Abstract: With 86 billion neurons and more than 100 trillion synapses, the human brain is one of the most complex systems in our galaxy. Yet, consuming a mere 12.6 watts, the human brain is capable of enormous computation in the presence of huge amounts of neural noise and interference. In this tutorial, we shall explore key principles that make the human brain the ultimate information processing machine. We shall understand the reason behind this superlative performance of the brain: ‘Neurochaos’ – the presence of chaos at different spatial temporal scales in the brain. Chaos refers to the seemingly random-looking unpredictable complex output generated by simple non-linear dynamical systems. Specifically, we shall look at properties of ‘Neurochaos’ that enable efficient encoding of information, communication and learning.

Abstract: Research advances in the last decades have allowed the introduction of Internet of Things (IoT) concepts in several industrial application scenarios, leading to the so-called Industry 4.0 or Industrial IoT (IIoT). Industry 4.0 has the ambition to revolutionize industry management and business processes, enhancing the productivity of manufacturing technologies through field data collection and analysis, thus creating real-time digital twins of industrial scenarios. Moreover, it is vital for companies to be as “smart” as possible and to adapt to the varying nature of digital supply chains. This is possible by leveraging IoT in Industry 4.0 scenarios. When looking only at distinctive use cases for Industry 4.0, manufacturing will drive the most demand for B2B 5G IoT units from 2021 through 2030. At that point, manufacturing will account for over half of all 5G sales for distinctive use cases. For all years from 2021 through 2030, 5G IoT demand will be more moderate for other distinctive use cases within Industry 4.0, including those related to construction and mining, supply chain, and agriculture.

Abstract: Terahertz (THz) frequencies from 0.1 THz to 0.3THz of the electromagnetic spectrum are being explored for ultra-broadband communication networks having channel capacity greater than 1 terabits per second (TB/s) because of the availability of large bandwidth. The world over including in India, extensive research works have been initiated to explore THz frequencies around 0.14 THz and 0.22THz because of relatively low atmospheric attenuations for future 6G wireless communication network. India is expecting for successful launching of 6G using THz frequencies by 2030. The Bharat 6G vision document was launched in March 2023 and the 6G test bed facility is going to be established within our country. This is going to provide an enabling environment for innovation, capacity building, and faster technology adoption for our next generation 6G communication network. 
6G Communication network will meet the rapidly growing demands of high data and speed caused by the increasing users, induction of smart and massive IoTs, fully automated vehicles and other autonomous systems, mobile apps using AI even for wireless medical sensing, imaging and treatment, ultra HD videos, satellite communications, point to point communication network for high security, etc. Although presently launched 5G technology is being upgraded with the use of much higher frequencies up to 0.1THz, work has been initiated for next generation communication networks to meet our future demands. It is well known that the channel capacity of a communication network is directly related to the RF signal bandwidth, and 1 TB of data can be transferred within one second using a carrier signal of 0.22THz with bandwidth around 22 GHz. Some of the key 6G research areas are: THz sensing and communications, ultra-massive MIMO, full duplex communication, new network topologies, ultra-highspeed channel coding, new waveforms, multiple access, reconfigurable intelligent surfaces, distributed computing, AI and machine learning, etc. Many institutions and R&D labs are now working in India for 6G wireless communication networking. Antennas and other passive and active components/devices are being designed and developed to empower a 6G network, and a 6G test bed is being established.
For THz frequency generation and amplification, both solid-state and the vacuum-based devices are being designed and developed based on: (i) up-conversion of present electronic devices, (ii) direct THz generation and (iii) down conversion of optoelectronic devices. The second approach of direct THz generation and amplification is most appealing, and both solid-state devices and vacuum microelectronic devices (VMEDs) are being extensively investigated. Presently, solid-state amplifiers are low-power devices with power not more than 0.1W at 0.22THz frequency although they are highly linear. However, advancements of solid-state devices are extensively going on for increased power and greater bandwidth at THz frequencies. Manufacturing of such devices may soon be possible within our country, also. On the other hand, vacuum devices are compatible with high output power. Among different VMEDs, TWTA (travelling wave tube amplifier) is mostly used for ultra-wideband communication at THz frequencies because of its high output power >100W, large bandwidth >30GHz, high efficiency, and high linear gain >30dB. A planar structure with a sheet electron beam is chosen for a THz TWT. Microfabrication technologies are being used to fabricate the structure with high mechanical precision (within ±1μm) and high surface finish with a roughness <10nm. In this tutorial, the importance of THz technology, important research areas for 6G wireless communication networks, and both the solid-state and the vacuum microelectronic devices for the generation and amplification of THz frequencies will be presented.

