Self-supervised learning techniques can bridge the gap between human-like reasoning and traditional deep learning models in real-world decision-making by enabling models to learn from unlabeled data, mimicking the way humans acquire knowledge through observation and experience. Unlike traditional models that require extensive labeled datasets, self-supervised learning generates its own labels from the data itself, allowing for a richer understanding of context and relationships. This approach enhances the model's ability to generalize and adapt to new situations, fostering a form of reasoning that is more akin to human cognition. By leveraging vast amounts of unstructured data, self-supervised learning empowers AI systems to make more nuanced and informed decisions, ultimately aligning their decision-making processes more closely with human-like reasoning.

Self-supervised learning (SSL) offers promising avenues to bridge the gap between human-like reasoning and traditional deep learning models in real-world decision-making by addressing some of the key limitations of purely supervised approaches. Here's how:

1. Learning Rich Representations from Unlabeled Data:

• Mimicking Human Experience: Humans learn a vast amount about the world through observation without explicit labels. SSL allows models to tap into the abundance of unlabeled data, learning underlying structures, patterns, and relationships inherent in the data, similar to how humans build an understanding of the world through experience.
• Overcoming Label Scarcity: Real-world data is often unlabeled, and manual annotation is expensive and time-consuming. SSL techniques enable models to learn useful representations from this readily available data, reducing the reliance on large, labeled datasets required by traditional supervised learning. This is crucial for applying AI in domains where labeled data is scarce.

2. Fostering Generalization and Robustness:

• Learning Invariant Features: By training on pretext tasks that require understanding the underlying structure of the data (e.g., predicting masked words, image in-painting, video sequence ordering), SSL encourages models to learn more generalizable and robust features that are less sensitive to superficial variations or noise. This can lead to better performance on downstream real-world tasks, which often involve noisy and diverse inputs.
• Improved Handling of Novel Situations: The rich representations learned through SSL can equip models with a better understanding of the data's inherent structure, potentially allowing them to reason more effectively in novel or unseen situations, a hallmark of human intelligence.

3. Enabling Contextual Understanding and Reasoning:

• Capturing Dependencies: Many SSL techniques, particularly in Natural Language Processing (NLP) and video analysis, focus on predicting missing parts or the order of sequences. This forces the model to understand the contextual dependencies within the data, a crucial aspect of human reasoning. For example, predicting a masked word requires understanding the surrounding sentence, mimicking how humans use context to comprehend language.
• Building Semantic Understanding: By learning to relate different parts of the input data, SSL can help models develop a deeper semantic understanding, moving beyond simple pattern matching. This understanding can be leveraged for more sophisticated reasoning in downstream tasks.

4. Facilitating Transfer Learning:

• Effective Pre-training: Models pre-trained using SSL on large unlabeled datasets learn general-purpose representations that can be effectively transferred and fine-tuned for various downstream tasks with limited labeled data. This transfer learning capability allows models to leverage prior knowledge, similar to how humans apply knowledge learned in one domain to another.

Specific Self-Supervised Learning Techniques and Their Contribution:

• Masked Autoencoding (e.g., BERT, MAE): By predicting masked parts of the input (text, images), these models learn contextual relationships and develop strong feature representations. This mimics how humans use context to fill in missing information and understand the whole.
• Contrastive Learning (e.g., SimCLR, MoCo): By learning to distinguish between similar and dissimilar data points, these methods learn robust and discriminative representations. This relates to how humans learn by identifying similarities and differences.
• Generative Pre-training (e.g., GPT): By predicting the next element in a sequence, these models learn the underlying structure and dependencies in the data, enabling them to generate coherent and contextually relevant outputs. This mirrors human abilities in language generation and sequential reasoning.
• Pretext Tasks in Vision (e.g., Jigsaw Puzzles, Rotation Prediction): Solving these tasks forces the model to understand spatial relationships and visual features, leading to better image understanding.

Limitations and Challenges:

• Pretext Task Relevance: The effectiveness of SSL heavily relies on the design of the pretext task and its correlation with the downstream task. A poorly designed pretext task might not lead to useful representations for the target problem.
• Reasoning Complexity: While SSL improves representation learning and contextual understanding, it doesn't inherently equip models with explicit logical reasoning capabilities that humans possess. Integrating symbolic reasoning or neuro-symbolic approaches with SSL might be necessary to achieve more advanced forms of human-like reasoning.
• Evaluation Metrics: Evaluating the quality of learned representations and their impact on downstream reasoning tasks remains an active area of research.

In conclusion, self-supervised learning is a crucial step towards bridging the gap between traditional deep learning and human-like reasoning in real-world decision-making. By leveraging the vast amounts of unlabeled data and focusing on learning inherent data structures and contextual relationships, SSL empowers models to develop richer, more generalizable representations that can lead to more robust, adaptable, and context-aware AI systems.

However, it's important to recognize that SSL is not a complete solution and further research is needed to integrate it with other AI paradigms to achieve truly human-level reasoning.

