In a previous post, I introduced the theory behind the method of least squares and showed how it can be used to solve systems of equations with no unique solution.Now, I want to look at one of its most practical
If you recall, the binary search Python algorithm inspects the middle element of a bounded range in a sorted collection. But how is that middle element chosen exactly? Usually, you take the average of the lower and upper boundary to find the middle index: Python middle = (left + right)...
Its emphasis on readability and simplicity allows new programmers to quickly grasp the language and start writing code with a minimal learning curve. Extensive libraries— Python has a vast ecosystem of libraries and packages that can be easily imported, streamlining the development process. These ...
In simple terms, cloud computing refers to delivering computing services such as storage, processing power, and applications over the Internet. I always like to give this example: imagine that instead of having your computer, you rent a powerful one from providers like Amazon Web Services (AWS...
If you're short on time and want to know how to learn AI from scratch, check out our quick summary. Remember, learning AI takes time, but with the right plan, you can progress efficiently: Months 1-3: Build foundational skills in Python, math (linear algebra, probability, and statistics...
The area under the curve (AUC) can be used as a summary of the model skill. The shape of the curve contains a lot of information, including what we might care about most for a problem, the expected false positive rate, and the false negative rate. To make this clear: Smaller values ...

I am not able to supply the gradients analytically while curve fitting both real and imaginary data (lsqcurvefit). To be more specific I have several real and imaginary data sets with 5 shared parameters but with different objective functions, for example ...
Sometimes, your data might not fit well with a linear trendline. In such cases, a polynomial trendline can provide a better fit. Here’s how to add a polynomial trendline using Matplotlib: importnumpyasnpimportmatplotlib.pyplotasplt# Sample datax=np.array([1,2,3,4,5])y=np.array([2,3...
there is also a code section that fit a circle by the Taubin method (at least 4 to 5 points are needed, whereas the curvature is computed on 3 points) required functions are provided in attachment hope it helps ! method with cercle fit : Radius scatter plot the R value ...
