2. TensorFlow Core API:
   • Proficiency in using TensorFlow Core API for tasks such as defining computational graphs, creating tensors, executing operations (e.g., addition, multiplication), and understanding the TensorFlow execution model (e.g., sessions, graphs).
3. TensorFlow Keras API:
   • Experience with TensorFlow's Keras API, which provides high-level building blocks for defining and training deep learning models. Skills in building neural networks (e.g., sequential models, functional API), configuring layers (e.g., dense layers, convolutional layers), and compiling models with optimizers and loss functions.
4. Model Training and Evaluation:
   • Techniques for preparing data, preprocessing (e.g., normalization, scaling), splitting data into training, validation, and test sets, defining model architectures, compiling models, training models using fit() method, evaluating model performance using metrics (e.g., accuracy, loss), and improving model performance through hyperparameter tuning.
5. Transfer Learning and Fine-tuning:
   • Knowledge of transfer learning techniques using pre-trained models (e.g., VGG, ResNet, BERT) from TensorFlow Hub or TensorFlow Model Garden, fine-tuning models on new datasets, freezing and unfreezing layers, and adapting models to specific tasks.
6. TensorFlow Estimators:
   • Familiarity with TensorFlow Estimators API for building scalable and distributed machine learning models, including using pre-made Estimators (e.g., LinearRegressor, DNNClassifier) and creating custom Estimators for specific tasks.
7. TensorFlow Serving and Deployment:
   • Skills in deploying TensorFlow models to production using TensorFlow Serving, Docker containers, or TensorFlow Lite for mobile and embedded devices. Understanding of serving models via RESTful APIs, handling model versioning, and monitoring model performance.
8. TensorFlow Data Pipeline:
   • Techniques for building efficient data input pipelines using TensorFlow Dataset API, reading data from various sources (e.g., CSV files, databases), preprocessing data (e.g., batching, shuffling), and optimizing data loading for model training.
9. TensorFlow GPU Acceleration:
   • Experience in leveraging GPU acceleration with TensorFlow for faster model training and inference. Knowledge of configuring TensorFlow to utilize GPUs (e.g., CUDA, cuDNN), monitoring GPU usage, and optimizing TensorFlow code for GPU performance.
10. TensorFlow Extended (TFX):
    • Awareness of TensorFlow Extended (TFX) for end-to-end machine learning pipelines, including data validation, preprocessing, model training, model analysis, and serving. Understanding of TFX components and workflow orchestration using Apache Beam.
11. TensorFlow Model Interpretability:
    • Ability to interpret TensorFlow models, analyze model predictions, visualize model outputs (e.g., confusion matrices, ROC curves), and explain model decisions using techniques such as SHAP (SHapley Additive exPlanations) or integrated gradients.