Self-supervised learning (SSL) bridges the gap between human-like reasoning and traditional deep learning by enabling models to learn from unlabeled data, improving generalization, causal understanding, and adaptability to real-world changes. Unlike traditional models that rely on labeled data, SSL helps in reasoning, few-shot learning, and multimodal understanding, making AI more robust and effective in decision-making tasks like autonomous driving, healthcare, and robotics.

Thanks for raising such a thoughtful and timely question. You’ve hit on one of the biggest challenges in AI today: how do we move beyond models that are great at spotting patterns—but poor at thinking—toward systems that can reason more like humans do?

As someone who works in math education, cognitive science, and AI, I see this not just as an engineering puzzle but as a deeper question about knowledge itself: What is reasoning, really? And how can machines come close to the kind of flexible, context-aware, and often symbolic thinking that even children demonstrate as they learn?

1. Why Traditional Deep Learning Falls Short

Most deep learning models today are trained on massive amounts of labeled data—think millions of images tagged “cat” or “dog.” They’re excellent at recognizing patterns within the kinds of examples they’ve seen before. But they struggle badly when faced with anything new or unexpected.

Humans, by contrast, are remarkably adaptable:

• We learn from very few examples (a child doesn’t need 10,000 cats to recognize a new one).
• We combine ideas in creative ways (e.g., imagining a “flying car” even if we’ve never seen one).
• We think in terms of cause and effect, not just correlations (“If I drop this, it will break”—not just “things fall down”).
• We know when we’re unsure—a kind of self-awareness most AI lacks.

2. How Self-Supervised Learning Helps

Self-supervised learning (SSL) offers a smarter path forward. Instead of relying on human-labeled data, SSL lets models learn by figuring out structure within the data itself. For example:

• Predicting missing words in a sentence.
• Reconstructing a corrupted image.
• Matching different views of the same object (like a photo taken from two angles).

This mirrors how people learn: by exploring the world, making predictions, and adjusting when they’re wrong—all without needing someone to label every experience.

Thanks to SSL, today’s models can pick up on deeper structures—like how objects stay the same even when hidden (object permanence), how scenes are organized in space, or how events unfold over time. In vision, models like DINO or MAE start to “see” parts and wholes the way humans do. In language, large models absorb grammar and meaning just by predicting the next word—no explicit rules needed.

3. But Representation Isn’t Enough—We Need Real Reasoning

Here’s the catch: having rich internal representations is necessary, but not sufficient for reasoning. To get closer to human-like thinking, we need to build more into the system:

• Connect symbols to meaning: Help models link continuous patterns (like neural activations) to discrete, manipulable concepts—think “apple,” “cause,” or “if-then.” This is where neuro-symbolic approaches come in.
• Build internal models of the world: Let AI simulate what might happen next—like how a ball rolls or how a conversation might unfold—so it can plan and anticipate.
• Focus on causes, not just patterns: Train models to find stable, underlying mechanisms rather than surface-level coincidences (e.g., “smoke implies fire,” not just “smoke and fire often appear together”).
• Let models “think out loud”: Techniques like chain-of-thought prompting encourage models to break problems into steps—mimicking the inner dialogue we use when solving a tough math problem.

4. Real Decisions Need More Than Accuracy

In real-world settings—like healthcare, education, or self-driving cars—AI must do more than be “right on average.” It needs to:

• Know when it’s uncertain—and say so. Bayesian or evidence-based methods can help models express confidence levels, which is crucial for safety.
• Adapt to context. A doctor’s reasoning changes based on a patient’s history; a teacher adjusts based on a student’s confusion. AI should do the same—through techniques like prompt tuning, modular design, or meta-learning.
• Align with human values. Reasoning isn’t just logical—it’s also ethical and goal-oriented. We need to bake in principles (like fairness or pedagogical care) directly into how models learn, not just tack them on at the end.

5. What Math Class Teaches Us About Learning

In my work with students, I’ve seen that real understanding comes from productive struggle—trying, failing, questioning, and revising mental models. This is strikingly similar to how SSL works: learn by making predictions and correcting errors.

Imagine if AI systems were encouraged not just to give answers, but to explain their reasoning, ask clarifying questions, or even challenge their own assumptions—like a student working through a proof. Techniques like Socratic prompting or requiring self-generated justifications could nudge models toward this kind of proto-reasoning.

Self-supervised learning isn’t a magic fix—but it’s our best shot at building AI that learns from raw experience, like humans do. The next step is to combine SSL with tools for symbolic thinking, causal understanding, and self-reflection.

We don’t need machines to be human. But in high-stakes domains—where decisions affect lives—we absolutely need them to be robust, adaptable, and explainable. And that means moving beyond pattern matching toward something closer to genuine reasoning.

Thank you, Sergio Leal Ramirez , for such a well-structured and insightful explanation. You’ve captured the essence of how self-supervised learning builds foundational representations that can generalize across tasks. I especially appreciate your examples from NLP and computer vision they show how SSL is already moving toward more adaptive and context-aware reasoning.

To bridge the gap with human-like decision-making, I believe SSL needs to go further by integrating causal inference, temporal reasoning, and multimodal understanding. These elements help models not just recognize patterns but also interpret context and anticipate outcomes, much like humans do in uncertain environments.

