+ # ColD Fusion model
9
+
10
+ Finetuned model that aims to be a great base model. It improves over RoBERTa base, trained on 35 datasets.
11
+ Full details at [this paper](https://arxiv.org/abs/2212.01378).

+ ## Paper Abstract:
14
+
15
+ Pretraining has been shown to scale well with compute, data size and data diversity. Multitask learning trains on a
16
+ mixture of supervised datasets and produces improved performance compared to self-supervised pretraining. Until now,
17
+ massively multitask learning required simultaneous access to all datasets in the mixture and heavy compute resources
18
+ that are only available to well-resourced teams.
19
+
20
+ In this paper, we propose ColD Fusion, a method that provides the benefits of multitask learning but leverages distributed
21
+ computation and requires limited communication and no sharing of data. Consequentially, ColD Fusion can create a synergistic
22
+ loop, where finetuned models can be recycled to continually improve the pretrained model they are based on. We show that
23
+ ColD Fusion yields comparable benefits to multitask pretraining by producing a model that (a) attains strong performance on
24
+ all of the datasets it was multitask trained on and (b) is a better starting point for finetuning on unseen datasets. We find
25
+ ColD Fusion outperforms RoBERTa and even previous multitask models. Specifically, when training and testing on 35 diverse datasets,
26
+ ColD Fusion-based model outperforms RoBERTa by 2.45 points in average without any changes to the architecture.

+ ### How to use
30
+ Best way to use is to finetune on your own task, but you can also extract features directly.
31
+ To get the features of a given text in PyTorch:
32
+
33
+ ```python
34
+ from transformers import RobertaTokenizer, RobertaModel
35
+ tokenizer = RobertaTokenizer.from_pretrained('ibm/ColD-Fusion')
36
+ model = RobertaModel.from_pretrained('ibm/ColD-Fusion')
37
+ text = "Replace me by any text you'd like."
38
+ encoded_input = tokenizer(text, return_tensors='pt')
39
+ output = model(**encoded_input)
40
+ ```
41
+
42
+ and in TensorFlow:
43
+
44
+ ```python
45
+ from transformers import RobertaTokenizer, TFRobertaModel
46
+ tokenizer = RobertaTokenizer.from_pretrained('ibm/ColD-Fusion')
47
+ model = TFRobertaModel.from_pretrained('ibm/ColD-Fusion')
48
+ text = "Replace me by any text you'd like."
49
+ encoded_input = tokenizer(text, return_tensors='tf')
50
+ output = model(encoded_input)
51
+ ```
52
+

+ ## Evaluation results
54
+ See full evaluation results of this model and many more [here](https://ibm.github.io/model-recycling/roberta-base_table.html)
55
+ When fine-tuned on downstream tasks, this model achieves the following results:
