Time is of the essence. If you need a fast turnaround for 2026, I have filtered the list for conferences that offer rapid review cycles (notification within 2–4 weeks) or explicitly market "fast track" publication options.

All selected events are confirmed to be associated with Scopus and Ei Compendex publishers (Springer, ACM, IEEE).

Fastest Review (Notification in 2–4 Weeks)

These conferences prioritize speed. They are ideal if you have a hard deadline for graduation or funding.

1. ICTIS 2026 (11th Intl. Conf. on ICT for Intelligent Systems)

This is a popular choice in Asia for its reliable Springer publication and quick processing.

• Location: Bangkok, Thailand

• Conference Date: April 9–11, 2026

• Review Speed: Typically 3–4 weeks after submission.

• Publisher: Springer (Lecture Notes in Networks and Systems - LNNS).

• Indexing: Scopus, Ei Compendex, INSPEC.

• Deadline: Final round submissions are often accepted until mid-February 2026.

2. ICCSCM 2026 (15th Intl. Conf. on Computer Science & Computational Mathematics)

Known for an extremely fast administrative check and review process.

• Location: Melaka, Malaysia (Hybrid)

• Conference Date: February 12–13, 2026 (Likely too late for Feb, but look for the next round in late 2026 as they run frequent cycles).

• Review Speed: Notification often sent 1 week after submission (very fast).

• Publisher: Scopus-indexed journals (Special Issues).

• Note: Because the review is very fast, ensure you double-check the specific journal they assign you to for its current Scopus status.

3. ICASET 2026 (5th Intl. Conf. on Advances in Science, Engineering & Technology)

• Location: Chennai, India

• Conference Date: March 22–23, 2026

• Review Speed: 2–3 weeks.

• Focus: Interdisciplinary (Science, Engineering, Tech).

• Indexing: Scopus & WoS (via associated journals/proceedings).

• Deadline: Rolling submissions through February 2026.

• Website: icaset.in

Reliable & Efficient (Notification in ~2 Months)

These are "Mid-to-High Tier" conferences. They are not "instant," but they are much faster than journals and offer very stable indexing (ACM/IEEE).

4. ICBDE 2026 (International Conference on Big Data Engineering)

Widely considered a "safety net" for Big Data researchers due to its stable ACM history.

• Location: (Likely China or Japan, rotates annually)

• Conference Date: May/June 2026

• Review Speed: 4–6 weeks.

• Publisher: ACM (Association for Computing Machinery).

• Indexing: Ei Compendex, Scopus.

• Why it's good: ACM proceedings are typically indexed very quickly (3–6 months after the event).

• Website: Check icbde.org for the 2026 call.

5. ICMLC 2026 (18th Intl. Conf. on Machine Learning and Computing)

A long-standing conference with a massive track record.

• Location: Shenzhen, China (TBC)

• Conference Date: July 2026

• Review Speed: 4–6 weeks.

• Publisher: ACM (International Conference Proceedings Series).

• Indexing: Ei Compendex, Scopus.

• Deadline: Submission window usually closes in March/April 2026.

• Website: icmlc.org

Speed vs. Safety Warning

• Predatory Flags: Be cautious of any conference promising acceptance in under 3 days. A legitimate peer review (even a fast one) needs at least 1–2 weeks.

• "Journal Publication": If a conference promises publication in a Scopus Journal (rather than Proceedings), ask for the specific ISSN of the journal before you pay. Ensure that specific journal is still active in Scopus.

Recommendation: For the best balance of speed and safety, ICTIS 2026 (Springer) or ICBDE 2026 (ACM) are your safest bets for a quick 2026 publication.