Your response adds real clarity to this evolving conversation. I look forward to learning more from your work.

I also want your opinion on my current paper:

Thank you so much Ghulam Muhayyu Din, for your thoughtful words —and for inviting me into this meaningful exchange.

These aren’t just fancy technical upgrades—they’re essential ingredients for any system that hopes to reason like a human, especially in messy, uncertain real-world situations.

I’ve read both of your papers carefully, and I’d love to share some reflections that blend technical insight with ideas from learning science and systems thinking.

1. “Comparative Analysis on AI-Driven Human Digital Twin for Personalized and Predictive Medicine”

This is a bold and timely vision: using AI-powered digital twins to shift medicine from reacting to anticipating. You rightly treat the Human Digital Twin (HDT) not as a static data dashboard, but as a living, evolving model that weaves together genes, body signals, behavior, and environment.

What stands out:

• Your approach mirrors how humans actually learn about their own bodies—through constant feedback from the world around them. That’s very much in line with modern ideas about embodied cognition.
• The three feedback loops you describe (monitoring, tuning, and care management) show a deep grasp of how adaptive systems work. In fact, it reminds me of Vygotsky’s idea of the “zone of proximal development”—where support is tailored to what a person is ready to learn next. Here, the HDT isn’t just predicting; it’s scaffolding care in real time.
• You take ethics and validation seriously—not as an afterthought, but as core to the design. That’s rare and commendable.

A few ideas to consider:

• Could the HDT also act as a learning partner for patients? For example, instead of just saying “take this medicine,” it might explain why—helping people build health literacy and agency.
• You might strengthen the link to self-supervised learning. For instance, could models pre-trained on years of a patient’s unlabeled health data (like lab results or wearable readings) learn to predict future risks in a way that supports causal reasoning?
• Your vision for using drones (UAVs) to deliver emergency meds guided by the HDT is exciting! Just keep asking: Does this empower the patient, or make them more dependent on tech? The human should always remain at the center.

2. “Supply Chain System Based on Pharmaceutical Industry 4.0 Platform”

This paper tackles a critical real-world problem: how to get medicines to people safely, quickly, and reliably—especially in a context like Pakistan, where infrastructure gaps exist. Your solution is both practical and forward-thinking.

What I appreciate:

• The “one item, one code” traceability system is brilliant. It’s like requiring every step in a math proof to be justified—no skipping logic, no hidden assumptions.
• Your mix of delivery options (O2O, cold chain, third-party logistics, self-pickup) shows you understand that real systems are messy and diverse—unlike many AI models that assume a perfect world.
• You wisely learn from the U.S. and Japan but adapt those lessons to local realities. That kind of contextual awareness is what makes systems actually work.

A few suggestions:

• What happens if sensor data is wrong, delayed, or even tampered with? Consider adding uncertainty-aware AI—for example, models that can say, “I’m not confident about this shipment’s temperature history,” and flag it for review.
• Imagine connecting this supply chain directly to the HDT. A diabetic patient’s digital twin could verify that their insulin stayed within the safe 2–8°C range during transit—tying logistics directly to treatment success.
• From a teaching perspective: your system is a perfect case study for students learning about trade-offs. How do you balance speed, cost, and safety? That’s real-world math and systems thinking in action.

Bringing It All Together

What excites me most is how your two papers—though focused on different scales—actually point toward a coherent vision:

• The HDT is the micro: deeply personal, individual care.
• The Pharma 4.0 supply chain is the macro: the infrastructure that makes that care possible.
• And self-supervised learning with causal and temporal reasoning is the bridge between them—allowing systems to learn from real-world experience while respecting both physical limits and human values.

In math education, we always say: abstraction without context is empty, but context without structure is chaotic. Your work strikes that balance beautifully. You’re not just building smarter algorithms—you’re designing systems that can explain, adapt, and ultimately empower people.

Thank you, Sergio Leal Ramirez.

Your insights have given me much to reflect on. The connection you draw between the human digital twin’s feedback loops and Vygotsky’s zone of proximal development resonates deeply with my vision of scaffolding patient learning in real time.

Exploring how the HDT might act as a learning partner by offering explanations alongside recommendations is exactly the next step I plan to take. Linking self-supervised pretraining on years of unlabeled health signals to causal reasoning could reveal the hidden relationships needed for robust counterfactual analysis.

I was also struck by your suggestion to incorporate uncertainty awareness into the pharmaceutical supply chain. I will investigate Bayesian layers and confidence quantification methods to flag anomalies and ensure greater reliability.

Your idea of using these systems as case studies for students learning about trade-offs in speed, cost, and safety is inspiring. Bringing together the micro-scale personalization of the HDT with the macro-scale logistics of Pharma 4.0 through self-supervised learning feels like a coherent path toward truly adaptive and explainable systems.

Thank you again for your generous critique. I look forward to continuing this conversation and learning from your expertise.

I would be grateful to you if you gave me your valuable review on my paper.
