# --description--

The next few video lessons will reference [this Colab notebook](https://colab.research.google.com/drive/1ZZXnCjFEOkp_KdNcNabd14yok0BAIuwS#forceEdit=true&sandboxMode=true).

# --questions--

## --text--

Dense neural networks analyze input on a global scale and recognize patterns in specific areas. Convolutional neural networks...:

## --answers--

also analyze input globally and extract features from specific areas.

---

do not work well for image classification or object detection.

---

scan through the entire input a little at a time and learn local patterns.
