Deep neural nets: foundational python intro

According to learners, this course offers a solid foundational understanding of Deep Neural Networks in Python. Reviews frequently highlight the clear explanations of core concepts like perceptrons and gradient descent, calling them easy to follow. Many students valued the hands-on Python implementation using NumPy, which helps build understanding from scratch. However, a key point is that this course is not ideal for absolute beginners. Despite the title, it requires prior knowledge of Python and basic math. Learners without this background may find the pace too fast. The focus on NumPy implementation is good for theory but means modern frameworks are not covered, which some learners noted as a limitation for practical use. Overall, feedback is largely positive, especially for those meeting prerequisites.

Pace suitable for those with background.

"The pace was just right for me, having some prior coding experience."

"Found the pace a bit too fast, especially in the later optimization sections."

"If you meet the prerequisites, the step-by-step pace is excellent."

"Might feel rushed if you're learning Python and DNN concepts simultaneously."

Uses NumPy, not modern ML libraries.

"Building with just NumPy is great for learning the fundamentals without abstraction."

"It's good for understanding the 'under the hood' but lacks practical experience with TensorFlow or PyTorch."

"While the NumPy approach is insightful, I wish it had included a section on modern frameworks."

"Excellent for understanding the math behind DNNs by implementing everything in NumPy."

Offers hands-on implementation with code.

"Coding the models from scratch using NumPy really helped solidify my understanding of the math."

"The practical sessions after the theory were essential for applying what I learned."

"Building a simple neural network step-by-step in Python was the most valuable part for me."

"Loved the hands-on coding exercises; they reinforced the theoretical lessons effectively."

Core deep learning concepts explained well.

"The explanations of perceptrons and gradient descent were incredibly clear and easy to follow."

"I finally understood how neural networks work after taking this course, thanks to the step-by-step approach."

"The early modules did a great job building up the concepts from basic linear equations and error functions."

"Complex topics are broken down into understandable parts, making the theory accessible."

Needs prior Python and math knowledge.

"This course is NOT for absolute beginners... you need a solid grasp of Python and some linear algebra basics."

"While titled 'Beginners', it moves quickly and assumes familiarity with NumPy and calculus concepts."

"I struggled early on because my Python was weak; the 'basic understanding' requirement is crucial."

"Definitely requires more than a 'basic' understanding of Python to keep up with the coding sections."
