What this project is about

This page compares Flatten, Bidirectional LSTM, Bidirectional GRU, and Conv1D on the same IMDB sentiment problem. It is an architecture tradeoff experiment.

Implementation focus

The lesson was not that one model always wins. The value is comparing speed, order-awareness, local pattern detection, overfitting, and validation behavior.

Key results and artifacts

Shared vocabulary size: 10,000
Sequence length: 120
All models trained for 10 epochs
Visible overfitting across architectures

What I learned

This became an architecture intuition lab: order-insensitive baselines, recurrent models, and local-pattern Conv1D models each fail and succeed differently.

Milestone deep dive

What this project proves in my learning path.

A model-comparison lab that tests Flatten, Bidirectional LSTM, Bidirectional GRU, and Conv1D architectures on the same IMDB sentiment task. The milestone is included because it shows a complete learning unit: a problem, a data representation, an implementation path, measurable outputs, and a lesson that later connects to larger AI systems.

Problem framing

What I was trying to solve

This page is not just a lab description. It explains how I transformed the assignment idea into an engineering story: what the model receives, what it optimizes, what output it should produce, and how the result can be inspected.

Implementation

What I coded or assembled

The implementation focus was the mechanism behind the result: functions, model blocks, training logic, preprocessing, evaluation, and the small technical details that make the notebook work rather than only look correct.

What changed after it

This became an architecture intuition lab: order-insensitive baselines, recurrent models, and local-pattern Conv1D models each fail and succeed differently.

How I would explain it in an interview

I would describe this milestone by starting from the data representation, then explain the model or algorithm, then show what was measured. The important part is not only the final number; it is the ability to reason about why the method works, what assumptions it makes, and what limitations should be improved next.
