Sentiment Analysis with XAI in Human-Computer Interaction

Imagine chatting with a bot that truly gets how you feel—whether you're excited, frustrated, or confused. That’s the power of sentiment analysis combined with explainable AI (XAI) in human-computer interaction (HCI). For both engineering and non-engineering students, this article explores how BERT (a cutting-edge language model) and SHAP (a tool to explain AI decisions) team up to make chatbots more empathetic and create user-friendly educational tools.

What is Sentiment Analysis?

Sentiment analysis is like teaching a computer to read emotions in text. For example, if you type, “I’m struggling with this math problem,” the system detects your frustration. It’s widely used in chatbots, customer service, and even educational apps to tailor responses based on your mood.

Why BERT?

BERT (Bidirectional Encoder Representations from Transformers), developed by Google, is a superstar in natural language processing (NLP). Unlike older models that read text one way (left-to-right or right-to-left), BERT understands context by looking at both directions. For instance, in the sentence “I love this book, but the ending was sad,” BERT captures the mixed emotions accurately.

For students: Think of BERT as a super-smart librarian who knows the meaning of every word in a book by understanding the whole story, not just a single page.

Why SHAP?

AI models like BERT can seem like mysterious black boxes—great at giving answers but terrible at explaining why. That’s where SHAP (SHapley Additive exPlanations) comes in. SHAP breaks down BERT’s decisions to show which words in your sentence influenced its prediction. For example, in “I’m so happy with my grades,” SHAP might highlight “happy” and “grades” as key drivers of the positive sentiment.

For non-engineers: Imagine SHAP as a detective who explains exactly which clues (words) led to the AI’s conclusion.

How It Works: BERT + SHAP in Action

Let’s break it down with an example:

1. Input Text: A student types, “I don’t understand this coding assignment, it’s so hard.”

2. BERT’s Role: Using the Hugging Face library (a popular platform for NLP models), BERT processes the text and predicts a negative sentiment with 90% confidence.

3. SHAP’s Role: SHAP analyzes BERT’s decision and shows that words like “don’t understand” and “hard” were the biggest contributors to the negative prediction.

4. Output: The chatbot responds, “I’m sorry you’re finding it tough. Let’s break down the assignment step-by-step. Where are you stuck?”

Impact on Human-Computer Interaction

Combining BERT and SHAP has game-changing effects:

1. Empathetic Chatbots: By understanding emotions and explaining decisions, chatbots can respond with sensitivity. For example, an educational chatbot might say, “I see you’re frustrated. Let’s try a simpler example,” instead of a generic reply.

2. User-Friendly Educational Tools: Imagine an app that adjusts lessons based on your mood. If you’re confused, it slows down; if you’re excited, it challenges you further. This personalization makes learning more engaging.

3. Trust in AI: SHAP’s explanations build trust by showing why the AI made a decision, which is crucial for students relying on AI tools for learning.

Conclusion

Sentiment analysis with BERT and SHAP is revolutionizing human-computer interaction by making AI smarter and more transparent. For engineering students, it’s an exciting field to dive into with tools like Hugging Face and SHAP. For non-engineering students, it’s a glimpse into how AI can make technology feel more human, especially in education. Whether you’re coding or just curious, this tech is shaping a future where machines don’t just think—they understand.

AI in Geotechnical Engineering: Landslide Prediction

As the rainy season sweeps across India, the risk of landslides in hilly regions like the Himalayas, Western Ghats, and the Northeast intensifies. Artificial Intelligence (AI), specifically Graph Neural Networks (GNNs) built using the PyG (PyTorch Geometric) library, is transforming geotechnical engineering by predicting landslides with remarkable accuracy. This article, crafted for both engineering and non-engineering students, explains how GNNs model soil dynamics to forecast landslides and save lives through early evacuations.

What is Landslide Prediction with AI?

Landslides occur when soil, rocks, or debris slide down slopes, often triggered by heavy rain, earthquakes, or human activity. Predicting them involves analyzing complex factors like soil type, slope angle, rainfall, and vegetation. Traditional methods rely on physical models, but AI, particularly GNNs, offers a data-driven approach to capture these dynamic interactions.

Why Graph Neural Networks (GNNs)?

GNNs are a type of AI model designed to work with data structured as graphs—networks of nodes (points) and edges (connections). In landslide prediction:

• Nodes represent soil patches, weather stations, or sensors.

• Edges connect these nodes based on spatial relationships (e.g., proximity) or physical interactions (e.g., water flow).

• PyG is a Python library that makes it easy to build and train GNNs using PyTorch.

GNNs excel at modeling soil dynamics because they capture how changes in one area (e.g., heavy rain on a slope) ripple through connected regions. For example, if a soil patch becomes waterlogged, GNNs predict how it affects nearby areas, helping forecast potential landslide zones.

For non-engineers: Think of GNNs as a digital map where each point (node) talks to its neighbors to predict danger, like friends warning each other about a storm.

How It Works: GNNs in Action

Here’s a simplified workflow for landslide prediction using GNNs:

1. Data Collection: Sensors and satellites gather data on rainfall, soil moisture, slope angles, and vegetation in a hilly region.

2. Graph Construction: Engineers create a graph where nodes are soil patches or sensor locations, and edges represent spatial or physical connections.

3. GNN Processing: Using PyG, the GNN analyzes the graph, learning how factors like rain and soil type interact to predict landslide risk.

4. Output: The model generates a risk map showing high-risk zones, enabling authorities to issue evacuation alerts.

AI-powered landslide prediction using GNNs and PyG is a game-changer for geotechnical engineering, especially in India’s monsoon-prone hilly regions. For engineering students, it’s an exciting opportunity to dive into GNNs and PyG to build life-saving models. For non-engineering students, it’s about using risk maps to stay safe and informed. Together, this technology is building a safer future, one prediction at a time.