Title of the Tutorial: Word-level Language Identification in Code-mixed Dravidian Languages  (90 minutes)
Biography:  Dr. H L Shashirekha received her Master’s and PhD degree in Computer Science from University of Mysore, Mysore. With more than 25 years of teaching experience, she is currently a Professor of Computer Science in the Department of Computer Science at Mangalore University, Mangalore, Karnataka State. Her research areas include Natural Language Processing of low-resource Dravidian languages with a special focus on Kannada - the regional language of Karnataka and Tulu – the local language of Dakshina Kannada. She has broad experience of processing code-mixed text processing, especially in Dravidian languages, and has authored more than 70 scientific publications with a h-index of 11. She is an active researcher and organized several shared tasks in various workshops including Dravidianlangtech2022, ICON2022, Dravidianlangtech2023, and FIRE2023. She was also a keynote speaker at Dravidianlangtech2022@ACL.

Asha Hegde is a Research student in the Department of Computer Science, Mangalore University. Her research areas include Natural Language Processing of low-resource Dravidian languages. She has participated in more than 10 shared tasks and is a highly experienced researcher in organizing shared tasks in low-resource languages, such as Machine Translation in Dravidian languages-ACL2022, CoLI-Kanglish shared task@ICON2022, Sentiment Analysis in Tamil and Tulu- DravidianLangTech@RANLP, and Tulu word-level LI (Coli-Tunglish). She has published more than 13 research articles with H.L. Shashirekha and most of them are on applications of Dravidian languages.

Abstract: Language Identification (LI) in text processing traditionally focuses on automatically detecting languages within a document, predominantly in high-resource languages such as English, Spanish, German, and French. However, recent technological advancements have shed light on the significance of addressing LI challenges in multilingual countries like India, where people blend their mother tongue or local/regional language with English creating code-mixed comments. Indian languages in general, and Dravidian languages, in particular, are marginalized in LI because of lack of resources. To address this issue, we intend to organize a tutorial on” Word-level Language Identification in Code-mixed Dravidian Languages” that aims to address word-level LI in code-mixed Dravidian language texts (Kannada, Tulu, and Tamil). The tutorial covers a preliminary talk on word-level LI in Dravidian languages followed by hands-on (demo codes).

Word-level LI is the identification of language of the words present in any given text. It is a significant task in applications involving code-mixed text as users have the tendency to mix up words of two or more languages (among them one language will usually be English). LI at word-level is modeled as a sequence labeling problem which involves labeling every term/word in a sequence/sentence with one of the languages in a predefined set of languages. Dravidian languages such as Kannada, Tamil, Telugu, Malayalam, Tulu are low-resource languages and word-level LI in these languages is not explored.

Abstract: Malware, short for malicious software is posing a great challenge to Cybersecurity by causing huge damage to enterprises and users. Traditional signature-based malware detection techniques are broadly classified as Static, Dynamic and Hybrid. These techniques have found it challenging to detect malware as it has changed and evolved over time. Machine learning techniques have become popular for malware detection but they are based on heuristic feature engineering, which is expensive and requires domain expertise. Deep learning automates the task of feature engineering. Structural and behavioral features are vital to detect new malware samples. Signature-based mechanisms fail to detect new malware even though they are similar to existing samples as they do not consider these features. The structural similarity between known and new samples has been utilized by the image-based detection and classification techniques which has proven to be effective in this case. The image-based malware detection is platform independent and can detect packed malware. First, I will present conversion of malware binaries into image representation in this session. Second, I will discuss the implementation of deep learning models for intelligent malware detection system. The deep learning models include transfer learning. ImageNet-based models are fine-tuned on the malware image dataset so that the model learn the features within the shorter time and utilize fewer computing re-sources, and obtain the high accuracy malware detection and classification.
