[Python] Predict the next word on the web or mobile app? [closed]

I am starting a project related to text prediction, specifically focusing on building a Next Word Prediction Model. My objective is to utilize past text inputs to predict the next word a user is likely to type.

1. 
   Model Selection Which model should I use? Should I consider using LSTM, GRU, or Transformer architectures for this task? What are the advantages and disadvantages of each model in the context of next word prediction?
   
   
2. 
   Data Preparation Data as-is or Preprocessing?
   

Should I use the raw text data as-is, or should I preprocess it (e.g., tokenization, lowercasing, removing punctuation) before feeding it into the model?

If I decide to preprocess, which techniques would be most effective in improving model performance?

1. Input Representation Word Embeddings vs. One-Hot Encoding:

Should I use pre-trained word embeddings (like Word2Vec or GloVe) for input representation, or would one-hot encoding suffice?

If I use embeddings, how can I ensure they capture the semantic relationships between words effectively?

1. Sequence Length How to Handle Sequence Length?

What should be the optimal sequence length for the input text? How can I determine the right length without losing important context?

Should I pad sequences to a fixed length, and if so, what padding strategy would be best (e.g., pre-padding, post-padding)?

1. Model Training Hyperparameter Tuning:

What hyperparameters should I focus on tuning (e.g., learning rate, batch size, number of layers) to achieve the best performance?

How can I effectively use techniques like cross-validation to validate the model's performance during training?

1. Evaluation Metrics Which metrics should I use to evaluate the model?

Should I use accuracy, perplexity, or BLEU score to measure the performance of the Next Word Prediction Model? How do these metrics reflect the model's predictive capabilities?

1. Deployment How can I deploy the model in a mobile application?

What are the best practices for optimizing the model for inference on mobile devices? Should I consider model quantization or pruning?

1. Predicting the Next Word on the Web How can I implement Predict the next word on the web?

If I want to deploy the next word prediction model on the web, what factors should I consider?

Are there any differences in how the model operates in a web environment compared to a mobile application? What APIs should I use to connect the model with the user interface?