Role of XAI

XAI tools, like SHAP or LIME, analyze the decisions made by AI-driven security tools in Kali Linux. For example, if an AI flags a network port as vulnerable, XAI explains which factors (e.g., outdated software, open port) contributed most to the risk score. This transparency builds trust and helps non-technical stakeholders understand the findings.

How It Works: Penetration Testing with Kali Linux

Penetration testing (pen testing) is the process of ethically hacking a system to find weaknesses. Here’s a simplified workflow:

1. Reconnaissance: Use Nmap to scan a network and identify devices and open ports.

2. Vulnerability Scanning: Tools like OpenVAS detect weaknesses, such as outdated software.

3. Exploitation: Metasploit simulates an attack to test if vulnerabilities can be exploited.

4. Reporting with XAI: XAI tools explain the findings, showing which vulnerabilities are critical and why, for clear reporting to clients or teams.

Ethical hacking with Kali Linux and XAI is a powerful way to secure digital systems while preparing for a thriving career in cybersecurity. For engineering students, it’s a chance to master tools like Nmap and Metasploit and enhance them with XAI. For non-engineering students, it’s about understanding risk reports and contributing to a safer digital world.

4. Ethics Bit: The Algo Dilemma

Should AI Predict Student Dropout Risks in India?

In India, where education is a cornerstone of progress, school and college dropout rates remain a pressing challenge. According to the UDISE+ 2021-22 data, the overall school dropout rate in India is 1.5%, a slight improvement from 1.8% the previous year, but the secondary level sees higher rates, with some states reporting up to 20% dropouts. In higher education, approximately 30% of students in colleges and universities discontinue their studies before their second year. With such alarming statistics, Artificial Intelligence (AI) is emerging as a tool to predict student dropout risks, offering hope for early intervention. But here’s the dilemma: could these predictive models unfairly label students, leading to stigmatization? This article, written for engineering and non-engineering students, weighs the benefits of AI-driven early intervention against the risks of labeling, using recent data and research to spark reflection.

The Dropout Crisis in India

India’s education system faces unique challenges. The 75th Round of the National Sample Survey (2017-18) highlights that financial constraints, lack of interest in studies, distance to schools, and marriage (especially for female students) are major reasons for dropouts among those aged 18–35. In rural areas, 12.6% of students drop out before completing secondary education, while urban areas fare slightly better at 9.6%. In higher education, the All India Survey on Higher Education (AISHE) 2020-21 reports a Gross Enrolment Ratio (GER) of only 27.3% for ages 18–23, far from the target of 50% by 2030. These numbers underscore the urgency of addressing dropouts, especially as dropouts face a 20% higher likelihood of unemployment compared to graduates.

How AI Predicts Dropout Risks

AI, particularly machine learning (ML) models like Decision Trees, Neural Networks, and XGBoost, can analyze vast datasets to identify students at risk of dropping out. These models use:

• Academic Data: Grades, attendance, and course participation.

• Demographic Data: Age, gender, and socio-economic status.

• Behavioral Data: Engagement on learning management systems (LMS) like Moodle.

For example, a 2024 study using a Hybrid Logistic Regression and Neural Network (HLRNN) model achieved 96% accuracy in predicting dropouts by analyzing factors like grades and financial status. Explainable AI (XAI) tools, such as SHAP and LIME, further enhance these models by explaining which factors (e.g., low grades, frequent absences) contribute most to a student’s risk score. This transparency helps educators understand and act on predictions.

For engineering students: Think of AI as a weather forecast for education—it predicts the “storm” of dropout risk by analyzing patterns in data, just like predicting rain from cloud patterns.

For non-engineers, it’s like a doctor diagnosing a patient’s risk of illness based on symptoms, with XAI explaining the diagnosis in plain language.

A 2021 Cornell study found that including protected attributes like gender or minority status in AI models doesn’t significantly improve accuracy, suggesting careful data selection to avoid bias. Mislabeling could also discourage students, especially in India’s competitive education system, where social stigma around failure is strong.

Conclusion

India’s dropout crisis—1.5% in schools and 30% in higher education—demands innovative solutions. AI, with models like HLRNN achieving 96% accuracy, can identify at-risk students and enable interventions like counseling or financial aid. Yet, the risk of stigmatization looms large, especially in a society sensitive to academic failure. By pairing AI with XAI and human oversight, India can harness technology to keep students in school while avoiding unfair labels. Whether you’re an engineering student coding the next predictive model or a non-engineering student advocating for fair education, the question isn’t just should AI predict dropout risks—it’s how we can do it ethically to build a brighter future.

Statistics of the Week

The data illustrates how workers with higher educational qualifications, such as graduates and postgraduates, are still largely employed in non-specialised roles. While 38.23% of graduates occupy jobs that are somewhat related to their qualifications, only 8.25% secure roles that require the level of competency expected from their education.

The Survey, which relies on data from the Institute for Competitiveness, states that over 50% of graduates are currently employed in “elementary” or “semi-skilled” jobs, roles that do not require the educational qualifications they possess.

This underemployment trend is also prevalent among postgraduates, with 44% in similar low-skill roles. The findings suggest a significant disconnect between the education system’s output and the skills demanded by the workforce.

One of the key reasons identified for this mismatch is the lack of sufficient vocational and specialised training, which leaves many graduates inadequately prepared for the professional demands of the market. The Survey emphasises that educational outcomes across different levels need a major overhaul to address the growing skills gap.
