n\n\n\n\n
Artificial Intelligence (AI)\u00a0<\/strong><\/td>\nAI is a discipline which focuses on formulating theories<\/span> and methodologies for constructing machines<\/span> that emulate human thought processes and behaviours.<\/td>\n<\/tr>\n
Machine Learning (ML)<\/strong><\/td>\nMachine learning is a subfield of Artificial Intelligence<\/span>. ML involves the development of programs that train models using accessible data<\/span> from sources such as webpages, articles, books, etc. These trained models are then used to make useful predictions for new and never-seen before data<\/span>. The most common ML method to train the models is the supervised learning method<\/span>.<\/td>\n<\/tr>\n
Deep Learning<\/strong><\/td>\nDeep learning is a<\/span> subset of Machine Learning<\/span>. Deep learning is a type of machine learning that uses artificial neural networks<\/span>. These multilayered and interconnected neurons (inspired by the human brain), are used to process complex data<\/span> and make predictions.<\/td>\n<\/tr>\n
Generative AI<\/strong><\/td>\nGenerative AI is a subset of deep learning<\/span>. It uses artificial neural networks to process data using supervised learning methods<\/span>. This large-scale supervised learning technology is termed the Large Language Model<\/span> (LLM<\/span>).<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

<\/a>What are the advantages of AI which are built upon the Artificial Neural Networks (ANN)?<\/strong><\/span><\/h2>\n

1. Writing and advertising-<\/strong> AI is being used as a brainstorming companion<\/span> by the writers. For ex-<\/strong> Drafting press releases<\/span>, language translation<\/span>, creating new advertisements<\/span> based on existing ones.<\/p>\n

2. Reading-<\/strong> Apart from writing, AI technology is used as a reading tool. For ex-<\/strong> Auto Reading customer mails and segregating them based on complaints<\/span>.<\/p>\n

3. Chatting-<\/strong> AI is also being used for many special-purpose chatbot tasks. For ex-<\/strong> Government chatbots<\/span> to help citizens get access to the right information on various schemes and policies.<\/p>\n

4. Security Services- <\/span><\/strong>AI technology built on the advanced Neural Networks can create front-on photos from photos taken at different angles and vice versa. This is being used in face identification systems<\/span> to secure the airports<\/span>, international border check-points<\/span> etc.<\/p>\n

5. Enhanced capability of Search Engine Services-<\/strong><\/span> Advanced Artificial Neural Networks have the capability to take search engine services to the next level. For ex-<\/strong> Text to Image translation <\/span>to provide search results.<\/p>\n

6. Improving Healthcare System-<\/strong> AI technology has the potential to revolutionise the healthcare sector by improving the accuracy of diagnosis. For ex-<\/strong> Conversion of X-ray or any CT scan images to real images<\/span> can improve the accuracy of diagnosis.<\/p>\n\n\n\n

<\/a>What are the Challenges with the Artificial Neural Networks?<\/strong><\/span><\/h2>\n

1. Increased Biases-<\/strong> Artificial Neural Networks can perpetuate and amplify existing biases. These systems can generate biased outputs like offensive language, demeaning imagery, and prejudicial content, if they are trained on biased, non-inclusive data. For ex-<\/strong> US rights group observation<\/span> about an AI-based generative imagery programme showing images of only white men for the prompt<\/span> \u2018CEO<\/span>\u2019.<\/p>\n

2. Threat of Job Losses-<\/strong> There are fears of job losses as AI can prove to be more cost-efficient and productive to firms as compared to human capital. For ex-<\/strong> Customer service jobs are under threat from the AI chatboxes<\/span> (Zomato’s Zia<\/span>).<\/p>\n

3. Use for Malicious Purposes-<\/strong> Generative AI systems based on advanced artificial neural networks can be used to create content for malicious purposes, such as deepfakes<\/span><\/a>, disinformation, and propaganda. Nefarious actors may use AI-generated media to manipulate people and influence public opinion, like use for Post Truth Doctrine<\/span>.<\/p>\n

4. Concern over Data Privacy-<\/strong> There are emerging concerns in regard to data privacy in using AI technology. For ex-<\/strong> Use of AI in healthcare involves collecting private information about individuals<\/span>, which raises concerns about data privacy.<\/p>\n

5. Issues Related to Copyright and plagiarised contents-<\/strong> AI technology has been associated with copyright violations and production of plagiarised content. For ex-<\/strong> Getty Images has sued Stable Diffusion<\/span> (Generative AI Company), accusing them of copyright violations<\/span>.<\/p>\n

6. Limitations in Creativity-<\/strong>\u00a0AI systems lack creativity, originality and human ingenuity as they use past data as a template<\/span> for future work.<\/p>\n

7. Environmental Concerns-<\/strong> AI systems require a lot of computing power, which have grave implications for the environment. For ex-<\/strong> According to analysts, training a transformer model just once with 213 million parameters can emit carbon emissions equivalent to 125 flights between New York and Beijing<\/span>.<\/strong><\/p>\n

<\/a>What should be the way Forward?<\/strong><\/span><\/h2>\n

1. De-biasing while training the AI-<\/strong> We must ensure fairness of the information which is being fed into the system, to ensure that AI doesn\u2019t perpetuate<\/span> or amplify social biases, like gender<\/span> and racial biases<\/span>.<\/p>\n

2. Transparency of information-<\/strong> Users should have transparent information about the limitation and risks of AI.<\/p>\n

3. Privacy protection-<\/strong> The user data and confidentiality must be protected to ensure user privacy. For ex-<\/strong> Strict implementation of data protection laws<\/span>.<\/p>\n

4. Ethical use of AI-<\/strong> We must ensure that AI is used only for beneficial purposes. The push must be made towards universal adoption of the Bletchley Declaration<\/span> by all the countries.<\/p>\n

<\/a>Conclusion<\/strong><\/span><\/h2>\n

India\u2019s progress in AI and scientific research has been hindered by decades of low funding, inefficient governance, and inadequate support for blue-sky research. Many Indian researchers face challenges like resource constraints and administrative burdens, limiting their ability to focus on cutting-edge research. The 2024 Nobel Prize in Physics serves as a reminder of the importance of supporting fundamental research, which often leads to technological breakthroughs.
