5 GPU & vGPU Mistakes That Break VMware Private AI Foundation (and How to Fix Them)
Most failed VMware Private AI Foundation deployments break on host-side GPU configuration, not the model. Here are five vGPU mistakes in VCF 9.1 and the exact commands to confirm and fix each one.

Introducing the AI Infrastructure Sizing & Cost Calculator
Over the past few months, I have been spending a lot of time exploring on AI infrastructure around VMware Private AI, NVIDIA AI Enterprise, RAG, Agentic AI, and AIOps. One question that comes up repeatedly is: “How much infrastructure do we actually need, and what will it cost?” Is there any sizing calculator that we…

ML Concepts – Evaluation Matrix and Equations
There are several classifiers can be used to identify the model’s effectiveness. You can assess using the evaluation metrics such as Accuracy, Recall, F1 Score, Precision, False Positive Rate (FPR), and True Positive Rate (TPR). Equations for these metrics are showing below.

ML Concepts – Loss Function in ANN
The Loss Function is one of the important components of Neural Networks. Loss is nothing but a prediction error of Neural Net. And the method to calculate the loss is called Loss Function.In simple words, the Loss is used to calculate the gradients. And gradients are used to update the weights of the Neural Net.…

ML Concepts – Understanding the Dataset
What is Dataset? Usually dataset refers to the data that you have, it is combined of both dependent as well as independent variables. In ML lingo, dataset is the pair (X, y) where X refers to set of independent variables and y is the target. X is also called the feature set. Moreover, using variables/features…

ML Concepts – Classification vs Regression
Classification Regression – Classification is the task of predicting a discrete class label.– In a classification problem data is labelled into one of two or more classes.– A classification problem with two classes is called binary, more than two classes is called a multi-class classification.– Classifying an email as spam or non-spam is an example…

ML Concepts – Encoding Categorical Data
There are two types of encoding the Categorical Data: One Hot Encoding Label Encoding or Target Encoding Example: One Hot Encoding – 100, 101, 010 Label Encoding – Normal = 0, Malicious = 1

ML Concepts – ROC vs AUC
ROC (Receiver Operating Characteristic) AUC (Area Under Curve) – ROC Curve represents relationship between Recall and Specificity. – It is a performance measurement for the binary classification. – It is probability curvet plotted with TPR against the FPR. – AUC Curve represent the degree of measure of separability. – Higher the AUC, the better the…

ML Concepts – What is Feature Scaling?
Feature Scaling Feature scaling is technique that will get mean and standard deviation of your feature in order to scale your feature. If we apply the feature scaling before the splitting the dataset, then it takes the mean and standard deviation of all the values including training set. It will cause the information leakage. We…
