A P-value is the probability of obtaining an effect at least as extreme as the one in your sample data, assuming the truth of the null hypothesis

#DataScience #MachineLearning #100DaysOfMLCode #Python #DataScientist #Statistics #programming #Data #DataAnalytics #AI #Math
P values address only one question:

How likely are your data, assuming a true null hypothesis ?

#DataScience #MachineLearning #100DaysOfMLCode #Python #DataScientist #Statistics #programming #Data #DataAnalytics #AI #Math #Stat #Python #learning #LearnToCode
If P value is more than significance level we accept the null hypothesis or fail to reject it,

#DataScience #DeepLearning #MachineLearning #100DaysOfMLCode #Python #DataScientist #Statistics #programming #Data #DataAnalytics #pythoncode #AI #Pandas #programming #Math
If p value is less than the chosen significance level then you reject the null hypothesis for the entire population i.e. accept that your sample gives reasonable evidence to support the alternative hypothesis.

Image interpolation occurs when you resize or distort your image from one pixel grid to another.

1/n

#computervision #IMAGE #DataScience #MachineLearning #DeepLearning #100DaysOfMLCode #Python #programming #Math #Stat #dataviz #DataAnalytics #AI #ArtificialIntelligence #data
Image interpolation works in two directions, and tries to achieve a best approximation of a pixel's intensity based on the values at surrounding pixels.

2/n

#computervision #IMAGE #DataScience #MachineLearning #DeepLearning #100DaysOfMLCode #Python #programming #Math #Stat
Image resizing is necessary when you need to increase or decrease the total number of pixels, whereas remapping can occur when you are correcting for lens distortion or rotating an image.

Thanks @braveproductguy for sharing this set of Cognitive biases in #software #engineering
A. 𝐀𝐧𝐜𝐡𝐨𝐫𝐢𝐧𝐠 𝐚𝐧𝐝 𝐚𝐝𝐣𝐮𝐬𝐭𝐦𝐞𝐧𝐭 𝐛𝐢𝐚𝐬 - work fills up the space you allot to it. Use budgets instead of estimates to build a quality feature

@braveproductguy B. 𝐀𝐧𝐜𝐡𝐨𝐫𝐢𝐧𝐠 𝐚𝐧𝐝 𝐚𝐝𝐣𝐮𝐬𝐭𝐦𝐞𝐧𝐭 𝐛𝐢𝐚𝐬 - Missing links, lack of readability and documents leads people to use their own understanding of the system thereby making insufficient modifications.
@braveproductguy C. 𝐀𝐧𝐜𝐡𝐨𝐫𝐢𝐧𝐠 𝐚𝐧𝐝 𝐚𝐝𝐣𝐮𝐬𝐭𝐦𝐞𝐧𝐭 𝐛𝐢𝐚𝐬 - Initial solution design or architecture design does not evolve sufficiently to accommodate new changes, requests or constraints. Developers who anchor on existing solutions tend to include unnecessary features.
