The Journey of a Relentless Dreamer

In the highly competitive world of UPSC Civil Services Examination, where over 10 lakh candidates apply each year and only a handful make it to the final list, Ishita Kishore carved her name in gold. In 2022, she secured All India Rank 1, proving yet again that perseverance, strategy, and self-belief can achieve the seemingly impossible.

Her story is not just about topping UPSC. It’s a story of falling, rising, realigning, and conquering — a story that will inspire generations of aspirants.


Early Life and Family Background

Ishita Kishore was born in Begumpet, Hyderabad, and brought up in Patna, Bihar, before moving to Delhi NCR. Her father, Wing Commander Sanjay Kishore, served in the Indian Air Force, instilling in her values of discipline, service, and national pride. Her mother, Jyoti Kishore, is a retired school teacher and has been Ishita’s strongest emotional pillar.

Coming from a defence background, Ishita experienced structured environments and frequent relocations, which made her adaptable and emotionally resilient — qualities that would later become her strengths in UPSC preparation.


Academic Excellence at SRCC

Ishita completed her schooling from Air Force Bal Bharati School, New Delhi, where she actively participated in academics and sports. She then went on to study Economics Honours at Shri Ram College of Commerce (SRCC), Delhi University, one of India’s most prestigious institutions.

While SRCC typically opens doors to finance and consultancy careers, Ishita was quietly preparing for a life in public service.

  • Andrew Heywood’s Political Theory
  • Pavneet Singh’s IR
  • Previous years’ questions for pattern analysis

2. Daily Study Routine

Her day was planned meticulously:

  • 6:00 AM – 8:00 AM: Newspaper reading (The Hindu + Indian Express editorial)
  • 8:00 AM – 9:00 AM: Revision of previous day’s notes
  • 10:00 AM – 1:00 PM: Static GS topics or optional subject
  • 2:00 PM – 4:00 PM: Current Affairs, note-making
  • 5:00 PM – 7:00 PM: Practice mock answers or prelims test
  • 8:00 PM – 9:00 PM: Light reading, analysis, reflection

She emphasized consistency over intensity, studying around 8–9 focused hours per day.


Mains Answer Writing Practice

She joined multiple online platforms for daily answer writing. Initially, her answers were too lengthy or theoretical. But with peer reviews, toppers’ copies analysis, and expert feedback, she learned the art of balancing content with structure.

Her answer mantra:

“Think like a bureaucrat, write like a citizen.”

She also integrated current affairs into GS answers and supported arguments with constitutional provisions, case laws, or data.


Mental Health and Motivation

Like every aspirant, Ishita faced self-doubt, fatigue, and the pressure of expectations. During her low days, she followed:

  • Mindfulness meditation (10 mins daily)
  • Listening to motivational podcasts (e.g., IAS interviews, Gaur Gopal Das)
  • Talking to family, especially her mother, who kept her emotionally grounded

She also maintained a gratitude journal, where she listed 3 things she was grateful for daily. This helped keep perspective during hard times.

  20. Conclusion

1. Introduction

Overfitting occurs when a model performs well on training data but fails to generalize to unseen examples. In quantum machine learning (QML), overfitting arises due to overparameterized variational circuits, excessive entanglement, or insufficient training samples.

2. What Is Overfitting in Machine Learning?

  • High accuracy on training set
  • Poor performance on test/validation data
  • Model “memorizes” instead of learning patterns

3. Manifestation of Overfitting in Quantum Models

  • Low training loss, high validation loss
  • Quantum classifiers that learn noise in training measurements
  • Circuit configurations that are too expressive

4. Sources of Overfitting in Quantum Machine Learning

  • Too many variational parameters
  • Deep quantum circuits on small datasets
  • Poor encoding strategies
  • Insufficient shot counts (measurement noise)

5. Variational Quantum Circuits and Model Complexity

  • Like deep neural networks, VQCs can be overparameterized
  • More parameters → more capacity to memorize noise

6. Role of Circuit Depth in Overfitting

  • Deeper circuits often provide greater expressivity
  • But increase risk of overfitting, especially on small data

7. The Curse of Expressivity in QML

  • Highly expressive circuits can represent arbitrary functions
  • Without regularization, this leads to poor generalization

8. Quantum Generalization Theory: Early Insights

  • Still a developing field
  • Concepts like VC-dimension, Rademacher complexity being adapted for QML
  • Fidelity-based generalization bounds under study

9. Indicators of Overfitting in Quantum Workflows

  • Loss curves diverging after initial convergence
  • Overly sensitive circuit outputs to small input changes
  • Highly unstable gradients

10. Evaluating Generalization on Quantum Devices

  • Use separate validation set with fixed shot budget
  • Monitor variance across multiple runs

11. Regularization Techniques for Quantum Models

  • L2 weight decay
  • Circuit structure restrictions
  • Parameter sparsity

12. Parameter Norm Penalties (L2 Regularization)

Add to cost function:
\[
\mathcal{L}_{ ext{reg}} = \mathcal{L} + \lambda \sum_i heta_i^2
\]
Where \( heta_i \) are circuit parameters.

13. Early Stopping in Quantum Training

  • Stop optimization when validation loss increases
  • Helps prevent convergence to overfitted minima

14. Circuit Pruning and Parameter Dropout

  • Disable certain gates randomly during training
  • Reduce circuit size post-training by removing low-contribution parameters

15. Noise-Injection as a Regularizer

  • Add controlled noise to circuit outputs or parameters
  • Mimics classical dropout

16. Ensemble Learning in Quantum Circuits

  • Average predictions from multiple small VQCs
  • Reduces variance and improves robustness

17. Cross-Validation in Quantum Learning

  • k-fold or leave-one-out strategies adapted for QML
  • Evaluate circuit generality over multiple splits

18. Hybrid Regularization Strategies

  • Combine classical regularizers with quantum-specific constraints
  • e.g., depth limits + weight decay + early stopping

19. Research on Generalization Bounds in QML

  • Ongoing research in quantum PAC learning
  • Fidelity-based loss bounds, entropic capacity metrics
  • Open question: What governs the learnability of QNNs?

20. Conclusion

Quantum models, like their classical counterparts, are prone to overfitting. Regularization techniques such as early stopping, L2 penalties, circuit pruning, and hybrid strategies can enhance generalization, ensuring quantum systems not only learn but also perform reliably on unseen data.
