How can we generate counterspeech that doesn't just oppose hate, but understands its underlying claims and responds with the right strategy and supporting evidence?

@prajdabre A senior area chair cannot be an area chair. If it happens there is a glitch and should be reported.

🚨 New article: From Scaling Laws to Downscaling Laws

https://t.co/dq3ISvm8iK

In 2025 we argued at ICML that the field needs downscaling laws.
In 2026 we deliver one at EMNLP.

A 10% lower loss costs 4–8× the carbon emission.
Pruning 43% of a model keeps 70% of its performance, with zero retraining.

Scaling up is expensive. Scaling down is predictable.

📝Submission deadline to ARR is Jan 4, 2027.
⭐️ACL2027 Theme Track is "Homogenization and knowledge collapse in LLMs".

[Tanmoy Chakraborty @Tanmoy_Chak]

Honoured to host the legendary Prof. @liuhuan and Prof. Longbing Cao at our lab @lcs2lab @iitdelhi today!

Our entire lab had a wonderful opportunity to interact with them and receive their invaluable feedback. And Prof. Huan’s sense of humour is simply out of this world! ☺️

[Tanmoy Chakraborty @Tanmoy_Chak]

In knowledge distillation (KD), teachers hallucinate, and standard KD forces the student to copy them anyway, spending probability mass on the teacher's noisy, low-confidence predictions and overwriting priors the student already had right. Our fix, CaRE-KD (accepted at #NeurIPS2026), makes the student decide when to trust the teacher. At the token level, a confidence gate switches between mean-seeking and mode-seeking divergence depending on how sure the teacher is. At the sequence level, a rejection mechanism drops updates where the teacher is epistemically less reliable than the student.

India has engineers building the AI frontier. Why are we still behind it?

Prof. Tanmoy Chakraborty (@Tanmoy_Chak), IIT Delhi, on private investment, the talent we already have, and why India should keep building.

A few highlights from our conversation.

[Tanmoy Chakraborty @Tanmoy_Chak]

I appeared on @TV9Bharatvarsh to discuss how AI could potentially devise plans to harm humans and what this means for AI safety.
